Science
Mechanism of Action
This ingredient operates through a dual mechanism: its glycerin component attracts and binds water, enhancing skin hydration. Concurrently, the undecylenic acid moiety provides broad-spectrum antimicrobial activity, effectively inhibiting the reproduction and growth of bacteria, yeast, and fungi, thus acting as a preservative and supporting skin health. It also softens the skin's surface and improves emulsion texture.

Safety
Safety Profile
The CIR Expert Panel affirmed Glyceryl Undecylenate as safe for cosmetic use under current practices and concentrations. While undiluted forms may cause minor, temporary irritation on abraded skin, it is generally non-irritating and not considered a sensitizer at concentrations typically used in cosmetics. Global regulatory bodies, including those in Europe, the United States (FDA GRAS list for some food applications), and Japan, recognize its safety for both rinse-off and leave-on products within recommended limits.
