Abstract
The present disclosure provides a water-in-oil makeup cosmetic composition containing isostearic acid, a pigment-grade powder (specifically, a pigment-grade powder coated with a lipoamino acid), an emulsifier having an HLB greater than 0 and lower than or equal to 8, and a residual amount of water, the composition having superior water resistance and cleansing properties at the same time. The water-in-oil makeup cosmetic composition of the present disclosure can be usefully used because it has superior water resistance in environments with below-neutral pH, such as tap water, sweat, etc. and is converted to have superior cleansing properties when the skin is washed with alkaline water such as soapy water.
