Abstract

PROBLEM TO BE SOLVED: To obtain a cosmetic and a preparation for external use, capable of suppressing oily feeling, capable of providing a smooth-touch and light feeling, having air-permeability and moist feeling, capable of retaining moisture, and further having emollient properties and a specific feeling by including a specific ester as an oil phase component. SOLUTION: This cosmetic and preparation for external use contain an ester of (A) a branched fatty acid obtained from a lanolin fatty acid, and (B) a branched alcohol, preferably 2-octyldodecanol. For example, the component A can be obtained as a nonhydroxy fatty acid from the lanolin fatty acid included in a lanolin, by using a method of converting a hydroxy fatty acid component in the lanolin fatty acid to a boric acid ester, and subjecting the product to a distillation under a reduced pressure to separate the nonhydroxy fatty acid from the hydroxy fatty acid.
