Chloroallyl methenamine chloride

Chloroallyl methenamine chloride (CAS 51229-78-8), the cis-form of Quaternium-15, is a formaldehyde-releasing biocide that controls microbial growth in water-based industrial and personal care formulations.

Where is Chloroallyl methenamine chloride used?

• Coatings and adhesives: protects water-based systems such as latex paints and construction adhesives from spoilage during storage and in-can use
• Personal care: preservative in rinse-off and leave-on products such as shampoos, conditioners and lotions
• Sealants and elastomers: extends shelf life of aqueous dispersions prone to bacterial contamination
• In metalworking fluids and industrial water treatment it controls microbes that affect process integrity.

Good to know: It works by generating controlled formaldehyde in situ, giving broad-spectrum preservation against bacteria, yeasts and molds. Broad pH-range antimicrobial efficacy is a key selection criterion.

Commercial specifications

• Aqueous solution with active concentrations typically 96–98%
