There are provided a porous pad for the impregnation of a liquid cosmetic composition and a liquid-cosmetic-composition impregnating method using such a porous pad. The porous pad includes a first porous pad layer and a second porous pad layer. An injection hole is formed in the first porous pad layer for the injection of the liquid cosmetic composition. The second porous pad layer is disposed under the first porous pad layer, and has a dispersion hole for the dispersion of the liquid cosmetic composition that is injected through the injection hole, and one or more main storage holes that are radially arranged around the periphery of the dispersion hole.

The present application relates to a hybrid foam including a hybrid copolymer of polyether polyol and polyester polyol, and to a cosmetic kit including the hybrid foam.

The present invention relates to a cosmetic comprising an acrylonitrile-butadiene rubber (NBR) as a carrier of a cosmetic composition and, specifically, to a cosmetic comprising a foam carrier and a cosmetic composition loaded on the foam carrier, wherein the foam carrier contains an NBR, includes pores with an average size of 200-900 m, and has a thickness of 1-50 mm, and wherein the cosmetic composition has a viscosity of 2,000-60,000 cps. The present invention has excellent filling ability, loading ability, and discharging ability with respect to the liquid-phase cosmetic composition, and thus facilitates carrying a liquid-phase cosmetic composition with low viscosity to high viscosity.

A multilayer beauty care product or method is provided. The beauty care product has a water soluble film zone that includes a water soluble film forming polymer and a cosmetic composition with an effective amount of a skin active agent. The product also has a barrier patch having a backing layer and a pressure sensitive adhesive zone. The adhesive zone and the water soluble film zone are continuous, discontinuous, or a combination thereof. The product exhibits a dynamic modulus.

The instant disclosure relates to an integral porous fiber media with distinguishable distribution of fiber density, fiber diameter and capillary force. The instant disclosure further relates to a fiber porous media that includes multiple density portions. The disclosed media is a single piece, such that the different density portions are not separable. The disclosed media provides improved liquid delivery properties for a specific liquid delivery device.

A method for producing a cosmetic puff using a membrane film and a cosmetic puff, the cosmetic puff being produced through the steps of: forming a liquid cosmetic material storage part of which an inner skin has at least one surface thereof made of a membrane film; filling a liquid cosmetic material into the liquid cosmetic storage part; covering the entire outer surface of the inner skin or the inner skin top surface with a porous cushion material; and covering the outer surface of the inner skin or the cushion material with an outer skin. The cosmetic puff allows a liquid cosmetic material to be discharged to the outside of the puff merely by pressure during use, provides the effect of moisturizing and astringing skin, thereby prevents the skin from becoming dry, and, at the same time, has the effect of preventing outside contents or bacteria from penetrating the inside.
