ABSTRACT:
The present invention relates to compositions, kits comprising these compositions, and methods for using these compositions for care, treatment or durable conditioning of at least one keratinous fiber, including human keratinous fibers, comprising (i) at least one compound comprising at least two quaternary ammonium groups, and (ii) at least one sugar chosen from C

monosaccharides. These compositions may be. used to care for, treat and durably condition keratinous fibers.
Shampoos generally comprise surfactants, such as anionic surfactants, to clean the hair. It is known that anionic surfactants not only remove the dirt and soil but also remove the naturally-present sebum from hair. Thus, shampoos may leave the hair dull and dry, that is, with what is known in the art as “creak”. This generally makes the hair extremely difficult to comb either wet or dry, and once dry, the hair may not be amenable to styling, and may have undesirable electrostatic properties, causing the hair to “fly away.” Due to the unsatisfactory condition of shampooed hair, many consumers use a conditioning composition to improve at least one of these undesirable characteristics.
Conditioning agents in the prior art include cationic compounds such as cationic surfactants and cationic polymers which may render the hair more manageable, at least temporarily. For example, quaternized ammonium compounds may be used as hair conditioning agents. These compounds may be substantive to the hair due to the ionic interaction between their positive charge on the ammonium nitrogen atom and negative charges on the surface of the hair fibers. This ionic interaction, in effect, allows the conditioning agents to coat the hair shaft and thereby prevent tangling and matting of the individual hair fibers. Thus, the ability of these cationic compounds to adsorb to and/or react with the keratinous material of the hair makes them desirable compounds for conditioning the hair, such as for detangling wet hair and imparting manageability to dry hair.
Conditioning agents may be comprised in a composition distinct from the shampoo composition or may be incorporated into the shampoo composition itself. For example, quaternized ammonium compounds have been included in compositions such as shampoos, conditioners and treatments that are normally applied to hair at room temperature. However, the effect of these conditioning agents may not be long lasting. Normally, because of the weak ionic bond between the quaternized ammonium compounds and the hair fiber, the quaternized ammonium compounds are washed off the hair easily. This is especially true during shampooing, wherein anionic surfactants are present, generally in high concentrations. In such a case, the anionic surfactants in the shampoo and the cationic conditioning agents are known to form a complex which may be easily removed from the hair during the shampooing and/or which decreases the cleansing capabilities of the anionic surfactant and the conditioning capabilities of the conditioning agent.
Accordingly, in practice, most consumers prefer to apply, at room temperature, an anionic surfactant-based shampoo to cleanse the hair, then rinse the hair, follow rinsing by application of a conditioner composition including a cationic compound to condition the hair, then rinse the hair again. As discussed above, this may only lead to temporary conditioning of the hair, as the next shampoo may remove the majority of the conditioning agents from the hair. Thus, there is a need for compositions and methods that impart a durable conditioning to the hair.
Sugars and sugar derivatives are one class of the countless number of compounds that have been added to hair care compositions. Documented uses of sugars in hair care compositions include: the use of glucose to improve the tactile and elastic properties of natural hair (Hollenberg and Mueller,
SOFWJ.
121(2) (1995)); the use of glucose for hair damage prophylaxis and damaged hair repair (Hollenberg & Matzik,
Seifen, Oele, Fette, Wachase
117(1) (1991)); the use of glucose in shampoos (J04266812, assigned to Lion Corp.); the use of trehalose for moisture retention (J06122614, assigned to Shiseido Co. Ltd.); a composition for the lanthionization of hair comprising a sugar (U.S. Pat. Nos. 5,348,737 and 5,641,477, assigned to Avlon Ind. Inc.); the incorporation of xylobiose into cosmetic compositions to provide enhanced moisture retention and reduce excessive roughness and dryness of the skin and hair (U.S. Pat. No. 5,660,838, assigned to Suntory Ltd.); a composition for the regeneration of hair split-ends that contains at least one mono- or di-saccharide (U.S. Pat. No. 4,900,545, assigned to Henkel); hair care compositions to improve hair strength, hold and volume that contain C5 to C6 carbohydrates such as glucose; the use of fucose in a hair treatment to prevent split ends (DE29709853, assigned to Goldwell GMBH); and the use of saccharides in a shampoo to improve combing properties and control hair damage (J09059134, assigned to Mikuchi Sangyo KK).
In essence, sugars have been applied to hair for countless reasons from moisturizing to enhancing hair growth (J10279439, assigned to Kureha Chem. Ind. Co. Ltd.). Clearly, however, not all sugars are the same and not all sugars impart the same properties when applied to a keratinous fiber.
The inventors have envisaged the application to at least one keratinous fiber of at least one composition comprising at least one compound comprising at least two quaternary ammonium groups and at least one sugar chosen from C

monosaccharides. In particular, the inventors have discovered that such compositions and methods using these compositions comprising applying them to at least one keratinous fiber and heating the at least one keratinous fiber, impart a durable conditioning to the at least one keratinous fiber. The compositions of the invention may also be used to care for, or treat, the at least one keratinous fiber.
Thus, to achieve at least one of these and other advantages, the present invention, in one aspect, provides a composition for durable conditioning of at least one keratinous fiber comprising at least one compound comprising at least two quaternary ammonium groups and at least one sugar chosen from C
