Preservative

Benzoic Acid

Production: Oxidation of toluene; also occurs naturally in cranberries and prunes
Activity: Broad-spectrum antimicrobial, most effective below pH 4.5
E number: E210
Compliance: FCC, USP, BP/EP, E210

Benzoic Acid is a broad-spectrum antimicrobial organic acid, produced industrially by the oxidation of toluene and also found naturally in cranberries and prunes. It is especially effective under acidic conditions below pH 4.5, inhibiting mould, yeast and certain bacteria, and it also serves as a precursor for plasticisers, alkyd resins and pharmaceuticals. Three particle grades are offered, and the choice between them decides dissolution speed, dust level and release behaviour.

Why buyers specify this grade

Three particle grades, fine powder, granular and coarse, so dissolution and dust are matched to the process
Fine powder 20-100 micron for rapid dissolution and high surface reactivity
Granular 0.2-1.0 mm with controlled release in water of 5-15 minutes and excellent flowability
Coarse 0.8-2.5 mm with low dust and slow release of 20-40 minutes for silos and hoppers
Food-grade, non-GMO and compliant with FCC, USP, BP/EP and E210 requirements

Problems it solves

Dust exposure in silo and hopper handling, addressed by the coarse low-dust grade
Slow dissolution holding up a liquid food line, addressed by the fine 20-100 micron powder
Segregation in a dry blend, addressed by the free-flowing granular grade
Regulatory documentation gaps, since the material is compliant with FCC, USP, BP/EP and E210

Packing and options

Custom mesh size across the fine, granular and coarse grades
Custom packaging on request
Technical documentation including MSDS and COA available on request

How it compares

Sodium benzoate is the water-soluble salt and is easier to dose into a liquid; benzoic acid is the undissociated acid form, which is what is active below pH 4.5 and what suits dry blends, feed and polymer applications. Within benzoic acid, the fine powder dissolves fastest and the coarse grade handles cleanest in bulk equipment.

Handling and storage

Use in products below pH 4.5 where antimicrobial activity is strongest
Pick the fine powder for liquid food and pharmaceutical suspensions, granular for dry blends, feed and seasonings, coarse for silo and polymer applications

FAQ

Benzoic Acid questions buyers ask

Which particle grades do you supply

Fine powder 20-100 micron, granular 0.2-1.0 mm and coarse 0.8-2.5 mm, with custom mesh sizes available.

At what pH does it work

It is a broad-spectrum antimicrobial that is especially effective under acidic conditions below pH 4.5.

What certifications do you hold for it

The material is food-grade and non-GMO, compliant with FCC, USP, BP/EP and E210, and certified HALAL, KOSHER, ISO9001, HACCP and GMP.

Which grade suits dry blending

The granular grade at 0.2-1.0 mm, which has excellent flowability and controlled release of 5-15 minutes in water.

Which grade has the least dust

The coarse grade at 0.8-2.5 mm, which is free flowing in silos and hoppers with slow release of 20-40 minutes.

Can I get custom packaging and documentation

Yes, custom packaging, mesh size and technical documentation including MSDS and COA are available on request.

Is it used outside food

Yes, in pharmaceuticals, animal feed as a mould inhibitor and acidifier, benzoate plasticisers, alkyd resins, corrosion inhibitors and personal care.
