Dimethylolurea

Dimethylolurea (CAS 140-95-4) is a urea-formaldehyde condensate also known by trade names Caurite, Carbamol, Methural, and Oxymethurea. It carries no assigned E-code and is classified under HS code 29241990. It belongs to the polymers and resins category and is handled as a white crystalline powder.

In textile and leather finishing, dimethylolurea functions as a cross-linking agent, forming covalent bonds with cellulose hydroxyl groups to impart crease resistance and dimensional stability to fabrics. In pulp and paper manufacturing, it acts as a wet-strength resin precursor, and in adhesive and coating formulations it contributes to rheology modification by influencing polymer network density during cure.

Dimethylolurea is supplied in powder and crystalline grades and is subject to REACH registration requirements for EU procurement. Buyers should confirm supplier documentation including SDS, certificate of analysis, and REACH compliance status. Standard packaging formats vary by supplier; bulk and intermediate bag options are typically available.
