A thickener-rheology modifier system for use in hair care and skin care compositions comprising: where R is H and Ris H, C&#x2013;Calkyl, or &#x2014;CHCOOX; R is &#x2014;COOX and Ris H or &#x2014;CHCOOX; and R is CHand Ris H, C&#x2013;Calkyl or &#x2014;CHCOOX; and X is H or C&#x2013;Calkyl; where Y is H or CHand Z iswhere R is Cto Calkyl; and where R is an alkyl group of 6 to 22 carbon atoms or an alkaryl of 8 to 22 carbon atom, x is an average number of from about 6 to 200, y is an average number of from about 0 to 50 and A is residue of an unsaturated carboxylic acid having the formula: were R' is H, &#x2014;COOH or CHand R&#x2033; is H, CH, &#x2014;COOH or &#x2014;CHCOOH; and Preferably the thickener-rheology modifier system will contain a surfactant and more preferably will contain boric acid.

Thickener-rheology modifier system for personal care compositions

The present invention is directed to a low VOC, non-aerosol, polyacrylic acid containing hair cosmetic compositions which contain stabilized starches, particularly those derivatized by alkylene oxides, about 01.-0.0% polyacrylic acid, up to about 15% solvent, and water. The derivatized starch may be hydrolyzed, particularly enzymatically hydrolyzed by at least one endo-enzyme. In addition, the starch may be cationically modified with a low degree of substitution. Use of such starches is novel and advantageous in that they are compatible with polyacrylic acid, providing a clear, solution with a stable viscosity. Further, the resultant composition provides a clear film which is not tacky, good stiffness, and improved humidity resistance.

Use of stabilized starches in low VOC, polyacrylic acid-containing hair cosmetic compositions

A selected thickener-rheology modifier system comprising the combination of a hydrophobically, modified alkali-soluble thickener and a polysaccharide hydrocolloid or gum or polyalkylene glycol, preferably with a surfactant and more preferably with boric acid is especially useful in personal care compositions such as hair care and skin care compositions.

The present invention is directed to low VOC, non-aerosol hair cosmetic compositions, which contain nonionically modified starches. The starch may be additionally hydrolyzed, particularly enzymatically hydrolyzed. Further, the starch may be modified using ionic substituents. Use of such starches is novel and advantageous in that they provide a clear solution with a low viscosity, and good pump spray characteristics. Further, the resultant composition provides a clear film which is not tacky, good stiffness, and improved humidity resistance.

Nonionically derivatized starches and their use in non-aerosol, low VOC hair cosmetic compositions

The present invention is directed to low volatile organic compound aerosol hair cosmetic compositions which contain nonionically derivatized starches optionally hydrolyzed and/or ionically modified, about 5-55% propellant, up to 50% solvent, and water. Such compositions provide a clear solution with a low viscosity, good spray caracteristics, a clear, non-tacky film, good stiffness, and improved humidity resistance.

Aerosol hair cosmetic compositions containing non-ionically derivatized starches

This invention involves skin cleaning products and tapes for removing keratotic plugs, dirt and other debris found on the skin and in skin pores and comprising a poly(vinyl acetamide) polymer based adhesive composition applied to a substrate backing material.

Poly(vinyl acetamide) adhesive for skin cleaning tape

A composition for treating keratin substances comprising selected amphoteric polysaccharide derivatives, preferably guar gum which contain a cationic group comprising an amino, ammonium, imino, sulfonium or phosphonium group and an anionic group comprising a carboxyl, sulfonate, sulfate, phosphate or phosphonate group.
