Sodium Hydroxymethylglycinate

Description

Sodium Hydroxymethylglycinate is a synthetic preservative and pH adjuster commonly used in personal care products and cosmetics. This water-soluble ingredient is derived from the amino acid glycine and formaldehyde, forming a stable compound that effectively inhibits microbial growth. Its primary function is to prevent the proliferation of bacteria, yeast, and mold in various formulations, thereby extending the shelf life of products.

The ingredient operates optimally in a pH range of 3.5 to 12, making it versatile for use in a wide array of skincare and haircare items. Sodium Hydroxymethylglycinate is particularly valued for its efficacy at lower concentrations compared to some traditional preservatives, typically used at levels between 0.2% and 0.7% in formulations.

While it offers broad-spectrum antimicrobial protection, this preservative has sparked discussions regarding its safety due to its potential to release small amounts of formaldehyde over time. However, when used within recommended concentrations, it is generally considered safe by regulatory bodies. Some formulators prefer it as an alternative to parabens or other controversial preservatives. It's important to note that individuals with sensitive skin or formaldehyde allergies may need to exercise caution when using products containing this ingredient.
