Sodium Citrate vs Citric Acid — Key Difference

While Citric Acid lowers pH, Sodium Citrate acts as a buffering salt that stabilizes pH in a target range. Used together, they form a highly effective buffer system for serums, creams, and gels — ideal for pH-sensitive actives like Vitamin C, AHAs, and niacinamide formulations.

Key Benefits & Cosmetic Applications

• pH Buffering: Maintains stable pH in cosmetic formulations, preventing degradation of sensitive actives
• Chelating Agent: Binds metal ions that can cause product instability, discoloration, or rancidity
• Emulsifier & Stabilizer: Improves texture and consistency in creams and lotions
• Acidity Regulator: Controls tartness and prevents spoilage in food and beverage applications
• Water Soluble: Dissolves easily in water — convenient for cold or hot process formulations
