Description
N-(2-Hydroxyethyl)ethyleneurea (CAS 3699-54-5) is a cyclic urea derivative also known under trade designations including SR 511, SR 511A, Ucar RD 65-2, and Sartomer SR 511. It carries no assigned E-code. The compound belongs to the heterocyclic chemical category and is registered under EC number 223-032-9.
In textile finishing, it functions as a durable press agent by forming covalent crosslinks with cellulose fibers, reducing fabric shrinkage and creasing. In personal care formulations, it acts as a humectant by attracting and retaining moisture within the skin matrix. Leather and paper processing applications exploit the same hygroscopic mechanism to maintain substrate flexibility and dimensional stability.
This material is supplied as a solid and is subject to REACH registration requirements for European market access. Procurement teams should confirm available pack sizes and purity grades directly with the supplier, as specifications may vary by production batch and intended application sector.
