Abstract
The disclosure provides a personal care composition and method for forming the composition wherein the SCC polymer has at least one functionality selected from the group consisting of silicone, hydroxyl and carboxy. Such functionalized SCC polymers can be employed in a wide range of personal care compositions including skin care, body wash, and shampoo and hair treatments, among other personal care products.

1-22. (canceled)
A personal care composition comprising
- water,
- at least one oil or one emollient,
- at least one side chain crystalline polymer wherein said polymer comprises C8 alkyl acrylates/methacrylic acid crosspolymer;
- at least one emulsifier, and;
- at least one active compound that interacts with skin or hair.
A personal care composition comprising
- about 50 to about 90 wt % water,
- about 6 to about 30 wt % at least one member selected from the group consisting of oils and emollients,
- about 0.5 to about 6 wt % at least one side chain crystalline polymer which contains at least one functional group selected from the group consisting of hydroxyl groups;
- about 0.5 to about 5 wt % at least one emulsifier;
- and,
- about 1 to about 25 wt % of at least one active compound that interacts with skin or hair, the active compound being selected from the group consisting of skin whiteners, aluminum chlorohydrate, aluminum zirconium tetra chlorohydrex, alpha hydroxyl acids, and coenzymes and enzymes;
- and,
- about 0.1 to about 3.0 wt % other additives;
- wherein the personal care composition is devoid of other film forming polymers.
A personal care composition consisting essentially of:
- water,
- at least one oil or one emollient,
- at least one side chain crystalline polymer wherein said polymer comprises C8 alkyl acrylates/methacrylic acid crosspolymer;
- at least one emulsifier, and;
- at least one active compound;
- wherein the personal care composition is devoid of sunscreen actives.
A personal care composition consisting essentially of:
- water,
- at least one member selected from the group consisting of oils and emollients,
- at least one side chain crystalline polymer which contains at least one functional group selected from the group consisting of carboxy, silicone and hydroxyl groups;
- wherein the side chain crystalline polymer dissolves into the at least one member at a temperature above the crystalline melting point of the side chain crystalline polymer;
- at least one emulsifier;
- and,
- at least one active compound that interacts with skin or hair;
- wherein the personal care composition is an emulsion;
- wherein the personal care composition is devoid of sunscreen additives and other film forming polymers.
A personal care composition comprising
- an oil in water emulsion,
- at least one C12-C22 side chain crystalline polymer which contains at least one hydroxyl functional group wherein the side chain crystalline polymer has a crystalline melting point from 40 to 70° C.;
- and,
- at least one active compound that interacts with skin wherein the active compound is incorporated into a crystalline matrix of the side chain crystalline polymer and wherein the active ingredient is released from the crystalline matrix at body temperatures;
- wherein the personal care composition is devoid of sunscreen actives.
