Allantoin ●
TL;DR. This ingredient is primarily used as a soothing skin-conditioning agent and mild keratolytic. It helps support a smoother feel in formulas for irritated, dry, or rough-looking skin.
What does Allantoin do in a cosmetic formula?
This ingredient is primarily used as a soothing skin-conditioning agent and mild keratolytic. It helps support a smoother feel in formulas for irritated, dry, or rough-looking skin.
Is Allantoin clean?
This ingredient is generally well tolerated and has a low irritation profile at typical cosmetic levels. It does not carry major clean-standard restricted-list friction when made to cosmetic purity specifications.
Is Allantoin sustainable?
This material is usually produced by controlled chemical synthesis rather than plant extraction, so its footprint depends on the feedstocks and manufacturing controls used. It is water-soluble and generally has a favorable biodegradability profile, with low concern for environmental persistence.
Is Allantoin COSMOS-approved?
This ingredient is permitted under COSMOS standards when it meets the required origin, processing, and purity criteria. From a Green Chemistry view, it scores well on low use levels and biodegradability, though many commercial grades are not strongly renewable-feedstock driven.
How does Allantoin work chemically?
The molecule is a small heterocyclic diureide with multiple hydrogen-bonding sites, which supports its water interaction and skin-conditioning behavior. Typical cosmetic use is about 0.1% to 0.5%, with limited water solubility, so it is commonly dissolved in the heated water phase and can recrystallize if pushed above its solubility limit.
