Abstract

A cosmetic composition and a method of preparing the cosmetic composition are provided. The method includes mixing at least one sulfate-free surfactant, at least one thickener, at least one hydrophilic emollient to form a mixture; and adding solvent to the mixture. The cosmetic composition is a clear, flowable semi-solid, and converts to a non-flowable semi-solid upon rubbing.

First claim

What is claimed is:

1. A cleansing cosmetic composition consisting of:
sulfate-free surfactants consisting of Disodium Laureth Sulfosuccinate (and) Sodium Lauryl Sulfoacetate and Coco-Betaine present in a combined amount from about 6% to about 28% by weight based on the total weight of the composition, the Coco-Betaine being present in the composition in an amount from about 3% to about 20% by weight, based on the total weight of the composition;
from about 1% to about 25 wt % of at least one thickener selected from the group consisting of Propylene Glycol (and) PEG-55 Propylene Glycol Oleate, steareth-100/PEG-136/HDI copolymer, PEG-120 methyl glucose trioleate, and combinations thereof;
from about 1% to about 2% of at least one hydrophilic emollient comprising PEG-7 Glyceryl Cocoate;
from about 50% to about 70 wt % of solvent selected from the group consisting of water, caprylyl glycol, and combinations thereof; and
optionally, one or more additional components selected from the group consisting of a/n: actives selected from a/n humectant, antimicrobial, antioxidant, preservative, vitamin, vitamin derivative; and a/n filler, penetrant, fragrance, dispersant, film-forming agent; ceramide; anti-acne, anti-aging, and combinations thereof,
wherein the cosmetic composition is a clear, flowable semi-solid, and converts to a non-flowable semi-solid upon rubbing.

2. The composition of claim 1 , wherein each sulfate-free surfactant is present from about 2% to about 25% by weight, and wherein the at least one thickener comprises one or more of: PEG-120 methyl glucose trioleate present from about 3% to about 15% by weight, steareth-100/PEG-136/HDI copolymer present from about 2% to about 20% by weight, and Propylene Glycol (and) PEG-55 Propylene Glycol Oleate present from about 2% to about 20% by weight, all weights based on the total weight of the composition.
