guaiacwood extract acetate

Guaiacwood extract acetate is a naturally derived acetate obtained from the Bulnesia sarmientoi tree, commonly known as palo santo or guaiacwood. This compound appears typically as a resinous or viscous material, notable for its woody, vetiver, balsamic, and tea rose odor characteristics. Chemically, it is an acetylated extract that preserves much of the natural aromatic profile of the source material while providing enhanced stability. Synonyms include bulnesia sarmienti extract acetate, acetylated bulnesia sarmientoi extract, and champaca wood acetate. Its sensory notes integrate woody and slightly smoky elements with fruity and vanilla undertones, classifying it as a valuable component in fragrance development. The compound's chemical information is indexed in databases such as PubChem. Guaiacwood extract acetate is typically obtained through solvent extraction and subsequent acetylation of the oleoresins from Bulnesia sarmientoi heartwood, contributing to its use in perfuming applications.

Guaiacwood extract acetate derives from the heartwood of the Bulnesia sarmientoi tree, indigenous to South America. This compound holds significance in fragrance formulations due to its complex aromatic profile, encompassing woody, balsamic, and smoky accords. It is commonly employed to impart notes reminiscent of ambreine, benzoin, and myrrh. Its uses extend to emulating natural materials such as beeswax absolute, cardamom oil, and camphoraceous balsams like copaiba and tolu balsam. Within the flavor industry, it finds specialized uses as a substitute for tropical fruit and balsamic notes, although flavor applications are limited by regulatory recommendations. Guaiacwood extract acetate conforms to fragrance standards including IFRA (Global), which guides usage levels to ensure safety in consumer products. In perfumery, it acts as a versatile ingredient that enhances woody and aromatic complexity while contributing to lasting scent impressions.

Guaiacwood extract acetate exhibits a high logP value of approximately 5.85, indicating pronounced lipophilicity, which influences its solubility in oils and its behavior in fragrance matrices. This compound is generally stable when stored in cool, dry environments, protected from light and heat, with a recommended shelf life of around 24 months or longer under optimal conditions. Its elevated hydrophobicity favors incorporation into oil-based and alcohol-based formulations, where it can provide durable woody and balsamic fragrance facets. The acetate functional group enhances its volatility and modulates its odor profile compared to the parent extract. These physico-chemical properties facilitate its application as a perfuming agent where sustained aroma release and olfactory richness are desired.
