The anti-aging cosmetic composition according to claim 1, wherein the cosmetic composition is one or more selected from myristyl, capryryl eicosenoate, hexyl laurate, lanolin, petrolatum, liquid paraffin, beeswax and squalane.

Column adsorption purification is a column chromatographic method devised by Croda Japan Co., Ltd. (Japanese Patent Laid-Open No. Sho 62-205005). According to this method, polar impurities in the oil can be removed, and are colorless, odorless, and skin irritant. Therefore, it is possible to obtain an oil agent having a small amount of oxidation stability over time. The column chromatographic method is a purification method in which crude oil is dissolved in a nonpolar solvent, passed through an adsorption tower packed with an adsorbent, polar impurities are adsorbed and removed, and then the nonpolar solvent is distilled off. is there. Examples of the nonpolar solvent include aliphatic hydrocarbons such as n-hexane, n-heptane, and petroleum ether, and examples of the adsorbent include silica gel, magnesium silicate, activated clay, zeolite, and the like, and mixtures thereof.
