INCI: ALPHA-PINANOL
Alpha-Pinanol is a natural fragrance ingredient with mild antimicrobial properties, but it may cause irritation in sensitive skin at higher concentrations.
In plain English
Alpha-Pinanol is a natural alcohol found in pine and other essential oils. In skincare, it's mainly used to add a fresh, pine-like scent to products.

What it is
Alpha-Pinanol is a terpene alcohol derived from pine trees and other plants. It is a colorless liquid with a characteristic pine aroma and is commonly used as a fragrance ingredient in cosmetics and personal care products.
How it works
In a cosmetic product, Alpha-Pinanol primarily functions as a fragrance agent, providing a fresh, woody scent. It also exhibits mild antimicrobial activity, which can help reduce the growth of certain bacteria and fungi on the skin or in the product itself. Its small molecular size allows it to evaporate quickly, contributing to a light sensory feel.
