The present invention provides a layered double hydroxide that exhibits selective adsorption of unsaturated fatty acids and has a pH in a neutral range (weakly acidic to weakly alkaline) when dispersed in water, and makeup using the layered double hydroxide. A fee was desired. The layered double hydroxide according to the present invention includes M (II) 1-X M (III) X (OH) 2 (where M (II) is one or two divalent metals. , M (III) is a trivalent metal, and x is 0.2 to 0.33), an intermediate layer intercalated between the basic layers, Interlayer water and the intermediate layer is R 1 —COOH or R 2 —SO 3 H (R 1 and R 2 are aliphatic hydrocarbon groups, substituted aliphatic hydrocarbon groups, aromatic hydrocarbon groups, substituted 1 or 2 or more types of substituents selected from an aromatic hydrocarbon group, a heterocyclic group, and a substituted heterocyclic group. |
