BACKGROUND Human hair becomes soiled due to its contact with the surrounding environment and from sebum secreted by the scalp. The soiling of the hair causes it to have a dirty or greasy feel, and an unattractive appearance. The soiling of the hair necessitates shampooing with 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. The hair can further be left with increased levels of static upon drying which can interfere with combing and result in a condition commonly referred to as"fly-away hair", or contribute to an undesirable phenomena of"split ends", particularly for long hair.

A variety of approaches have been developed to alleviate these after- shampoo problems. These approaches range from post-shampoo application of hair conditioner such as lave-on and rinse-off products, to hair conditioning shampoos which attempt to both cleanse and condition the hair from a single product. Although some consumers prefer the ease and convenience of a shampoo which inclues 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. 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 portion of hair.

Conditioning formulations can be in the form of rinse-off products or leave- on products, and can be in the form of an mulsion, cream, gel, spray, and mousse. Products in the form of cream, gel, and mousse are suitable in that the consumer can easily control the amount and distribution of the product. As such, these products are particularly suitable for lave-on products.

Leave-on products having aesthetic advantages are preferred by the consumer. Transparent or nearly transparent products including distinct visible particles are particularly preferred with regard to aesthetics. Such visible particles are also useful in encompassing materials which may affect the stability of the base formula. However, conventional lave-on products are not completely satisfactory in providing such aesthetic effects while delivering good conditioning benefits.

Based on the foregoing, there remains a desire to provide hair conditioning compositions suitable for leave-on use which provide favorable aesthetic benefits, and are compatible with a wide range of additional conditioning agents.

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 conditioning composition comprising: (1) a hydrophobic emulsifier selected from the group consisting of carboxylic acid/carboxylate copolymer, nonionic surfactant having an HLB of from about 1 to about 10, silicone derivative surfactant, and mixtures thereof; (2) a breakable visible particle comprising structural material selected from the group consisting of polysaccharides and their derivatives, saccharides and their derivatives, oligosaccharides, monosaccharides, and mixtures thereof; and (3) an oily continous phase carrier; wherein the composition is transparent.

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.

Patent No. 4,152,416, to Spitzer et a/., issued May 1,1979 and Noll, Walter, Chemistry and Technology of Silicones, New York: Academic Press 1968. Also describing silicone gums are General Electric Silicone Rubber Product Data Sheets SE 30, SE 33, SE 54 and SE 76. The"silicone gums"will typically have a mass molecular weight in excess of about 200,000, generally between about 200,000 and about 1,000,000. Specific examples include polydimethylsiloxane, poly (dimethylsiloxane methylvinylsiloxane) copolymer, poly (dimethylsiloxane diphenylsiloxane methylvinylsiloxane) copolymer and mixtures thereof.

Also useful are silicone resins, which are highly crosslinked polymeric siloxane systems. The crosslinking is introduced through the incorporation of tri- functional and tetra-functional silanes with mono-functional or di-functional, 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: silicon atoms is at least about 1.2: 1.0. Silanes used in the manufacture of silicone resins include monomethyl-, dimethyl-, trimethyl-, monophenyl-, diphenyl-, methylphenyl-, monovinyl-, and methylvinylchlorosilanes, and tetrachlorosilane, with the methyl substituted silanes being most commonly utilized. Preferred resins are offered by General Electric as GE SS4230 and SS4267. Commercially available silicone resins will

generally be supplie in a dissolved form in a low viscosity volatile or nonvolatile silicone fluid. The silicone resins for use herein should be supplie and incorporated into the present compositions in such dissolved form, as will be readily apparent to those skilled in the art. Without being bound by theory, it is believed that the silicone resins can enhance deposition of other silicone compounds on the hair and can enhance the glossines of hair with high refractive index volumes.

Other useful silicone resins are silicone resin powders such as the material given the CTFA designation polymethylsilsequioxane, which is commercially available as Tospearl'from Toshiba Silicones.

The method of manufacturing these silicone compounds, can be found in Encyclopedia of Polymer Science and Engineering, Volume 15, Second Edition, pp. 204-308, John Wiley & Sons, Inc., 1989.

Silicone materials and silicone resins in particular, can conveniently be identified according to a shorthand nomenclature system well known to those skilled in the art as the"MDTQ"nomenclature. Under this system, the silicone is described according to the presence of various siloxane monomer units which make up the silicone. Briefly, the symbol M denotes the mono-functional unit (CH3) gSiOo5 5 ; D denotes the difunctional unit (CH3) 2SiO; T denotes the trifunctional unit (CH3) Sil. 5; and Q denotes the quadri-or tetra-functional unit Si02. Primes of the unit symbols, e. g., M', D', T', and Q'denote substituents other than methyl, and must be specifically defined for each occurrence. Typical alternate substituents include groups such as vinyl, phenyl, amino, hydroxyl, etc.

The molar ratios of the various units, either in terms of subscripts to the symbols indicating the total number of each type of unit in the silicone, or an average thereof, or as specifically indicated ratios in combination with molecular weight, complete the description of the silicone material under the MDTQ system.

Higher relative molar amounts of T, Q, T'and/or Q'to D, D', M and/or or M'in a silicone resin is indicative of higher levels of crosslinking. As discussed before, however, the overall level of crosslinking can also be indicated by the oxygen to silicon ratio.

The silicone resins for use herein which are preferred are MQ, MT, MTQ, MQ and MDTQ resins. Thus, the preferred silicone substituent is methyl.

Especially preferred are MQ resins wherein the M: Q ratio is from about 0.5: 1.0 to about 1.5: 1.0 and the average molecular weight of the resin is from about 1000

to about 10,000.

Particularly suitable silicone compounds herein are non-volatile silicone oils having a molecular weight of from about 200,000 to about 600,000 such as Dimethicone, and Dimethiconol. These silicone compounds can be incorporated in the composition as silicone oils solutions; the silicone oils being volatile or non- volatile.

Method of Preparation The hair conditioning products of Examples 1 through 6 are suitably made as follows: oils for the carrier, hydrophobic emulsifier, and high molecular weight ester oils and silicone compounds, if included, are mixed until homogenous. To this is added the breakable visible particles and mixed with vigorous agitation to make a first premix. In a separate container, the remaining components are dissolved in water and/or ethanol to make a second premix. The first and second

premixes are blended with agitation until homogenous. A triblender can be used as necessary to disperse the components.

Examples 1 through 6 are hair conditioning compositions of the present invention which are particularly useful for leave-on use. These examples have many advantages. For example, they are transparent and show the breakable visible particles distinctively. They can further provide improved conditioning benefits to the hair such as smoothness, softness, and reduction of friction, and are easy to apply on the hair. The breakable visible particles readily disintegrate with little shear on the hand with the fingers.

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.
