Abstract
The invention discloses bar compositions which are milder than soap but have squeaky feel or rinse associated with soap. This is accomplished by ensuring at least a certain portion (at least 1%), or all, of the soluble surfactant system is ion-sensitive. Further, soluble soap comprises less than 1% by wt. of bar, which helps produce a less alkaline pH bar while allowing squeaky feel to be produced.
Claims6
Bar composition comprising:
- (1) 7 to 75% by wt. of a surfactant system comprising:
- (a) 5 to 30% by wt. total composition of a component of said surfactant system wherein the component(s) are substantially insoluble in water, less than 1% solubility when measured in water at about 20° C., and wherein said components comprise:
- (i) about 16.2% by wt. insoluble alkali metal fatty acid soap;
- and
- (ii) about 5.66% by wt. of amido sulfosuccinate;
- and
- (b) 2 to 45% by wt. total composition of a component(s) of said surfactant system wherein the components are soluble and wherein said components comprise:
- (i) less than 1% by wt. soluble soap;
- (ii) about 17% by wt. of a surfactant selected from the group consisting of monoalkyl phosphate, alkoyl lactylate and mixtures thereof which surfactant(s) is sensitive to precipitation by ions in water having French Hardness of 0.1 to 30;
- and
- (2) 5 to 35% by wt. total composition of insoluble C16 to C24 free fatty acid;
- (3) 5 to 35% by wt. total composition water soluble structurants wherein said structurants comprise structurants selected from the group consisting of alkylene glycol, glycerin and mixtures thereof;
- and
- (4) 4 to 14% by wt. total composition water;
- wherein composition has pH of less than 7.5;
- and
- wherein the composition has a squeaky, non-slimy rinse value of 11 or less.
