Sodium Formate
What is Sodium Formate?
Sodium formate is the sodium salt of formic acid, a straightforward organic compound typically produced through chemical synthesis from carbon monoxide and sodium hydroxide. In cosmetics, it belongs to the category of antimicrobial preservatives and pH adjusters. It works by releasing formate ions that interfere with microbial enzymes, preventing bacterial and fungal growth in formulations. As a buffering agent, it helps control acidity levels, ensuring the product remains stable and effective over time without fluctuating pH. This dual role appears in water-based products like lotions, serums, and cleansers, where it supports overall formula integrity at minimal levels. Its simple structure contributes to broad compatibility in diverse skincare recipes.
