Claims17
A cleansing composition comprising an aqueous solution of:
- an anionic polymer;
- a nonionic polymer;
- and
- a phase-stabilizing amount of surfactants comprising a combination of at least one anionic surfactant and at least one nonionic surfactant, wherein the nonionic surfactant comprises a C8-C22 tertiary amine oxide or a fatty acid amide;
- wherein the solution comprises two distinct aqueous phases having different composition and density, the two distinct phases comprising all of one of the anionic polymer or the nonionic polymer;
- wherein the nonionic polymer comprises polyethylene glycol having a molecular weight of 5kD to 10kD in an amount of 0.1-10 wt. % of the composition;
- wherein the anionic polymer is an acidic polymer selected from a polyacrylate made of homopolymers or co-polymers of a combination of acrylic acid derivatives or a synthetic anionic linear polycarboxylate;
- and
- wherein the acidic polymer is present in an amount of 5-25 wt. % of the composition.
