Abstract
The invention provides personal wash compositions with soap like rinsability. The composition contains a lathering surfactant system and a specifically defined polymer/oil blend.
Claims6
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 30° C. at 1.0 S−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 30° C. at 1.0 S−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 40° 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.
