The invention relates to a process for treating keratin fibres, which comprises the application of a composition comprising: (a) one or more alkoxysilanes comprising solubilizing function(s) of formula R.sub.1Si(OR.sub.2).sub.z(R.sub.3).sub.x(OH).sub.y, and/or hydrolysis products thereof and/or oligomers thereof, (b) one or more alkylalkoxysilanes of formula (R.sub.4).sub.mSi(OR.sub.5).sub.n and/or hydrolysis products thereof and/or oligomers thereof, and (c) water in an amount of greater than 30% by weight relative to the total weight of the composition. The invention also relates to a composition comprising components (a), (b) and (c), and (d) one or more thickeners.

The present invention relates to a process for treating keratin materials, preferably human skin, in particular the lips, preferably in at least two steps involving, in a first stage, the application to said materials of an oily dispersion (A) comprising i) particles of copolymers of alkyl acrylates and of anhydride acrylics, ii) stabilizers, iii) one or more hydrocarbon-based oils; and then, in a second stage, the application to said materials of a composition (B) comprising iv) one or more amine compounds, it being understood that the process of the invention uses v) one or more cosmetic active agents chosen from a) pigments, b) active agents for caring for the skin, and c) UV-screening agents and also d) mixtures thereof; ingredients a) to d) possibly being found in composition (A), and/or in composition (B), and/or in another composition (C).

The process of the invention makes it possible to obtain a treatment of said keratin materials that is notably resistant to sweat, to shower gels, to water and to fatty substances, in particular plant or animal food oils, and more particularly plant oils such as olive oil, sunflower oil, walnut oil, hazelnut oil, etc.

The keratin material treatment process of the present patent application is also suitable for making up the skin or the lips, such as foundations and lipsticks.

Provided is a composition for forming a coating film containing fine fibers, imparting an excellent durability to an obtained coating film.

A composition for forming a coating film comprises the following components (a) and (b): (a) one or more oil agents selected from the group consisting of ester oil, ether oil, hydrocarbon oil and higher alcohol; and (b) a fiber, at 0.5 mass or more and 10 mass % or less based on the total composition for forming a coating film, the fiber having an average fiber diameter of 0.1 μm or more and 7 μm or less.

[(average fiber diameter).sup.2/(fiber content)]

(μm.sup.2/mass %) in the composition is 0.005 or more and 7 or less, and the mass ratio of the component (b) to the component (a), (b/a), is 0.005 or more and 5 or less.

A film coating for keratin fibers is described. The film coating is produced by applying to the keratin fibers a pretreatment composition and a film forming composition and curing the compositions to produce the film coating. The coating may be clear and function as a styling, conditioning and holding. The coating alternatively may contain pigment particles and provide a color coating.

The present disclosure provides a linkable cosmetic composition. The composition includes a vinyl pendant siloxane component and a hydrogen pendant siloxane component. The composition further includes a catalyst and a solvent.

A cosmetic kit includes a skin staining composition of (i) a monovalent salt of alginic acid, a water-soluble colorant, and water and (ii) an activating composition of water and a cosmetically acceptable salt of calcium or magnesium. Also disclosed is a method for cosmetically treating or making up the human skin by using the cosmetic kit useful in making up lips, eyelids and eyebrows.

The purpose of the present invention is to provide a hair treatment method that permits a suitable amount of a component having a hair treatment effect to be deposited uniformly on the hair, and that has exceptional persistence of effects in which hydrophobicity, combability, and smoothness is restored by appropriate heat treatment to hair that has been damaged and in which these effects can be maintained for an extended period of time. The present invention pertains to a hair treatment method characterized by including: (1) a step for applying, to hair, a hair treatment agent containing a copolymer that includes a polysiloxane structure and a polyoxyalkylene structure in the main chain, the copolymer having a side chain that has a trialkoxysilane group or a silanol group; (2) a step for subjecting the hair to heat treatment at 40-230° C.; and (3) a step for rinsing the hair.

A method for treating keratinous material, in particular human hair, is disclosed. The method comprises applying to the keratinous material a first composition (A) and a second composition (B). The first composition (A) comprises (A1) less than about 10% by weight of water, and (A2) one or more organic C1-C6 alkoxy silanes and/or their condensation products. The second composition (B) comprises (B1) water, and (B2) one or more alkylene glycols of a particular formula (AG-I). A multi-component packaging unit (kit-of-parts) comprising the first composition (A) and the second composition (B) is also disclosed.
