Abstract

The present invention relates to a cosmetic composition comprising one or more amino silicones, one or more cationic surfactants and one or more esters of formula R′—O—CO—R—CO—O—R″. The invention also concerns a cosmetic treatment process for keratin substances, in particular for conditioning hair, implementing said cosmetic composition.

Claims

1. A hair conditioning composition, comprising:

from 20 to 80% by weight relative to the total weight of the composition of an alcohol selected from the group consisting of ethanol and isopropanol;

water;

from 0.01 to 5% by weight of PEG-40/PPG-8 methylaminopropyl hydroxypropyl dimethicone copolymer;

from 0.2 to 5% by weight of cetyl trimethyl ammonium chloride;

from 0.05 to 5% by weight of dialkyl C12-C13 malate;

from 0.5 to 3% by weight of PPG-10 methyl glucose ether; and

from 1.5 to 7.5% by weight of a mixture of cetearyl alcohol and myristyl alcohol;

from 5% to 80% by weight relative to the total weight of the composition of at least one C₁-C₆ aliphatic monoalcohol;

from 5 to 20% by weight of water, relative to the total weight of the composition;

one or more amino silicones;

one or more cationic surfactants; and

one or more esters of formula (I);
