(+)-Usniacin Chemical Properties,Uses,Production
Uses
Usnic acid is used as fragrance; preservative in deodorants; in anti ac ne formulations; antibiotic for topical application.
Contact allergens
Usnic acid is a component of lichens, also used as a topical antibiotic. Allergic contact dermatitis from lichens occurs mainly occupationally in forestry and horticultural workers, and in lichen pickers.
Purification Methods
This very weak acid is the natural form which is recrystallised from Me2CO, MeOH or *C6H6. At 25o it is soluble in H2O (<0.01%), Me2CO (0.77%), EtOAc (0.88%), MeOCH2CH2OH (0.22%) and furfural (7.32%).
