TL;DR. This ingredient is a skin-conditioning emollient and occlusive agent that adds slip, gloss, and water resistance to balms, lip products, creams, and color cosmetics.
What does Acetylated Lanolin do in a cosmetic formula?
This ingredient is a skin-conditioning emollient and occlusive agent that adds slip, gloss, and water resistance to balms, lip products, creams, and color cosmetics.
Is Acetylated Lanolin clean?
From a clean-beauty perspective, it has some friction because it is animal-derived and may not suit people with wool-wax sensitivity. It is not a major restricted-list ingredient, but vegan standards and allergy-focused standards may flag it.
Is Acetylated Lanolin sustainable?
This material is sourced from sheep fleece as a byproduct of wool production, so its footprint depends on animal-welfare practices, land use, and cleaning processes. It is expected to be biodegradable, but it is not plant-based and its supply chain is less simple than common vegetable oils.
Is Acetylated Lanolin COSMOS-approved?
It can fit COSMOS-natural when the animal source and processing meet the standard, but it is not compatible with vegan claims and would not be counted as a plant-derived organic input. Its Green Chemistry profile is mixed, with a renewable animal feedstock and good degradability balanced by chemical modification and sourcing caveats.
How does Acetylated Lanolin work chemically?
The molecule is a chemically modified mixture of long-chain sterol esters, fatty alcohol esters, and related wax esters with acetyl groups that make the material less tacky and more oil-soluble. It is typically used at low to moderate levels in anhydrous and emulsion systems, is stable across normal cosmetic pH ranges, and is best handled with heat because of its waxy, hydrophobic character.
