Description
Allantoin (CAS 97-59-6) is a naturally derived heterocyclic compound produced synthetically for industrial use, also known under trade names Sebical, Alantan, and Cordianine. It carries no assigned E-code and is classified under HS code 29332100. Its molecular formula is C4H6N4O3.
In personal care formulations, allantoin functions as a skin conditioner and protectant by promoting cell proliferation and accelerating tissue repair, making it a standard active in wound-care creams and post-procedure skincare. In pharmaceutical preparations, it serves as a buffering agent to stabilise pH and contributes mild antimicrobial activity, supporting preservation in topical drug products.
Allantoin is supplied as a white powder meeting Ph.Eur. and USP/NF monograph specifications, with REACH compliance confirmed for EU market supply. Procurement is available in standard laboratory quantities through to bulk industrial packaging. Buyers should request a certificate of analysis confirming purity grade relevant to their intended application.
