Isopropyl Lanolate ●
TL;DR. This ingredient functions primarily as a rich emollient and skin-conditioning ester. It improves slip, cushion, and adhesion in lip products, creams, ointments, and color cosmetics.
What does Isopropyl Lanolate do in a cosmetic formula?
This ingredient functions primarily as a rich emollient and skin-conditioning ester. It improves slip, cushion, and adhesion in lip products, creams, ointments, and color cosmetics.
Is Isopropyl Lanolate clean?
From a clean-beauty perspective, it is generally acceptable when well purified, but it has friction because it is animal-derived and can be an issue for people with sensitivity to wool-derived residues. It is not a formaldehyde releaser, UV filter, or high-profile restricted-list ingredient.
Is Isopropyl Lanolate sustainable?
This material comes from fatty acids recovered from sheep fleece processing, then esterified with a short-chain alcohol that may be petrochemical or bio-based depending on supplier. It is expected to be more biodegradable than silicone oils, but traceability, animal-welfare standards, and residue controls matter.
Is Isopropyl Lanolate COSMOS-approved?
It may align with COSMOS-natural when sourced from permitted animal-derived fatty acids and made through allowed esterification, but documentation is supplier-specific. Its Green Chemistry profile is mixed, with renewable animal-derived carbon and biodegradable ester chemistry, balanced by chemical modification and variable alcohol sourcing.
How does Isopropyl Lanolate work chemically?
The molecule is a mixture of branched and straight-chain fatty acid esters, which gives it a waxy, substantive feel and strong affinity for skin and pigments. It is typically used at low to moderate levels in anhydrous balms, sticks, and emulsions, and it is more stable to oxidation than highly unsaturated plant oils but can hydrolyze under strongly acidic or alkaline conditions.
