Definitions
- the invention relates to a multilayer system comprising (a) a first layer and (b) a second layer, each layer comprising or consisting of a composition which comprises at least one specific perfume composition. Furthermore, the invention relates to an agent which comprises the multilayer system according to the invention. The invention also relates to a method for scenting a toilet, a multi-layer system according to the invention being used in at least one method step. A method for producing the multi-layer system according to the invention and the use of the multi-layer system according to the invention for scenting a toilet are also aspects of the invention.
- NECA Non-electrical-continuous-action or non-electrical continuous operation
- air fresheners or liquid, gel-like or solid active ingredient preparations for the toilet are formulated with a high proportion of perfume oil to spread freshness in the room or to act against bad smells.
- these air fresheners or toilet additive products are formulated with a single perfume composition.
- air fresheners or toilet additives, or their perfume compositions are usually formulated in such a way that they should always deliver the same intensity and the same scent impression for weeks after activation.
- Both NECAs and other technical systems are equipped in such a way that a complete "perfume composition" of top, heart and base notes is emitted and perceived in the room.
- FMCGs fast-moving consumer goods
- the individual components of a classically composed perfume evaporate at different speeds.
- the chronological sequence in the perception of a perfume scent is referred to as progression.
- the course is divided into fragrance notes, which usually flow into one another.
- Perfumes usually contain all three notes.
- the top note of a perfume is responsible for the 'first impression' that a perfume conveys.
- the top note typically consists of intense, light, rapidly evaporating fragrances with a maximum perception duration of several minutes.
- the heart note is the scent that is noticeable when the top notes have dissipated.
- the heart note of a perfume is responsible for the actual fragrance character of a perfume.
- the heart note consists of fragrances with a maximum perception duration of several hours.
- the base note is the last scent to be perceived. It typically contains long-lasting, heavy fragrances that can linger for days.
- toilets Due to high variances in the processing of ceramic materials, toilets show a high diversity in water flushing behavior. Nevertheless, toilet additive products show through the conversion / or. Rinsing water usually overflows an olfactory delta, ie a perception lift in the Intensity of Perfuming. This is due to the detachment or dissolution of the soap-like or gel-like active ingredient preparation, in which form these toilet additive products are usually formulated, or to turbulence and air movements which are generated by the flushing water in the toilet.
- these perfumes are composed as usual for NECA air fresheners. In this case, fragrances are used which are released into the ambient air well to very well at room temperature.
- each layer preferably containing a different perfume composition, preferably air fresheners or toilet additive products, in particular liquid or gel-form toilet fragrance rinsers
- the individual layers are preferably in liquid or gel form.
- an olfactory delta arises, i.e. the perception of the intensity and the scent impression/scent progression, which is achieved over the entire life cycle of the toilet additive product, changes change once or several times over the period of use. In the context of this invention, this change is also referred to as a perception lift.
- the invention relates to a multi-layer system comprising
- Perfume composition includes, wherein the perfume composition
- Perfume composition includes, wherein the perfume composition
- the multilayer system comprises
- the first layer and/or the second layer of the multilayer system are particularly preferably liquid or gel-like at room temperature (20° C.; and at standard pressure (1 bar)).
- the first and second layers are directly adjacent, i.e., directly adjoin at least one face.
- the first layer overlies or underlies the second layer.
- the layers are water-soluble or water-dispersible, i.e. they dissolve or the components disperse on contact with water. This property refers to the behavior under standard conditions, i.e. at room temperature (20°C) and normal pressure (1 bar).
- the first and second and optionally also each additional layer are arranged in such a way that they only come into contact with the environment, and here in particular with water, one after the other. This is typically done in such a way that the layers are arranged one on top of the other in a container, so that only the top layer comes into contact with the environment, for example the room air or rinsing water, and only when the top layer gradually dissolves or disperses in the rinsing water or has dissolved, the next underlying layer comes into contact with the environment, usually the rinsing water.
- This successive dissolution of the various layers lying one on top of the other can therefore bring about a changed scent impression.
- the changed scent impression is brought about by the different perfume compositions contained in the respective layers.
- the invention relates to an agent comprising the multi-layer system according to the invention.
- the multi-layer system can also be such a means.
- agents are toilet cleaners or toilet blocks, especially those in gel form.
- a further aspect of the invention is a method for scenting a toilet, the multilayer system according to the invention or the agent according to the invention being used in at least one method step. It is particularly preferred here that the scent impression changes over time.
- the invention relates to a method for producing the multilayer system according to the invention.
- the composition of the first layer and/or the second layer is preferably melted at at least 50° C. and then cast in layer form.
- the invention relates to the use of the multilayer system according to the invention or the agent according to the invention for scenting a toilet, with the scent impression preferably changing over time.
- At least one includes but is not limited to 1, 2, 3, 4, 5, 6 and more.
- the information refers to the type of ingredient and not to the absolute number of molecules.
- At least one fragrance thus means, for example, at least one type of fragrance, i.e. one type of fragrance or a mixture of several different fragrances can be meant.
- the information refers to all compounds of the type specified that are contained in the composition/mixture, i.e. the composition does not contain any other compounds of this type beyond the specified amount of the corresponding compounds.
- the multi-layer system described in more detail below is characterized in that it comprises at least a first and a second layer, wherein
- the first layer comprises or consists of a composition comprising at least one perfume composition, wherein the perfume composition
- the second layer comprises or consists of a composition comprising at least one perfume composition, wherein the perfume composition
- the perfume composition of the first layer and that of the second layer are different, preferably so different that they bring about a distinctly different scent impression.
- fragrance composition refers to mixtures of two or more fragrance compounds, and thus covers, for example, synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type, as well as natural fragrance mixtures such as those from plant sources are accessible.
- odorant/perfume Most people perceive the smell of an odorant/perfume as pleasant and often corresponds to the smell of, for example, blossoms, fruits, spices, bark, resin, leaves, grasses, mosses and roots. Fragrances/perfumes can also be used to mask unpleasant smells or to provide a non-smelling substance with a desired smell.
- Vapor pressure at 25°C ⁇ 0.000133kPa.
- the vapor pressure is determined, for example, using the commercially available program EPI-Suite 4.11 (MPBPWIN v1.43 (modified grain method). Unless stated otherwise, the values given here were calculated using this program.
- the ClogP value of the fragrance which is a measure of the hydrophilicity of a compound, is a decisive factor for scent perception, since certain fragrances are rinsed off at different rates depending on the ClogP value, and the multisensory effect thus continues is strengthened.
- fragrances with ClogP values of less than or equal to 2.5 are rinsed off more quickly and distributed better in the room than, for example, fragrances with a ClogP of greater than or equal to 4.
- the ClogP value is the n-octanol-water partition coefficient of a chemical compound and can be each chemical compound can be calculated.
- Suitable programs for carrying out such a calculation or lists with corresponding ClogP values are known in the prior art and are readily available to the person skilled in the art.
