Dimethylol glycol

Dimethylol glycol (CAS 3586-55-8) is a diol compound based on an ethylene glycol backbone, commercially available under trade names including Dascocide 9 and Nipacide FC. It carries no assigned E-code and is sometimes referenced in analytical contexts as Glycerol Impurity 5.

In textile and leather processing, dimethylol glycol functions as a cross-linking agent, forming covalent bonds with hydroxyl groups in cellulose or collagen to improve dimensional stability and wet strength. In coatings and adhesive formulations, it acts as a reactive plasticizer, incorporating into the polymer network to reduce brittleness without compromising film integrity.

Dimethylol glycol is supplied for industrial applications and falls under REACH registration requirements for EU procurement. Buyers should confirm grade specification and purity documentation directly with the supplier, as available forms and packaging formats vary by production source.
