Product Description

Product Description

Citric Acid Anhydrous

    Citric Acid Anhydrous is the purified, crystalline form of citric acid without water of crystallization. It shares the same chemical essence (C₆H₈O₇) and core functionalities as its monohydrate counterpart but is characterized by lower moisture content and higher chemical stability under dry conditions. This makes it the preferred form for applications where precise control over moisture, reactivity, or ingredient compatibility is critical, such as in anhydrous formulations, direct chemical synthesis, and moisture-sensitive products.

Application

Food & Beverage Industry

Pharmaceutical & Nutraceutical Manufacturing

Industrial & Technical Processes

    It serves as a highly stable acidulant, preservative, and flavor enhancer in dry food mixes (instant beverages, dessert powders, seasoning blends), where added moisture from the monohydrate form could cause caking or reduce shelf life. It is also used in fat and oil processing as a chelating agent to inactivate trace metals that cause rancidity.

    This is a key application. Its anhydrous nature makes it ideal for direct compression tableting of moisture-sensitive active pharmaceutical ingredients (APIs) and effervescent systems, where it acts as both an acid source and a disintegrant. It is also used in anhydrous ointments, creams, and powdered nutritional supplements.

    As a raw material in chemical synthesis, it is used in the production of citrate salts, esters, and other derivatives. Its defined anhydrous state ensures consistent reaction outcomes in processes where water content could interfere, such as in certain catalysis or polymer modification reactions.
