Abstract: Provided is a method for forming a good fibrous coating on a target surface even in a high-humidity environment when electrostatically spraying is performed directly on the target surface such as skin.
A composition for forming a coating of fibers on a target object by electrostatic spraying, comprising the following components (a), (b), (c) and (d): (a) 1 mass % or more and 45 mass % or less of a polymer having a film-forming ability; (b) 45 mass % to 95 mass % of one or more volatile substances selected from the group consisting of an alcohol and a ketone; (c) a conductivity controlling agent to control the conductivity of the composition to 8 μS/cm or more and 300 μS/cm or less; and (d) 0.2 mass % or more and 25 mass % or less of water.

Abstract: A method for forming a coating on a skin surface using a nanofiber sheet, the method including: (1) applying to the skin a sheet transparentizing agent containing 2 mass % or more of one or more oil agent; and (2) transferring a white nanofiber sheet mainly composed of a water-insoluble polymer to the skin after (1), where the transferred white nanofiber sheet becomes transparent and the coating is a transparent coating through which the skin is visible.
