Abstract: The present invention relates to a cosmetic process which applies onto the skin a self-standing cosmetic sheet for the skin, comprising:
at least one biocompatible and/or biodegradable hydrophobic polymer layer
wherein
the self-standing cosmetic sheet has a thickness of from 10 to 1000 nm, preferably from 30 to 500 nm, and more preferably from 50 to 300 nm. The cosmetic sheet according to the present invention may comprise at least one cosmetic active ingredient.
The cosmetic sheet used in the present invention is very thin and not easily perceived on the skin; can be prepared with a variety of materials such as a biocompatible and/or biodegradable material; and can adhere well onto the skin without any adhesive layer so that it is less irritable or no irritable to the skin.-

Abstract: The present invention relates to a composition according to the present invention comprises: (a) at least one particle comprising at least one cationic polymer, at least one anionic polymer, and at least one hydrophilic or water-soluble UV filter; and (b) at least one physiologically acceptable volatile medium. The composition according to the present invention is stable, and can have a variety of cosmetic functions. For example, the composition according to the present invention can prepare a film which can have cosmetic effects such as UV filtering, as well as absorbing or adsorbing malodor, changing the appearance of a keratin substrate such as skin, changing the feel to the touch of the keratin substrate, and/or protecting the keratin substrate from, for example, dirt or pollutants.

Abstract: The present invention relates to a composite particle comprising: at least one hydrophilic core particle; and a plurality of hydrophobic particles, wherein the surface of the hydrophilic core particle is substantially discontinuously covered by the hydrophobic particles. The novel composite particle according to the present invention can have surface active properties sufficient to prepare stable Pickering emulsions, and can maintain the surface active properties over a long period of time. The present invention also relates to a method for preparing the above composite particle.
