DESCRIPTION
SODIUM HYDROXYMETHYLGLYCINATE

Aqueous solution of sodium hydroxymethylglycinate. A broad-spectrum cosmetic preservative, effective against gram-positive and gram-negative bacteria as well as yeast and mold. Thanks to its high water solubility, it is compatible with most cosmetic formulations. This preservative is derived from glycine, a natural amino acid. It is active over a pH range of 4–12.

Practical formulation guide
Usage level: 0.2-1.0%
How to use and incorporate: Add according to its maximum temperature, usually during cool-down (below 40–45 °C/104–113 °F), dissolved or premixed in the phase indicated by the data sheet. Check that the final pH of the formula is within its effective range.
Formulation tips: Formulation guide: *Adding it to the water and then adjusting the pH to 6 before incorporating other ingredients can help avoid coagulation problems in gels. *It should be added to the formulation before adding salt, since sodium hydroxymethylglycinate can thicken some surfactant systems. *It may react with quaternary ammonium compounds, but this does not interfere with its function. Adding it below 60 °C/140 °F can help limit the coagulation caused by this interaction.
  • In products with carbomer, use at most 1 % and neutralize with the desired agent.
  • Preservation depends on the whole formula: validate the system with a microbial challenge test.
  • Organic acids (benzoic, sorbic, dehydroacetic) are only effective at acidic pH (approximately ≤ 5.5). Extracts, hydrosols, proteins and starches increase the demand for preservative.
  • Follow good manufacturing practices: purified water, sanitized utensils and clean packaging.
Compatibility: Check compatibility with nonionic surfactants, proteins and some polymers, which may reduce its effectiveness.
Storage: Keep in tightly closed containers in a cool, dry place, below 30 °C/86 °F.
Precautions: Non-irritating and non-toxic.
Technical information for formulators: This sheet describes industrial uses of the raw material in the development of cosmetic products. It is not an efficacy claim for any finished product. The person responsible for the formulation must validate the concentration, compatibility and claims of their product in accordance with applicable regulations.
