Resin Acid in Tree Moss Extract

Lichens are symbiotic organisms of fungi and algae. The biological significance of lichens and their metabolites has been reviewed by Huneck, who even stated that “good perfumes require lichen extracts.”

Aleuritic Acid in Perfumery and Pheromones

The brief account given above indicates the vast potential which aleuritic acid holds in the synthesis of numerous useful organic compounds possessing olfactory properties. With a steady and substantial availability of threo aleuritic acid, its utility is expected to increase enormously.

Fragrant Esters of 3-Cyclohexylbutanoic Acid

Thus, the acid is not too easily available, but remarkable fragrant properties of its esters raise the interest in its production. The first four stages of its synthesis have been described previously. Prin’s reaction of α-methylstyrene with formaldehyde yields 4-methyl-4-phenyl-1,3-dioxane.

iso-Valeric acid makes a subtle, but very useful, contribution to hazelnut flavors at 100 ppm.

iso-Valeric Acid in Dairy, Brown, Nut, Savory, Alcoholic Drink & Fruit Flavors

The profile of iso-valeric is very much stereotypical of the primary cheese odor, without any hint of the faint goaty character that starts to creep into the series of aliphatic acids from six carbon atoms upwards.

HESP—A New Essential Oil From the Acid Hydrolysate of Spent Sandal Heartwood

In the present study, the utilization of the spent (exhausted) sandalwood powder from steam distillation as a source of an acid hydrolysate oil is examined. It has been found that hydrolysis of the non-volatile portion of an acetone extract of the spent sandalwood powder with methanolic hydrochloric acid followed by steam distillation gave rise to a new essential oil (1.2% yield) which we have called HESP, the acronym for hydrolyzed exhausted sandalwood powder.

5 Trends Shaping the Bath & Body Care Industry

Scent experiences, line extensions, collaborations, body sprays, and hand care are leading the way in bath and body care innovation.

Vanilla flavor is dominated by phenols and their transformation products mostly derived from enzymatic hydrolysis of the phenyl-β-D-glucosides. Cocoa bean flavor is dominated by Strecker aldehydes and pyrazines and other products generated during the roasting process of the beans.

Extracting the Essence: Comparing Vanilla and Cocoa Processes

Understanding the similarities and differences in biochemistry, chemistry and curing processes of vanilla and cocoa may offer insight into producing high-quality materials.
