Ilomastat ●
TL;DR. This ingredient is a synthetic skin-conditioning active used for anti-aging claims tied to matrix metalloproteinase inhibition. In formulas, it is positioned to help target pathways associated with collagen and elastin breakdown rather than to provide basic moisturization or preservation.
What does Ilomastat do in a cosmetic formula?
This ingredient is a synthetic skin-conditioning active used for anti-aging claims tied to matrix metalloproteinase inhibition. In formulas, it is positioned to help target pathways associated with collagen and elastin breakdown rather than to provide basic moisturization or preservation.
Is Ilomastat clean?
From a clean beauty perspective, this ingredient sits outside the usual low-friction palette because it is a bioactive, drug-like synthetic enzyme inhibitor with limited public cosmetic-use data. The concern is less about classic allergens and more about conservative standards, evidence depth, and mechanism-driven scrutiny.
Is Ilomastat sustainable?
This material is synthetic and typically associated with multi-step organic chemistry rather than renewable feedstocks. Public data on biodegradability and aquatic fate are limited, so its environmental profile is not especially strong.
Is Ilomastat COSMOS-approved?
It is not permitted under COSMOS organic or natural standards because it does not fit the standard’s allowed natural, naturally derived, or specifically approved synthetic categories. Its likely petrochemical feedstocks, multi-step synthesis, and limited biodegradability data give it weak Green Chemistry alignment.
How does Ilomastat work chemically?
The molecule is a peptidomimetic hydroxamate, with a zinc-binding hydroxamic acid group that can interact with the catalytic metal center of matrix metalloproteinase enzymes. Hydroxamate chemistry can be sensitive to hydrolysis and metal interactions, so compatibility with extreme pH, strong chelators, and metal-containing systems needs formulation review.
