Science

Mechanism of Action

As an ester, Ethyl Undecylenate functions primarily as a skin conditioning agent, providing a smooth, emollient feel that facilitates the elegant spread and absorption of a product's active components. It is recognized for its inherent antifungal capabilities, mirroring its parent compound, undecylenic acid, which acts by disrupting fungal cell membranes, inhibiting morphogenesis, and modulating inflammatory responses. This ingredient also plays a role in enhancing overall formulation stability and extending fragrance longevity.
