Sodium Citrate – 500g

Sodium Citrate in Cosmetics and Soap Making

Sodium Citrate is the sodium salt of citric acid, commonly used as a chelating agent, pH regulator, and preservative in cosmetics, skincare, and soap making. It is water-soluble and plays a key role in stabilizing formulations.

Uses in Cosmetics & Skincare

1. pH Buffer – Helps maintain a stable pH level, preventing skin irritation in creams, lotions, and serums.
2. Chelating Agent – Binds with metal ions in water to enhance the effectiveness of preservatives and improve product stability.
3. Preservative Enhancer – Works alongside preservatives to prevent microbial growth and extend shelf life.
4. Moisturizing Formulations – Helps improve hydration by stabilizing emulsions in lotions and creams.
5. Mild Exfoliation – Due to its citric acid origin, it can offer gentle exfoliation in some skincare products.

Uses in Soap Making

1. Water Softener – Binds with metal ions (like calcium and magnesium) to reduce soap scum and improve lather.
2. Prevents Soap Curd – Keeps bar soap from becoming sticky or slimy when used with hard water.
3. Helps Reduce Soap Rancidity – Acts as an antioxidant, slowing down the oxidation of oils, which extends the shelf life of handmade soaps.
4. Improves Transparency in Liquid Soap – Helps keep liquid soaps clear and free of cloudiness.
