A composition that includes an activatable aggregate is described herein. The aggregate has a core and a shell. In some embodiments, when the aggregate is exposed to acoustic energy, the core of the aggregate includes a hydrogel that is capable of absorbing a relatively large amount of water. The core of the aggregate is covalently bound to a shell of linear aliphatic moieties. The aggregate is synthesized to minimize the amount of water in the core, prior to exposure to acoustic energy. Methods of hydrating using the compositions are also provided.

An oral care composition is disclosed comprising calcium silicate and high refractive index particles wherein the calcium silicate and high refractive index particles are present in a relative weight ratio of 1110 to 511 and the surfaces of the high refractive index particles are substantially uncoated by calcium.

A cosmetic composition is provided herein. The cosmetic composition includes, relative to the total weight of the cosmetic composition, a) from about 2.0 to about 10 wt. % starch particles. The starch particles include, relative to the weight of the starch particles, a1) from about 65 to about 98 wt. % starch, and a2) from about 1.0 to about 30 wt. % pigment. The cosmetic composition further includes, relative to the total weight of the cosmetic composition, b) from about 2.0 to about 10 wt. % ethanol. The cosmetic composition further includes, relative to the total weight of the cosmetic composition, c) from about 80 to about 96 wt. % propellant.

Oily cosmetics which exhibit sufficient filling properties of viscosity and fluidity during the heating and melting steps of manufacture, significantly ameliorate the problems associated with the aggregation of powder, and have excellent usability characteristics, contain coated powder obtained by subjecting base material powder to composite treatment using at least alkylsilane and phospholipid through a wet method. The oily cosmetics contain 5 to 65 mass % of powder component, 0 to 40 mass % of solid oil, and 25 to 95 mass % of liquid oil, in which the content of the coated powder in the powder component is 0.1 to 65 mass % based on the total amount of the oily cosmetics.

There are described alkoxy-silanes compounds and related condensation products as cosmetic raw materials and for coating cosmetic powders; synthesis processes of such compounds and condensation products and production of coated cosmetic powders. Said cosmetic powders can be used for preparing cosmetic products such as anhydrous products for face/eyes/lips, cosmetic pencils and face/eyes emulsions.

According to the present invention, provided is a core-shell structured chromic microcapsule having a size of 50-1,500 m, comprising: a core comprising a colorant core (A) and an optional inner color layer (B); and a shell comprising a pressure sensitive destructible wall layer (C) encompassing the core, an optional outer color layer (D) and an optional outermost protective layer (E), wherein the colorant core allows a high content of a colorant to be contained, and the pressure sensitive destructible wall layer comprises carbon dioxide particles and a binder comprising one or more wall-forming materials and one or more lipid-base materials. The chromic microcapsule according to the present invention has high colorant content, has excellent storage durability, maintenance durability and color-hiding property of the inner color layers, is easily destroyed by pushing, rubbing, polishing or scrubbing with the hands or a tool (cotton fabric, sponge or paper) so as to express the color of the inner color layers, and can maintain stability for a long time even if being added into a carrier.

Disclosed is a cosmetic composition comprising: a) at least one UV filter; b) at least one SPF booster chosen from hollow particles, and/or at least one composite particle in spherical form, having a mean size of between 0.1 and 30 m comprising at least one particulate UV-screening agent and a core constituted of at least one inorganic material and/or of at least one organic material; c) at least one anti-oxidation active ingredient chosen from I) a compound according to formula (I) wherein each X independently represents OPO.sub.3Y, wherein Y is selected from hydrogen, Li, Na and K; II) a dimer peptide according to formula (II); III) a tocopherol or its derivatives; and IV) a mixture thereof.
