Abstract
The present invention provides a skin cosmetic containing the following components (A), (B), (C), (D), (E), and (F): (A) 0.5 to 6 mass % of a linear saturated fatty acid having 12 to 22 of carbon atom, (B) 0.010 to 5 mass % of an organic base, (C) 0.010 to 1 mass % of an inorganic base, (D) 0.5 to 6 mass % of a linear saturated alcohol having 12 to 22 of carbon atom, (E) 0.05 to 9 mass % of a powder, and (F) water, wherein the component (D) comprises at least a linear saturated alcohol having 12 to 20 of carbon atom, and the mass ratio of the component (E) to the total amount of the components (A) and (D) [(A)+(D)] is (E)/[(A)+(D)]=from 0.01 to 5.
