Sodium hydroxymethylglycinate

Sodium hydroxymethylglycinate (CAS 70161-44-3) is a formaldehyde-releasing preservative used in personal care and industrial formulations.

Where is Sodium hydroxymethylglycinate used?

• Personal care: preserves rinse-off and leave-on formulations such as shampoos, conditioners, lotions and liquid soaps
• Water-based coatings and architectural paints: in-can preservative against bacterial and fungal contamination
• Adhesives and sealants: incorporated into water-borne systems where microbial degradation would compromise viscosity
• Industrial cleaning products and detergents: preserves emulsified systems
• It controls microbial growth in water-based systems, extending shelf life and protecting product integrity.

Good to know: Often combined with other preservatives to broaden the antimicrobial spectrum.

Commercial specifications

• Aqueous solution, typically around 50% concentration
• Packaging: drums and intermediate bulk containers
