HEPTANAL.

Questionable CAS 111-71-7 / PERFUMING

Heptanal is an n-alkanal, a type of aldehyde, that occurs naturally in various essential oils. While it is an endogenous aldehyde in biological systems, its primary application in cosmetic formulations is as a perfuming agent, not for specific skin benefits.

Science

Mechanism of Action

Heptanal functions primarily as a perfuming agent in cosmetic applications, contributing to the fragrance profile of products. Its specific mechanism of action on the skin for therapeutic or beneficial cosmetic effects is not detailed in current research data, differentiating it from its biological role as an endogenous aldehyde from lipid oxidation.
