摘要:
A cosmetic composition for makeup or skin care, in the form of a water-in-oil emulsion, comprising an aqueous phase, at least 5% by weight, with respect to the total weight of the composition, of a dispersed solid phase, and a liquid fat phase having at least a non-volatile fraction, the liquid fat phase comprising: - at least two oils chosen from oils that volatilize slowly with an evaporation rate of between 0.002 and 0.05 mg / cm2 / minute according to the protocol defined in the description, and dry oils chosen from oils with a viscosity less than or equal to 10 Cps, a surface tension between 21 and 31 mN / m and an evaporation rate of less than 0.002 mg / cm2 / minute according to the protocol defined in the description, the liquid fat phase having an evaporation rate so that the weight ratio of the total mass of the liquid fat phase after 10 minutes of drying according to the protocol defined in the description, that is, i M m (t) at>; = 10 minutes, at the initial liquid fatty phase, that is, ii M m (t) at>; = 0 minutes, ranges from 0.75 to 1, in which i represents each solvent m1 (t) represents the remaining mass of each solvent i per unit area at time t according to the following equations ** Formula ** in which vi represents the evaporation rate measured according to the protocol defined in the description and expressed in mg of oil evaporated per unit area (cm2) and per unit time (minutes), and the aqueous phase and the liquid fatty phase being such that the weight ratio R of: 1) the mass ratio, at a time t>; = 10 minutes, of the liquid fraction of the aqueous phase dispersed to the mass, at a time t>; = 10 minutes, of the liquid fraction of the continuous fatty phase measured according to the protocol defined in the description divided by 2) the ratio of the initial mass of the liquid fraction of the aqueous phase dispersed to the initial mass of the liquid fraction of the Continuous fat phase measured according to the protocol defined in the desc
