Abstract

The present disclosure relates to gentle cleansing compositions, which generally include: (a) a taurate surfactant; (b) an isethionate surfactant; (c) a betaine (and/or another amphoteric surfactant); and (d) a nonionic emulsifier. The cleansing compositions exhibit very good cleansing properties, are particularly effective for removing makeup, and are mild and moisturizing to the skin.

First claim

The invention claimed is:

1. A cleansing composition comprising 50 to 92 wt. % water, and:
a. 1 to 15 wt. % of a taurate surfactant;
b. 0.1 to 15 wt. % of an isethionate surfactant;
c. 0.1 to 15 wt. % wt. % of a betaine; and
d. 0.01 to 10 wt. % of a nonionic emulsifier selected from the group consisting of a polyol ester, a glycerol ether, an oxyalkylenated fatty acid ether, an oxyalkylenated fatty acid ester, and a mixture thereof;
wherein the composition is essentially free of sulfates.

2. The cleansing composition of claim 1 , wherein the taurate surfactant of (a) a compound selected from the group consisting of sodium methyl lauroyl taurate, sodium methyl myristoyl taurate, potassium methyl myristoyl taurate, sodium methyl cocoyl taurate, sodium methyl oleoyl taurate, calcium methyl lauroyl taurate, potassium methyl lauroyl taurate, and ammonium methyl lauroyl taurate.

3. The cleansing composition of claim 2 , wherein the taurate surfactant is sodium methyl cocoyl taurate.

4. The cleansing composition of claim 1 , wherein the isethionate surfactant of (b) a compound selected from the group consisting of sodium lauroyl isethionate, sodium lauroyl methyl isethionate, sodium myristoyl isethionate, sodium cocoyl isethionate, sodium oleoyl isethionate, and ammonium oleoyl isethionate.

5. The cleansing composition of claim 4 , wherein the isethionate surfactant is sodium cocoyl isethionate.

6. The cleansing composition of claim 1 , wherein the betaine of (c) is selected from the group consisting of coco betaine, cocoamidopropyl betaine, lauryl betaine, laurylhydroxy sulfobetaine, lauryldimethyl betaine, cocoamidopropylhydroxylsulfo betaine, behenyl betaine, capryl/capramidopropyl betaine, lauryl hydroxysultaine, and stearyl betaine.

7. The cleansing composition of claim 6 , wherein the betaine is coco betaine.

8. The cleansing composition of claim 1 , wherein the nonionic emulsifier of (d) comprises a polyol ester and an oxyalkylenated fatty acid ester.

9. The cleansing composition of claim 8 , wherein the nonionic emulsifier of (d) comprises glyceryl stearate and PEG-100 stearate.

10. The cleansing composition of claim 1 , further comprising:
e. a conditioning polymer.

11. The cleansing composition of claim 10 , wherein the conditioning polymer of (e) is selected from the group consisting of a homopolymer or a copolymer derived from acrylic or methacrylic esters or amides, a polysaccharide, a polyamino amide derivative, quaternary diammonium polymers, polyquaternary ammonium polymers, a cationic cellulose or cellulose derivative, and a cationic protein.

12. The cleansing composition of claim 11 , wherein the conditioning polymer of (e) is homopolymer or copolymer derived from acrylic or methacrylic esters or amides.

13. The cleansing composition of claim 12 , wherein the conditioning polymer of (e) is a copolymer of acrylic acid, acrylamide, and methacrylamidopropyltrimonium chloride.

14. The cleansing composition of claim 11 , further comprising:
(f) a rheology modifier.

15. A cleansing composition comprising 50 to 92 wt. % water:
(a) 1 to 15 wt. % of a tauruate surfactant;
(b) 0.1 to 15 wt. % of an isethionate surfactant;
(c) 0.1 to 15 wt. % of a betaine;
(d) 0.01 to 10 wt. % of a nonionic emulsifier selected from the group consisting of a polyol ester, a glycerol ether, an oxyalkylenated fatty acid ether, an oxyalkylenated fatty acid ester, and a mixture thereof;
(e) 0.01 to 5 wt. % of a polyquaternium; and
(f) 0.01 to 5 wt. % of a rheology modifier;
wherein the composition is essentially free of sulfates.

16. A method for cleansing the face comprising applying the cleansing composition of claim 1 to the face, thereby cleansing the face.

17. A method for removing makeup from skin comprising applying the cleansing composition of claim 1 to skin upon which makeup has already been applied, thereby removing the makeup from the skin.

18. A cleansing composition of claim 15 , wherein the nonionic emulsifier of (d) comprises a polyol ester and an oxyalkylenated fatty acid ester.

19. A cleansing composition of claim 15 comprising:
(a) 1 to 15 wt. % of sodium methyl cocoyl taurate;
(b) 0.1 to 15 wt. % of sodium cocoyl isethionate;
(c) 0.1 to 15 wt. % of coco betaine;
(d) 0.01 to 10 wt. % of glyceryl stearate and PEG-100 stearate;
(e) 0.01 to 5 wt. % of a polyquaternium; and
(f) 0.01 to 5 wt. % of a homopolymer or copolymer derived from acrylic or methacrylic esters or amides.

20. A cleansing composition of claim 19 , wherein the polyquaternium is polyquaternium-53.
