- Patent Documents 1 to 3 are not sufficiently satisfactory in terms of feeling of use such as softness, moistness and smoothness compared to the resin beads described above. , there is a problem that the softness and smoothness peculiar to resin beads cannot be obtained.
- an object of the present invention is to provide an inorganic powder capable of imparting to cosmetics a feel, especially softness and smoothness, equivalent to or superior to that of resin beads.
- the present inventor focused on the fact that among the functions of resin beads, they have softness and smoothness and can be blended into the water-oil phase. Then, by surface-treating the base powder, which is mainly composed of inorganic materials, with a cationic surfactant and a higher alcohol, it imparts softness and smoothness, and is a substitute for resin beads that can be blended into the water-oil phase. is obtained.
- the composite surface-treated inorganic powder according to the present invention is obtained by surface-treating a base powder composed mainly of an inorganic material with a cationic surfactant and a higher aliphatic alcohol.
- the base powder mainly composed of an inorganic material has a layer in which the hydrophilic portion and the hydrophobic portion of the cationic surfactant and the higher aliphatic alcohol are arranged in parallel.
- the surface is treated with a multi-layer structure that is stacked alternately.
- the composite surface-treated inorganic powder according to the present invention preferably has an emulsion viscosity ratio of 3 or more and 30 or less.
- the emulsion viscosity ratio refers to the viscosity of the water phase obtained by adding 10 g of inorganic powder to 30 g of water and dispersing it at 3000 rpm for 3 minutes with a disper, and adding 10 g of hydrogenated polyisobutene to this water phase and dispersing it at 5000 rpm. It is expressed by the viscosity ratio of the emulsion obtained by emulsifying with a homomixer for 5 minutes.
- the emulsion viscosity ratio is 3 or more and 30 or less, it is possible to provide an amphipathic inorganic powder having excellent adhesion to the skin and excellent feel.
- the cationic surfactant is preferably a quaternary ammonium salt having a long-chain alkyl group with 8 to 26 carbon atoms.
- the cationic surfactant is preferably distearyldimethylammonium chloride.
- the higher aliphatic alcohol is preferably an alcohol having a long-chain alkyl group with 18 or more and 26 or less carbon atoms.
- the base powder preferably contains one or more selected from the group consisting of silica, titanium oxide, zinc oxide, alumina and iron oxide.
- the surface treatment amount of the cationic surfactant is 0.1 parts by mass or more and 6.0 parts by mass or less with respect to 100 parts by mass of the base powder. preferable.
- the surface treatment amount of the higher aliphatic alcohol is 0.5 parts by mass or more and 8.0 parts by mass or less with respect to 100 parts by mass of the base powder. is preferred.
- a cosmetic according to the present invention contains any of the composite surface-treated inorganic powders described above.
- a base powder mainly composed of inorganic materials is surface-treated with a cationic surfactant and a higher aliphatic alcohol.
- the base powder mainly composed of an inorganic material has a layer in which the hydrophilic portion and the hydrophobic portion of the cationic surfactant and the higher aliphatic alcohol are arranged in parallel.
- the surface is treated with a multi-layer structure that is stacked alternately.
- the inorganic material used as the base powder is not particularly limited, and for example, one or more selected from the group consisting of silica, titanium oxide, zinc oxide, alumina and iron oxide can be used. Among these, silica is particularly preferred.
- the base powder preferably has an average particle size of 0.1 ⁇ m or more and 50 ⁇ m or less, more preferably 0.3 ⁇ m or more and 30 ⁇ m or less, and more preferably 1 ⁇ m or more, as measured by a laser diffraction light scattering method. A range of 15 ⁇ m or less is more preferable. If the average particle size is less than 0.1 ⁇ m, the particles tend to aggregate together, which may hinder uniform surface treatment, making it difficult to improve the feel. be.
- the shape of the particles of the base powder may be any shape such as spherical, substantially spherical, hemispherical, spindle, needle, plate, polyhedral, and star-like, as long as they are those commonly used in cosmetics.
- a rounded shape such as a spherical shape, a substantially spherical shape, or a hemispherical shape is preferable.
- the particles of the base powder may be either nonporous or porous.
- the type of cationic surfactant is not particularly limited, it is preferable to use a quaternary ammonium salt having a long-chain alkyl group with 8 to 26 carbon atoms. Among these, those having two long-chain alkyl groups are more preferable.
- cationic surfactants include distearyldimethylammonium chloride, dialkyl(C12-C18)dimethylammonium chloride, lauryltrimethylammonium chloride, stearyltrimethylammonium chloride, cetyltrimethylammonium chloride, octadecyloxypropyltrimethylammonium chloride, and behenyl chloride. trimethylammonium, benzalkonium chloride and the like. Among these, it is particularly preferable to use distearyldimethylammonium chloride.
- the surface treatment amount of the cationic surfactant is preferably 0.1 parts by mass or more and 6.0 parts by mass or less, and 0.1 parts by mass or more and 2.0 parts by mass or less with respect to 100 parts by mass of the base powder. is more preferable.
- the amount of surface treatment is too small, the adhesion to the skin may not be good, and the cosmetic may easily come off after application. On the other hand, if the amount of surface treatment is too large, it may cause problems in terms of touch, such as stickiness when applied to the skin.
