Description

4,4-Dimethyloxazolidine (CAS 51200-87-4) is a cyclic amine biocide and preservative used across industrial and personal care applications. It functions by releasing formaldehyde under aqueous conditions, delivering broad-spectrum antimicrobial activity. This chemical provides effective control against bacteria, fungi, and yeast in various environments. In metalworking and industrial lubricants, it controls microbial contamination in water-miscible cutting fluids and coolants, extending fluid service life.

Personal care formulators incorporate it as a preservative booster in rinse-off and leave-on products. This is particularly common where formaldehyde-donor preservation systems are specified for product stability and safety. In oilfield and water treatment operations, it is used to prevent biofouling and microbiologically influenced corrosion. It is frequently applied in injection water systems and process pipelines to maintain operational integrity.

The compound also functions as a corrosion inhibitor in industrial fluid formulations where microbial-driven degradation accelerates metal attack. This dual-action capability makes it a versatile additive for complex industrial systems. The product is supplied as a liquid, typically as a concentrated aqueous or neat solution. Technical grade is the standard commercial form for industrial applications, while cosmetic-grade material is available for personal care use.

Packaging ranges from drums to IBC totes depending on volume requirements and logistical needs. It is handled according to standard industrial safety protocols to ensure stability and efficacy during storage and transport.
