Sodium Citrate Dihydrate

Sodium Citrate Dihydrate (Trisodium Citrate Dihydrate)

Food-Grade Buffering, Stabilising & Sequestrating Agent

Catalog Number: ASC-1064

Overview

Sodium Citrate Dihydrate, also known as Trisodium Citrate Dihydrate, is a high-purity food-grade sodium salt of citric acid supplied as a white, odourless crystalline powder. It is widely used as a buffering agent, acidity regulator, emulsifier, and sequestrant in food, beverage, laboratory, and industrial formulations.

Its excellent water solubility, neutral to mildly saline taste profile, and reliable pH-adjusting performance make Sodium Citrate Dihydrate a preferred ingredient where controlled alkalinity, mineral chelation, and formulation stability are required.

Ausamics Sodium Citrate Dihydrate is manufactured under controlled quality systems to ensure consistent purity, particle quality, and batch-to-batch reproducibility.
