Various embodiments disclosed relate to water-based nail-treatment compositions including a first film-forming copolymer that is a copolymer of a (C.sub.1-C.sub.5)alkyl ester of methacrylic acid, of a (C.sub.1-C.sub.5)alkyl ester of acrylic acid, or a combination thereof, and of methacrylic acid. The nail-treatment compositions also include a second film-forming copolymer that is a copolymer of isophorone diisocyanate, a poly((C.sub.2-C.sub.3)alkylene oxide), and 2,2-bis(methylol)propionic acid. Methods of using the nail-treatment compositions and cured products of the same are also provided. A cured product of the nail-treatment composition can be monolithically peelable from the nail.

The present invention discloses a unidirectional moisturizing nanofiber facial mask substrate with asymmetric wettability and preparation thereof. The preparation includes: preparing a superhydrophilic electrospun fiber membrane on a substrate by electrospinning; preparing a hydrophobic electrospun fiber membrane by electrospinning on a lateral surface of the superhydrophilic electrospun fiber membrane away from the substrate to form a double-layered membrane; and removing the substrate, and drying the double-layered membrane to obtain the asymmetric unidirectional moisturizing facial mask substrate with one side being superhydrophilic and the other side being hydrophobic. The superhydrophilic layer can absorb a nutrient solution and be applied to the skin surface, while the hydrophobic layer can keep itself dry, reduce the consumption of the nutrient solution and inhibit volatilization of the nutrient solution. The process is simple, uses readily available materials, and is non-toxic, environmentally friendly, and low-cost, thus solving several key problems with current commercial facial mask substrates.

The invention provides a cosmetic base having an unprecedented appearance and feeling on use, in particular a cosmetic base with a novel feeling on use that gives a fresh feeling and a unique feel as the cosmetic softly bursts and collapses, allowing water to flow out, when applied to the skin, and a skin cosmetic using the same. A cosmetic base includes (A) 0.15-0.6 mass % of sodium acrylate-grafted starch and (B) 0.25-1.35 mass % of an associative thickener having a polyoxyalkylene chain wherein the total amount of the (A) sodium acrylate-grafted starch and (B) associative thickener having a polyoxyalkylene chain compounded is 0.5-1.5 mass % and to a skin cosmetic that uses the cosmetic base.
