Abstract
Abstract A method for improving the quality of the fragrance of a perfume or a perfume composition by adding thereto a specific perfume controlling agent which improves emission of a perfume or a perfume composition and its tenacity (fixing effect), and which is an aliphatic dibasic acid diester of the general formula: R.sub.1 OCOR.sub.2 COOR.sub.3 wherein R 1 and R 3 , which may be the same or different, each represents a saturated branched chain alkyl group containing 4 or 5 carbon atoms, and R 2 represents a saturated straight chain alkylene group containing 4 carbon atoms, as an active ingredient.
