摘要:
The present invention is directed to an anti-fogging/anti-splash composition that can be used for anti-fog/anti-splash applications. When applied to the surface of a transparent or reflective substrate, the composition dries relatively clear and comprises a solution of a non-toxic, fast drying solvent or alcohol and a surface active agent containing sodium lauryl ether sulfate, and either a block ethylene oxide/polyethylene oxide copolymer, an ethoxylated amine, an ethoxylated acetylenic alcohol, sodium sulfosuccinate, ethoxylated sorbitan ester, random EO/PO polymers on butyl alcohol, or mixtures thereof. When applied to the surface of a substrate, the present invention provides a coating of high transparency which cures rapidly, is sufficiently surface active to be an anti-fog agent when “dry”, will persist when “wet” under water spray conditions (such as on a dental mirror) for a period substantial enough to be practicable, and will provide anti-splash benefits throughout the use cycle.
