The object of the present disclosure is a method for treating keratinous material, in particular human hair, involving applying the following to the keratinous material a first composition (A) comprising, relative to the total weight of the composition (A) (A1) less than 10% by weight of water and (A2) one or more organic C.sub.1-C.sub.6 alkoxy silanes and/or their condensation products, and a second composition (B) comprising (B1) Water, (B2) at least a first surfactant, and (B3) at least a second surfactant which is structurally different from the first surfactant (B2).

A water emulsion and film are provided comprising a polyacrylate random copolymer synthesized from acrylic acid (AA), butyl acrylate (BA), methyl methacrylate (MMA), and 2-ethylhexyl acrylate (EHA). The emulsion may be applied to a surface in liquid form, quickly drying to yield a peelable protective barrier film.

The present invention relates to a general process for treating keratin substances, preferably keratin fibres, comprising the following steps: c) applying to the keratin substances a composition comprising at least one photo-crosslinkable polymer including at least one photo-dimerizable pendant group and at least one hydrophobic pendant group, and d) irradiating said composition on the keratin substances to crosslink the polymer.

Provided herein are methods, compositions, and kits for coating or coloring keratinous fibers, such as human hair. In accordance with an exemplary embodiment, a method of coating mammalian hair includes (a) providing an oil phase that includes at least one reactive condensation-curable film-forming amino-silicone pre-polymer, (b) after subjecting said oil phase to a pre-treatment duration to obtain a pre-treated oil phase, emulsifying the pre-treated oil phase with an aqueous phase that includes water, so as to obtain a pre-treated oil-in-water emulsion, (c) applying, on an external surface of individual hairs of the mammalian hair, the pretreated oil-in-water emulsion, (d) after partial condensation curing of said pre-polymer of the pre-treated oil-in-water emulsion has occurred so as to form an at least partially cured amino-silicone coat on the external surface of the individual hairs, optionally washing the hair.

The invention relates to an aqueous cosmetic composition for care and maintenance of the hair comprising at least one setting resin, said resin comprising at least 20 mol % of a monomer unit of methacrylic acid and/or one of its salts; and optionally at least one monomer unit of acrylic acid and/or maleic anhydride, and/or one of their salts, the resin having a weight-average molecular weight greater than or equal to 20,000 g/mol. The invention also relates to the use of the setting resin for improving the resistance to humidity of these cosmetic compositions.

An article may be formed by contacting a 1,1-dicarbonyl substituted alkene with an activator comprised of an initiating salt and a weak acid and allowing the 1,1-dicarbonyl substituted alkene to cure to form the article. The article may be any useful shape such as a film, coating, layer (e.g., within an additive manufactured article), laminate or the like. The article may be one in which the cured article adheres substrates together.

An aqueous liquid cosmetic includes an inorganic coloring pigment, an anionic dispersant, and a film-forming polymer emulsion. The inorganic coloring pigment comprises a titanium black component having a primary particle size of 0.15 μm or more and at least one iron oxide component selected from the group consisting of red iron oxide, black iron oxide, and yellow iron oxide. Additionally, a content of the inorganic coloring pigment is 11 to 35% by mass based on a total amount of the cosmetic, and a content of the anionic dispersant is 8 parts by mass or less with respect to 100 parts by mass of a sum of the titanium black component and the at least one iron oxide component.

An oil-in-water emulsion cosmetic composition is provided. The cosmetic composition comprises a carboxylic acid modified silicone (A) that is liquid state at 50° C., an oil agent (B), water (C), and an oil-soluble film-forming agent (D). The oil-soluble film-forming agent (D) is present in a range of 0.01 to 5 mass % of the total mass of the cosmetic composition. The cosmetic composition according can provide a cosmetic film with high stability and excellent water resistance.

Disclosed herein are compositions that can be used to create a thin film on the skin of a subject in a single application step to the skin of the subject. More specifically, a composition provided herein does not have to be stored in multiple compartments, nor mixed with another composition or component before application to the skin. Instead, a single composition can be manufactured, stored in a single compartment, and then applied to the skin of a subject to create a film on the skin of the subject. In certain embodiments, because there is no need to mix a composition provided herein prior to application to the skin, the container comprising a composition provided herein may also include an applicator suitable for application of the composition to the skin.

A method for producing a film of the present invention includes the step of electrostatically spraying a liquid composition directly on the surface of skin using an electrostatic spray device to form a film on the skin. The electrostatic spray device includes a container capable of storing the liquid composition, a nozzle configured to eject the liquid composition, a power supply configured to apply a voltage to the nozzle, and a voltage stabilizer configured to stabilize the voltage applied by the power supply to the nozzle. The liquid composition contains component (a): one or more volatile substances selected from alcohols and ketones, and component (b): a polymer having film formability.
