Sodium Citrate is a versatile, water-soluble salt commonly used in personal care and cosmetic formulations as a buffering agent. Derived from Citric acid, it plays a crucial role in maintaining the pH balance of a product, ensuring stability and prolonging shelf life. Sodium Citrate is particularly useful in formulations that include ingredients sensitive to pH fluctuations, such as Alpha Hydroxy Acids (AHAs).

Benefits of Sodium Citrate:

• pH Stabilization: Sodium Citrate helps regulate and maintain a consistent pH level in cosmetic and skincare products, preventing ingredient degradation.

• Improves Product Efficacy: Enhances the performance and longevity of active ingredients by preventing pH-induced breakdown.

• Synergistic with Citric Acid: Commonly used alongside citric acid to create buffer systems that maintain a pH range between 5.6 and 6.2—ideal for most skin and hair care formulations.

• Mild and Non-Irritating: Suitable for sensitive skin and does not contribute to irritation when used in recommended amounts.

How to Use Sodium Citrate:

• Buffer System: Combine Sodium Citrate with Citric acid in water-based formulations to form a stable buffer solution.

• Typical Usage Rate: 0.1% to 2% depending on the formulation requirements.

• Application Areas: Ideal for use in creams, lotions, serums, cleansers, AHA products, and shampoos.
