Abstract

The present invention is directed to a personal care composition comprising a pre-emulsified emulsion comprising from about 0.25% to about 80% of one or more materials selected from the group comprising metathesized unsaturated polyol esters, sucrose polyesters, fatty esters with a molecular weight greater than or equal to 1500 and mixtures thereof or, by weight of said hair care composition; wherein an emulsifier is selected from the group consisting of anionic, non-ionic, cationic, amphoteric and mixtures thereof wherein the average particle size of the pre-emulsified emulsion is from about 20 nanometer to 20 microns; from about 5% to about 50% of one or more anionic surfactants, by weight of said hair care composition; at least about 20% of an aqueous carrier, by weight of said hair care composition wherein the composition is stable with respect to one of the following measures selected from emulsion particle size, viscosity or visual phase separation and mixtures thereof.

Claims

1. A personal care composition comprising:

a) from about 0.25% to about 80% of a pre-emulsified emulsion comprising from about 0.005% to about 80% of one or more materials selected from the group comprising metathesized unsaturated polyol esters, sucrose polyesters, fatty esters with a molecular weight greater than or equal to 1500 and mixtures thereof or, by weight of said hair care composition;

wherein an emulsifier is selected from the group consisting of anionic, non-ionic, cationic, amphoteric and mixtures thereof wherein the average particle size of the pre-emulsified emulsion is from about 20 nanometers to 20 microns;

b) from about 5% to about 50% of one or more anionic surfactants, by weight of said hair care composition;

c) at least about 20% of an aqueous carrier, by weight of said hair care composition

wherein the composition is stable with respect to one of the following measures selected from emulsion particle size, viscosity or visual phase separation and mixtures thereof.

2. The personal care composition of claim 1 wherein the average particle size of the pre-emulsified emulsion is from about 100 nm to 20 microns.
