Solve the problems, such as: in order to provide O/W compositions, the infiltration for being modified to an active component of composition is preferably used for keratin substances, for example, skin composition O/W compositions.Solution: the present invention provides a cosmetic compositions in the form of oil-in-water (O/W) nano-emulsion, particularly, one skin care cosmetic compositions, there is the oil droplet as its particle diameter less than 100 nm to be dispersed in the oily phase in a water phase for it, for keratin substances, such as skin, cosmetic composition includes (a) at least one oil, (b) at least one active component, (c) water, (d) it is selected from nonionic surface active agent and anionic surfactant, and does not substantially include at least one surfactant of the water phase of water-soluble alcohols.Selected attached drawing: noneCopyright: (C) 2017, JPO& INPIT
