⚗️Uses — Its field of application reaches from the finest luxury perfumes to inexpensive masking odors, from Gardenia flower bases to Coconut candy flavors, etc. Its intense sweetness and tenacity are often utilized alongside Undecanolide (so-called Aldehyde C-14) in Gardenia, Tuberose, Honeysuckle, Stephanotis, Plumeria, Jasmin, and many other heavy floral types. Modern fantasy perfumes with emphasis on musk and lactones may include the title material and produce an unusual fixative effect of overwhelming sweetness, and novel versions of Oriental fragrance types can be made with Sandalwood, Styrax, and the tide lactone as part of the base. The perfumer often underestimates its power (if he has no experience as a flavorist) and the lactone will “grow” out of the perfume and unpleasantly dominate the fragrance. (S. Arctander)
