Product Overview

Citric acid anhydrous carries no water of crystallisation and assays not less than 99.5% on the dried basis. Compared with the monohydrate form it delivers higher available acidity and introduces no bound water, which makes it the standard acid source for effervescent tablets, powdered beverages and dry blend systems.

Technical Information

Main Applications

• Effervescent tablets, powdered drinks and dry blend formulations requiring a water-free acid
• Pharmaceutical tablets and excipients
• Compound acidulants and buffering systems
• Moisture-sensitive fine chemical formulations
• Cleaning and chelating formulations

Selection and Handling Notes

• The anhydrous form, containing no water of crystallisation, is the standard choice for effervescent and dry powder formulations. Substituting the monohydrate risks premature reaction with bicarbonate and product failure.
• Conversion reference: at equal molar acidity, 100 parts of anhydrous equals approximately 109 parts of monohydrate. Do not substitute on a weight-for-weight basis.
• The anhydrous grade is hygroscopic and requires moisture-barrier packing and humidity-controlled storage; caking may occur under high humidity.

What We Provide

• Matching the grade and mesh specification to your required standard (BP / USP / FCC / EP / GB)
• Verifying COA, MSDS and batch consistency before shipment, with third-party inspection arranged where required
• Consolidating multiple products in one container to lower the per-item minimum order quantity
• Assembling the documentation required for destination clearance and arranging booking and shipment

Information Required for Quotation

To quote accurately, please provide three items: (1) target specification (standard, mesh size or assay grade), (2) intended volume (per order and annual), and (3) destination port with trade terms (FOB, CIF or other). We will then match a suitable supply option and return a COA together with our quotation.
