Sodium Formate

Sodium Formate is the sodium salt of formic acid, appearing as a white crystalline powder that is highly soluble in water. In cosmetic formulations, it serves primarily as a buffering agent to maintain pH stability, while also providing mild antimicrobial properties that can support preservation systems. Formulators value it for its excellent solubility, neutral impact on product texture, and ability to work synergistically with other preservatives without causing irritation at typical use levels.
