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.

It acts by slowly releasing formaldehyde under aqueous conditions, providing sustained antimicrobial protection across a broad spectrum of bacteria and fungi. This mechanism ensures long-term stability in various environments.

In metalworking and industrial lubricants, it protects cutting fluids and coolants from bacterial spoilage that would otherwise degrade performance and shorten fluid service life. This is critical for maintaining operational efficiency.

Coatings, adhesives, and sealant manufacturers incorporate it as an in-can preservative to prevent microbial contamination during storage and application. This prevents product spoilage and maintains the integrity of the chemical bond.

Personal care formulators use it as a preservative booster in rinse-off and leave-on products where broad-spectrum efficacy is required. It helps ensure that consumer products remain safe throughout their entire shelf life.

Water treatment applications rely on it to control biofilm formation in recirculating systems and process water. This prevents clogging and corrosion in industrial cooling towers and large scale manufacturing piping systems.

Methylenebis(5-methyloxazolidine) is supplied as a clear to slightly yellow liquid. It is available in technical grade, 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. Our material is manufactured to meet rigorous quality standards to ensure consistent performance in every batch.
