Ingredients for use in personal care compositions
A dialkyl amidoamine which is the reaction product of a polyamine, a monocarboxylic acid, or a triglyceride or derivative thereof, and optionally an epoxide-containing compound is described. The dialkyl amidoamine may be used as a conditioning agent or anti-frizz agent useful in personal care applications, particularly in the conditioning of hair. The preparation and use of a conditioning agent and an anti-frizz agent comprising the dialkyl amidoamine are also described.
1. A conditioning agent comprising at least 50% by weight based on the total weight of the conditioning agent of a dialkyl amidoamine which is the reaction product of
a) a polyamine selected from diethylene triamine (DETA) and triethylene tetramine (TETA);
b) a monocarboxylic acid that is isostearic acid, oleic acid, palmitic acid, linoleic acid or is obtained from palm oil, rape seed oil or HEAR (high erucic acid rape) oil; and
c) an epoxide-containing compound selected from ethylene oxide, propylene oxide and glycidol,
wherein tertiary amine content of the dialkyl amidoamine is >95% as determined using AOCS method Tf 3a-64, and
wherein the conditioning agent is substantially free from quaternary ammonium compounds.
2. An anti-frizz agent comprising a dialkyl amidoamine which is the reaction product of
a) a polyamine selected from diethylene triamine (DETA) and triethylene tetramine (TETA);
b) a monocarboxylic acid that is isostearic acid, oleic acid, palmitic acid, linoleic acid or is obtained from palm oil, rape seed oil or HEAR (high erucic acid rape) oil; and
c) an epoxide-containing compound selected from ethylene oxide, propylene oxide and glycidol,
wherein tertiary amine content of the dialkyl amidoamine is >95% as determined using AOCS method Tf 3a-64, and
wherein the anti-frizz agent is substantially free from quaternary ammonium compounds.
3. A predispersion or presolution comprising a conditioning agent of claim 1 and a dispersing agent or solvent or mixture thereof.
4. A method of conditioning hair, comprising applying the conditioning agent of claim 1 to the hair.
5. A method of reducing frizz in hair comprising applying the anti-frizz agent of claim 2 to the hair.
6. A predispersion or presolution comprising an anti-frizz agent of claim 2 and a dispersing agent or solvent or mixture thereof.
7. The conditioning agent of claim 1 , wherein the polyamine is diethylene triamine (DETA).
8. The anti-frizz agent of claim 2 , wherein the polyamine is diethylene triamine (DETA).
9. A personal care formulation comprising a conditioning agent of claim 1 and a viscosity modifier.
10. A personal care formulation comprising an anti-frizz agent of claim 2 and a viscosity modifier.
11. A personal care formulation according to claim 9 , wherein the viscosity modifier is a fatty alcohol.
12. A personal care formulation according to claim 10 , wherein the viscosity modifier is a fatty alcohol.
13. A personal care formulation comprising a conditioning agent of claim 1 and sodium lauryl ether sulphate or cocamidopropyl betaine.
14. A personal care formulation comprising an anti-frizz agent of claim 2 and sodium lauryl ether sulphate or cocamidopropyl betaine.
15. A hair care formulation comprising a conditioning agent of claim 1 .
16. A hair care formulation comprising an anti-frizz agent of claim 2 .
17. The conditioning agent of claim 1 , wherein the polyamine is diethylene triamine (DETA), the monocarboxylic acid is from palm oil and the epoxide-containing compound is ethylene oxide.
18. The anti-frizz agent of claim 2 , wherein the polyamine is diethylene triamine (DETA), the monocarboxylic acid is from palm oil and the epoxide-containing compound is ethylene oxide.
19. The conditioning agent of claim 1 , wherein hair treated with the conditioning agent requires a lower combing force compared to untreated hair.
20. The conditioning agent of claim 1 , wherein the treated hair is wet.
21. The conditioning agent of claim 1 , wherein the treated hair is dry.
22. The anti-frizz agent of claim 2 , wherein hair treated with the anti-frizz agent exhibits more frizz control compared to untreated hair.
