Description

This invention relates to a solid powder makeup cosmetic composition and a method for producing a solid powder makeup cosmetic composition. There are generally two methods for manufacturing solid makeup cosmetics: dry molding and wet molding. Dry molding involves mixing powder and oil and then applying pressure during the molding process. This method is simple and widely used. The wet molding method is a method of preparing cosmetics by adding a solvent to a cosmetic base containing powder and oil, forming a slurry, filling it into a container, and then removing the solvent. Cosmetics prepared by this molding method tend to have a smooth texture. Organic solvents or water are used as the solvent. Japanese Patent Publication No. 2022-109179 This figure shows the manufacturing flow of solid powder eyeshadow in the example. The present invention will be described in detail below. In this specification, unless otherwise specified, the notation "a to b" for numerical values a and b is equivalent to "a or greater and b or less." That is, the notation "a to b" includes both numerical values a and b. If a unit is attached only to numerical value b in such notation, that unit shall also apply to numerical value a. 《Oil-based ingredients; component A》 The composition of the present invention comprises one or more oily agents. The oily agent comprises at least one ester oil (component A1) selected from the group consisting of dimer acid esters and polyhydric esters, and a polyhydric alcohol (component A2). Dimer acid esters refer to esters of dimer acids obtained by polymerization of two molecules of unsaturated fatty acids. Examples of unsaturated fatty acids include linoleic acid, linolenic acid, and oleic acid. Examples of esters of these dimer acids include higher alcohols such as isopropyl alcohol, cetyl alcohol, oleyl alcohol, stearyl alcohol, isostearyl alcohol, behenyl alcohol, lauryl alcohol, and linoleyl alcohol; dimer ols, which are obtained by polymerization of two molecules of unsaturated alcohols such as dimer linoleyl alcohol; dimer esters, which can be derived from phytosterols, and castor oil. Specifically, examples of dimer acid esters include dimer dilinoleyl bis(behenyl/isostearyl/phytosteryl) dimer dilinoleate, dimer dilinoleic acid (phytosteryl/isostearyl/cetyl/stearyl/behenyl), dimer dilinoleyl bisstearyl dimer dilinoleate, hydrogenated castor oil dimer dilinoleate, and diisopropyl dilinoleate. Examples of polyvalent esters include diesters, triesters, and tetraesters. Examples of diesters include diesters of dicarboxylic acids having 3 to 18 carbon atoms, and di-fatty acid esters of polyhydric alcohols. Specific examples include propylene glycol dicaprylate, neopentyl glycol dicaprate, glycol distearate, propylene glycol diisostearate, glyceryl diisostearate, glyceryl monomyristate monoisostearate, glyceryl di-2-heptylundecanoate, di-2-ethylhexyl succinate, diisopropyl sebacate, diisostearyl malate, ethylene glycol di-2-ethylhexanoate, diisobutyl adipate, di-2-heptylundecyl adipate, and di-2-ethylhexyl sebacate.

The content of component A1 can be, for example, 1 to 20% by weight, 2 to 18% by weight, or 3 to 10% by weight, based on the total amount of the composition. The content of component A1 can be, for example, 20-80% by weight, 25-70% by weight, or 30-60% by weight according to the oil standard.
