ETHYL LINOLEATE

Ethyl Linoleate is the ethyl ester of linoleic acid, an omega‑6 polyunsaturated fatty acid with two cis double bonds.
Ethyl Linoleate is widely used in cosmetics and personal care products for its emollient properties, skin conditioning performance, and potential anti-inflammatory and anti‑acne effects.
Ethyl Linoleate appears as a clear to pale yellow liquid with a mild, floral-like odor.

DESCRIPTION

Ethyl Linoleate is the ethyl ester of linoleic acid, a polyunsaturated omega-6 fatty acid.
Ethyl Linoleate is a clear to light yellow liquid with excellent skin-penetrating ability.
Ethyl Linoleate is valued in cosmetic applications for its high content of essential fatty acids.

Ethyl Linoleate plays a crucial role in restoring and maintaining the skin's lipid barrier.
Ethyl Linoleate is used in dermatology for its anti-inflammatory and skin-repairing benefits.

Ethyl Linoleate is quickly absorbed into the skin, leaving a soft and hydrated feel.
Ethyl Linoleate is naturally derived from sources such as sunflower or safflower oil.

Ethyl Linoleate is compatible with a wide range of cosmetic emollients and active ingredients.
Ethyl Linoleate improves the delivery of active ingredients by enhancing skin permeability.

Ethyl Linoleate is considered non-comedogenic and suitable for sensitive and oily skin types.
Ethyl Linoleate is synthesized by esterification of linoleic acid—commonly sourced from safflower, sunflower, or corn oils—with ethanol.

The compound forms a non-greasy, lightweight liquid that penetrates quickly and leaves a silky skin feel.
Ethyl Linoleate is non-reactive under normal conditions but can oxidize upon exposure to heat, light, or air.
Ethyl Linoleate exhibits skin-conditioning properties and may help moderately reduce melanogenesis by inhibiting α‑MSH–induced pigmentation in vitro.
It blends well with oils, esters, and many silicones or lipid bases in cosmetic formulations.
Ethyl Linoleate is biodegradable and generally well tolerated by most skin types, including oily or acne-prone skin .
