preparation example Construction

[0214] The preparation of the keratin fiber conditioning compositions of the present invention may be carried out in any conventional equipment known in the art. Preferably, homogenization is performed in a high shear homogenizer, such as the IKA T25 from IKA and from of

[0215] In another aspect, the present invention also relates to the use of the following combinations of (a), (b), (c) and (d):

[0216] (a) at least one (C 10 -C 30 ) Alkylamino (C 1 -C 8 ) Alkyl (di) (C 1 -C 6 ) alkylamines and their cosmetic salts and their solvates such as hydrates, preferably stearylaminopropyldimethylamine;

[0217] (b) at least one dicarboxylic acid containing at least one hydroxyl group, preferably two hydroxyl groups, said dicarboxylic acid having no cyclic groups;

[0218] (c) at least one high-melting fatty substance having a melting point of 25°C or higher; and

[0219] (d) at least one aqueous carrier,

[0220] wherein (a), (b), (c) and (d) are used together to co...

[0223] The following examples were prepared:

[0224] Table 1

[0225]

[0226] Phase B was prepared by mixing all components and heating to 75°C, then heating Phase A to 80°C.

[0227] Mix phase A and phase B and homogenize for 1 minute with a homogenizer IKA T25 ultra-turrax. The resulting mixture was cooled to a temperature of 30°C with stirring to obtain a hair conditioning composition. All examples were evaluated using wet and dry carding methods.

[0228] Dry combing after washing

[0229] 0.4 g of Comparative Examples 1, 2, 3 and Inventive Example 4 were applied to 6 g of natural black Chinese hair. The conditioning composition is then allowed to rest on the hair for 5 minutes. Hair was then rinsed with hot water for 10 seconds and left overnight at room temperature. The friction between the hair and the polyurethane pad was measured by a Texture Analyzer supplied by Texture Technologies, Scarsdale, USA, before and after treatment with the conditioning composit...

Embodiment 5

[0244]

[0245] Phase A was prepared by mixing all components and heating to 80°C. Phase B was prepared by mixing all components and heating to 75°C. Phases A and B were mixed under stirring and immediately homogenized for 1 minute with a homogenizer IKA T25 ultra-turrax. The resulting homogeneous mixture of Phase A and Phase B was cooled to 30°C with stirring.

Abstract

The present invention relates to a keratin fibers conditioning composition, comprising: (a) at least one(C10-C30)alkylamido(C1-C8)alkyl(di)(C1-C6)alkylamine and their cosmetic salts and their solvates such as hydrates; (b) at least one dicarboxylic acid containing at least one hydroxyl group, preferably two hydroxyl groups, the said dicarboxylic acid not bearing a cyclic group; (c) at least one high melting point fatty substance having a melting point of 25 °C or higher; and (d) at least one aqueous carrier.

Description

field of invention [0001] The present invention relates to a keratin fiber conditioning composition comprising: (a) at least one (C 10 -C 30 ) Alkylamino (C 1 -C 8 ) Alkyl (di) (C 1 -C 6 ) alkylamines; (b) at least one dicarboxylic acid containing at least one hydroxyl group, said dicarboxylic acid having no cyclic groups; (c) at least one high-melting fatty substance having a temperature of 25° C. or higher and (d) at least one aqueous carrier. Background of the invention [0002] Hair conditioners have been developed over the years. As an essential ingredient, conditioning agents are always used in these hair conditioners to provide conditioning benefits. Various conditioning agents are known to provide different desired benefits. Conventional conditioners contain, for example, cationic surfactants, silicones, oils and the like. Among them, cationic surfactants are widely used as conditioning agents. The ability of such cationic surfactants to provide conditionin...
