Description
3,3'-Methylenebis[5-methyloxazolidine] is a formaldehyde-releasing oxazolidine biocide registered under CAS 66204-44-2 and EC 266-235-8. It is commercially available under trade names including MAR 71, Grotan OX, and Acticide OX. No E-code designation applies to this substance.
In metalworking fluids, it controls bacterial and fungal growth by releasing formaldehyde slowly under aqueous conditions, extending fluid service life and reducing disposal frequency. In water treatment and coatings, it functions as an in-can preservative, inhibiting microbial proliferation that would otherwise cause product degradation and corrosion of metal substrates.
This compound is supplied as a liquid concentrate and is subject to REACH registration requirements within the European Union. As a biocidal active substance, its use in certain product types is governed by the EU Biocidal Products Regulation (BPR 528/2012). Buyers should confirm current authorisation status for their intended application and market.
