The present invention provides oils for cosmetics comprising a dibasic acid diester represented by general formula (I) (wherein R, R, Rand R, which are the same or different, each represent lower alkyl)and excellent in solubility of a long-wave ultraviolet light absorber or the like, and so forth.

Oily ingredient for cosmetic preparation and cosmetic preparation

The present invention provides the following process for production of an ether compound, which is useful for chemical amplification type resist compositions, synthetic intermediates of pharmaceuticals, paints, or the like, with less side reaction and in high yield. A process for producing an ether compound having a group represented by the general formula (II) wherein R, Rand Rmay be the same or different, and represent substituted or unsubstituted alkyl, substituted or unsubstituted aryl or substituted or unsubstituted aralkyl, or Rand Rform cycloalkyl together with an adjacent carbon atom, which comprises allowing a compound having a hydroxyl group (including a carboxyl group) to react with an alkenyl ether represented by the general formula (I) wherein R, Rand Rhave the same significances as defined above, respectively.
