Patent ID: 7417014

Claim:
A dilution thickening cleansing composition in the form of either a solution, dispersion, emulsion or microemulsion, comprising: a. about 20 to 60% by wt. of total anionic surfactant(s); b. about 5 to 50% by wt. of total nonionic surfactant(s); c. about 5 to 80% by wt. of total water soluble block copolymer(s) d. 0 to about 40% by wt. of water; e. less than 50% by volume of a liquid crystal structured phase; and f. wherein the cleansing composition has at least one phase with a delta viscosity value of greater than about 10,000 Pa·s when blended with an equal amount of water as measured using the Standard Viscosity Method.
