Lanolin ●
TL;DR. This ingredient is an occlusive emollient and water-binding conditioning agent. It softens skin and lips, reduces transepidermal water loss, and adds cushion to balms, ointments, creams, and hair products.
What does Lanolin do in a cosmetic formula?
This ingredient is an occlusive emollient and water-binding conditioning agent. It softens skin and lips, reduces transepidermal water loss, and adds cushion to balms, ointments, creams, and hair products.
Is Lanolin clean?
From a clean-beauty perspective, it is effective but more nuanced than many plant oils because oxidized fractions and residual pesticides can be sensitization concerns for some users. Highly refined, low-residue grades are generally better tolerated and are the versions most consistent with stricter standards.
Is Lanolin sustainable?
It is a renewable byproduct of sheep-fleece processing, so its footprint is tied to wool supply chains, land use, animal welfare, and scouring effluent management. It is inherently biodegradable, but its waxy structure can break down more slowly than simple small-molecule humectants.
Is Lanolin COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic when sourced from living animals and processed with allowed methods, with attention to residue limits. Its Green Chemistry profile is mixed: renewable and biodegradable, but purification can be energy- and water-intensive and depends on responsible agricultural supply chains.
How does Lanolin work chemically?
This material is a complex semi-solid mixture rich in long-chain wax esters, sterol esters, free sterols, fatty alcohols, and fatty acids, giving it high water-absorption capacity rather than simple oil behavior. It is commonly used around 1 to 20% in balms, creams, and lip products, is stable across typical skin-care pH ranges, and benefits from antioxidant support because unsaturated fractions can oxidize over time.
