CosIng Definition: Stabilising the pH of an aqueous medium in a narrow range even if an acid or base is added. Altering and/or maintaining a cosmetic product's pH at the desired level.
Buffering agents maintain the optimal pH range of a cosmetic product, ensuring it remains safe and effective throughout its shelf life. By resisting changes in pH, they help protect active ingredients from degradation and prevent irritation from overly acidic or alkaline formulations.
