The invention relates to a composition containing the following components in a physiologically acceptable medium, namely: a) a siloxane resin comprising at least 80 mole % of units (i) (R'3Si01/2)a and (ii) (SiO4/2)b, wherein R' represents independently an alkyl group having between 1 and 8 carbon atoms, an aryl group, a carbinol group or an amino group (provided that at least 95 mole % of the R' groups are alkyl groups), a and b have values strictly greater than 0 and the a/b ratio is between 0.5 and 1.5; b) a propyl silsesquioxane resin comprising at least 80 mole % of (R"SiO3/2) units, wherein R" represents independently an alkyl group having between 1 and 8 carbon atoms, an aryl group, a carbinol group or an amino group, provided that at least 80 mole % of the R" groups are propyl groups, whereby the weight ratio between resins (a) and (b) is between 1/99 and 99/1, in particular between 85/15 and 15/85, resins (a) and (b) are not linked by covalent bonds and the number of units M in the final mixture is strictly less than the number of units (T+Q); and c) at least one wax, except candellilla wax, ozokerite and silicone waxes, said wax is preferably a hydrocarbon wax selected from the group containing beeswax, lanolin wax, rice wax, carnauba wax, ouricury wax, alfa wax, cork wool wax, sugarcane wax, Japanese wax, sumac wax, montan wax, polar waxes obtained by catalytic hydrogenation of animal or vegetable oils having linear or branched fatty chains at C8-C32, wax obtained by hydrogenation of olive oil esterified with stearyl alcohol, and waxes obtained by hydrogenation of castor oil esterified with cetyl alcohol. |
