Ethyl Macadamiate

Ethyl macadamiate is the ester of ethyl alcohol mixed with fatty acids from macadamia nut oil to create an emollient. On skin, ethyl macadamiate softens and conditions plus helps prevent moisture loss. This plant-derived or synthetically made ingredient is sometimes used as a substitute for silicones because it imparts emollient, skin-softening properties without the greasy feel higher amounts of some silicones can have. Ethyl macadamiate also adds a pleasant slip to creams and lotions, making them easier to spread, not to mention macadamia nut oil is a rich source of essential fatty acids for skin. You can find ethyl macadamiate in all kinds of cosmetic formulations including cleansing oils, moisturisers, sunscreens, and hair care products. Amounts used in cosmetics may be as low as 0.1% in a cleanser to upwards of 30% in a non-aqueous serum or moisturiser. The Cosmetic Ingredient Review Expert Panel has deemed macadamia nut oil safe as used in cosmetics; the ethyl alcohol portion isn’t considered a risk since it does not retain its original properties when esterified with oil to form ethyl macadamiate.
