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

The present invention relates to new cosmetic compositions, in particular hair 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 conditioners comprising a cationic surfactant and fatty alcohols make it possible to obtain good cosmetic properties for the hair. However, the user sometimes has the feeling that his hair is heavy, not very light, and that it regreases easily, especially if his hair is fine, moreover for certain types of hair the cosmetic properties are not sufficient. In addition, the distribution of the product is sometimes difficult.

<patcit id="pcit0001" dnum="WO9962492A"><text>WO99 / ​​62492</text></patcit> describes hair conditioning compositions containing fatty alcohols, cationic surfactants, cationic polymers but not containing a diol having 6 carbon atoms.

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, made it possible to remedy the drawbacks mentioned above.

In particular, it found that these compositions allowed softening of the fiber, that is to say made the fiber less rough and more malleable.

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

Finally, she noted that these compositions imparted good cosmetic properties to the hair, and in particular the disentangling, the straightening, that the hair was light and regreased less quickly, and that the hair was shaped very easily, and durably.

The subject of the present invention is therefore a cosmetic composition, in particular a hair 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.
