Citric Acid & Citrates for Pharmaceutical Applications

Reliable citric acid and citrate ingredients for pharmaceutical formulations, including effervescent tablets, powders, granules, syrups, oral solutions and buffer systems. Citribel produces citric acid, monosodium citrate and trisodium citrate in Belgium for manufacturers looking for consistent quality, reliable supply and technical support.

Citric acid, monosodium citrate & trisodium citrate for pharma

In pharmaceutical formulations, citric acid and citrate salts are widely used for pH adjustment, buffering, chelation and formulation support. They are applied across a broad range of dosage forms, from effervescent tablets and powders to syrups, oral liquids and buffered systems.

At Citribel, we produce citric acid and citrate ingredients in Belgium through a fermentation-based production process. Our portfolio supports pharmaceutical manufacturers and formulators looking for dependable sourcing, consistent product quality and ingredients suitable for regulated application environments.

With more than one citrate and citric acid format available, Citribel supports pharmaceutical applications where acidity control, buffering capacity, stability and processing consistency matter.

Functions of Citric Acid and Citrates in Pharmaceutical Formulations

pH adjustment

Citric acid is commonly used to modify the pH of pharmaceutical formulations and help create the desired acidic environment.

Buffering

Monosodium citrate and trisodium citrate are used as buffering agents to help maintain a stable pH range in formulations such as tablets, syrups and oral solutions

Chelation

Citric acid and citrate salts can bind metal ions, helping support formulation stability and limiting unwanted interactions that may affect product quality.

Effervescent functionality

Citric acid is often used in effervescent systems, where it reacts with carbonate or bicarbonate sources to create the desired effervescent effect.

Taste balance

In oral formulations, citric acid and citrates can also contribute to taste adjustment and a more balanced sensory profile, particularly in powders, chewables and liquid formats.

Liquid Solutions

Citribel offers citric acid in liquid form for customers who prefer a ready-to-use alternative to solid formats. Our liquid solutions can support easier handling, accurate dosing and direct integration into production processes, while maintaining the consistent quality expected from Citribel’s European production.

Pharmaceutical Applications

Citric Acid Anhydrous

Widely used in effervescent tablet formulations as the acidic component in combination with carbonate or bicarbonate sources. It supports controlled effervescence and formulation performance.

Citric Acid Monohydrate

Can be used in effervescent systems where specific formulation and processing requirements call for this form of citric acid.

Monosodium Citrate

Can be used in selected formulations where buffering capacity and controlled acidity are required.

Trisodium Citrate

Supports buffering and pH control in pharmaceutical systems and can be used where a more balanced acid-base profile is needed.

Citric Acid Anhydrous

Used in tablets, powders and granules as a pH regulator or excipient component depending on formulation needs.

Citric Acid Monohydrate

Provides acidity control in oral solid dosage forms and supports consistent formulation performance.

Monosodium Citrate

Acts as a buffering agent that helps regulate pH in solid pharmaceutical formulations.

Trisodium Citrate

Used to stabilise pH and support formulation consistency in tablet-based pharmaceutical applications.

Citric Acid Anhydrous

Suitable for powder and granule formulations where acidity, pH control or excipient functionality are required. Citribel also highlights controlled particle size and pharmaceutical suitability for its powder grade.

Citric Acid Monohydrate

Supports acidity regulation in pharmaceutical powders and granules while contributing to formulation consistency.

Monosodium Citrate

Provides buffering functionality and helps moderate acidity in dry pharmaceutical formulations.

Trisodium Citrate

Supports pH stability and contributes to balanced formulation design in powders and granules.

Citric Acid Anhydrous

Supports acidity adjustment in syrup formulations where pH and formulation balance are important.

Citric Acid Monohydrate

Provides acidity control and contributes to a stable formulation profile in pharmaceutical syrups.

Monosodium Citrate

Helps buffer acidity and improve pH control in syrup-based products.

Trisodium Citrate

Is widely used in pharmaceutical formulations including syrups, where it functions as a buffering and chelating agent.

Citric Acid Anhydrous

Used to adjust acidity and support formulation balance in oral liquid applications.

Citric Acid Monohydrate

Provides clean acidity and contributes to pH control in oral liquid formulations.

Monosodium Citrate

Acts as a buffering salt that helps regulate acidity and maintain a stable pH range in oral liquids.

Trisodium Citrate

Frequently used in oral solutions as a buffering and/or chelating agent.
