Provided is a cosmetic composition with excellent storage stability, feel during use and ultraviolet light blocking effects, in which an inorganic ultraviolet light blocking agent comprising a hydrophobic fine particulate metal oxide, e.g., hydrophobic fine particulate zinc oxide can be uniformly and stably dispersed in an aqueous phase, and in which a reduction in viscosity of a formulation is suppressed even when the structure of the hydrophobic fine particulate metal oxide is dispersed in the aqueous phase. The cosmetic composition comprises (A) a carboxylic acid modified silicone having a specific structure, (B) a water-soluble thickening agent, (C) a basic compound, and (D) a hydrophobic fine particulate metal oxide. The cosmetic composition is useful as a sunscreen cosmetic composition.

Cosmetic composition

A copolymer having excellent water resistance and sebum resistance while also exhibiting high washability is provided. Also provided is a composition and cosmetic material containing the copolymer. The copolymer is generally polymerized from a monomer composition comprising: (A) a carbosiloxane dendrimer monomer having a radically polymerizable organic group; and (B) an unsaturated monomer having at least one acidic group or a salt thereof per molecule; wherein monomer (A) is present in the monomer composition in an amount greater than or equal to 30 wt. % relative to the weight of the monomer composition, and a weight ratio (A/B) of monomer (A) to monomer (B) is from 1.0 to 20.0.

Copolymer having carbosiloxane dendrimer structure and acidic group, composition containing same, and cosmetic

A treatment agent for a cosmetic powder is provided. The treatment agent contains a reactive organosiloxane represented by the following general formula (1) as a main ingredient: In general formula (1): each Ris independently an alkyl group having 1 to 30 carbon atoms; each Ris independently an alkyl group having 1 to 20 carbon atoms; Ris a divalent alkylene group; n is an integer of 1 to 200; and p is an integer of 1 to 3. The treatment agent for a cosmetic powder of this disclosure is capable of imparting excellent lipophilicity. A cosmetic raw material having cosmetic effect and giving an excellent feeling of use, and a cosmetic are also provided.

Agent for treating powder for cosmetic, powder for cosmetic, and cosmetic formulated using said powder

A novel silicone surfactant comprises a co-modified organopolysiloxane copolymer having a long chain alkyl group, a polyether group, and a specific average polymerization degree of its siloxane back-bone. The silicone surfactant can be used for an emulsifier (especially for a water-in-oil (W/O) type emulsifier), a surface treatment agent, a powder treatment agent, or a dispersant in a cosmetic composition or a medicament. A W/O emulsion composition comprising the silicone surfactant; a powder composition where the surface of the powder is treated using the silicone surfactant as a powder treatment agent; a powder composition further comprising an oil agent and having a form of powder in oil dispersion; and a preparation for external use, particularly a cosmetic composition or medicament, comprising the same; are also disclosed.
