Ethyl Macadamiate ●
TL;DR. This ingredient functions as a lightweight emollient and skin-conditioning agent, adding slip, softness, and a dry, silky finish to creams, lotions, oils, and color cosmetics.
What does Ethyl Macadamiate do in a cosmetic formula?
This ingredient functions as a lightweight emollient and skin-conditioning agent, adding slip, softness, and a dry, silky finish to creams, lotions, oils, and color cosmetics.
Is Ethyl Macadamiate clean?
From a clean-beauty perspective, it is generally well tolerated and not a common restricted-list concern. Because the feedstock is nut-derived, brands may document allergen controls, although refined ester ingredients typically contain little to no residual protein.
Is Ethyl Macadamiate sustainable?
This material is typically made from renewable plant fatty acids and alcohol rather than fully petroleum-based inputs. It is expected to be readily biodegradable, with the main sustainability questions tied to agricultural sourcing, traceability, and land and water use for the crop.
Is Ethyl Macadamiate COSMOS-approved?
It is generally compatible with COSMOS Natural, and it may fit COSMOS Organic formulas when the agricultural inputs and processing route meet certification rules. Its Green Chemistry profile is favorable because it uses renewable feedstocks, an allowed esterification pathway, and biodegradable fatty-chain chemistry.
How does Ethyl Macadamiate work chemically?
The molecule is a fatty-acid ester mixture rich in long-chain monounsaturated components, which gives low-grease emollience and good spread without silicone chemistry. It is commonly used around 1 to 20% in the oil phase, is most stable in anhydrous or near-neutral systems, and benefits from antioxidant support because unsaturated chains can oxidize over time.
