Abstract:
A stress stable, mild lathering skin cleansing liquid composition comprising by weight parts of the liquid composition:(a) from about 10 parts to about 30 parts of lipid skin moisturizing agent having a Vaughan Solubility Parameter (VSP) of between 5 and 10; wherein said lipid has a shear index, n, at 35.degree. C. in the range 0.1 to 0.5 and a consistency, k, at 35.degree. C in the range 10 to 3,000 poise;(b) from about 0.5 parts to 10 parts of a stabilizer consisting essentially of non-polymeric stabilizer which is dispersed amorphous silica to stabilize the lipid skin moisturizing agent in the liquid composition and to facilitate deposition of the moisturizing agent upon application of shear, wherein said amorphous silica is selected from the group consisting of fumed and precipitated and mixtures thereof;(c) from about 5 parts to about 30 parts of lathering surfactant selected from the croup consisting of anionic surfactants, nonionic surfactants, cationic surfactants, amphoteric surfactants, and mixtures thereof wherein the nonionic surfactant is present at a concentration of from about 1 part to about 15 parts by weight and wherein the anionic surfactant comprises alkyl ether sulfates having 1 to 12 ethoxy groups; and(d) water,wherein said surfactant has a combined CMC equilibrium surface tension value of from 15 to 50; and wherein said stress stable lathering skin cleansing liquid composition has a Lipid Deposition Value (LDV) of from about 5 to about 1000.
