Abstract
Disclosed are water-based personal cleansing compositions having an isotropic surfactant phase, the compositions containing (a) cationic surfactant that includes a quaternary ammonium compound and/or an amidoamine, (b) cleansing surfactant and (c) water, the cleansing surfactant containing 85 to 100% by weight of a combination of betaine surfactant and taurate surfactant in particular ratios; also disclosed are methods of thickening such compositions by the addition of electrolyte.
Claims19
A personal cleansing composition comprising:
- a) a cationic surfactant comprising an amidoamine
- b) 5 to 15 wt. % cleansing surfactant, and
- c) water,
- wherein:
- the cleansing surfactant contains from 85 to 100% by weight of a combination of betaine surfactant and taurate surfactant, wherein the taurate surfactant is an acyl taurate represented by the general formula:
- R8C(O)N(R9)(CH2)ySO3M (IIIa)
- where R9 is C6 to C30 alkyl,
- y is 2 or 3,
- R9 is hydrogen or methyl, and
- M is a solubilizing cation, and wherein:
- when the composition contains 5 to 6 weight percent of cleansing surfactant, the weight ratio of betaine surfactant to taurate surfactant is from 55:45 to 45:55;
- when composition contains from greater than 6 weight percent to up to 10 weight percent of cleansing surfactant, the weight ratio of betaine surfactant to taurate surfactant is from 80:20:
- to 40:60;
- and
- when the composition contains greater than 10 weight percent of cleansing surfactant, the weight ratio of betaine surfactant to taurate surfactant is from 80:20:
- to 20:80;
- wherein the composition further comprises electrolyte;
- wherein the personal cleansing composition is essentially free of a cationic derivative of guar gum;
- wherein the composition is essentially free of (meth)acrylate polymers and copolymers;
- wherein the composition is essentially free of sulfate surfactant.
