Potassium Sorbate

Potassium Sorbate is the potassium salt of sorbic acid, widely recognized as one of the mildest and safest preservatives in cosmetics. It works by inhibiting the growth of yeasts and molds, making it particularly effective in water-based formulations, though its efficacy diminishes significantly above pH 6.5. Formulators favor it for its excellent safety profile, lack of formaldehyde release, and synergistic effects when combined with other preservatives, allowing for lower overall preservative concentrations in formulations.
