Common Name(s): Ethyl linolenate,ethyl linolenate,ethyl ester,simple ethanol ester emollient
CAS Number: N/a
DESCRIPTION
What It Does: Provides alpha-linolenic c18:3 fatty acid emolliency in the lightest possible ester format — ethyl esters have the lowest molecular weight of any ester class, providing maximum sc penetration with minimal occlusive film.
Why It's Used: Ethyl linolenate is selected for the ethyl ester format — ethanol's c2 chain provides the lightest, most rapid-penetrating ester matrix for alpha-linolenic c18:3 fatty acid delivery, penetrating the sc faster than any other ester of the same acid.
How It Works: Ethyl ester: minimal steric bulk → maximum sc penetration rate; short ethyl chain → near-zero occlusion film; acid chain (alpha-linolenic c18:3) → specific emollient and barrier repair properties.
Typically Found In: Light emollient formulas,serums

SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 1/5 – low; formulation-dependent
Sensitivity Concerns: Non-irritating.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Humectants,ceramides,actives as carrier
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Ethyl esters penetrate sc faster than isopropyl or ethylhexyl esters of the same fatty acid — the minimal ethyl group provides the optimal sc diffusion rate for rapid-absorbing formulas.
