Ethyl Undecylenate
Ethyl undecylenate is the ethyl ester of undecylenic acid used in formulations as a lightweight, dry-touch emollient. It's selected for a soft-matte, less-greasy finish that improves spreadability in primers, sunscreens, and oil-control care.

Our take
Is Ethyl Undecylenate a Good Ingredient?
Rated Fair: offers a dry-touch, soft‑matte finish and improves spreadability, but strong evidence for sustained oil control is limited. May feel drying and could trigger mild irritation on sensitive or barrier‑impaired skin.
What it does
Skin Benefits
Helps reduce the look of surface shine for a soft‑matte finish while keeping skin comfortable. Effects are mainly aesthetic; sustained oil-control benefits beyond feel are not well substantiated.
Where you'll find it
Uses in Skincare & Cosmetics
Used in mattifying moisturizers, oil-control serums, and setting gels to deliver a dry-touch finish. Also incorporated into lightweight body lotions for quick absorption.
Before you use it
Safety
Usually low in irritation, but its matte, fast‑evaporating feel can accentuate dryness or sensitivity; patch test if reactive. No widely established regulatory constraints for cosmetic leave‑on products.
