BACKGROUND Human hair becomes soiled due to its contact with the surrounding environment and from the sebum secreted by the scalp. The soiling of hair causes it to have a dirty feel and an unattractive appearance. The soiling of the hair necessitates shampooing with frequent regularity.

Shampooing cleans the hair by removing excess soil and sebum.

However, shampooing can leave the hair in a wet, tangled, and generally unmanageable state. Once the hair dries, it is often left in a dry, rough, lusterless, or frizzy condition due to removal of the hair's natural oils and other natural conditioning and moisturizing components.

Frizzy condition of the hair often causes an expanded and unruly hair and makes it difficult to control the hair style. For consumers who desire well aligned hair, such expanded and unruly hair is not desirable. The term"frizz control" herein means to control hair frizz, i. e., to reduce frizz condition of the hair or to prevent the hair from causing frizzy condition.

A variety of approaches have been developed to condition the hair, for example, to control hair frizz. These approaches range from post-shampoo application of hair conditioners such as leave-on and rinse-off products, to hair conditioning shampoos which attempt to both clean and condition the hair from a single product.

Although some consumers prefer the ease and convenience of a shampoo which includes conditioners, a substantial proportion of consumers prefer the more conventional conditioner formulations which are applied to the hair as a separate step from shampooing, usually subsequent to shampooing. Conditioning formulations can be in the form of rinse-off products or leave-on

products, and can be in the form of an emulsion, cream, gel, spray, and mousse.

Such consumers who prefer the conventional conditioner formulations value the relatively higher conditioning effect, or convenience of changing the amount of conditioning depending on the condition of hair or amount of hair.

Commonly, hair conditioning benefits are provided through the use of hair conditioning agents such as cationic surfactants, cationic polymers, silicone conditioning agents, hydrocarbon and other organic oils and solid aliphatics such as fatty alcohols. However, such conditioning agents are often impractical for using in the large amounts necessary to control hair frizz. Usage of large amounts of conditioning agents that work to control hair frizz by coating and weighing down the hair commonly results in a poor perception of hair cleanliness and hair feel, for example, leaving the hair and hands with a tacky, dirty, feeling.

Thus, there is a desire for a hair conditioning product which provides improved frizz control benefit in addition to other conditioning benefits such as smoothness, softness, and reduction of friction, while reducing sticky and greasy feeling.

In addition to such a desire for hair conditioning products, there also is a desire for a hair product that provides hair styling benefits, especially hair style achievement, and hold and retention. Such style retention is generally accomplished by temporary alteration of hair style/shape. A temporary alteration is one which can be removed by water or by shampooing. Temporary style alteration has generally been accomplished by means of the application of a separate composition or compositions from shampoo and/or conditioning compositions. The materials used to provide setting benefits have generally been resins or gums and have been applied in the form of leave-on products such as mousses, gels, waxes, creams, lotions, or sprays. Since the style hold is provided by resin materials which set-up on the hair, the hair tends to feel sticky or stiff after application. Thus, there is a desire for hair styling products having reduced sticky and stiff feeling.

Further, for consumers who desire both conditioning benefits and styling benefits, there is a desire for obtaining the two separate hair care benefits, i. e., conditioning and styling benefits, from a single hair care product.

However, conventional hair styling conditioner products are not completely satisfactory in providing styling benefits such as hair style achievement, and hold and retention, while delivering improved conditioning benefits such as smoothness, softness, and reduction of friction.

Furthermore, some hair styling conditioning products may have lower stability due to the compatibility between styling polymers and conditioning agents.

Based on the foregoing, there remains a desire for hair styling conditioner products which provide two separate hair care benefits, i. e., conditioning and styling benefits, from a single hair care product.

Furthermore, there remains a desire for hair styling conditioning products which have better stability.

Furthermore, there remains a desire for hair styling conditioning products which provide hair styling benefits such as hair style achievement, hold, and retention.

None of the existing art provides all of the advantages and benefits of the present invention.

SUMMARY The. present invention is directed to a hair care kit comprising: a hair styling composition comprising a styling polymer ; and a hair conditioning composition comprising a conditioning agent; wherein the hair styling composition is isolated from the hair conditioning composition.

These and other features, aspects, and advantages of the present invention will become evident to those skilled in the art from a reading of the present disclosure.

The hair care kit of the present invention can provide two separate hair care benefits, i. e., conditioning and styling benefits, from a single hair care product.

The present invention provides hair care kits which are used for applying a mixture of a hair styling composition and a hair conditioning composition to the hair, the compositions being isolated in the kits prior to use.

It has been found that; when a hair conditioning composition and a hair styling composition are applied to the hair separately in a subsequent manner, well-balanced conditioning and styling benefits can not be obtained. It has been found that; depending on the order of the application, either hair conditioning compositions or hair styling compositions prevent the other from providing satisfactory benefits.

However, it has been surprisingly found that; the mixture of a hair styling composition and a hair conditioning composition mixed immediately before application to the hair can provide well-balanced conditioning and styling benefits.

Furthermore, since the hair styling composition is isolated from the hair conditioning composition in the kit prior to use, the compositions comprised in the kit of the present invention have an improved stability compared to hair styling conditioning compositions containing both styling polymers and conditioning agents.

In one embodiment, the hair care kits of the present invention can further provide improved frizz control benefit in addition to other conditioning benefits.

Such embodiment. comprises hair conditioning compositions containing at least one material selected from the group consisting of: (i) silicone compounds which have a molecular weight of from about 100,000 to about 1,500,000 and have a viscosity of from about 500,000 to about 50,000, OOOmPa-s ; (ii) frizz control agents; and (iii) mixtures thereof.

In another embodiment, the hair care kits of the present invention can further provide good hair feel and appearance, i. e., provide reduced sticky, greasy, and stiff feeling. Such embodiment comprises hair conditioning compositions containing at least one material selected from the group consisting of: (i) volatile compounds; (ii) thickening agent comprising carboxylic acid/ carboxylate copolymer ; (iii) thickening system comprising at least 2 thickening agents selected from the group consisting of a hydrophobically modified cellulose ether, an acrylates copolymer, and a crosslinked polymer ; (iv) a hydrophobically modified cellulose ether thickener; and (v) mixtures thereof.

Non-volatile polysiloxane resin Polysiloxane resins useful herein are highly crosslinked polymeric siloxane systems. The crosslinking is introduced through the incorporation of trifunctional and tetrafunctional silanes with monofunctional or difunctional, or both, silanes during manufacture of the silicone resin. As is well understood in the art, the degree of crosslinking that is required in order to result in a silicone resin will vary according to the specific silane units incorporated into the silicone resin. In general, silicone materials which have a sufficient level of trifunctional and tetrafunctional siloxane monomer units (and hence, a sufficient level of crosslinking) such that they dry down to a rigid, or hard, film are considered to be silicone resins. The ratio of oxygen atoms to silicon atoms is indicative of the level of crosslinking in a particular silicone material. Silicone materials which have at least about 1.1 oxygen atoms per silicon atom will generally be silicone resins herein. Preferably, the ratio of oxygen atoms to silicon atoms is at least about 1.2: 1.0.

As used herein, the term "polypropylene glycol"includes single-polypropylene glycol-chain segment polymers, and multi-polypropylene glycol-chain segment polymers. The general structure of branched polymers such as the multi-polypropylene glycol-chain segment polymers herein are described, for example, in"Principles of Polymerization,"pp. 17-19, G.

Method of Preparation The hair conditioning compositions as shown above can be prepared by any conventional method well known in the art.

For example, the hair conditioning compositions of Cond. 1-5 are suitably made as follows : The polymeric materials such as the thickening agents, amphoteric conditioning polymers, and cationic conditioning polymers, if present, are dispersed in water at room temperature, and mixed by vigorous agitation.

The frizz control agents, if present, are added to the mixture, and mixed by vigorous agitation until fully dispersed. The non-volatile silicone compound and volatile compound, if present, are also added to the mixture, and mixed by vigorous agitation until fully dispersed. Neutralizing agent is added, if anionic polymers present, for neutralization. The high melting point compounds and cationic surfactants, if included, are added to the mixture with agitation at above 70°C by either melting such components or by dissolving such components.

Then the mixture is cooled to below 30°C, and then the remaining components, if included, are added to the mixture with agitation.

For example, the hair conditioning composition of Cond. 6 is suitably made as follows : 1. Begin with charging 95-98% of the water into the formulation vessel. While agitating the water, any polysaccharide polymers that the formula contained are added. During the dissolution or dispersion of any polymers the mixture is heated to 30-35 °C. When any added polymers are fully dispersed or dissolved, the mixture is heated to 80-85 °C.

2. Once at this temperature, all materials comprising the vehicle and frizz control agents are added while mixing vigorously. While vigorous, the mixing is not sufficient to induce significant aeration. All other minor and optional ingredients are also added at this point, with the exception of the perfume and buffer materials, and/or any other materials whose character might be compromised by the 80-85 °C temperature. This mixing stage lasts from about 5-20 minutes to ensure thorough homogenization.

3. The mixture is then cooled at a rate controlled to protect overall product integrity (this can occur by any convenient means).

4. Once the temperature drops to 30 °C, all additional ingredients are added and mixed for 10-30 minutes or until completely homogeneous. At this point, pH modifiers such as EDTA salts and/or Citric Acid salts are added to the

composition to reach the desired pH level. The preferred pH for compositions according the present invention is from about 6.0 to about 7.5.

For example, the hair conditioning composition of Cond. 7 and 8 are suitably made as follows : When included in the composition, polymeric materials such as polypropylene glycol are dispersed in water at room temperature to make a polymer solution, and heated up to above 70°C. Amidoamine and acid, other cationic surfactants, and ester oil of low melting point oil, if present, are added in the solution with agitation. Then high melting point fatty compound, other low melting point oils, and benzyl alcohol, if present, are also added in the solution with agitation. The mixture thus obtained is cooled down to below 60°C, and the remaining components such as silicone compound are added with agitation, and further cooled down to about 30°C. A triblender and/or mill can be used in each step, if necessary to disperse the materials.

The embodiments disclosed herein have many advantages. For example, the hair care kits of Examples 1-8 provide two separate hair care benefits, i. e., conditioning and styling benefits, from a single hair care product. Mixtures of the hair styling compositions and the hair conditioning compositions provided by the hair care kits of Examples 1-8 provide well-balanced conditioning and styling benefits, i. e., can provide styling benefits such as hair style achievement, and hold and retention, while delivering improved conditioning benefits such as smoothness, softness, and reduction of friction. The hair styling compositions and the hair conditioning compositions in the hair care kits of Examples 1-8 have better stability, since the compositions are isolated from each other in the kit prior to use. Furthermore, Examples 1,2, and 4-6 can also provide improved frizz control benefit, and Examples 1-5 can retain good hair feel and appearance, i. e., provide reduced sticky, greasy, and stiff feeling.

It is understood that the examples and embodiments described herein are for illustrative purposes only and that various modifications or changes in light thereof will be suggested to one skilled in the art without departing from its spirit and scope.
