Abstract

Described herein, are personal care compositions comprising a surfactant system; an amino acid, e.g. taurine; and a deposition aid comprising a PVM/MA copolymer having a M.W. of from about 30,000 to about 1,000,000, or a vinylimidazolium vinyl pyrrolidone copolymer. Methods of making and using these compositions are also described.

First claim

What is claimed is:

1. A personal care composition comprising a bar soap, wherein the personal care composition comprises:
a combination of taurine, arginine, and glycine; and
sodium lauryl ether sulfate, cocamidopropyl betaine, triclocarban, cocomonoethanolamide, glycerin, PPG-2 hydroxyethyl cocamide, ethoxylated fatty alcohol, opacifier, citric acid, NaCl, pearlizer, tetrasodium EDTA, sodium benzoate, sodium salicylate, and 1-methyl-3-vinylimidazolium methyl sulfate-N-vinyl-2-pyrrolidone copolymer (Polyquaternium 44).

2. The personal care composition of claim 1 , wherein the 1-methyl-3-vinylimidazolium methyl sulfate-N-vinyl-2-pyrrolidone copolymer (Polyquaternium 44) is present in the composition in an amount of from 0.01% to 2%, or from 0.01% to 1%, or from 0.03% to 1%, or from 0.05% to 0.08%, or from 0.06% to 0.07%, by weight of the composition.

3. The personal care composition of claim 1 , wherein the composition comprises sodium lauryl ether sulfate, cocamidopropyl betaine, cocomonoethanolamide, PPG-2 hydroxyethyl cocamide and ethoxylated fatty alcohol in a combined amount of from about 5% to about 30%, or from about 5% to about 25%, or from about 10% to about 20%, or from about 12% to about 18%, or from about 14% to about 16%, by weight of the composition.

4. The personal care composition of claim 1 , wherein the sodium lauryl ether sulfate is present in the composition in an amount of from about 1% to about 15%, or from about 2% to about 12%, or from about 6% to about 10%, or from about 7% to about 10%, or from about 8% to about 9%, by weight of the composition.

5. The personal care composition of claim 1 , wherein the combination of taurine, arginine, and glycine is are present in the composition in an amount from 0.001% to 5% by weight of the composition.

6. The personal care composition of claim 1 , wherein the taurine, arginine, and glycine are present in the composition in a weight ratio of 65:34:1.

7. The personal care composition of claim 1 , wherein the personal care composition further comprises one or more additional active or inactive ingredients selected from rheology modifiers, skin lubricants, analgesics, preservatives, conditioners, antibacterial agents, chelating agents, emulsifiers, antioxidants, pH regulating agents, thickeners, proteins, plant extracts, perfumes, dyes and coloring agents, amino acids and fragrances.
