• Such cosmetics often contain inorganic pigments and oils.
• powders that have not been surface-treated, especially powders that contain metal elements can act as catalysts in cosmetics and cause the cosmetic ingredients to deteriorate. For this reason, there is a need for surface-treated inorganic pigments.

• Cosmetics containing naturally derived ingredients are popular. Many pigments are used in makeup products for their aesthetic effect, but attempts have been made to stably blend inorganic pigments such as metal oxides by treating the surface with lipophilic substances. Other naturally derived ingredients include amino acid-treated pigments, which use amino acids amidated with carboxylic acids, and metal soap-treated pigments, which are made from higher fatty acids and alkaline earth metals.
• pigments that have been subjected to these surface treatments tend to have poor dispersibility in the polar oils commonly used in cosmetics.
• surface-treated pigments and the like aggregate the cosmetic product becomes dark in appearance, and its beauty is diminished.
• the present invention aims to improve the above situation, and its purpose is to provide a cosmetic composition in which the dispersibility of an inorganic pigment that has been surface-treated with an amide compound and/or its salt, or a metal soap, in a polar oil is improved.

Without being limited by theory, the mechanism is explained below.
• the inorganic pigment surface-treated by the above-mentioned (i) or (ii) there are still some parts on the surface where the hydrophilic groups are exposed, i.e., the hydrophilic surface is exposed. For this reason, there is a problem that the inorganic pigment surface-treated by the above-mentioned (i) or (ii) has poor dispersibility in the oil phase, particularly in liquid oils containing polar oil.

In these cases, the polyglyceryl-2 isostearate/dimer dilinoleic acid copolymer is thought to be used as a polar oil, not as a dispersant for inorganic pigments.

The lightness (L value) value of each of the prepared compositions was measured, and the lightness difference from the reference color was calculated. The results are shown in Table 6. Comparative Example 15 was used as the reference color.
• Example 18 showed improved dispersibility of component (A) compared to Comparative Example 15.
