Tri-Sodium Citrate is the sodium salt of citric acid, produced through the neutralization of citric acid with sodium hydroxide or sodium carbonate. Its chemical formula is:
It appears as a white, odorless crystalline powder with a mildly salty, tart taste, and is freely soluble in water. Recognized as GRAS (Generally Recognized as Safe) by the U.S. FDA and registered under the EU food additive code E331, it functions as a buffering agent, chelating agent, and emulsifier.
This makes it a preferred ingredient across food, beverage, pharmaceutical, and personal care formulations where stable pH control and high purity are essential.

Sodium Citrate is one of the most versatile buffering and chelating agents used across 6 major sectors. Its consistent purity and multi-functional profile make it effective across a wide range of formulation and processing conditions.
Sodium citrate acts as a buffering agent and acidity regulator in processed foods and soft drinks. Used as a flavor enhancer for beverages in citrus-flavored drinks, sports drinks, and instant drink mixes. Functions as an emulsifying salt in cheese production and dairy applications, preventing oil separation.
Used as a buffering and pH-stabilizing agent in syrups, tablets, and injectable pharmaceutical formulations. A key anticoagulant in blood collection tubes and blood storage/preservation applications. Functions as an excipient in drug formulations, particularly in effervescent tablets and soluble powder formulations, and as an emulsifier/stabilizer in pharmaceutical suspensions.
Acts as a pH balancing agent in skincare formulations, including facial cleansers, toners, and body washes. Improves stability in lotions and creams, shampoos, and conditioners. Commonly used in baby care products, toothpastes, and mouthwashes for its mild, non-irritating profile.
Functions as a chelating agent for water treatment, binding metal ions to soften water. Enhances scale-control and cleaning efficiency in industrial and municipal water treatment systems.
Used as a pH buffering agent in leather tanning, controlling metal ions during the tanning process to improve leather quality, consistency, and finish.
Acts as a water softening agent in detergents, boosting surfactant performance in laundry and dishwashing formulations. Also used as a processing aid in industrial cleaners and metal treatment applications.

Yes. Sodium Citrate is recognized as GRAS (Generally Recognized as Safe) by the U.S. FDA for use in food products, and all product components are listed on the U.S. EPA TSCA inventory.
Sodium Citrate (trisodium citrate) is registered under E331 in the EU food additive coding system, specifically E331(iii) for the dihydrate form used by Globex Venture.
Both grades typically meet a similar assay range (99–101%), but pharma grade is manufactured and tested against USP/FCC pharmacopeial standards for use in drug formulations, while food grade is qualified against food-additive standards (E331/FCC) for use in food and beverage manufacturing.
No. Sodium Citrate is not classified as hazardous under GHS and is not regulated for transport by ADR/RID (road/rail, EU), IMDG (sea), or IATA (air) — no UN number is required.
Under proper storage conditions — cool, dry, sealed packaging, away from moisture and direct sunlight — Sodium Citrate has a shelf life of approximately 24 months.
Yes. Globex Venture supports bulk and container-load orders as well as long-term supply contracts for food, beverage, pharmaceutical, and industrial customers across the USA, Europe, and Latin America, with full export documentation (COA, MSDS, TDS, Certificate of Origin).
