Isopulegol

What is Isopulegol?

Isopulegol is a chiral monoterpenoid alcohol, chemically derived from the reduction of pulegone, a ketone found in pennyroyal oil and other mint-related essential oils. Synthetically produced for purity and consistency, it exists as a clear, colorless to slightly yellow liquid with a characteristic fresh, herbaceous, peppermint-like aroma and subtle cooling sensation. In cosmetic formulations, it belongs to the category of volatile aroma compounds primarily incorporated into rinse-off and leave-on products such as toothpastes, mouthwashes, perfumes, lotions, and shampoos. It functions by dissolving into the oil or water phases, releasing its scent molecules gradually to define the product's olfactory profile, reinforce flavor notes in oral products, and neutralize base material odors through competitive sensory binding, thereby elevating the overall user experience without impacting texture or efficacy.
