Glycerin dispersion and cosmetic
Provided are: a glycerin dispersion in which the dispersibility and storage stability of a hydrophobized inorganic powder are improved; and a cosmetic containing the glycerin dispersion. A glycerin dispersion containing a hydrophobized inorganic powder, in which an inorganic powder is used as a base and hydrophobicity is imparted by coating the inorganic powder with an organic surface treatment agent, a polyglycerin-based nonionic surfactant, and glycerin is provided.
1 . A glycerin dispersion, comprising:
a hydrophobized inorganic powder, in which an inorganic powder is used as a base and hydrophobicity is imparted by coating the inorganic powder with an organic surface treatment agent;
a polyglycerin-based nonionic surfactant; and
glycerin;
wherein an alkyl group in the polyglycerin-based nonionic surfactant has 10 to 14 carbon atoms, and the content of the hydrophobized inorganic powder is 50 wt % or more.
2 . The glycerin dispersion according to claim 1 wherein the organic surface treatment agent is one or more types of compounds selected from a silicone compound, an alkyl silane, an alkyl titanate, an acylated amino acid, a fatty acid, lecithin, an ester oil, an acrylic polymer, and a urethane polymer.
3 . A cosmetic, comprising the glycerin dispersion according to claim 1 as an aqueous layer component.
4 . A cosmetic, comprising the glycerin dispersion according to claim 2 as an aqueous layer component.
