Allantoin[1][3][7] ●
TL;DR. This ingredient is a skin-conditioning and protectant active used to support comfort, smoothness, and a less rough feel in creams, serums, cleansers, and after-shave products.
What does Allantoin[1][3][7] do in a cosmetic formula?
This ingredient is a skin-conditioning and protectant active used to support comfort, smoothness, and a less rough feel in creams, serums, cleansers, and after-shave products.
Is Allantoin[1][3][7] clean?
This ingredient is well accepted in clean-beauty frameworks because it has a low sensitization profile and no major restricted-list friction at typical cosmetic levels. It is often used in products positioned for sensitive or compromised-feeling skin.
Is Allantoin[1][3][7] sustainable?
This material is usually made synthetically, though it is nature-identical to a compound found in plants and animals. It is used at low levels, is not known for environmental persistence, and has a relatively simple supply-chain profile compared with botanicals or mined materials.
Is Allantoin[1][3][7] COSMOS-approved?
It is compatible with COSMOS natural and organic formulations when supplied in an approved grade that meets purity and processing requirements. From a Green Chemistry view, its strengths are low use level, good tolerance, and limited persistence, while its weaker point is that many commercial grades rely on synthetic feedstocks.
How does Allantoin[1][3][7] work chemically?
The molecule is a small, water-soluble heterocyclic ureide with multiple hydrogen-bonding sites, which helps explain its humectant-adjacent and skin-comfort role. Typical use is about 0.1% to 0.5% in cosmetics, with higher skin-protectant levels in some regulated products, and formulators usually dissolve it with heat because room-temperature water solubility is limited.
