TL;DR. This ingredient is primarily an occlusive emollient and skin-conditioning agent. It helps reduce water loss, adds cushion, and improves the feel of balms, creams, ointments, and lip products.
What does Lanolin Usp do in a cosmetic formula?
This ingredient is primarily an occlusive emollient and skin-conditioning agent. It helps reduce water loss, adds cushion, and improves the feel of balms, creams, ointments, and lip products.
Is Lanolin Usp clean?
From a clean-beauty perspective, it has some friction because it is animal-derived and can be associated with sensitivity in a small subset of users. Purified grades are valued for lower residue and odor profiles, but allergen screening and sourcing standards matter.
Is Lanolin Usp sustainable?
This material is recovered as a byproduct of sheep fleece processing, so it uses an existing agricultural stream rather than a dedicated crop or petrochemical feedstock. It is biodegradable, but its sustainability profile depends on animal-welfare practices, land use, and residue controls in the supply chain.
Is Lanolin Usp COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic frameworks when it meets rules for non-plant animal-derived materials and processing quality. Its Green Chemistry fit is moderate to good because it is renewable and biodegradable, although sourcing transparency is central to the assessment.
How does Lanolin Usp work chemically?
Chemically, it is a complex mixture of long-chain wax esters, sterol esters, fatty alcohols, fatty acids, and related lipids, which explains its strong water-binding and occlusive feel. Typical use ranges from about 0.5% to 5% in creams and lotions, with higher levels in balms and ointments, and it is oil-phase compatible, broadly pH-stable, and best protected from heat-driven oxidation and odor development.
