Frequently Asked Questions
What is sodium hydroxymethylglycinate used for?
Sodium hydroxymethylglycinate (CAS 70161-44-3) is used as a preservative in water-based personal-care, household, and industrial formulations to protect aqueous systems. It is the sodium salt of N-(hydroxymethyl)glycine and is supplied to formulators as a raw material.
What is sodium hydroxymethylglycinate made from?
It is derived from glycine (an amino acid) and formaldehyde, supplied as the sodium salt with molecular formula C3H6NNaO3. It is typically offered as an aqueous solution for direct addition to water-based batches. Refer to the SDS for handling and storage details.
What use-level and pH range is typical for this preservative?
It is a broad-spectrum preservative for aqueous systems and performs best in neutral-to-alkaline formulations; recommended use levels and pH ranges should be confirmed against the supplier data sheet and your own challenge testing. Request the technical data sheet with your quote for the specific lot specification.
How is bulk sodium hydroxymethylglycinate packaged?
It is commonly supplied as a liquid concentrate in drums, IBCs/totes, or bulk for manufacturers. Provide your target quantity and concentration to receive a bulk quote with a Certificate of Analysis and SDS.
What is the CAS number for sodium hydroxymethylglycinate?
The CAS number is 70161-44-3. Specify this CAS on your purchase order to ensure correct identity, since the name is sometimes confused with other glycinate or methylparaben-type preservatives.
