linalyl

Linalyl is a chemical naming term used to denote a substituent derived from linalool. The linalyl group is most commonly encountered in the names of esters and other derivatives formed from linalool, such as linalyl acetate and linalyl propionate. These compounds are part of the broader class of monoterpene derivatives found in many essential oils.

Natural occurrence: Linalool is a major constituent of essential oils from lavender, bergamot, clary sage, and other plants. Through chemical modification, linalool forms linalyl esters that contribute to characteristic floral aromas. Linalyl acetate, in particular, is widely used in the fragrance industry.

Applications: In perfumery and flavoring, linalyl esters provide fresh, floral notes and are often blended with other terpenes. Linalyl acetate is commonly produced industrially by acetylating linalool and is used as a fragrance ingredient and flavor compound.

Safety and regulation: Fragrance ingredients including linalyl acetate and linalool can cause skin sensitization in some individuals; these substances are subject to allergen labeling requirements in various regions. Proper handling and storage can minimize oxidation and odor changes.
