Abstract: Provided is a method for forming a coating comprising fibers having an excellent adhesivity to the skin, comprising directly electrostatically spraying on the skin.
A method for producing a coating comprising fibers on the surface of skin or nail, comprising directly electrostatically spraying onto human skin or nail, composition A comprising the following components (a), (b) and (c):
(a) one or more volatile substances selected from the group consisting of an alcohol and a ketone, (b) a water-insoluble polymer for fiber formation, (c) 0.2 mass % or more and 25 mass % or less of water; wherein the mass ratio of component (b) to component (c), ((b)/(c)) is of 0.4 or more and 50 or less.

Abstract: To provide a method for forming a transparent coating that is highly adherent to the skin and through which the skin is visible.
A method for forming a coating on a skin surface using a nanofiber sheet, the method comprising:
(1) Step (1) of applying to the skin a sheet transparentizing agent comprising 2 mass or more of one or more oil agents; and
(2) Step (2) of transferring a white nanofiber sheet mainly composed of a water-insoluble polymer to the skin after Step (1).

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.
