Sodium Citrate Multifunctional Cosmetic Ingredient Guide
01
Product Description
Sodium citrate is the sodium salt of citric acid, a naturally occurring organic acid found in citrus fruits (e.g., lemons, oranges). It functions primarily as a pH adjuster, chelating agent, and buffering agent in cosmetic formulations. Sodium citrate is synthesized by neutralizing citric acid with sodium hydroxide, and it is highly stable in aqueous solutions, making it suitable for a wide range of products.
Aogebio® presents Sodium Citrate, a versatile and high-purity cosmetic ingredient that serves dual critical functions in skincare formulations. As both an effective pH buffer and powerful chelating agent, our Sodium Citrate helps stabilize your products while enhancing their performance and shelf life.
Premium Applications Include:
• pH-sensitive serums (vitamin C, niacinamide)
• Preservative-boosted systems
• Anti-aging formulations requiring oxidative stability
• Baby care products demanding gentle ingredients
Available in both anhydrous and dihydrate forms, Aogebio® Sodium Citrate meets stringent USP/FCC/EP standards with ≥99% purity. Our technical team provides custom formulation support to help you optimize its multifunctional benefits in your products.
