Abstract:
A personal cleansing composition having soap-like rinsability comprising:(1) 70% to 99% of a lathering surfactant system containing 5 to 35% by wt. of a surfactant composition having a slippery, slightly draggy, or draggy wet skin feel during rinsing after 6 rubbing cycle as measured by in-shower rinsability evaluation method; (2) 1 to 30% by wt. of a polymer/oil blend comprising: (a) 10 to 90% of a polymer having MW greater than about 900 and viscosity greater than 10,000 centistoke at 30Â° C. at 1.0 Sâˆ’1 and a tackiness of greater than about 100 grams as measured by tackiness test; (b) 20% to 90% of a hydrophobic oil, wherein tackiness of polymer/oil blend is 30-400 g measured by tackiness test, wherein viscosity of polymer/oil blend is higher than 3000 centistoke at 30Â° C. at 1.0 Sâˆ’1; and wherein average particle size of blend is 20 to 5000 micrometers; (3) 0.1 to 10% by wt. of organic, inorganic or polymeric stabilizer in amount sufficient to provide physical stability in the surfactant system of oil droplets at 40Â° C. for over 4 weeks; wherein composition has less than 0.3 wt. % cationic polymer, wherein composition has draggy or very draggy wet skin feel in less than 8 rubbing cycles as determined by in-shower evaluation method; and wherein said polymer is selected from the group consisting of polybutene, polyisobutene, polybutadiene, polyisoprene, polyalphaolefin, polyester, polyacrylate, copolymers of the above and mixtures thereof.
