Abstract

The invention relates inter alia to cosmetic compositions comprising an oligoester ammonium salt (OAS) and a cosmetically component (F), where the OAS is obtained by:(i) heating a mixture of the following components (a) to (d) under continuously removing of reaction water: (a) a certain a diethanolamine compound; (b) a certain dicarboxylic acid; (c) a certain organic triol; and a monocarboxylic acid of formula R1—COOH (d), wherein R1 is linear or branched C12-C24-alkyl;(ii) reacting the oligoester of step (i) with a quarternization agent.

First claim

The invention claimed is:

1. A cosmetic composition, comprising at least one oligoester ammonium salt (OAS) and at least one cosmetically acceptable component (F), whereby the at least one oligoester ammonium salt (OAS) is prepared by a process comprising the steps of:
(i) heating a mixture of components (a) to (d) while continuously removing reaction water:
0.5 to 3.0 molar equivalents of a diethanolamine compound according to formula (a)

wherein R 3 is a linear or branched C 1 -C 6 -alkyl;
0.5 to 1.5 molar equivalents of a dicarboxylic acid according to formula (b)

wherein R 2 is a linear or branched C 1 -C 10 -alkylene or a linear or branched C 2 -C 10 -alkenylene;
0.5 to 1.5 molar equivalents of an organic triol according to formula (c2)

1.0 molar equivalent of a monocarboxylic acid according to formula (d)
R 1 —COOH  (d)

wherein R 1 is linear or branched C 20 -C 24 -alkyl or linear or branched C 20 -C 24 -alkenyl;

to form an oligoester product;
(ii) reacting the oligoester product of step (i) with a quaternization agent (e);
to form the oligoester ammonium salt (OAS) and (iii) optionally removing and purifying the at least one oligoester ammonium salt (OAS).

2. The cosmetic composition comprising at least one oligoester ammonium salt (OAS) according to claim 1 , in which in the diethanolamine component (a), R 3 is methyl.

3. The cosmetic composition comprising at least one oligoester ammonium salt (OAS) according to claim 1 , in which the dicarboxylic acid (b) is selected from the group consisting of adipic acid, glutaric acid, succinic acid, sebacid acid, itaconic acid, maleic acid, and combinations thereof.

4. The cosmetic composition comprising at least one oligoester ammonium salt (OAS) according to claim 1 , in which the carboxylic acid (d) comprises or is behenic acid.

5. The cosmetic composition comprising at least one oligoester ammonium salt (OAS) according to claim 1 , in which the components (a), (b), (c2) and (d) are used in the following molar ratios: from 0.75-3.0, from 0.5-1.5, from 0.5-1.5, and 1, respectively.

6. The cosmetic composition comprising at least one oligoester ammonium salt (OAS) according to claim 1 , prepared by first heating the mixture of components (a), (b), (c2) and (d) in step (i) to a temperature from 80 to 220° C., and in step (ii) subsequent reaction of the obtained oligoester product with a quarternization agent (e).

7. The cosmetic composition comprising at least one oligoester ammonium salt (OAS) according to claim 1 , in which the oligoester ammonium salt (OAS) has a molecular mass Mn (number average) of from 600 to 4000 g/mol.

8. The cosmetic composition according to claim 1 , comprising 0.01 to 20% by weight of one or more oligoester ammonium salts (OAS) and further comprising at least 0.5% by weight of one or more further components (F), wherein the one or more further components (F) is selected from the group consisting of acidity regulators, glossers, lubricants, and further surfactants.

9. A method of preparing a cosmetic composition, according to claim 1 , comprising the step of preparing one or more oligoester ammonium salts (OAS) and mixing the OAS with one or more further components (F).

10. A method of treating hair, wherein the cosmetic composition according to claim 1 is a hair conditioner composition, comprising:
a) applying the hair conditioner composition onto wet hair and then
b) removing the conditioner composition from the hair.

11. The method according to claim 10 , comprising:
(a) applying a shampoo composition onto the hair; and then
(b) washing the hair with the shampoo composition; and then
(c) removing the shampoo composition from the hair; and then
(d) applying the hair conditioner composition onto wet hair, and then removing the conditioner composition from the hair.
