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, in free or salt form; and c) at least one polymer; wherein the composition is a solid cleansing bar.

2 . The composition of claim 1 , wherein the taurine is substantially coated by the polymer.

3 . The composition of claim 1 , wherein the taurine is in free form.

4 . The composition of claim 1 , wherein the taurine is in salt form and is selected from the group consisting of taurine hydrochloride, taurine sulfate, taurine acetate, alkali metal salt of taurine, alkaline earth metal salt of taurine, or ammonium salt of taurine.

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

6 . (canceled)

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

8 . (canceled)

9 . (canceled)

10 . (canceled)

11 . The composition of claim 1 , wherein the at least one polymer is 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.

12 . (canceled)

13 . (canceled)

14 . (canceled)

15 . (canceled)

16 . The composition of claim 11 , wherein the at least one polymer, e.g., the polyethylene oxide-polypropylene oxide block copolymer, comprises 0.1% to 10% by weight of the composition.

17 . (canceled)

18 . (canceled)

19 . (canceled)

20 . The composition of claim 1 , wherein the at least one polymer, e.g., the polyethylene oxide-polypropylene oxide block copolymer, prevents crystallization of taurine on the surface of the cleansing bar.

21 . The composition of claim 1 , wherein the at least one cleanser comprises a soap, for example, an alkali metal or alkylammonium salt of a C8-C22 carboxylic acid.

22 . A method of inhibiting taurine crystallization in a cleansing bar comprising
a) combining taurine, in free or salt form in a polymer to form a mixture; b) adding the mixture to at least one cleanser chosen from soap and surfactant; and c) forming a cleansing bar.

23 . The method of claim 22 , wherein the taurine is substantially coated by the polymer.

24 . The method of claim 22 , wherein the taurine is in free form.

25 . The method of claim 22 , wherein the taurine is in salt form and is selected from the group consisting of taurine hydrochloride, taurine sulfate, taurine acetate, alkali metal salt of taurine, alkaline earth metal salt of taurine, or ammonium salt of taurine.

26 . The method of claim 22 , wherein the weight ratio of taurine to polymer is from about 1:4 to about 4:1,

27 . (canceled)

28 . The method of claim 22 , wherein the taurine is present in an amount of 0.1% to 10% by weight of the composition.

29 . (canceled)

30 . (canceled)

31 . (canceled)

32 . The method of claim 22 , wherein the at least one polymer is 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.

33 . (canceled)

34 . (canceled)

35 . (canceled)

36 . (canceled)

37 . The method of claim 32 , wherein the at least one polymer, e.g., the polyethylene oxide-polypropylene oxide block copolymer, comprises 0.1% to 10% by weight of the composition.

38 . (canceled)

39 . (canceled)

40 . (canceled)

41 . The method of claim 22 , wherein the at least one polymer prevents crystallization of taurine on the surface of the cleansing bar.

42 . The method of claim 22 , wherein the at least one cleanser is a soap, for example, an alkali metal or alkylammonium salt of a C8-C22 carboxylic acid.
