The present invention relates to preventing color transfer and sticking of powder-containing cosmetics to clothes or the like. A coating formation method of the present invention includes an electrostatic spraying step of electrostatically spraying a composition directly onto a skin surface onto which powder-containing cosmetics have been applied, thereby forming a coating on the skin. The composition contains a component (a) and a component (b) below. It is preferable that the method further includes a liquid agent applying step of applying a liquid agent containing one or more selected from water and oils that are in liquid form at 20&#xb0; C. on the skin onto which the powder-containing cosmetics have been applied, wherein the liquid agent applying step is performed subsequent to the electrostatic spraying step. (a) One or more volatile substances selected from water, alcohols, and ketones; and (b) a polymer having a coating formation ability.

Method for producing coating film by electrostatic spraying

Methods for producing a cosmetic coating on a skin surface, by: (A) electrostatically spraying a composition comprising component (a) one or more volatile substances selected from the group consisting of water, an alcohol and a ketone, and component (b) a polymer having a film-forming ability directly onto the skin to form a coating on the skin surface; and (B) subsequently applying a powder-containing cosmetic on the formed coating, afford cosmetic coatings which can be removed without using a cleansing agent.

Method for producing cosmetic coating

A nanofiber laminate sheet including a layer of a nanofiber of a water insoluble polymer and a layer of a water soluble polymer containing a cosmetic component or a medicinal component. The nanofiber is preferably colored. The layer of a water soluble polymer is preferably a layer of a nanofiber of the water soluble polymer containing the cosmetic component or the medicinal component. The nanofiber laminate sheet is suited for use as a cosmetic sheet for makeup.
