Abstract
The invention relates to a film-forming composition comprising at least one aqueous dispersion of poly urethane particles and at least one plasticizer chosen from solvents having an average Hansen solubility parameter dH at 25.degree. C. such that dH.ltoreq.8 (J/cm.sup.3)1/2, and to its use in a process for making up keratin substances and/or mucous membranes. The invention also relates to the use of the aqueous dispersion of polyurethane particles and of the plasticizer to obtain a film-forming composition whose viscosity is stable over time and/or which does not solidify over time.
