Claims19
A personal care composition, comprising:
- a cosmetically acceptable carrier;
- a preservative system comprising an organic acid;
- and
- a sulfate-free surfactant system comprising:
- an anionic surfactant;
- and
- an amphoteric surfactant;
- wherein the anionic surfactant is present in an amount of from 2% to 12%, and the amphoteric surfactant is present in an amount of from 16% to 20%, based on the total weight of the personal care composition,
- wherein the anionic surfactant comprises an alpha olefin sulfonate or sodium (C14-C16) olefin sulfonate;
- wherein the amphoteric surfactant comprises cocamidopropyl betaine;
- wherein the molar ratio of the amphoteric surfactant to the anionic surfactant is about 1.5:1, wherein the term “about” means +/−5% of the reference value;
- and
- wherein the composition is substantially free of a thickening agent but maintains a viscosity of from about 2,000 centipoise (cP) to about 20,000 cP.
