Abstract
The present invention relates to a foam made of a specific material having superior properties and to cosmetics comprising said foam.
Claims11
A cosmetic comprising:
- one or more of a foam impregnated with a cosmetic composition for storing the cosmetic composition, wherein 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;
- the cosmetic composition impregnated in the foam;
- and
- an applicator onto which the cosmetic composition is ejected,
- wherein the one or more material is selected from a group consisting of acrylonitrile-butadiene rubber (NBR), styrene-butadiene rubber (SBR) and natural rubber (NR) when the foam is used for improving skin adhesion of a cosmetic composition;
- wherein the one or more material is selected from a group consisting of polyvinyl chloride, polyethylene and ethylene-vinyl acetate (EVA) when the foam is used for reducing skin roughness of a cosmetic composition;
- wherein the one or more material is selected from a group consisting of latex, silicone, film-type, styrene-isoprene-styrene (SIS), styrene-ethylene-butylene-styrene (SEBS), polyvinyl alcohol (PVA), silicone elastomer, nitrile, butyl, polyether and neoprene when the foam is used for improving skin texture of a cosmetic composition;
- and
- wherein the cosmetic composition is an aquious dispersion, an oily dispersion, a water-in-oil (W/O) emulsion or an oil-in-water (O/W) emulsion.
6 more elements
A method of improving adhesion of a cosmetic composition to skin comprising
- ejecting a cosmetic composition from a carrier foam onto an applicator, wherein the cosmetic composition is stored within the carrier foam and the carrier foam comprises one or more material selected from the group consisting of acrylonitrile-butadiene rubber (NBR), and styrene-butadiene rubber (SBR), polyvinyl chloride, latex, and polyether, and wherein the cosmetic composition is in a liquid or cream state, wherein 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;
- and
- applying the ejected cosmetic composition to skin to achieve improved adhesion of the cosmetic composition to the skin.
