摘要:
A cosmetic composition includes an aqueous phase (>;=5 wt.%) of a dispersed solid phase and a liquid fatty phase having non-volatile fraction(s). The liquid fatty phase comprises at least two oils from slow volatile oils with an evaporation rate of 0.002-0.05 mg/cm 2>;/minute and dry oils from oils with a viscosity of =10 cPs, a surface tension of 21-31 mN/m and an evaporation rate of less than 0.002 mg/cm 2>;/minute. A cosmetic composition comprises an aqueous phase (>;=5 wt.%) of a dispersed solid phase and a liquid fatty phase having non-volatile fraction(s). The liquid fatty phase comprises at least two oils from slow volatile oils with an evaporation rate of 0.002-0.05 mg/cm 2>;/minute and dry oils from oils with a viscosity of =10 cPs, a surface tension of 21-31 mN/m and an evaporation rate of less than 0.002 mg/cm 2>;/minute. The liquid fatty phase has an evaporation rate such that the weight ratio of the liquid fatty phase after 10 minutes of drying, to the initial liquid fatty phase, is 0.75-1. The aqueous phase and the liquid fatty phase are such that the weight ratio (R) of the ratio of the mass, at a time (t)=10 minutes, of the liquid fraction of the dispersed aqueous phase to the mass, at a time (t)=10 minutes, of the liquid fraction of the continuous fatty phase divided by the ratio of the initial mass of the liquid fraction of the dispersed aqueous phase to the initial mass of the liquid fraction of the continuous fatty phase, is =1.
