Hydantoin

Hydantoin (CAS 461-72-3, EC 207-313-3) is a heterocyclic organic compound also known as Glycolylurea or NSC 9226. It carries no assigned E-code and is classified under HS code 29332100. The compound serves as a key building block and functional ingredient across personal care and pharmaceutical manufacturing.

In cosmetic formulations, hydantoin acts as a skin conditioner and buffer by stabilising pH and supporting the integrity of the stratum corneum. It also functions as a preservative precursor, where derivatives release controlled levels of formaldehyde to deliver antimicrobial activity against bacteria and fungi. In pharmaceutical synthesis, it serves as a structural scaffold for producing amino acid analogues and anticonvulsant compounds.

Hydantoin is supplied as a fine white powder in pharmaceutical and technical grades, compliant with REACH registration requirements. Buyers should confirm suitability against Ph.Eur. or in-house specifications depending on end application. Standard packaging includes 25 kg fibre drums, with bulk quantities available on request.
