Iso Longifolene Ketone, also known as Ketone 101 or Woodysol, is a synthetic aroma chemical belonging to the ketone family. It is valued in perfumery for its unique woody, amber, dry, and cedary odor profile, often described as having balsamic, slightly musky, and powdery facets. It typically appears as a clear to pale yellow liquid. This compound is derived from longifolene, a naturally occurring sesquiterpene, and is a key ingredient for imparting rich, long-lasting woody notes to various fragrance compositions.
It is primarily used as a fragrance ingredient in a wide array of consumer products. Its excellent tenacity and versatility make it suitable for both fine fragrances and functional perfumery applications.
Applications include fine perfumes, colognes, soaps, detergents, shampoos, conditioners, air fresheners, fabric softeners, candles, and other personal care products. It is particularly effective in creating or enhancing woody, amber, chypre, and oriental accords.
As a fragrance ingredient, Iso Longifolene Ketone is subject to industry standards and regulations, such as those set by the International Fragrance Association (IFRA). While generally considered safe for use in fragrances at recommended levels, like many aroma chemicals, it has the potential to cause skin sensitization or irritation in susceptible individuals. Users should always consult the Safety Data Sheet (SDS) for detailed information on safe handling, storage, and disposal, including hazard statements (e.g., H317: May cause an allergic skin reaction) and precautionary measures.
