Definitions

  • the present invention relates to a hydrophilic inorganic powder and a cosmetic containing the hydrophilic inorganic powder.
  • the cosmetics contain pigments and UV scattering agents based on zinc oxide, titanium oxide, etc. There is a desire to add this pigment and UV scattering agent to the aqueous layer of emulsifying cosmetics, but zinc oxide and titanium oxide themselves show strong cohesiveness, and have a powdery feel and physical irritation to the skin. Generally, surface treatment is performed.
  • a hydrophilizing agent for example, silica
  • zinc oxide having a surface coating of silica is an acid or acid to be added to cosmetics. It dissolves in alkali and zinc ions elute (see Reference 1). Therefore, in Reference 1, a first hydrophobic film is first formed on the surface of zinc oxide with a hydrophobizing agent (octylriethoxysilane), and then with a surfactant (emulsifier: PEG-11 methyl ether dimethicone). It forms a hydrophilic second coating (see Reference 1).
  • a hydrophobizing agent octylriethoxysilane
  • a surfactant emulsifier: PEG-11 methyl ether dimethicone
  • It forms a hydrophilic second coating see Reference 1).
  • Reference 2 describes a technique in which titanium dioxide is first hydrophobized with sodium stearate and then hydrophilized with isodecyl alcohol 6-ethoxylate and cetyl alcohol 10-ethoxylate. I
  • Cited Documents 1 and 2 a wide variety of combinations of the hydrophobizing agent and the hydrophilizing agent can be selected, but there is a problem that desired properties cannot be achieved depending on the combination thereof.
  • Cited Document 2 it is conceivable to acquire properties that could not be achieved by a single hydrophilization treatment agent by using two types of hydrophilization treatment agents in combination. There is no finding that can be used as an index for selecting a combination of agents.
  • a hydrophilized inorganic powder and the hydrophilized inorganic powder that have acquired properties that could not be achieved by a single hydrophilizing agent are blended by using two kinds of hydrophilizing agents in combination.
  • the purpose is to provide technology that contributes to the provision of cosmetics.
  • the present invention has an inorganic powder as a base material, a hydrophobic film covering the surface of the inorganic powder, and a hydrophilic film covering the hydrophobic film.
  • the composition of the hydrophilic coating comprises both a hydrophilic surfactant and a lipophilic surfactant.
  • Each of the hydrophilic surfactant and the lipophilic surfactant contains a branched alkyl moiety in a molecule to provide a hydrophilic inorganic powder having self-dispersability in a water or an aqueous solvent.
  • the hydrophilic film is a nonionic surfactant, which contains a branched alkyl moiety of C12-20 in the molecule.
  • the lipophilic surfactant preferably contains a branched alkyl moiety of C16 to 30 in the molecule.
  • the hydrophilic surfactant is one or more selected from the following group A. It is preferable that the lipophilic surfactant is one or more selected from the following group B.
  • the hydrophilic surfactant is preferably polyoxyethylene (10) isostearyl ether.
  • composition of the hydrophobic film is preferably one or more selected from dimethylpolysiloxane, disodium cocoyl glutamate, methylhydrogenpolysiloxane, stearic acid, silicone, and monoisostearyl sebacate.
  • a cosmetic containing a hydrophilized inorganic powder is provided.
  • a hydrophilized inorganic powder and the hydrophilized inorganic powder that have acquired properties that could not be achieved by a single hydrophilizing agent by using two kinds of hydrophilizing agents in combination.
  • the technology that contributes to the provision of cosmetics containing the above is provided.

  • FIG. 1 shows an example of the evaluation results of hydrophilicity and self-diffusion.
  • the inorganic powder is a powder that serves as a base for the hydrophilized inorganic powder, and is composed of particles of a metal oxide or metal hydroxide containing at least one of Ti, Zn, Si, Al, Fe, Mg, and Ce. Powder is preferred. Specific examples thereof include titanium oxide, zinc oxide, silica, aluminum oxide, iron oxide, iron hydroxide, magnesium oxide, and cerium oxide. Other oxides or hydroxides may be coated on these inorganic oxide powder particles.
  • the inorganic powder is not particularly limited as long as it is used for ordinary cosmetics. That is, the inorganic powder includes cericite, natural mica, calcined mica, synthetic mica, synthetic sericite, alumina, mica, talc, kaolin, bentonite, smectite, calcium carbonate, magnesium carbonate, magnesium silicate, aluminum silicate, Calcium phosphate, silicic anhydride, magnesium oxide, barium sulfate, magnesium aluminometasilicate, iron oxide, chromium oxide, titanium oxide, zinc oxide, cerium oxide, aluminum oxide, magnesium oxide, dark blue, ultramarine, calcium carbonate, magnesium carbonate, calcium phosphate , Aluminum hydroxide, magnesium sulfate, silicic acid, aluminum silicate magnesium silicate, calcium silicate, barium silicate, strontium silicate, silicon carbide, metal tungstate, magnesium aluminate, magnesium aluminometasilicate, chlorohydroxyaluminum,
  • the hydrophobic coating means a hydrophobic coating (also referred to as a hydrophobic first coating) that covers the surface of the powder, and in the present application, the inorganic powder covered with the hydrophobic coating is referred to as a hydrophobic inorganic powder.
  • a hydrophobic coating also referred to as a hydrophobic first coating
  • the inorganic powder covered with the hydrophobic coating is referred to as a hydrophobic inorganic powder.
  • the hydrophobic film is formed by an organic surface treatment agent, it can be said that the composition of the hydrophobic film is an organic surface treatment agent.
  • Hydrophobicity means, for example, that 100 cc of purified water is placed in a 200 cc glass beaker, and 0.2 g of powder collected in a spartel is dropped onto the water surface from a height of 2 cm above the water surface at a rate of twice per second. It means the property that the powder particles are suspended without migrating to the aqueous layer when the powder particles are allowed to stand for 30 seconds after being stirred 50 times using a spartel.
  • the organic surface treatment agent is an organic treatment agent for coating the surface of an inorganic powder to make it hydrophobic, and is also called a hydrophobic treatment agent.
  • the organic surface treatment agent include one or more compounds selected from silicone compounds, alkylsilanes, alkyltitanates, polyolefins, acylated amino acids, fatty acids, lecithins, ester oils, fructo-oligosaccharides, acrylic polymers, and urethane polymers.
