Glacial Acetic Acid FAQ | Common Questions & Answers

1. What is Glacial Acetic Acid?

Glacial acetic acid is anhydrous acetic acid with a minimum purity of 99.8%. It is a colorless transparent liquid at room temperature. When the temperature drops below 16.6°C, it will freeze into ice-like crystals, hence named “glacial”. It is the highest concentration of acetic acid and widely used in food, chemical, pharmaceutical and industrial fields as a core acidic raw material and solvent.

2. What is the difference between Glacial Acetic Acid and ordinary acetic acid?

The main difference lies in purity and water content. Glacial acetic acid has 99.8%+ purity with almost no water, featuring strong acidity, high activity and stable chemical performance. Ordinary diluted acetic acid contains large amounts of water and low concentration, only suitable for simple daily disinfection and cleaning. Glacial acetic acid is applicable for industrial synthesis, food production and high-standard manufacturing processes.

3. What are the grades of your Glacial Acetic Acid?

We supply two mainstream grades to meet different market demands:

Food Grade Glacial Acetic Acid: Complies with E260, FCC, Halal, Kosher standards, used for food seasoning, pickling, beverage pH adjustment and food preservative production.
Industrial Grade Glacial Acetic Acid: High purity with low impurities, used for chemical synthesis, textile dyeing, resin manufacturing, metal pickling and water treatment.

4. What is the purity of your Glacial Acetic Acid?

Our standard product purity is ≥99.8%, with ultra-low formic acid and heavy metal content. Each batch is strictly tested and delivered with a formal COA (Certificate of Analysis) to ensure stable and consistent quality.

5. Is Glacial Acetic Acid safe for food use?

Yes. Our food grade glacial acetic acid is a legal food additive approved by FAO, WHO and EU E260 standard. Under standard dosage, it is safe, non-toxic and harmless to human body. It is widely used in vinegar, sauces, pickles and beverage production worldwide.

6. What are the main applications of Glacial Acetic Acid?

Food grade is mainly used for food acidulation, flavor adjustment, preservation and beverage pH regulation. Industrial grade is widely used for vinyl acetate monomer (VAM) production, acetate chemical synthesis, textile printing & dyeing, pharmaceutical intermediates, industrial cleaning and wastewater treatment.

7. What is the freezing point of Glacial Acetic Acid?

The freezing point is 16.6°C. In low-temperature environments, the product will solidify into ice crystals. This is a normal physical phenomenon and does not affect product quality. After gentle warming and melting, it can be used normally.

8. How to store Glacial Acetic Acid properly?

Store in a cool, dry and well-ventilated warehouse, away from high temperature, fire and strong oxidants. Sealed storage is required to avoid volatile loss. The valid shelf life is 24 months under standard storage conditions.

9. What packaging do you provide?

We support standard export packaging: 220kg PE drum, 1000kg IBC tank and ISO tank bulk shipment. All packages are leak-proof, corrosion-resistant and suitable for long-distance sea transportation. Customized packaging is acceptable.

10. Is Glacial Acetic Acid a dangerous goods?

Yes, glacial acetic acid belongs to Class 8 corrosive dangerous goods. We have professional dangerous goods export qualification, complete MSDS and shipping documents, ensuring safe and compliant transportation and smooth customs clearance.

11. What certificates can you provide?

We can provide complete export documents: COA, TDS, MSDS, Halal, Kosher, ISO22000, HACCP, Food Grade Certificate and Origin Certificate, supporting global customs clearance and product registration.

12. Do you support free samples and trial orders?

Yes. We provide free glacial acetic acid samples for quality testing. Small trial orders and large FCL bulk orders are both acceptable, supporting long-term OEM and stable cooperation.
