Natural fragrance companies are often interested in the olfactory impact that plant extracts can have on the design of new facets of fragrances. The hydrodistillation of plants yields essential oils characterized by molecules with relatively high volatility that often are used for the top and middle notes—the two most volatile fractions—of a fragrance. Traditional aromatherapy has claimed that essential oils have activity on the skin but only recently has research substantiated that essential oils can act as actives in cosmetic products. For example, the most recognized use of essential oils has been for antimicrobial activity against P. acnes or M. furfur for acne and antidandruff applications. Moreover, studies have highlighted the use of essential oils as potential antiinflammatory and antioxidant agents.
