C10-30 Cholesterol/Lanosterol Esters ●
TL;DR. This ingredient is a rich emollient and skin-conditioning lipid used to soften, reduce water loss, and improve the cushion of balms, creams, lip treatments, and anhydrous products.
What does C10-30 Cholesterol/Lanosterol Esters do in a cosmetic formula?
This ingredient is a rich emollient and skin-conditioning lipid used to soften, reduce water loss, and improve the cushion of balms, creams, lip treatments, and anhydrous products.
Is C10-30 Cholesterol/Lanosterol Esters clean?
From a clean-beauty perspective, it is generally well tolerated and not a common restricted-list issue. The main caveat is sourcing and purification, since residual wool-wax impurities can matter for very reactive skin.
Is C10-30 Cholesterol/Lanosterol Esters sustainable?
This material is commonly sourced from wool-wax-derived sterols and long-chain fatty acids, so it can use an animal byproduct rather than a dedicated crop. It is expected to be biodegradable as a lipid ester, with sustainability depending on wool supply-chain practices and processing controls.
Is C10-30 Cholesterol/Lanosterol Esters COSMOS-approved?
It can align with COSMOS-natural when the feedstocks are natural-origin and the esterification route follows allowed processing rules, but it is not automatically COSMOS-organic. From a Green Chemistry lens, it has a reasonable profile when derived from renewable byproduct streams and made with controlled, low-residue chemistry.
How does C10-30 Cholesterol/Lanosterol Esters work chemically?
The molecule is best understood as a mixture of long-chain fatty acid it attached to rigid sterol alcohol backbones, giving it a waxy, lipophilic character and strong affinity for skin barrier lipids. It is typically used in low-to-moderate percentages in emulsions, balms, sticks, and ointments, and it is stable across normal cosmetic pH ranges because it sits in the oil phase rather than the water phase.
