Benzoic Acid CAS:65-85-0

Benzoic acid (CAS No. 65-85-0) is a white crystalline powder with the molecular formula C₇H₆O₂. It is an important aromatic carboxylic acid compound with excellent antibacterial and preservative properties. It is slightly soluble in water and readily soluble in organic solvents, and is widely used in food, pharmaceuticals, and chemical industries. It is a commonly used environmentally friendly additive raw material.

Technical Grade

Technical grade Benzoic Acid suitable for chemical synthesis, plastics, rubber, coatings, and industrial applications. Minimum 99% purity with cost-effective performance for non-food manufacturing processes.

Food Grade

Food grade Benzoic Acid meeting international pharmacopoeia standards. Used as a preservative (E210) in food and beverages, as well as in pharmaceutical and cosmetic applications. Stricter quality control for heavy metals, arsenic, and organic impurities.

BP 2017 Grade

Pharmaceutical grade Benzoic Acid certified to BP 2017. Suitable for pharmaceutical formulations, topical preparations, and high-purity applications where pharmacopoeial compliance is mandatory.

Quick Comparison - All Grades

Note: "-" indicates the parameter is not routinely tested for that grade, or no limit is specified by the applicable standard. Contact us for detailed specifications if needed.

Food Processing: Used as a food preservative, suitable for soy sauce, vinegar, jams, beverages, pastries, meat products, etc. It effectively inhibits the growth of mold, yeast, and bacteria, extending the shelf life of food. Strict adherence to national standard limits is required.

Pharmaceutical Field: Used as a pharmaceutical intermediate in the synthesis of antibiotics, antipyretics, and analgesics; it can also be used directly as a topical disinfectant and antiseptic for disinfecting and inhibiting bacteria in superficial skin wounds.

Chemical Industry: Used in the synthesis of dyes, fragrances, plasticizers, etc. It is a core raw material for the preparation of sodium benzoate, benzoate esters, and other compounds, and is widely used in coatings, rubber, and other industries.

Other Fields: It is used as a cosmetic preservative to inhibit microbial growth in products; it can also be used as a feed additive to improve feed storage stability.

Dual independent raw material feeding system

Food-grade and industrial-grade raw material silos, feeding pipelines and reaction workshops are completely isolated with zero cross-channel connection. We never mix two grades at the source, unlike small factories that share one production line for cost savings.

Multi-stage rectification & recrystallization refining core process

We add 3 rounds of precise recrystallization filtration after the oxidation reaction to remove heavy metal, chloride and residual organic impurities step by step. This extra procedure raises our production cost moderately, yet keeps food grade heavy metal Pb ≤10ppm, far exceeding national standard limits. Competitors with simplified processes cannot achieve such strict impurity control.

Triple full-index online inspection before packaging

Every tank of finished materials will pass automatic online detection of purity, melting point, moisture and heavy metals; unqualified semi-finished products will be isolated and reprocessed immediately, unable to flow into finished goods. Each batch is sampled and stored in a constant-temperature warehouse for 3 years for traceability re-inspection.

One-stop complete batch-matched export certification service

Our factory holds full qualifications, including ISO22000, ISO9001, SC food production license, REACH registration and SGS testing capacity. Every shipment is accompanied by exclusive COA, MSDS and test reports corresponding to the batch number, no generic template files.

Flexible supply & professional technical support

Customizable 40/80/200 mesh particle sizes to match different production lines; free formulation dosage and pH adjustment technical guidance for all clients. We lock quarterly prices for long-term partners to avoid raw material price fluctuation risks.

Q1: Can food grade and industrial grade benzoic acid substitute for each other?

A: Never interchangeable. Food grade passes strict toxic impurity testing with full food safety certifications; industrial grade only fits chemical synthesis. Mixed usage leads to customs seizures and food safety violations.

Q2: How do you source high-quality products?

A: 1. Focus on key parameters in the Certificate of Analysis (COA) for each batch, such as purity and heavy metal content (Pb); 2. Request samples for testing prior to bulk purchasing; 3. Select experienced suppliers with relevant certifications

Q3: What documents are mandatory for EU food-grade benzoic acid export?

A: Batch-matched SGS report, REACH registration file, original COA, MSDS, ISO22000 & factory SC production license; all data corresponds to shipment batch code.

Q4: Which mesh size fits my production line?

A: 40mesh big crystal for solid preserved fruits; 80mesh standard for sauce & vinegar; 200mesh ultra-fine powder for juice, beverage & liquid cosmetics (fast dissolve, no precipitation).

Q5: Correct storage requirements for long shelf retention?

A: Store sealed in a cool, dry, ventilated warehouse below 30℃, humidity ≤60%, avoid direct sunlight. Unopened shelf life: 24 months.
