Description

CLEANING AND CONDITIONING SINGLE PRODUCT FOR PERSONAL HYGIENE, METHOD OF MANUFACTURE AND USE

TECHNICAL FIELD

The present invention relates to a considerably dry, personal care cleanser, disposable cleanser and conditioner for conditioning skin or hair. These products are used by the consumer by soaking the dry product in water. The article comprises a water-insoluble substrate, a foamed detergent and a conditioning component having a lipid hardness of at least 0.02 kg. The use of a substrate at low detergent levels improves foaming, enhances cleaning and peeling, and optimizes delivery and deposition of conditioning ingredients. The result of the present invention provides efficient cleaning using low levels of detergent and therefore less irritation, while providing excellent conditioning benefits.

The invention also includes products comprising a variety of active ingredients delivered to the skin or hair.

The invention also includes a method of continuously applying conditioning agents to the skin or hair.

The invention also includes a method of cleansing and moisturizing the skin or hair using the compositions of the present invention, as well as a method of making the compositions.

BACKGROUND OF THE INVENTION v

Personal hygiene cleaners are traditionally sold in various forms, such as soaps, creams, lotions and gels. These forms of cleaning agents attempt to satisfy a number of criteria to make them acceptable to consumers. These criteria include cleansing efficiency, skin feel, mildness to the skin, hair and mucous membranes, and foam volume. An ideal personal hygiene cleaner should gently cleanse the skin or hair, cause little or no irritation, and leave the skin or hair too dry after frequent use.

However, these traditional forms of personal care cleaners have the inherent problem of balancing cleaning performance over delivery and conditioning. One solution to this problem is to use the cleaning and conditioning agent separately. However, this is not always a convenient or practical solution, and many consumers have preferred to use one product that has the ability to both cleanse and condition the skin or hair. In a conventional detergent, the conditioning ingredients are different because many of the conditioners are incompatible with detergents and the result is undesirable • · ·· ···

inhomogeneous mixture. In order to achieve a homogeneous composition with conditioning ingredients and to protect against loss of conditioning ingredients prior to application, other ingredients, such as emulsifiers, thickeners and gelling agents, are often added to suspend the conditioning ingredients in the detergent composition. This leads to an aesthetically pleasing homogeneous mixture, but often it leads to insufficient application of the conditioning components, since the conditioners are emulsified and inefficiently released during cleaning. Many conditioning agents also have the disadvantage of suppressing the formation of foam. Suppression of foaming is a problem since many consumers are looking for cleansing products that provide rich, creamy and abundant foam.

Therefore, conventional detergent compositions that attempt to combine detergents and conditioning ingredients appear to suffer from the disadvantage inherent in incompatibility of detergents and conditioning agents. There is a clear need for the development of cleaning systems that effectively clean and yet consistently provide sufficient conditioning in a single product.

It is also highly desirable to successfully clean and condition the disposable composition. Disposable formulations are suitable as they avoid the need to be in cumbersome bottles, soap pieces, jars, tubes and other forms of both cleansing and conditioning agents. Disposable formulations are also a more hygienic alternative to the use of a sponge, dishwashing detergent or other multiple-use cleaners, as they cause bacterial growth, unpleasant odor and other unwanted reusable things. Surprisingly, it has been found in the present invention that the articles can be developed for efficient cleaning and thorough conditioning and will be suitable, inexpensive, and disposable hygiene products for personal hygiene. The present invention provides a suitable composition which is not separately cleansing and conditioning. The product of the present invention is most suitable for use as it is in the form of a substantially dry composition which is soaked before use.

Furthermore, it has been found that the consumer is accustomed to the fact that disposable products have two significantly different surfaces. Foaming is achieved by scrubbing the surfaces of the article against or against other surfaces of each other according to the method of use. If the surface contains conditioning agents is used to form a foam and the same surface is used in contact with skin and hair, the distribution of conditioning agents is greatly reduced through emulsifying the conditioning agents with a detergent. If, however, the non-conditioning agent surface (e.g., the detergent-containing surface) is scrubbed to form a foam and the conditioning agent surface is used subsequently in contact with the skin and hair, the maximum distribution of the conditioning agents is achieved. If both surfaces of the article are treated with conditioning agents, inconsistent separation may occur. The maximum distribution of conditioning agents can only be achieved if the foaming-free surface is ingested in contact with the skin or hair.

Surprisingly, it has been found that if the conditioning component (combination of conditioning agents) has a minimum lipid hardness of 0.02 kg, the unevenness in the distribution of the conditioning agents is greatly reduced. It is believed that increasing the hardness of the conditioning component will reduce the transfer in the substrate and also reduce the emulsification of the conditioning agents by detergents during the foaming step.

As a result, more conditioning agents remain available for mechanical transmission upon contact with skin or hair.

The present invention relates to a dry, disposable, personal cleansing product useful for cleaning and conditioning the skin or hair. These products are used by customers by soaking a dry product in water. The product comprises a water-insoluble substrate, detergents and a conditioning component having a lipid hardness of at least 0.02 kg. Without being limited by theory, it is believed that the substrate increases foaming at low detergent content, increases cleaning and washing, and optimizes the delivery and distribution of conditioning agents. It is also believed that a lipid hardness of at least 0.02 kg provides greater efficacy and an even distribution of skin and hair conditioning agents. As a result, the invention provides efficient cleaning using low, and therefore less irritating, detergent concentrations while providing great conditioning benefits in distribution and efficacy. It has also been found that these products are useful for applying a wide range of active agents to the skin or hair during the cleansing process.

It is therefore an object of the present invention to provide substantially dry products for cleaning and conditioning the skin or hair where the products are used in combination with water.

This is another object of the present invention to provide articles comprising a water-insoluble substrate, a detergent and a conditioning component having a lipid hardness of at least 0.02 kg.

This is another object of the present invention to provide products for single use only. This is another object of the present invention to provide products that are gentle to the skin and hair. This is another object of the present invention to provide products useful for bringing the active agents to the skin or hair during the cleansing and conditioning process.

This is another object of the present invention to provide methods for cleansing and conditioning the skin and hair.

This is another object of the present invention to provide methods that evenly distribute the conditioning agents.

This is another object of the present invention to provide methods of making the articles of the present invention.

These and other objects of the invention will become apparent from the following description.

SUMMARY OF THE INVENTION

The present invention relates to a disposable personal care cleansing composition for cleaning and conditioning comprising: (A) a water-insoluble substrate, (B) at least one foamed detergent added to or impregnated thereon, and (C) a conditioning component added to substrate or impregnated thereon. The conditioning component has a lipid hardness value greater than 0.02 kg and the composition is considerably dry before use.

In other cases, the present invention relates to a personal care cleanser, disposable for cleaning and conditioning comprising:

(A) a water-insoluble substrate; and (B) a cleaning and conditioning component added to or impregnated with said substrate, comprising:

(i) at least one foam detergent; and (ii) a conditioning component having a lipid hardness greater than 0.02 kg.

In such cases, the foamed detergent and conditioning component are added separately or concurrently to or impregnated with the water-insoluble substrate and the weight ratio of the foamed detergent and conditioning component is less than 20: 1. In such cases, the composition is also considerably dry before use.

In other instances, the present invention relates to a method of making a personal care cleansing composition, a disposable use for cleaning and conditioning, comprising the step of separately or simultaneously adding to or impregnating a water-insoluble substrate:

(A) at least one foamed detergent; and (B) a conditioning component having a lipid hardness greater than 0.02 kg.

The weight ratio of the foamed detergent to the conditioning component is less than 20: 1. The resulting composition is considerably dry.

In another case, the present invention relates to a method of cleansing and conditioning the skin or hair with the personal care cleansing composition described herein.

In other cases, the present invention relates to a method of uniformly applying conditioning agents to the skin or hair.

All percentages and ratios used herein, unless otherwise indicated, are by weight and all measurements are made at 25 ° C unless otherwise indicated. The invention may also comprise, consist or mainly consist of the necessary additional ingredients and components described herein.

The personal cleansing compositions of the present invention are highly effective for cleansing the skin or hair, further providing an effective distribution of conditioning agents. The product may also contain other non-condensing active formulations that are applied to the skin or hair.

Without being limited by theory, it is believed that the substrate contributes significantly to the generation of soap suds and the distribution of conditioning agents and any other active ingredients. This increase in soap suds and distribution is believed to be the result of the surface effect of the substrate. As a result, less and less surfactants can be used.

A reduced amount of the desired detergent is believed to be related to a decrease in the drying effect on the skin or hair caused by the detergent. In addition, a reduced amount of detergent will substantially reduce the inhibitory effect (eg, by emulsification or direct removal with a detergent) of the detergents on the conditioning agent distribution.

Without being limited by theory, the substrate also increases the distribution of conditioning agents and active ingredients. As long as the invention is in dry form, it does not require an emulsifying agent that can inhibit the distribution of conditioning agents and active ingredients. Moreover, since the skin conditioners and active ingredients are dried on or filled with the substrate, they are directly transferred to the skin or hair by surface contact of the wet composition with the skin.

Finally, the substrate also increases the cleaning effect. The substrate may have different properties on each side, e.g., rough side and smooth side. The substrate acts as an effective foaming and peeling tool. Using physical contact with skin or hair, the substrate helps significantly in cleaning and removing dirt, makeup, dead skin and other impurities.

It is believed that a minimum lipid hardness value of 0.02 kg for conditioning ingredients provides an even distribution of conditioning agents to the skin or hair as the transfer in the substrate decreases, and also by reducing the emulsification of the conditioning agents by detergents during the soap sudsing step.

By "foaming detergent" is meant a detergent which, when mixed with water and mechanically processed, forms a foam or a soapy foam. Preferably, these detergents should be weak, which means that these detergents provide sufficient washing or cleaning performance but do not dry the skin or hair very much and still meet the foam formation criteria set forth above.

The terms "disposable" or "disposable" are used in their ordinary sense to refer to a product that is discarded or disposed of after a single use.

The term "conditioning component" as used herein means a combination of conditioning agents.

The term "water activated" as used herein means that the present invention is prepared for the consumer in dry form and used after soaking in water. These products have been found to produce soap suds or are "activated" upon contact with water and subsequent processing.

As used herein, the term "substantially dry" means that the product is substantially water-free prior to use and generally appears dry to the touch. The products of the present invention contain less than about 10% by weight of water, preferably less than 5% by weight of water, even more preferably less than 1% by weight of water, assuming measurements in a dry environment, e.g. low humidity. One of ordinary skill in the art would recognize that the water content of an article such as the present invention may vary with the relative humidity of the environment.

The term "weak" as used herein in reference to foaming detergents and products of the present invention means that the products of the present invention exhibit skin softness comparable to a fine synthetic rod based on an alkyl glyceryl ether sulfonate (AGS) detergent. Methods for measuring the fineness or irritation of a detergent-containing product are based on a skin barrier damage test. In this test, the detergent that is less damaging to the skin barrier is finer. Skin barrier damage is measured by the relative amount of radiolabeled water (3H-H2O) that passes from the test solution through the skin to the physiological buffer contained in the diffusion chamber. This test is described in T. J. Franz: J. Invest. Dermatol., 1975, 64, 190-195, and in U.S. Pat. No. 4,673,525, Smali et al., issued June 16, 1987, which are incorporated herein by reference in their entirety. Other test methods for determining the fineness of the detergent, well known to those skilled in the art, can also be used.

The term "uniform distribution" as used herein means the distribution of the conditioning agents containing the conditioning component will be relatively independent of the manner in which the customer prepares and uses the detergent and conditioning composition (eg foaming the side of the substrate carrying the conditioning component against the foaming side of the detergent). The products of the present invention will have a uniformity of distribution of greater than 60%, preferably greater than 65%, even more preferably greater than 70%, preferably greater than 75%. Measurement of uniformity of distribution is the quotient obtained by dividing the amount of split conditioning agents that occur as "non-ideal foam and use" by the amount of split conditioning agents that occur as "ideal foam and use". Non-ideal foaming, as used herein, means that foaming is achieved by scrubbing itself or other surface of the conditioning product and then contacting the skin or hair with the same surface. This causes ineffective distribution of the conditioning agents, since some of the conditioning agents become emulsified by the detergent. Ideal foaming, as used herein, means that foaming is achieved by scrubbing itself or another surface of a detergent-containing product but not containing conditioning agents, followed by contact of the skin or hair with the surface containing the conditioning component. The same reference point will be applied if both surfaces of the substrate react with conditioning agents (eg the division obtained from foaming and skin contact with the same

494 00 409 04 04 foamed surface containing emulsified skin conditioning agents against the non-foamed surface containing non-emulsified conditioning agents). The uniformity of distribution is maximal when the lipid hardness value is greater than about 0.02 kg.

The personal care products of the present invention comprise the following essential ingredients. A component that is either incorporated into or applied to the substrate necessarily contains one or more foaming detergents and one or more conditioning agents. Other active ingredients may also be included in the composition. Another preferred method is to apply each additive separately to the substrate.

Water insoluble substrate

The products of the present invention comprise a water-insoluble substrate. By " water insoluble " is meant that the substrate does not dissolve, or the sky is immediately separated when immersed in water. The water-insoluble substrate is a tool or means for delivering foaming detergents and a conditioning component of the present invention to skin or hair that is washed and conditioned. Without being limited by theory, it is believed that the substrate, by providing mechanical forces and processing, provides a foaming effect and also assists in the distribution of the conditioning component.

A wide variety of substances can be used as a substrate. The following non-limiting characteristics are desirable: (i) sufficient wetting force in use, (ii) sufficient roughness, (iii) sufficient flexibility and porosity, (iv) sufficient thickness and (v) appropriate size.

Non-limiting examples of suitable insoluble substrates that meet the above criteria include nonwoven substrates, woven substrates, water-entangled substrates, air-entangled substrates, natural sponges, synthetic sponges, polymeric cross-linking webs, etc. Preferred embodiments include nonwoven substrates because they are economically and readily available in a wide range of materials. By the term nonwoven is meant that the layer is composed of fibers that are not woven into the fiber, but are preferably formed into a sheet, tuft or cushion. The fibers may be either random (i.e., randomly aligned) or combed (i.e., combed in one main direction). In addition, the nonwoven substrates may be composed of a combination of layers of combed and random fibers.

The nonwoven substrates may be comprised of a wide variety of materials, both natural and synthetic. The term natural means that the materials are derived from plants, animals, insects or are by-products of plants, animals and insects. By synthetic it is meant that the materials are obtained primarily from various synthetically prepared materials or from natural materials that have been further altered. The conventional base material is usually a fibrous web containing any ordinary synthetic or natural textile fibers, or a mixture thereof.

Alternatively, the water-insoluble substrates may be polymeric cross-linked sponges as disclosed in European patent EP 702550 A1 published March 27, 1996, incorporated herein by reference. The polymer sponges contain a plurality of extruded tubular netting layers prepared from a highly flexible polymer, such as olefin monomer addition polymers and polycarboxylic acid polyamides. Although these polymer sponges are prepared after use in conjunction with liquid detergent compositions, these types of sponges can be used as water-insoluble substrates in the present invention.

The substrate can be made in a wide variety of shapes and forms, including flat pads, thick pads, thin sheets, spherical tools, irregularly shaped tools, and has a surface area of from about square inches to about hundreds of square inches. The exact size will depend on the intended use and properties of the product. Particularly suitable are square, round, rectangular or oval pads having a surface area of from 1 square inch to 144 square inches, preferably from 10 square inches to 120 square inches of surface, more preferably from 30 square inches to 80 square inches, and a thickness of from 1 thousandth of an inch to 500 thousandth of an inch, preferably from 5 thousandths of an inch to 250 thousandths of an inch, more preferably from 10 thousandths of an inch to 100 thousandths of an inch.

The water-insoluble substrates of the present invention may comprise two or more layers, each having a different structure and roughness. Different structures may arise from the use of different combinations of materials or from the use of a different manufacturing process, or combinations thereof. Dual structural substrates can be manufactured to provide the benefit of a more rough side for rough washing and a softer, absorbent side for gentle washing. In addition, the separate substrate layers may be made to have a different color, thereby helping the user to further recognize the surface.

The conditioning component of the present invention may also contain a conditioning emulsion that is used to improve conditioning of the skin or hair during use of the composition. By "conditioning emulsion" as used herein is meant a combination of an inner phase comprising a water-soluble conditioning agent surrounded by an outer phase comprising an oil-soluble agent. In preferred cases, the conditioning emulsion could further comprise an emulsifier. The conditioning emulsion comprises from 0.25% to 150%, preferably from 0.5% to 100%, and most preferably from 1% to 50% by weight of said water-insoluble substrate. By conditioning emulsion is meant a combination of an inner phase comprising a water-soluble conditioning agent surrounded by an outer phase comprising an oil-soluble agent. If appropriate, the conditioning emulsion could further comprise an emulsifier.

The conditioning emulsion comprises (i) an inner phase comprising the water-soluble conditioning agents described above and (ii) an outer phase comprising the oil-soluble agents described above. In other cases, the conditioning emulsion comprises an emulsifier capable of forming an emulsion of said internal and external phases. Although such an emulsifier is suitable for the present invention, it can be concluded in the skin care industry that the water-soluble conditioning agent may be surrounded by an oil-soluble emulsifier-free agent. As long as the water-soluble conditioning agent is surrounded by an oil-soluble agent is protected against washing during the cleaning process, the composition should be within the scope of the present invention.

The inner phase may further comprise other water-soluble or dispersed materials that do not adversely affect the stability of the conditioning emulsion. One such material is a water-soluble electrolyte. The dissolved electrolyte reduces the tendency of the materials present in the lipid layer to dissolve in the aqueous phase. Any electrolyte capable of supplying ionic strength to the internal phase can be used. Suitable electrolytes include water-soluble mono-, di- or trivalent inorganic salts, eg, water-soluble halides, eg, chlorides, nitrates and sulfates of alkali metals and alkaline earth salts. Examples of such electrolytes are sodium chloride, calcium chloride, sodium sulfate, magnesium sulfate and sodium carbonate. The electrolyte will normally be included in a concentration range of 1 to 20% of the internal phase.

Other water-soluble or dispersed materials present in the internal phase include thickeners and viscosity modifiers. Suitable thickeners and viscosity modifiers include water-soluble polyacrylic and hydrophobically modified polyacrylic resins,

These thickeners and viscosity modifiers will normally be included in the concentration range from 0.05 to 0.5% of the internal phase.

Other water-soluble or dispersed materials that are present in the internal phase include polycationic polymers providing steric water-lipid stability and nonionic polymers that also stabilize water in the lipid emulsion. Suitable polycationic polymers include Reten 201, Kymene 557H® and Acco 7112. Suitable nonionic polymers include polyethylene glycols (PEG), e.g., Carbowax. These polycationic and nonionic polymers will normally be present in a concentration range of from 0.1 to 1% of the internal phase.

Suitable examples of the present invention, which consist of conditioning emulsions, include emulsifiers capable of forming an emulsion of internal and external phases. In the emulsions of the present invention, the emulsifier is contained in an effective amount. What constitutes an "effective amount" will depend on a number of factors including the appropriate amount of oil-soluble agents, the type of emulsifier used, the level of impurities present in the emulsifier, etc. Typically, the emulsifier comprises from 0.1% to 20%, preferably from 1% to 10%; preferably from 3% to 6% by weight of the conditioning emulsion.

Lipid hardness value

The conditioning component of the present invention will have a minimum lipid hardness value of about 0.02 kg. The lipid hardness value is the physically measured hardness of the combination of all conditioning agents with the conditioning component. Increasing the lipid hardness value appears to increase the application density of the conditioning agent, although the consumer uses a variety of foaming techniques. Increasing lipid hardness appears to decrease substrate transfer as well as • 9 ·

During foaming, it reduces the dispersal of the conditioning agents by detergents. As a result, many conditioning agents are available for mechanical transmission by skin or hair contact. The conditioning component of the present invention has a lipid hardness value greater than 0.02 kg, preferably greater than 0.05, and most preferably greater than 0.01. Suitably, the hardness value of the conditioner lipid should not be greater than 5.00 kg, preferably not more than 4 kg, preferably not more than 3 kg, as hardness values above this value may negatively affect the application of conditioning agents in the conditioning component to the skin or hair.

Lipid Hardness Test

The lipid hardness value was measured by a test commonly used to measure the hardness of a piece of soap, the Chatillon meter is used to measure a hardness of 5-8 oz. (ounces) of conditioning agent sample. To obtain an average value, several values are needed for each fresh sample, the Chatillon Model No. DFIS100 is manufactured by Chatillon, which is in Graysboro, South Carolina.

For example, the foaming detergent may first be added to the water-insoluble substrate or soaked after the conditioning agents or vice versa. Alternatively, the foaming detergent and conditioning agent may be added to or impregnated on the water-insoluble substrate. Alternatively, the foaming detergent and conditioning agents may be mixed together before being added to or impregnated with the water-insoluble substrate.

Detergent, conditioning agents, and any other ingredients may be added to or impregnated with the water-insoluble substrate in a manner well known in the art: e.g., spray, laser printing, spraying, wetting, or coating.

When water or moisture is used or present in the production process, the resulting treated substrate is then dried to be substantially dry. The treated substrate may be dried by any method known in the art. Non-limiting examples of known drying methods include the use of drying in an oven, radiant heating, microwave oven, hot air oven and a heating cylinder or in a drying drum.

Drying also includes air drying without the addition of thermal energy other than that present in the surroundings. A combination of different drying methods may also be used.

Methods of cleansing and conditioning the skin or hair

The present invention relates to a method of cleansing and conditioning the skin or hair with a personal care cleansing composition of the present invention. The methods comprise the steps of wetting a disposable personal cleansing water composition for personal hygiene comprising a water-insoluble substrate, a foaming detergent and a conditioning component, and contacting the skin or hair with the soaked product. In other cases, the present invention is also useful for delivering a variety of active ingredients to the skin or hair.

The compositions of the present invention are substantially dry and are intended to be soaked in water prior to use. The product is soaked by immersion in water or placed under running water. The foam is formed by mechanically agitating or deforming the composition either before or during contact of the composition with skin or hair. The resulting foam is useful for cleansing and conditioning the skin or hair. During the cleaning process and subsequent rinsing with water, the conditioning agents and active ingredients are applied to the skin or hair. The application of conditioning agents and active ingredients is increased by physical contact of the substrate with the skin or hair.

These active ingredients are also useful for the thorough application of the active ingredients to the skin or hair.

The compositions of the present invention have a coating density of greater than 60%, suitably greater than 65%, more preferably greater than 70% and most preferably greater than 75%.

Density measurement is the fraction obtained by dividing the deposition of conditioning agents in "non-ideal foaming and use" by deposition of the conditioning agents in "ideal foaming and use". By non-ideal foaming as used herein is meant that foaming is achieved by rubbing the surface of the conditioning agent product and then contacting the same surface with the skin or hair. This causes ineffective deposition of conditioning agents, since detergents emulsify some conditioning agents. By the ideal foaming as used herein is meant that foaming is achieved by rubbing the surface of the conditioner-free product and then contacting the skin or hair with the surface containing the conditioner. The same point could be applied if both surfaces of the substrate are treated with conditioning agents (eg, a coating obtained by foaming or contacting the skin with the same foaming surface containing emulsified conditioning agents against contacting the skin with a non-foaming surface containing the non-emulsified conditioning agent). The deposition density is maximum when the lipid hardness value is greater than 0.02 kg.

Determination of the amount of conditioning component applied to the skin or hair can be measured by various standard analytical methods well known to those skilled in the chemical arts, including, for example, extraction of the skin or hair area with suitable solvents and subsequent chromatographic analysis (ie gas chromatography, liquid chromatography, supercritical direct spectroscopy may be performed on the skin or hair by IR spectroscopy, UV / VIS spectroscopy, opacity measurement, fluorescence spectroscopy, ESCA spectroscopy, and the like.

By conventional methods for measuring deposition, the product of the present invention is soaked in water and rubbed and mixed to form a foam. The product is then rubbed for about 15 seconds in an area of about 25 cm ² to 300 cm ² , preferably 50 cm ² to 100 cm ^{2 of the} skin or head, which has been delimited by the use of an appropriate indelible marker. The surface was then washed for approximately 10 seconds and then air dried for 10 minutes. The area was then either extracted and the extract analyzed or analyzed directly using the methods previously exemplified.
