Water-based cosmetic and manufacturing method thereof

A method of producing a water-based cosmetic comprising:

• (A) ceramidic compound-containing particles that include a ceramidic compound and that are dispersed as an oil phase in an aqueous phase;
• (B) a fatty acid component composed of at least one selected from the group consisting of fatty acids and fatty acid salts;
• and
• (C) a polyhydric alcohol component that includes a first polyhydric alcohol having an IOB of 2.2 or more and a total content in the water-based cosmetic of from 3% by mass to 20% by mass, and a second polyhydric alcohol having an JOB of 2.0 or less and a total content in the water-based cosmetic of 0% by mass or not more than 3% by mass,
• wherein the ceramidic compound is selected from the group consisting of ceramide 1, ceramide 9, ceramide 4, ceramide 2, ceramide 3, ceramide 5, ceramide 6, ceramide 7, ceramide 8 and ceramide 3B,
• the fatty acid component is selected from the group consisting of lauric acid, oleic acid, isostearic acid α-linolenic acid, γ-linolenic acid, and salts thereof,
• the first polyhydric alcohol is selected from the group consisting of propylene glycol, glycerin, and 1,3-butyleneglyco-diglycerin,
• the second polyhydric alcohol is selected from the group consisting of isoprene glycol, dipropylene glycol, ethoxy diglycol (diethylene glycol monoethyl ether), penthylene glycol, and hexylene glycol, and
• the total content of surfactant in the water-based cosmetic is 0% by mass or not more than 1% by mass, and the total mass of the ceramidic compound in the water-based cosmetic is at least 3.0 times the total mass of the fatty acid component,
• said method comprising the steps of:
• mixing an oil phase component that includes at least a ceramidic compound, and an aqueous phase component, at a temperature of 40° C. or lower, to obtain a ceramide dispersion that includes a polyhydric alcohol component in the aqueous phase component;
• and
• mixing the ceramide dispersion and an aqueous composition.
