Abstract
An emulsifier-free composition includes in a water phase a hydroxy acid system that includes alpha hydroxy, a blend of low pH, high electrolyte compatible thickeners and in an oily phase one or a combination of emollient oils. The composition has a pH in the range from about 1 to about 5.0 and is essentially free of emulsifiers and comprises a gel cream architecture.
Claims20
A cosmetic composition comprising:
- a) a water phase, comprising;
- i. a hydroxy acid system comprising alpha hydroxy acid;
- ii. a primary low pH, high electrolyte compatible thickener comprising Hydroxyethyl Acrylate/Sodium Acrrloyldimethyl Taurate Copolymer;
