Abstract

The invention relates to a composition which contains at least one N-acyl-amino acid surfactant, a betaine surfactant, an N-methyl-N-acylglucamine, said N-methyl-N-acylglucamine having a C 16 -C 20 -acyl group, and further contains a solvent and optionally one or more additives. The invention also relates to a method for producing the composition. The invention further relates to the use of the composition for the treatment or care of skin or hair, or for use as a shampoo, face cleaner, liquid cleaner or shower gel.

First claim

The invention claimed is:

1. A composition comprising:
(A) at least one N-acylamino acid surfactant as component A,
(B) at least one betaine surfactant as component B,
(C) at least one N-methyl-N-acylglucamine as component C, wherein the N-methyl-N-acylglucamine has a C 16 -C 20 -acyl radical,
(D) at least one solvent as component D, and
(E) optionally one or more additives as component E.

2. The composition as claimed in claim 1 , comprising:
(A) from 5 to 15% by weight of component A,
(B) from 1 to 10% by weight of component B,
(C) from 1 to 10% by weight of component C,
(D) from 10 to 93% by weight of a protic solvent as component D, and
(E) from 0 to 10% by weight of component E,
wherein the sum of components A to E is 100% by weight.

3. The composition as claimed in claim 1 , wherein the amino acid radical of component A is selected from the group consisting of proteinogenic amino acids, their N-alkylated derivatives and mixtures thereof.

4. The composition as claimed in claim 1 , wherein component A consists of at least one C 8 -C 22 -acylated amino acid.

5. The composition as claimed in claim 1 , wherein component A is selected from the group consisting of acyl glycinate, acyl aspartate, acyl glutamate, acyl sarcosinate and mixtures thereof.

6. The composition as claimed in claim 1 , wherein component B comprises at least one alkyl betaine and/or at least one alkylamido betaine.

7. The composition as claimed in claim 1 , wherein component C consists of a mixture of N-methyl-N-acylglucamines, wherein at least 80% by weight of the N-methyl-N-acylglucamines have a saturated or unsaturated C 16 - or C 18 -acyl radical.

8. The composition as claimed in claim 1 , wherein the solvent of component D is water or a mixture of water and propylene glycol.

9. The composition as claimed in claim 1 , wherein the composition is free of alkyl sulfates and/or alkyl ether sulfates.

10. The composition as claimed in claim 1 , wherein the sum of components A, B and C is from 7 to 20% by weight.

11. The composition as claimed in claim 1 , wherein the one or more additives are selected from the group consisting of preservatives, fragrances, dyes, further surfactants, water, oily substances, cationic polymers, film-forming agents, thickeners and gelling agents, superfatting agents, antimicrobial and biogenic active ingredients, moisture-donating agents, stabilizers, acids, lyes, activity enhancers, and mixtures thereof.

12. The composition as claimed in claim 1 , wherein the composition is a cosmetic, dermatological or pharmaceutical composition.

13. A method for preparing the composition as claimed in claim 1 , comprising the steps:
a) mixing component E with D to form a solution,
b) adding component A to the solution from step a),
c) mixing component D with optionally a further component E and then adding to the solution from step b) to form a solution,
d) adding components B and C to the solution from step c), and
e) adjusting the pH of the composition to a range of 6.8 to 7.5.

14. A shampoo, facial cleanser, liquid cleanser or shower gel comprising a composition as claimed in claim 1 .

15. A skin treatment or skin care product comprising a composition as claimed in claim 1 .

16. A hair treatment or hair care product comprising a composition as claimed in claim 1 .
