Allantoin is a heterocyclic compound used as a skin-conditioning active in soothing and after-sun leave-on care. It is not a fragrance. The material is a white crystalline powder that is sparingly soluble in water and more readily dispersed in warm water or glycols.

Creams, gels, and after-sun lotions continue to specify this INCI because the assay and the low use level are easy to control. Cosmetic-grade Allantoin remains a high-volume bulk active for comfort formulas.
