Abstract

Described herein, are cleansing bar compositions comprising at least one cleanser chosen from soap and surfactant; taurine, in free or salt form; and at least one polymer. Methods of making using the cleansing bar compositions are also described.

First claim

What is claimed is:

1. A cleansing bar composition comprising:
a) at least one cleanser chosen from soap and surfactant;
b) taurine particles, in free form 2-aminoethanesulfonic acid or in salt form thereof including taurine hydrochloride, taurine sulfate, taurine acetate, alkali metal salt of taurine, alkaline earth metal salt of taurine, or ammonium salt of taurine; and
c) at least one polymer selected from the group consisting of polyethylene oxide-polypropylene oxide block copolymer, polyoxyalkylene copolymer, polysorbate, polyoxyethylene sorbitan monolaurate, polyethylene, polypropylene, polyethylene glycol, polypropylene glycol, polyacrylic acid, acrylate copolymer, polyurethane, gum, xanthan gum, guar gum, gellan gum, carrageenan, acacia, gelatin, karaya gum, kelp, locust bean gum, pectin, and tragacanth gum;
wherein the taurine particles and the polymer are pre-mixed and processed to coat surface area of the taurine particles with the polymer, and
wherein the composition is a solid cleansing bar.

2. The composition of claim 1 , wherein the weight ratio of taurine to polymer is from about 1:4 to about 4:1.

3. The composition of claim 1 , wherein the taurine particles are present in an amount of 0.1% to 10% by weight of the composition.

4. The composition of claim 1 , wherein the at least one polymer comprises 0.1% to 10% by weight of the composition.

5. The composition of claim 1 , wherein the at least one polymer prevents crystallization of taurine on the surface of the cleansing bar.

6. The composition of claim 1 , wherein the at least one cleanser comprises a soap.
