Product Description

Product Description

Sodium citrate is the sodium salt of citric acid, a naturally occurring organic acid found in citrus fruits like lemons and 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.

Sodium Citrate

Sodium Citrate is 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, it 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, it meets stringent USP/FCC/EP standards with ≥99% purity.

Frequently Asked Questions

What is the primary role of Sodium Citrate in cosmetics?
It primarily acts as a pH adjuster and buffering agent to maintain the stability of a formula, and as a chelating agent to neutralize metal ions that could cause oxidation.
Is Sodium Citrate safe for sensitive skin?
Yes, Sodium Citrate is known for its mild and non-irritating properties, making it suitable for all skin types, including sensitive and baby skin.
At what stage should I add it to my formulation?
Sodium Citrate is water-soluble and should be added to the aqueous (water) phase of your formulation.
What is the recommended usage concentration?
For simple pH adjustment, 0.1–2% is typical. For more complex buffering or chelating needs, concentrations between 0.5–3% are often used.
Does Sodium Citrate help with hard water issues in hair care?
Yes, as a chelating agent, it binds with minerals found in hard water, which helps surfactants perform better and leaves hair shinier and less frizzy.
Is this product compatible with vegan standards?
Absolutely. Our Sodium Citrate does not contain any animal-derived components and meets vegan formulation requirements.
