Benzoic Acid
Benzoic Acid is the simplest aromatic carboxylic acid and the parent compound of the benzoate preservative family.
It has the molecular formula C₇H₆O₂, a molar mass of 122.12 g/mol, and a melting point of 122 °C. The substance occurs naturally in cranberries, prunes, cloves, and cinnamon, as well as in the gum benzoin resin from which it takes its name.
Solubility in water is modest (about 3.4 g per litre at 25 °C), so direct use in fully aqueous systems is limited. In low-pH and fat-containing foods it dissolves well enough to act as an effective antimicrobial.
We source bulk Benzoic Acid from top China manufacturers for our partners, working with several of them. The manufacturers are in Shandong and Hubei. For this ingredient the minimum order is 500 kg and a 20-foot container takes 16 MT, and a smaller requirement can ship in a combined container with other ingredients.
Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades
Benzoic Acid takes several physical forms, each tied to an end use.
Technical flakes and crystalline lumps are the bulk grade for plasticizer, alkyd resin, and chemical-intermediate manufacture.
Food grade is a refined fine powder or small crystals meeting FCC requirements for residual toluene, halogens, and heavy metals.
Pharmaceutical grade complies with USP, Ph. Eur., and JP monographs and is a sublimed or recrystallised white powder for topical and oral formulations.
Applications
- Fruit-based products at low pH including jams, preserves, and fruit fillings
- Pickled vegetables, sauerkraut, and acidified condiments
- Margarine, fat spreads, and shortenings where oil solubility is needed
- Salted and marinated fish products
- Flavour systems and essential-oil blends as a co-preservative
- Topical antifungal ointments, classically as part of Whitfield's ointment with salicylic acid
- Pharmaceutical excipient in tablets, suppositories, and creams
- Cosmetic preservation in lotions, creams, and rinse-off products under ISO 22716
- Tobacco flavour casings
- Chemical intermediate for benzoyl chloride, benzoate plasticizers, and phenol
- Feedstock for caprolactam and nylon-6 in certain process routes

How We Help Source Benzoic Acid
Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Benzoic Acid out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Benzoic Acid together with other ingredients such as Calcium Propionate, Sodium Diacetate and Sodium Propionate into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
Benzoic Acid carries the European food additive number E210 and is authorised in Regulation (EU) No 1129/2011 at the same maximum levels as its sodium, potassium, and calcium salts. Use is restricted to defined food categories such as low-pH beverages, preserved fruit and vegetables, and certain sauces.
In the United States it is affirmed GRAS for direct food use up to 0.1 percent under 21 CFR 184.1021, and is also permitted as an indirect food additive in food-contact materials.
JECFA has evaluated benzoic acid and benzoates together as a group and concluded they share a common toxicological basis.
USP, Ph. Eur., JP, and BP all publish pharmacopoeial monographs. Pharmaceutical grade is widely used in pharmacopoeia topical antifungal preparations and as a buffering or antimicrobial excipient.
Manufacturing Process
Nearly all commercial benzoic acid is made by catalytic liquid-phase oxidation of toluene with air.
The reaction runs at 140 to 160 °C and 2 to 5 bar in the presence of a soluble cobalt or manganese naphthenate catalyst, with acetic acid often used as a co-solvent. Toluene conversion per pass is kept moderate to limit over-oxidation to carbon dioxide.
Crude product is separated from unreacted toluene, water, and catalyst by distillation. The residue is then purified by vacuum distillation or solvent recrystallisation to remove coloured byproducts and trace halogens.
Food and pharmaceutical grades are obtained by an additional sublimation or recrystallisation step that targets sub-ppm levels of phthalic acid and other oxidation byproducts.
