Abstract
The present invention provides high foaming aqueous liquid compositions with levels of oil/emollient equal to or in excess of level of surfactant. It is surprising that good levels of foam can be maintained at such high levels of emollient. In addition to surfactant and emollient, compositions also preferably comprise C.sub.12 -C.sub.24 fatty acid and/or cationic polymer.
Claims9
An aqueous liquid composition comprising:
- (a) 3 to 30% by weight surfactant system comprising a surfactant selected from the group consisting of anionic, amphoteric, cationic and nonionic surfactants and mixtures thereof, wherein at least one anionic surfactant must be present;
- and
- (b) 10 to 35% by weight of an oil/emollient selected from the group consisting of vegetable oils, esters, animal fats, mineral oil, petrolatum, silicone oil and mixtures thereof, wherein the level of oil/emollient is equal to or in excess of level of surfactant;
- (c) 0.1 to 8% by wt. C.sub.12 C.sub.24 fatty acid;
- (d) 0.01 to 3% by wt. cationic polymer;
- and
- (e) greater than 30% by weight water;
- wherein said composition is in a lamellar phase;
- and
- wherein said composition has a viscosity of 50,000 to 300,000 cps.
