3-ISOPENTENYL ISOVALERATE.

Optional CAS 54410-94-5 / PERFUMING

A naturally-occurring ester compound found in essential oils like Artemisia annua and marula fruit, primarily utilized as a fragrance ingredient in skincare formulations. This volatile compound demonstrates high predicted skin permeability (LogKp > -7.0) and may offer minor emollient properties while contributing to botanical extract efficacy through enhanced penetration support.

Summary

perfuming emollient

Science

Mechanism of Action

Functions primarily as a perfuming agent with its volatile, lipophilic structure allowing efficient scent delivery. As an ester compound, it provides subtle emollient benefits to skin barrier function and may facilitate the penetration of other active botanical compounds due to its favorable permeability profile.
