About Beta Damascone

Beta Damascone is a naturally inspired rose ketone derivative that contributes a deep, floral-woody character to fine perfumery. Slightly less fruity than alpha damascone, it imparts depth, warmth, and complexity in rose, tobacco, woody, and oriental compositions. Highly diffusive and powerful even at low concentration...
