Optically active muscone composition and fragrances or cosmetics containing the same

Abstract

(Problem) The object of the invention relates to a development of a new musk-feeling fragrance material which is a highly scenting musk-feeling fragrance, and is to provide a fragrance composition which, when added to fragrances or cosmetics, can improve the fixative property and express a high performance and excellent musky aromatic quality. (Means for resolution) A fragrance composition is prepared using, as the active ingredient, a mixture of (R)-form of optically active muscone with (S)-form of optically active muscone with the mixing ratio thereof within the range of from 90:10 to 95:5 (weight ratio) in terms of weight ratio, or a mixture of (R)-form of optically active muscone with (S)-form of optically active muscone with the mixing ratio thereof within the range of from 75:25 to 80:20 (weight ratio) in terms of weight ratio.
