Monosodium Citrate Product Overview

Monosodium citrate anhydrous is a functional citrate salt used as a buffering agent, pH regulator and formulation ingredient across food, beverage, pharmaceutical, personal care and technical applications. It offers controlled acidity and reliable buffering behaviour, making it suitable for formulations where stable pH adjustment and predictable processing performance are required.

At Citribel, monosodium citrate is produced in Europe using a fermentation-based citric acid process and refined to deliver consistent purity and performance across batches.

The product is supplied in anhydrous form, meaning it contains no crystal water. This supports moisture-sensitive formulations, improves storage stability and allows accurate dosing in dry blends, granules and effervescent systems.

Available Forms

Monosodium citrate anhydrous is available in two forms to match different processing requirements.

monosodium citrate anhydrous granular
monosodium citrate anhydrous Powder

Granular grades offer excellent flowability and controlled dosing in dry processing systems, while powder grades provide fast dissolution and improved dispersion in premixes and blends.

Key Functional Properties

Buffering and pH control

Monosodium citrate provides controlled buffering capacity and helps maintain stable pH levels in formulations where acidity must remain consistent during production and storage.

Controlled acidity

Compared with trisodium citrate, monosodium citrate provides a milder buffering effect and slightly acidic profile, which can be useful when balancing flavour or formulation stability.

Excellent water solubility

The anhydrous salt dissolves readily in water, forming clear solutions suitable for liquid products and reconstitution systems.

Reliable processing behaviour

Controlled particle size distribution supports predictable flow, mixing and dissolution behaviour during industrial processing.

FAQ – Monosodium Citrate

What is monosodium citrate used for?

Monosodium citrate is used as a buffering agent and pH regulator in food, pharmaceutical, personal care and industrial applications. It helps maintain stable acidity and supports consistent formulation performance.

Monosodium citrate has a more acidic profile and provides milder buffering compared to trisodium citrate. It is typically used when a lower pH or more controlled acidity is required.

Monosodium citrate anhydrous is the water-free form of monosodium citrate. It offers improved stability, precise dosing and is suitable for moisture-sensitive formulations.

Granular monosodium citrate provides better flowability and is easier to handle in dry processing systems. Powder grades dissolve faster and are better suited for premixes and applications requiring rapid dispersion.

Yes. Citribel produces monosodium citrate in Belgium through controlled fermentation using Aspergillus niger and supplies industrial customers internationally.

Yes. Citribel supplies monosodium citrate in bulk quantities, including powder and granular grades for industrial applications.

Yes, monosodium citrate is highly soluble in water and forms clear solutions, making it suitable for liquid formulations and reconstitution systems.

Monosodium citrate may be evaluated in starch-based thermoplastics and other bio-based polymers where controlled gas release is required. Performance should be validated in the intended polymer system.
