- Composition for treating keratinous materials comprising a cationic poly(alkyl) vinyllactam polymer and a protecting or conditioning agent
-
The invention relates to a composition for treating keratin materials, in particular the hair, comprising, in a physiologically and in particular a cosmetically acceptable medium, at least one protecting or conditioning agent, and also at least one cationic poly(alkyl)vinyllactam polymer. These combinations make it possible to improve the deposition of the agent for protecting or conditioning the keratin materials and also the cosmetic properties.

- Roll-on applicator comprising a hair composition
-
A roll-on applicator comprising a container and a rotatable application member on the container, such as a container closed at one end by a closure means which can move in rotation, and means for retaining the closure means, the container containing a hair composition devoid of carboxylic surfactant, said hair composition comprising, in a cosmetically acceptable medium, at least one component chosen from: (i) anionic, amphoteric, and nonionic fixing polymers; (ii) beneficial agents; and (iii) hair dyes; wherein the roll-on applicator is capable of directly depositing on the hair said at least one component.

- Detergent cosmetic compositions containing an anionic surfactant derived from amino acids and salts thereof and an insoluble conditioning agent and uses thereof
-
Novel detergent cosmetic compositions comprising, in a cosmetically acceptable medium, (a) at least one anionic surfactant chosen from the N-acylated compounds of mono- and polyamidated polycarboxylic amino acids and the salts of said acids and (b) at least one insoluble conditioning agent. This combination imparts at least one of the cosmetic properties of sleekness, lightness and softness while minimizing keratinous fiber regreasing phenomenon. These compositions are used, for example, for washing and/or conditioning a keratinous material such as the hair and the skin.

- Method of making primary amide derivative
-
A method of selective N-acylation of an aminodiol having a primary alcoholic hydroxyl group and a secondary alcoholic hydroxyl group, in which the objective product can be prepared in high yield and without troublesome extraction and purification operations. More particularly, a method of making a primary amide derivative represented by the following general formula (3) is disclosed: STR1 wherein R1 represents a linear saturated aliphatic hydrocarbon group having 11 to 19 carbon atoms, R2 represents a linear saturated or unsaturated aliphatic hydrocarbon group having 9 to 19 carbon atoms which may have a hydroxyl group at the 1-position, which includes the steps of reacting an aminodiol represented by the following general formula (1): STR2 wherein R1 is the same as R1 in general formula (3) with a fatty acid alkyl ester represented by the following general formula (2): wherein R2 is the same as R2 in general formula (3) and R3 represents a lower alkyl group, in a reaction system comprising an alcoholic solvent and in the presence of a basic catalyst, said reacting step forming a lower alcohol as a by-product; and removing the lower alcohol formed during the reaction from the reaction system.
