Cosmetic composition based on a cationic surfactant, a fatty alcohol, a cationic non-silicone polymer and a diol

The present invention relates to novel cosmetic compositions, in particular capillary compositions, comprising at least one particular cationic surfactant, at least one cationic polymer, at least one fatty alcohol, and at least one particular diol. It also relates to the use of these compositions in cosmetics, and in particular the use of these compositions as a conditioner.

Conventional hair conditioners comprising a cationic surfactant and fatty alcohols make it possible to obtain good cosmetic properties of the hair. However, the user sometimes has the sensation that his hair is heavy, not very light, and that it is easily regreased, especially if his hair is thin, moreover for certain types of hair the cosmetic properties are not sufficient. In addition, the distribution of the product is sometimes difficult.

The Applicant has surprisingly discovered that compositions comprising at least one particular cationic surfactant, at least one non-silicone cationic polymer, at least one or more fatty alcohols with a total concentration of fatty alcohol (s) greater than or equal to 4% by weight relative to the total weight of the composition, and at least one diol having 6 carbon atoms, allowed to overcome the disadvantages mentioned above.

In particular, it has been found that these compositions allow a softening of the fiber, that is to say makes the fiber less rough and more malleable.

She also found that during the application, the compositions were distributed and spread easily from the roots to the tips, and that rinsing was particularly easy.

She finally noticed that these compositions conferred good cosmetic properties to the hair, including disentangling, smoothing, that the hair was light and regreased slower, and that the hair was shaped very easily, and durably.

The subject of the present invention is therefore a cosmetic composition, in particular a capillary composition, characterized in that it comprises, in a cosmetically acceptable medium, at least one cationic surfactant chosen from quaternary ammonium salts, at least one non-silicone cationic polymer, at least one fatty alcohol, and at least one diol having 6 carbon atoms, the total concentration of fatty alcohol (s) being greater than or equal to 4% by weight relative to the total weight of the composition.
