US Patent No. 10,105,291 B2; Amorepacific Corp., Seoul, has patented a cosmetic that is comprised of a foam impregnated with a cosmetic composition and an applicator onto which the cosmetic composition is ejected.
The foam comprises one or more material selected from a group consisting of acrylonitrile-butadiene rubber (NBR), styrene-butadiene rubber (SBR), natural rubber (NR), polyvinyl chloride, polyethylene, ethylene-vinyl acetate (EVA), latex, silicone, film-type, styrene-isoprene-styrene (SIS), styrene-ethylene-butylene-styrene (SEBS), polyvinyl alcohol (PVA), silicone elastomer, nitrile, butyl and polyether and neoprene; and an applicator onto which the cosmetic composition is ejected.
Acrylonitrile-butadiene rubber (NBR), styrene-butadiene rubber (SBR) and natural rubber (NR) is selected when the foam is used for improving skin adhesion of a cosmetic composition. Polyvinyl chloride, polyethylene and ethylene-vinyl acetate (EVA) is selected when foam is used for reducing skin roughness of a cosmetic composition. Latex, silicone, film-type, styrene-isoprene-styrene (SIS), styrene-ethylene-butylene-styrene (SEBS), polyvinyl alcohol (PVA), silicone elastomer, nitrile, butyl, polyether and neoprene is selected when the foam is used for improving skin texture of a cosmetic composition.
The cosmetic composition is an aqueous dispersion, an oily dispersion, a water-in-oil (W/O) emulsion or an oil-in-water (O/W) emulsion.
