Composition for coating film with specific components and properties
A patent application (Publication Number: US20240033204A1) discloses a composition for forming a coating film, comprising a polymer with coating film forming ability, volatile substances like alcohols and ketones, a plasticizer, and a non-volatile oil agent with specific viscosity characteristics. The composition allows for the formation of a coating film on skin fibers when applied directly using an electrostatic spray method. The non-volatile oil agent can be selected from various options like ester oils, silicone oils, and hydrocarbon oils, among others, with specific viscosity ranges to achieve the desired coating film properties.
Additionally, the patent application includes a sheet-like composition for skin obtained by electrostatically spraying a similar composition with a polymer, volatile substances, plasticizer, and non-volatile oil agent. The non-volatile oil agent in this composition can also be selected from a range of options like glycerin difatty acid esters, liquid paraffins, and vaselines. The composition aims to provide a method for forming a coating film on the skin, offering specific content mass ratios of the components to achieve the desired film-forming properties. The patent application also details a composition with specific mass percentages of the components, including the polymer, volatile substances, plasticizers, and non-volatile oil agents, to ensure the effectiveness of the coating film formation process.
