Ethyl Macadamiate

INCI: Ethyl Macadamiate

Ethyl Macadamiate is the ethyl ester of the fatty acids derived from macadamia nut oil. It functions as a lightweight, fast-absorbing emollient that conditions and softens the skin without a heavy or greasy feel. Its fatty acid profile is similar to human sebum, which contributes to excellent skin compatibility and a natural, non-occlusive finish.
