Abstract
The invention provides an oil-in-water emulsified cosmetic containing (a) an aqueous medium, (b) two or more higher fatty acids of 12 to 24 carbon atoms and alkali metal salts thereof, (c) at least one compound selected from the group consisting of monoalkyl glyceryl ethers having an alkyl group of 12 to 24 carbon atoms and monoalkenyl glyceryl ethers having an alkenyl group of 12 to 24 carbon atoms, (d) a thickener comprising (d-1) a polysaccharide derived from a microorganism and (d-2) a (meth)acrylic-based polymer selected from the group consisting of a poly(meth)acrylic acid salt and a polymer including at least one selected from the group consisting of a (meth)acrylic acid ester, a (meth)acryloylalkyltaurine and a salt thereof as a structural unit, and (e) a nonionic surfactant.
Claims2
An oil-in-water emulsified cosmetic comprising:
- (a) an aqueous medium,
- (b) two or more higher fatty acids of 12 to 24 carbon atoms or alkali metal salts thereof, selected from the group consisting of palmitic acid, stearic acid, behenic acid and their alkali metal salts thereof,
- (c) at least one monostearyl glyceryl ether,
- (d) a thickener comprising (d-1) xanthan gum and (d-2) a (meth)acrylic-based polymer selected from the group consisting of sodium polyacrylate, acrylates/C10-30 alkyl acrylate crosspolymer and acryloyldimethyltaurine ammonium/VP copolymer
- (e) a nonionic surfactant, that is a combination of glyceryl stearate and polyethylene glycol stearate, and
- (f) a ceramide,
- wherein the viscosity at 25° C. of said oil-in-water emulsified cosmetic is no higher than 2000 mPa·s, and
- wherein the content of component (b) ranges from 0.5 to 3 mass %, the content of component (c) ranges from 0.1 to 3 mass %, and the content of component (e) ranges from 1 to 4 mass %, based on the total mass, the content of component (f) ranges from 0.05 to 3 mass %, and
- wherein the content of the thickener ranges from 0.1 to 6 mass % based on the total mass, and
- wherein the content of the xanthan gum ranges from 0.1 to 2 mass % based on the total mass.
