Sodium Salicylate
What is Sodium Salicylate?
Sodium salicylate is the sodium salt of salicylic acid, a naturally occurring compound found in willow bark and synthesized for commercial use. In cosmetics, it belongs to the category of antimicrobial agents and alcohol modifiers. As a preservative, it inhibits the growth of bacteria, yeast, and mold by interfering with their metabolic processes, thereby extending product shelf life in water-containing formulas like toners and serums. As a denaturant, it renders ethanol unfit for consumption to comply with regulations, while also aiding in smoother application and faster evaporation in sprays and mists. Its mild acidic nature allows it to contribute to pH balancing, supporting overall formula stability without aggressive effects.
