Science
Mechanism of Action
This ingredient exerts its antimicrobial action by releasing propionic acid within slightly acidic environments. Propionic acid subsequently disrupts the cellular processes of molds and yeasts, interfering with their metabolic pathways and enzyme functions to inhibit growth and prevent product spoilage.

Stability
Potassium Propionate presents as a white, crystalline powder. A 1 in 10 solution typically exhibits a pH range of 7.5 to 10.5. Its preservative efficacy does not strictly demand an acidic environment, though its mechanism involves the release of propionic acid under slightly acidic conditions.

Safety Profile
The Cosmetic Ingredient Review (CIR) has not published a specific safety assessment for Potassium Propionate. However, the European Commission permits its use as a preservative in cosmetics and personal care products up to a maximum concentration of 2% (expressed as propionic acid). It is generally recognized as safe (GRAS) by the FDA for use in the food industry.
