Disclosed is an oxidizer-free method for providing semi-permanent curl to eyelashes, and a kit for use with the method. The method involves a three-step process: (i) applying a first composition that includes a reducing agent to an eyelash, (ii) applying a second composition that includes a contractile polymer to the eyelash, and (iii) manually lifting the eyelash. Unlike conventional lash lifting techniques, the disclosed method requires no glue, silicone pads, compositions with oxidizing agents, or heating.

Disclosed are compositions for treating and conditioning keratinous substrates, comprising a cationic agent comprising quaternary ammonium compounds; a modified starch; silane compounds, a cationic vinylpyrrolidone polymer and water. Also disclosed are methods treating and conditioning keratinous substrates using the composition.

A method for applying a cosmetic composition to skin is disclosed. The method can include applying a first composition to skin that includes at least about 50% by weight of a volatile hydrocarbon, a film former, a solvent comprising an ester group, and a combination of ultraviolet A (UVA) and ultraviolet B (UVB) sunscreen agents, wherein the UVA sunscreen agent comprises 4-tert-butyl-4′-methoxydibenzoylmethane, wherein the first composition has an SPF of at least about 15 and a PFA of at least about 5, and wherein the first composition dries within two minutes after topical application to skin, and subsequently applying the cosmetic composition onto the first composition.

Described herein are oral care compositions comprising a crosslinked polyvinylpyrrolidone complexed with hydrogen peroxide, together with particular co-polymers as additional excipients; including some embodiments which further comprise a calcium abrasive.

A water-in-oil emulsion composition comprising (a) water, (b) at least one oil, (c) at least one surfactant, (d) at least one water-soluble vinyl polymer, and (e) at least one organosiloxane film-former that is selected from a silicone resin and a random acrylic/silicone graft copolymer is provided. The composition may be a composition for eyelashes, for example a mascara composition further including at least one colorant.

Provided are compositions comprising an orally-acceptable carrier and a cationic copolymer derived from the polymerization of n-vinyl pyrrolidone (VP) with cationic monomers containing amines or by copolymerization of n-vinyl pyrrolidone (VP) monomers with cationic monomers comprising amides followed by deprotection to amines. Also provided are uses of such compounds in the oral cavity to inhibit demineralization of a tooth.

Provided are compositions comprising an orally-acceptable carrier and an anionic copolymer derived from the polymerization of n-vinyl pyrrolidone (VP) with an anionic monomer compound containing phosphorus. Also provided are uses of such compounds in the oral cavity to inhibit demineralization of a tooth.

The present disclosure provides tooth whitening oral care compositions comprising potassium peroxymonosulfate having improved stability, and methods of using the same.

A composition contains at least one sunscreen and a protein-PVP copolymer. The sunscreen may be organic and/or inorganic, particularly titanium dioxide. The protein-PVP copolymer improves the effectiveness of the sunscreen, resulting in increased SPF values of the composition.

The present invention concerns a substrate-based product comprising a water-insoluble substrate, at least one chemical exfoliator, and at least one skin binding agent, its method of preparation and its cosmetic uses.
