摘要： [Problem]
To provide a cosmetic composition with excellent storage stability, feel during use and ultraviolet light blocking effects, in which an inorganic ultraviolet light blocking agent containing a hydrophobic fine particulate metal oxide as represented by 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.
[Resolution Means]
A cosmetic composition containing an inorganic ultraviolet light blocking agent that contains (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. Particularly, a use as a sunscreen cosmetic composition.-

摘要： [Problem]
An object of the present invention is to provide: a co-modified organopolysiloxane that has excellent affinity and compatibility with a wide range of cosmetic product raw materials (particularly non-silicone oil agents such as fatty acid ester oils and the like), is less likely to cause thickening or inferior dispersion when used with powders, and can form favorable and stable slurries; and a use thereof.
[Resolution Means]
A co-modified organopolysiloxane expressed by the following structural formula (1), with an HLB value within a range of 0.5 to 2.0 and viscosity within a range of 200 to 1500 mPa s, as well as a use thereof as a powder dispersing agent or the like. R 2 is a monovalent hydrocarbon group having 6 to 30 carbon atoms, L 1 is an organosilicon-containing organic group selected from silylalkyl groups having a carbosiloxy dendron structure and groups having a siloxane macromonomer structure, and Q is a hydrophilic group, which is a (poly)glycerin residual group or sugar alcohol residual group}.-

摘要： The present invention relates to an oil-in-water cleansing cosmetic composition, containing: (A) carboxylic acid-modified silicone that is liquid at 50°C; (B) 3 to 80 mass% of an oil agent relative to the total mass of the cosmetic composition; (C) water; and (D) a basic compound; where an amount of an ionic surfactant other than the carboxylic acid-modified silicone (A) that is liquid at 50°C is 10 mass% or less relative to the total mass of the cosmetic composition. The cleansing cosmetic composition according to the present invention quickly blends with makeup grime, has a high makeup removing effect, and has excellent stability.
