Methylenebis(5-methyloxazolidine)

Methylenebis(5-methyloxazolidine) (CAS 66204-44-2), commercially known as Grotan OX, is a formaldehyde-releasing biocide used to control microbial growth in industrial and personal care formulations.

Where is Methylenebis(5-methyloxazolidine) used?

• Metalworking and industrial lubricants: protects cutting fluids and coolants from bacterial spoilage that degrades performance and shortens fluid service life
• Coatings, adhesives and sealants: in-can preservative against microbial contamination during storage and application
• Personal care: preservative booster in rinse-off and leave-on products
• Water treatment: controls biofilm formation in recirculating systems and process water
• It acts by slowly releasing formaldehyde under aqueous conditions, providing sustained antimicrobial protection against bacteria and fungi.

Good to know: Technical grade is the standard form for industrial applications including metalworking fluids and coatings; cosmetic-grade material meeting relevant regulatory specifications is available for personal care end uses.
