Disclosed is a microcapsule comprising: (i) a core comprising a benefit agent; and (ii) a shell comprising silica; wherein said shell comprises plate-like inorganic materials having an average thickness of 1-1000 nm; wherein said benefit agent is fragrance, pro-fragrance, hair conditioning agent, anti-dandruff agent, moisturizers, emollients, dyes and/or pigments, colour care additives (including dye fixing agents), or a mixture thereof.

A method for coloring keratinous material, in particular human hair, includes the step of applying on the keratinous material: a first composition (A) comprising: (A1) one or more organic C.sub.1-C.sub.6 alkoxysilanes and/or condensation products thereof, and (A2) at least one colorant compound selected from the group comprising pigments and direct dyes, and a second composition (B) comprising (B1) a copolymer of styrene and maleic acid (anhydride).

Providing a cosmetic having a smooth after-feel even if the cosmetic contains a high proportion of oil. A cosmetic includes (A) a starch powder, and as oils, (B) a polar oil and (C) a volatile oil. The ratio of (C) the volatile oil to (B) the polar oil being 0.5 or higher.

Provided is an oil powder foundation which utilizes advantageous features of a powder foundation and an oil foundation and has solved problems that these foundations have, and which gives natural finish having high hiding power. The oil powder foundation may include (a) spherical particles, (b) titanium dioxide, (c) a film-forming agent, (d) a volatile oil agent, and (e) a surfactant. Using a urethane powder, acrylic powder, nylon powder, silicone powder, cellulose powder, silica powder, or calcium carbonate powder having an average particle diameter of 5 to 20 μm as the component (a), the oil powder foundation is prepared so that the total of the component (a) and the component (b) is contained in an amount of 35 to 55% by mass and the mass ratio of the component (a) and the component (b) is 1 to 1.5:1.5 to 1.

The present invention relates to a cosmetic composition for the treatment of keratin fibres, particularly human keratin fibres such as hair, comprising, in a cosmetically acceptable medium, one or more organosilanes, one or more cationic polymers having charge density greater than or equal to 4 meq/g and one or more cationic surfactants. The present invention also relates to a cosmetic process for treating keratin fibres using said cosmetic composition. The present invention finally relates to the use of said composition for the cosmetic treatment of keratin fibres.

A coated powder comprises (a) particles, and (b) a coating on the surface of the particles including (1) silica moieties, (2) organo oxysilane moieties selected from the group consisting of mono-organo oxysilane moieties, bi-organo oxysilane moieties and tri-organo oxysilane moieties, and (3) poly(dialkyl)siloxane moieties. The amount by weight in SiO.sub.2 equivalents of the organo oxysilane moieties and the silica moieties is at least 0.0625% of the total coated powder weight per m.sup.2/g of the specific surface area of the particle to be coated.

The present invention relates to a composition for preventing or treating scars and a preparation method therefor. The composition, according to one aspect, comprises a pigment and silicone oil, and may be stably formulated into a formulation adequate for spreading on the skin, and may inhibit the formation of scars or reduce already existing scars by forming a membrane on the skin, and has an effect whereby scars may be concealed by the pigment stably dispersed in the composition.

The present disclosure relates to a skin film forming agent, and provides a skin film forming agent which comprises dimethiconol, hydride dimethicone and a cross-linking component, and thereby provides a skin film forming agent which has no problem of safety, and forms a film with high intensity, and thereby can solve peeling and slipping of the film and effectively improve skin disadvantages, particularly, wrinkles and elasticity.

A process for dyeing keratinous material is disclosed. The process includes applying an agent (a) and an agent (b) to the keratinous material. The agent (a) comprises (a1) at least one organic silicon compound, and (a2) at least one sulfated and/or sulfonated fatty acid ester. The agent (b) comprises (b1) at least one sealing reagent, and (b2) at least one first colorant compound. A multi-component packaging unit is also disclosed, and comprises, separately packaged, a first container comprising an agent (a′), a second container comprising an agent (a″), and a third container comprising an agent (b). The agent (a′) comprises (a1) at least one organic silicon compound. The agent (a″) comprises (a2) at least one sulfated and/or sulfonated fatty acid ester. The agent (b) comprises (b1) at least one sealing reagent, and (b2) at least one first colorant compound.

The present disclosure relates to silica particles comprising repeating units of (SiO.sub.4/2) that are spherical in shape, which has the benefit of compatibility with personal care components and the resulting personal care applications. The present disclosure also relates to methods of preparing silica particles.
