Description

Enhanced visual cues for scented laundry detergents

This invention relates to scented granular laundry detergent compositions containing visual contrast signals made from colored and molded film material.

Background

10 It is customary to include perfume in perfumed laundry detergent compositions. These products are appreciated by the consumer as a result of their smell. The smell on the package, the smell when using it and the smell on the clothes before and after drying and / or ironing have been the subject of much research and many patents. Possibly, the name of the variant or the way in which the product is marketed provides an indication of the type of perfume of a given composition. It is desirable to provide better information on the type of perfume of the

15 composition

Recently, publications have appeared that relate the perception of odors to form and color. In Neuron, Vol. 39, 375-386, of July 17, 2003. "The Nose Smells What the Eye Sees: Crossmodal Visual Facilitation of Human Olfactory Perception"; Jay A. Gottfried and Raymond J. Dolan reported: The human sense of smell is unreliable when acting on its own. You need visual cues to be more precise. The underlying brain network involved in this olfactory and visual process was studied. The brain activity of the subjects was monitored by MRI when they perceived stimuli for smell and sight. The stimuli were manipulated in various combinations and the brain changes of the subjects were monitored. The researchers found that visual cues have an impact on olfactory cues recorded in the frontal part of the cerebral hippocampus and cortex.

25 orbitofrontal rostromedial brain.

In J Neurophysiol 93: 3434-3441, 2005. "Color of Scents: Chromatic Stimuli Modulate Odor Responses in the Human Brain", by Robert A. Österbauer, Paul M. Matthews, Mark Jenkinson, Christian F. Beckmann, Peter C. Hansen and Gemma A. Calvert, it was reported that: color has a profound effect on the perception of odors. 30 For example, strawberry-flavored drinks are considered to smell more pleasant when they are red than when they are green. In addition, the descriptions of the "buque" of a wine are strongly influenced by its color. Color signals affect smell, as seen by changes in brain activity in the caudal regions of the orbitofrontal cortex of the brain. In these experiments, various combinations of odors (lemon, strawberry, mint or caramel) and colors (yellow, red,

35 turquoise or brown). When a color and a smell matched what was expected, such as a yellow color along with a lemon smell, there was more activity in regions of the brain that process olfactory information than when the smell was provided alone. Odors and colors that did not correspond produced less brain activity.

Therefore, actions such as the addition of red to white wine can alter how a person perceives the smell of wine (and the publication revealed how we can observe the brain while this occurs).

In GB 2358403 A, colored water soluble plastic film particles are added to a contrasting colored powder laundry detergent. Examples of this patent application use 5 mm diameter star or circular film particles. Document GB 2358403 A also discloses that

45 visual cues may properly have other regular and symmetrical shapes, such as squares and triangles. As an alternative to the use of identical shapes, sets of shapes are suggested that correspond, for example, geometric shapes: triangles, squares, pentagon and hexagons; numbers; letters of the alphabet; celestial bodies: sun, moon and stars.

In WO 2006/079416, 0.1% of colored visual cues made from gum arabic film are added to a powdered laundry detergent. Arabic gum cues are irregularly shaped and are produced by fragmenting a large film of the appropriate material. When the film material breaks in this way, it results in random shapes with sharp angles, usually with a triangular or "pointed" appearance.

It is an object of the present invention to produce an improved visual signal that can aid in the identification and appreciation of a scented scent in a laundry detergent composition, especially a powder casting composition.

60 It is also an objective to provide a granular laundry detergent composition comprising perfume and colored and molded visual cues that contribute to an improved washing process experience.

Definitions

65 Visual signal Means a point of differentiation perceptible by the consumer in a detergent composition. This could be a characteristic of the bulk composition: p. eg, color, viscosity, granule size, or could be achieved by including visually distinct particles in the composition, in a smaller amount.

5 Visual signal particle

It means a speck, film particle or other colored solid that contrasts visually added to a detergent composition in a smaller amount to function as a visual signal.

10 Laminar visual signal (or lamellae)

It means visual signal particles in the form of flat film material that are shaped. The shapes can be cut from a sheet or film or can be molded directly. Such lamellae are also called "film particles."

15 Flower shape (or flower type)

It means flat film forms (or lamellae) that have the contour of the shape of a flower with petals that has a generally circular central area with six symmetrically distributed "petals" that split

20 from her.

Summary of the invention

In accordance with the present invention there is provided a granular laundry detergent composition which

25 comprises at least 5% by weight of surfactant, optional detergency builder, optional additional cleaning ingredients, a perfume and 0.01 to 10% by weight of visual cues, in which the visual signal is flower-shaped with petals colored to have a natural petal color, in which the perfume is a floral perfume.

30 The colors of the visual signal are selected from the group comprising: yellow, red, blue, lilac, violet, orange, purple and green colors.

The visual signals have a diameter between 2 mm and 10 mm.

Advantageously, the visual signals are formed of colored soluble film material with a maximum thickness of 1 mm, preferably 0.4 mm, most preferably 0.25 mm, most preferably 0.2 mm.

Preferably, the visual signals have a relative density of less than 0.8, preferably 0.5, the most

40 preferably 0.4. This guarantees that the visual signals float and contributes to the continuous provision of a visual signal for the perfume, even during washing.

The advantage of these visual cues lies in their improved efficiency to reinforce and transmit the attributes of the perfume to the user. This in turn contributes to an improved washing procedure experience and has been

45 demonstrated that it even results in an enhanced perception of cleanliness and freshness of washed fabrics.

Detailed description of the invention

50 In order to provide an effective visual signal for perfume, it is desirable that the petals are evenly distributed in a detergent composition, so segregation should not be too large. This is especially significant when the signal is used in a powder detergent composition.

The petal-shaped visual cues are not unduly segregated during mixing, handling and

55 transport. Segregation would lead to dosing variability unacceptable to consumers. At the level of segregation observed, the consumer accepts it. In addition, there is evidence that the level of segregation experienced has, in fact, a positive effect on the result, due to the 'surprise' factor. This can be quantified experimentally by reflectance measures.

Each visual signal preferably has a weight of> 1 mg and <4 mg, more preferably between 1.5 and 3.5 mg, and a relative density of> 200 and <500, preferably between 250 and 400 is highly advantageous for the petals.

The invention also encompasses the use of two or more completely different petals in a composition. Advantageously, these will have been cut from different films and can be of different colors, as well

65 as of different shapes and / or sizes.

The film from which the signal is manufactured may be scented itself and / or may incorporate other ingredients beneficial for washing and / or designed to enhance the effect of the visual signal. These may include fluorescent agents, pearled materials, iridescent materials, reflective materials, profragances, material with tactile benefits such as glycerin, materials that provide benefits for the

5 skin care, such as Aloe Vera.

Some ingredients (fluorescent agents) may increase the effect of the visual signal. It is also possible to include a low level of dye to counteract the yellowing. Matting dye provides a real benefit in washing. Aloe Vera could also be included in this way.

Other functional ingredients that can be used in the petals are TAED, gerol, DTI-1, enzymes, shading dye and perfume. The most preferred ingredients for use in films are those that only need to be present at very low levels in the powder formulation, especially perfume, shading dye, bleaching catalysts, fluorescent agents. Such materials may be unstable in detergents 15 due to the interaction with moisture and other ingredients. The film also allows a greater range of soluble dyes to use than was possible for specks. It also offers the advantage that there is very little

or no exudation of the dye in the powder mass. Soluble dyes are preferred to pigments, since they do not dye fabrics.

For the incorporation of sensitive ingredients in the film, it is advantageous that the film contains polyvinyl alcohol (PVA).

Preferred film materials comprise water soluble polymer, surfactant and dye. Other optional ingredients are: supplements to help in the production of the film, for example, agents of

25 release and water. In addition to its effect of controlling the relative humidity of the film, water also helps to confer plasticity to the film and regulates its solubility.

The polymer can be selected from among water-soluble film-forming polymers, especially those used in the formulation of powder detergents. Preferred polymers include polymers that dissolve and / or disperse completely in water in 30 minutes with stirring at a temperature at any point in the range of 293 to 333 K.

Preferred water soluble polymers are those capable of being molded to give a solid film or mass, for example as described in Davidson and Sittig, Water-Soluble Resins, Van Nostrand Reinhold Company,

35 New York (1968). Preferred water-soluble resins include polyvinyl alcohol, cellulose ethers, polyethylene oxide, starch, polyvinyl pyrrolidone, polyacrylamide, polyvinyl methyl ether-maleic anhydride, polymoleic anhydride, maleic anhydride styrene, hydroxyethylcellulose, polyxypropylmethylcellulose, hydroxypropylmethylcellulose, carboxylic acid methylcellulose , alginates, acrylamide copolymers, guar gum, casein, series of maleic-ethylene anhydride resins, polyethyleneimine, ethyl hydroxyethylcellulose, ethyl methylcellulose, hydroxyethyl methylcellulose, sugars. Poly-alcohol, water-soluble, low molecular weight film-forming resins are preferred.

Preferred polyvinyl alcohols for use therein have any average molecular weight between 1,000 and 1,000,000, preferably between 5,000 and 250,000, for example, between 15,000 and 150,000. Hydrolysis, or alcoholysis, is defined as the percentage of completion of the reaction when the acetate groups of the resin are replaced with

45 hydroxyl groups, -OH. A hydrolysis range of 60-99% of the polyvinyl alcohol film forming resin is preferred, although a hydrolysis range of approximately 70-90% is more preferred for polyvinyl alcohol film forming resins. The most preferred hydrolysis range is 80-89%. As used in this application, the term "polyvinyl alcohol" includes polyvinyl acetate compounds with hydrolysis levels disclosed herein.

Another suitable polymer is a polyvinyl alcohol film, made of a polyvinyl alcohol copolymer having a comonomer with a carboxylate function.

The preferred grade of PVA incorporates water only at an RH well above that of detergent compositions

55 granular. In this way, it protects the other components of the film from water decomposition and soluble dyes from exudation.

The visual signal film particle may comprise 10 to 80% polymer or polymer blend.

Although any suitable surfactant or surfactant system can be used, preferably, the surfactant is an anionic surfactant, especially if the granular composition comprises a detergency builder.

Suitable anionic surfactants included are well known to those skilled in the art. Examples of highly foaming sulphonate or sulfate surfactants include alkylbenzene sulphonates, particularly 65 linear alkylbenzene sulphonates with a linear chain length of C8-C15; primary and secondary alkyl sulfates, particularly primary C8-C15 alkyl sulfates; olefin sulfonates; alkylxylene sulfonates;

dialkyl sulfosuccinates; and fatty acid ester sulfonates. Sodium salts are generally preferred.

More information is given in the open access bibliography, for example, in "Surface-Active Agents and Detergents", volumes I and II, by Schwartz, Perry and Berch.

The preferred anionic surfactants are alkylbenzene sulfonates, more especially linear alkylbenzene sulfonate (LAS), which is preferably present in an amount of 12 to 24% by weight, more preferably 12 to 22% by weight and especially 15 to 15 22% by weight.

Even more preferred are primary alcohol sulfates (PAS), particularly C8-C18 primary alcohol sulfates, preferably C12-C15. A particularly preferred surfactant is primary alcohol sulfate (PAS) with a carbon chain length of 12. Visual signal film particles containing up to 50% PAS can be used.

The film may additionally include a second surfactant. The second surfactant is preferably selected from amphoteric surfactants, dipole surfactants, nonionic surfactants and ethoxylated anionic surfactants.

The second preferred amphoteric surfactants are amine oxides. The most preferred amide oxide is coconut dimethylamine oxide. The second preferred dipole surfactants are betaines, and especially amidobetaines, for example, coco amidopropyl betaine.

Preferred second non-ionic surfactants include primary and secondary alcohol ethoxylates, especially ethoxylated C8-C20 aliphatic alcohols with an average of from 1 to 20 moles of oxide.

25 ethylene per mole of alcohol, and more especially the primary and secondary aliphatic alcohols of C10-C15 ethoxylated with an average of from 1 to 10 moles of ethylene oxide per mole of alcohol.

The second preferred ethoxylated anionic surfactants include alkyl ether sulfates (ethoxylated alcohol sulfates).

Also suitable for use as second surfactants in the visual cues of the present invention are C8-C18 alkyl monoethanolamides, for example, coconut monoethanolamide.

The second surfactant system used in the film particle may additionally comprise smaller amounts of cationic surfactant, e.g. eg, less than 5% of the movie.

The surfactant can be included in the film at a level of up to 90% by weight, preferably up to 75% by weight, most preferably up to 60% by weight.

The visual signal must be easily visible in wash liquor, as well as against the bottom of the detergent formulation, so it is preferably colored. Dyes that are not fixed to the tissues at a level of 0.001 to 0.5% by weight, preferably 0.1 to 0.3% by weight of the film, can be included in the film composition.

Suitable colorants include any that are used to color liquids or detergent powders. The selected colors are yellow, blue, violet, purple, red, orange, green, pink and lilac.

Visual cues can be made by cutting or punching a film or they could be formed by cutting an extruded bar with a petal-like cross section. The manufacturing process is not critical to the invention.

The granular laundry detergent composition comprising the petal-shaped visual signal can be of any type, provided that it includes more than 5% by weight of surfactant and perfume as essential components. It is preferred that the petal contrast in color, but this is not essential if the petals are to be separated during use when floating on the surface of the wash liquor while the rest of the granules of the composition are

55 sink or disperse. Preferred surfactants are those that can be included in the petal film composition. Preferred detergency builders are phosphates and carbonates.

The granular laundry detergent compositions for use in the invention may be adjuvant or non-adjuvant, be little or very foaming and contain any type of detersive surfactant. However, it is preferred that for handwashing applications they are adjuvant, highly foaming compositions comprising anionic surfactant. Phosphate and / or carbonate detergency builders are preferred. It is especially beneficial that the powder surfactant system has synergistic compatibility with the anionic surfactant of the visual signal. Such surfactant combinations are well known in the art.

The granular composition can be manufactured by any of the known methods, such as spray drying, dry mixing and combinations thereof. It can be formed using complement granules.

It is desirable that the visual signals be dosed after the composition, preferably using a low shear mixer to ensure a homogeneous distribution of the visual signals in the granular composition. The film particles are included in the total composition in a percentage by weight in the range of 0.01 to 10% by weight, preferably 0.03 to 2% by weight, most preferably 0.1 to 1

5% by weight.

The compositions may suitably contain from 10 to 80%, preferably from 15 to 70% by weight, of detergency builder.

Preferably, the amount of detergency builder is in the range of from 15 to 50% by weight.

Often, granular detergents used for hand washing the laundry include inorganic phosphates, more especially sodium tripolyphosphate. Other possible detergency builders are orthophosphate and pyrophosphate of

15 sodium

Sodium tripolyphosphate is preferably present in an amount of from 10 to 40% by weight, more preferably from 15 to 35% by weight, most preferably from 20 to 30% by weight.

Alternative inorganic detergency builders that can be used in place of or in addition to phosphates are sodium carbonate, stratified silicates and amorphous aluminosilicates.

Alternatively or additionally, the detergent compositions of the invention may contain a crystalline alkali metal (preferably sodium) aluminosilicate (zeolite) aluminosilicate as a detergency builder. The

25 preferred zeolites with zeolite A (zeolite A4) and zeolite MAP as described and claimed in EP 384070 B.

Organic detergency builders that can be used include polycarboxylate polymers such as polyacrylates and acrylic / maleic copolymers; polyaspartates; monomeric polycarboxylates such as citrates, gluconates, oxydisuccinates, mono-, di- and trisuccinates of glycerol, carboxymethyloxysuccinates, carboxymethylximalonates, dipicolinates, hydroxyethyl iminodiacetates, alkyl and alkenyl succinates; and salts of sulfonated fatty acids.

Especially preferred organic detergency builders with citrates, properly used in

35 amounts from 5 to 30% by weight, preferably from 10 to 25% by weight; and acrylic polymers, more especially acrylic / maleic copolymers, suitably used in amounts of from 0.5 to 15% by weight, preferably from 1 to 10%.

Detergency builders, both inorganic and organic, are preferably present in the form of an alkali metal salt, especially sodium salt.

Other ingredients that are beneficially contained within a granular detergent composition include any that are conventionally used in such compositions. Especially preferred are ingredients conventionally used in hand wash compositions. Therefore, they are included

Desirably, sodium sulfate, enzymes, fluorescent agents, dye transfer inhibitors, anti-sedimentation agents, shading dyes and enzymes. Although it is possible to include bleach, this is less preferred for hand wash compositions.

The use of a green granule in the composition is advantageous if used with film colors that are associated with flowers. The effect of the visual signal due to this selection of floral colors is further amplified by the contrast of the green color of the "stem" in the granular composition. This is especially important for use with perfumes that evoke nature, such as floral perfumes.

A square petal shape and even hexagons is much preferred when the composition to which

55 adds includes perfume and, most especially, when the color of the petal shape is selected from the natural shades of lilac, pink, yellow, blue, red, etc. Consumers prefer the "petal" to a hexagon of the same size and color. Without wishing to be bound by any theory, it is believed that the greatest resemblance to the natural shape of the flower and the correlation between the shape, color and smell emanating from the powder or washing liquor, gave rise to this discovery.

The use of a visual signal that corresponds to the package is exciting for the consumer and increases the effect of the visual signal. In addition, although yellow does not function as a speck color, it can function as a visual signal due to its greater visibility against white dust, thus allowing a wider range of colors for visual cues. It may also be beneficial to add the powder to the overall effect. For example, it has been discovered that some green spots added to the powder combine with the visual signals in the form of a petal to emphasize the floral aspects. This can be further reinforced by using a range of colors.

similar in the container.

The petals may have some contrast points or a perforated area in the center to increase their resemblance to a real flower. However, it has been observed that the exact imitation of a flower is not essential. So, the

5 shapes can be smaller than a flower and can have shapes and ranges of colors somehow simplified to allow a more cost-effective manufacturing without subtracting the result of the enhanced perfume effect. This has been confirmed by testing with human subjects. Advantageously, making a hole by piercing the center of a petal also makes it lighter.

To maximize the impact of the perfume-shaped visual signal, it is desirable that the shape and smell are already related in nature, since it has been discovered that this causes the best possible response in the consumer. The color, shape and smell should be as similar as possible to natural ones. Perfumes suitable for inclusion in the composition (both in the petal and elsewhere) are described in WO 2004/11117, WO 2004/11117, WO 2004/1111 and WO 2005/059077. A perfume is not,

15 generally, a single compound, but usually a complex mixture made with a mixture of various fragrance notes. The present invention includes the use of individual compounds (fragrance notes) and complex mixtures.

The invention is particularly suitable for perfumes that are not stable at high pH or bleach. In particular, perfumes that decompose in more than 20% in aqueous solution at pH 11 for 7 days or perfumes that decompose in more than 20% when exposed to an aqueous solution containing hydrogen peroxide or 2 mM peracetic acid at pH 11 for 7 days. The percentages refer to the loss of concentration in moles per liter. The tests should be carried out at 293 K with 1 mM perfume. To solubilize perfumes, surfactants, preferably 1 g / l sodium dodecyl sulfate (SDS) can be used.

This includes compounds with a large degree of different functional groups, for example, alcohols, ketones, esters, lactones, aldehydes, terpenes and phenols.

Preferred examples of aldehyde perfumes are cyclamen aldehyde, hydroxycitronol, hydroxycinnamic aldehyde, liliol, lirol, nonadienol and phenylacetaldehyde.

Preferred examples of perfumes containing phenols are: raspberry ketone, vanillin, ethyl vanillin, 4-propyl-2-methoxyphenol, 4-allyl-2-methoxyphenol, 4-propenyl-2-methoxyphenol, hexyl salicylate, cis-3- salicylate hexenyl and methyl salicylate.

35 Perfumes are readily available to companies such as: International Flavors and Fragrances (IFF), Firmenich SA and Givaudan.

Below is a list of preferred perfumes that can be used with the present invention: alpha damascona, delta damascona; iso E super; cinnamic aldehyde; hexylcinamic aldehyde; butyl cinnamic aldehyde; benzaldehyde; anisic aldehyde; linalool; tetrahydrolinalol; undecavertol; geraniol; nerol; citronellol; citral; rose oxide; geranyl acetate; citronellyl acetate; coumarin; linalyl acetate, geranyl nitrate; citronellyl nitrile; cinnamonitrile; citronitrile; pineapple; velutone; alpha-methylionone; damascenone; gamma-terpinen; trifernal; lilial; citronelal; cyclosal; heliopropanal; zestover, aldehyde C12; tridecylenic aldehyde; cyclosia base; octenal; pulegon;

45 Vertofix® Coeur, a methyl cedril ketone from IFF; and terpinolene.

Particularly advantageously, the effects of perfume release can be obtained if the perfumes that are included in the laminar visual cues are encapsulated. An encapsulated perfume is a perfume that is mixed with a polymeric material to form a particle with a maximum dimension of 100 micrometers. Preferably, the vapor pressure of the perfume is reduced in the encapsulated particle at 293 K and 1 atmosphere (1x105 Pa) of pressure.

Typical materials used to encapsulate perfumes are modified starches, celluloses, aminoplast resins and polyacrylates. The selection of a visual signal with curvature, especially concavities similar to

55 of the convex surface of a typical granule, it is beneficial to solve the above problems. In addition, a signal that resembles a natural form, especially one with a natural perfume, is especially desirable.

As an even lighter alternative to the film, it is possible to make open felt meshes or mats of polymer-based material and cut them in the form of petals in the same manner as the films.

The petals can be colored, opaque or even partially transparent. In any case, it is possible to print on the film to provide a single color, multiple colors or a pattern such as a representation of a natural object such as a leaf or a flower.

65 A class of preferred petal shapes are those that are designed to be carved or tessellated. In order for them to be styled and still look like petals, they must have a plurality of indentations visible along their perimeter. Such concave lamellae can be expressed mathematically as for each concave lamella design it should be possible to draw a straight line that passes through the periphery of the particle at more than two points. Convex-shaped particles, such as squares, hexagons and rectangles, can never meet this requirement. Another way to express the required form mathematically is that each petal must have, or a

5 plurality of internal concave angles, or it must have a plurality of indentations due to the curved parts of its periphery.

If there are discernible internal angles, the periphery of the lamellae preferably has no internal angles of less than 100 degrees and must have at least one internal angle greater than 180 degrees (a concave angle). At least two angles of that type are preferred. Advantageously, in this case, all internal angles are less than 260 degrees, so that relatively fragile points are avoided.

Most preferred are shapes with a number of internal angles in the range of 100 to less than 180 degrees which is twice that of the range of more than 180 to less than 260 degrees.

Preferably, the shape of the petals is selected from among modified polygons so that they have at least two opposite sides endowed with a generally convex deformation extending outwards and a corresponding concave deformation extending inward, so that the deformations towards inside and out they can adjust each other by styling them.

Most preferably, the shape of the petals is selected from among modified polygons so that each side is provided with a generally convex deformation that extends outwards and a corresponding concave deformation that extends inward, so that the deformations inward and out they can adjust each other by styling them.

25 Preferred polygons are hexagons.

A preferred form for concave lamellae is based on the normal construction of a so-called Gosper Island, as this allows a single visually effective way to be used. Koch snowflakes can also be used if concave lamellae of two different sizes are desired. The Gosper Islands and Koch Snowflakes are well-known fractal concepts and have previously been used as the basis for tessellated designs or styled by mathematicians. Most preferred is a first iteration of Gosper Island, as this has 18 straight sides. This form is described in more detail below, with reference to the drawings.

It is even possible to use two completely different but complementary concave lamellae, as defined herein, to obtain the benefit of little loss attributable to the present invention.

To maximize the impact of a visual signal for perfume it is desirable that the shape of the lamellae resembles something natural and normally associated with a smell; namely, a petal, a flower, etc. Advantageously, the shape of the concave lamellae and the smell of the composition are already related in nature, since it has been discovered that this causes the best possible response in the user. More advantageously, the color of the concave lamellae adds to the signaling and the color, shape and smell should be as similar as possible to the natural ones and be related to the same smell, e.g. eg, a floral smell. The size of the concave lamellae does not seem to be as important as their shape or color. This freedom to use representations of objects smaller than

45 real as visual signals allows the use of more signals for the same surface area.

For example, the use of a 5 mm diameter visual signal with an approximate cross-sectional area of 13 mm2 allows the incorporation of the concave laminar visual signals in a casting treatment composition to deliver from 50 to 100 of such signals by wash, preferably about 70 per wash.

The natural forms that can also be used for concave lamellae that can be carved are trees, leaves and animals. An especially advantageous way to use it as a visual sign for perfume is a petal-like shape, based on a hexagon properly modified so that its design can still be styled.

55 Preferably, each side of the hexagon is modified identically. Thus, each side has both outgoing and incoming deformations that are reflections displaced from each other, the previously parallel faces of the hexagon being modified so that the new surfaces are also substantially parallel, but more complex lines. For example, the modified faces can be sinusoidal or can be formed by three interconnected lines. Preferably, the new perimeter line cuts the original perimeter of the hexagon substantially at the midpoint of one side of the original unmodified hexagon.

To facilitate manufacturing, it is preferred that most of the sides of the concave lamellae are straight, most preferably they are all straight.

65 Advantageously, all concave lamellae have substantially the same shape. They can be substantially the same size to minimize segregation problems.

Desirably, concave lamellae have rotational symmetry.

The first iteration of the preferred Gosper Islands has this symmetry.

5 The concave lamellae can be all of the same color or can comprise a mixture of different colors. The color, or colors, of the concave lamellae, can be selected to correspond to the color, or colors, of the package. The selected colors are lilac, pink, yellow, blue, red, purple, violet, green and orange.

10 The shape of the concave lamellae is directly related to an aspect of the base casting treatment composition. The shape is the shape of the outline of a flower and the composition has a floral perfume. In this case, the concave lamellae also have the color of a flower petal.

Desirably, when styled, the lamellae are arranged in rows and columns and aligned in columns and arranged in rows.

The invention will be further described below by way of example only and with reference to the accompanying drawings, of which

20 Figure 1 is a pictorial representation of a visual flower petal signal.

Figure 2 is a pictorial representation of a second visual flower petal signal, which has been tessellated.

Other embodiments of the invention will be apparent to the expert reader by following this teaching and using common general knowledge.
