This high-purity sodium citrate is a crystalline salt of citric acid, uniquely manufactured through a water- and energy-efficient fermentation process. By utilizing sugar molasses—a side-stream from sugar refineries—as the nutrient source for the fermentation fungus, this process transforms “waste” into a high-value functional ingredient.
Key Benefit: Supports a true circular economy by upcycling industrial by-products into a versatile stabilizer that reduces the environmental footprint compared to conventional fossil-based or resource-intensive routes.
Performance & Formulation Strategy
Sodium Citrate is favored for its ability to manage the delicate chemistry of water-based systems.
- Advanced Buffering Unlike citric acid, which aggressively lowers pH, sodium citrate is a conjugate base that stabilizes and “holds” the pH in the skin-neutral range of 5.5–7.0.
- Chelation & Sequestration: Binds to trace metal ions (like Calcium and Magnesium), preventing them from causing product discoloration, rancidity, or precipitation of other actives.
- Preservative Synergy: By sequestering minerals that microbes need for growth and preventing pH drift, it significantly boosts the performance of weak-acid preservatives.
- Skin Barrier Support: Helps maintain the skin’s acid mantle, reducing the irritation potential of surfactants and high-pH cleansing agents.
