What it is
Menthanediol is a diol within the menthane terpene family, structurally related to menthol. In cosmetics it is valued for the cooling, fresh sensory effect it lends to formulas without the sharp odor of menthol itself. It is commonly found in cooling sunscreen sprays, sticks, and gels designed to feel refreshing on application.
Safety & warnings
At cosmetic use levels menthanediol is generally well tolerated, though its cooling action may feel intense on very sensitive or compromised skin, and tingling can occur. Individuals who react to mint- or menthol-type cooling agents should approach cooling formulas with caution.
