Abstract

The present invention relates to a personal care composition comprising a three dimensional gel polymeric network comprising:

a. a polymer;

b. one or more solid particles that are entrapped within said polymer during polymerization of said polymer; and

c. a solvent in which said polymer is dispersed.

Another embodiment further includes at least one second colorant that is substantially similar to an at least one first colorant which is a solid particle and wherein said second colorant is dispersed within said composition but is not entrapped in said polymer and is separate and distinct from said network. In contrast, a third embodiment allows for the at least one second colorant to be substantially different from the at least one first colorant.
