Overview

Acetic Acid Glacial Food (CAS 64-19-7) is a high-purity, food-grade acetic acid with the molecular formula C₂H₄O₂. This clear, colorless liquid with a characteristic pungent, vinegar-like odor is an essential chemical for food processing, preservation, and various industrial applications. With a molecular weight of 60.05 g/mol and excellent water miscibility, this glacial acetic acid provides reliable performance across diverse manufacturing processes.

Key Applications

  • Food Preservation: Acts as an effective preservative and antimicrobial agent in food products, extending shelf life and maintaining product quality
  • Vinegar Production: Primary ingredient in commercial vinegar manufacturing, providing the characteristic acidic taste and preservation properties
  • pH Adjustment: Essential for controlling acidity levels in food processing applications, ensuring optimal product characteristics and safety
  • Pickling Agent: Used in pickling processes for vegetables and other food items, creating the acidic environment necessary for proper preservation

Safety & Handling

Acetic Acid Glacial Food has a flash point of 39°C and requires careful handling with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Ensure adequate ventilation when handling this chemical, as it has a vapor pressure of 15.7 mmHg at 25°C. The autoignition temperature is 485°C, and proper fire prevention measures should be implemented in storage and handling areas.

Storage & Shelf Life

Store in tightly sealed, corrosion-resistant containers away from heat sources and incompatible materials such as strong bases and oxidizing agents. Maintain storage temperatures below the boiling point of 118.1°C and above the melting point of 16.6°C to prevent crystallization. Keep containers in a cool, dry, well-ventilated area away from direct sunlight to maintain product integrity and extend shelf life.

Frequently Asked Questions

What is glacial acetic acid (food grade) and what is it used for?
Glacial acetic acid (CAS 64-19-7, C2H4O2) is the anhydrous, high‑purity form of acetic acid typically used where low water content is required. Food‑grade material is used as an acidulant, pH adjuster and processing aid in the food industry and also finds wide use in chemical manufacturing and laboratory applications.
How should food‑grade glacial acetic acid be stored and what is its shelf life?
Store in a cool, dry, well‑ventilated area away from heat, direct sunlight, strong oxidizers and bases in its original, tightly closed container; recommended containers include glass‑lined steel, stainless steel (316) or HDPE. When stored unopened under proper conditions, typical shelf life is about 1–3 years—refer to the supplier COA for exact expiry.
What are the key safety and handling precautions for glacial acetic acid?
Glacial acetic acid is corrosive and can cause severe skin and eye burns and respiratory irritation; always use chemical‑resistant gloves, goggles/face shield, apron and work in a fume hood or well‑ventilated area. Have emergency eyewash and safety shower available, avoid inhalation of vapors, and follow the product SDS for first‑aid and spill response procedures.
How do different concentrations of acetic acid affect use and hazard?
Concentration strongly affects acidity, vapor pressure and corrosivity: glacial is typically ≥99.5–99.9% while commercial concentrations range from dilute (5%) to concentrated (80%+) solutions. Higher concentrations are more corrosive and fuming and require more stringent PPE and packaging; dilute solutions are used where milder acidity is needed.
What documentation is provided when purchasing food‑grade glacial acetic acid?
Suppliers typically provide a Safety Data Sheet (SDS), Certificate of Analysis (COA), and Technical Data Sheet (TDS); food‑grade lots may also include statements of compliance with applicable food standards (e.g., FCC or supplier food additive declarations). Additional documentation such as lot traceability, halal/kosher certificates or custom QA reports can often be supplied on request.
How is glacial acetic acid shipped and what packaging options are available?
Glacial acetic acid is regulated as a corrosive material (UN2789) and must be shipped in accordance with local and international hazardous materials regulations (DOT/IMDG/IATA); shipping requirements vary by concentration and quantity. Common packaging options include laboratory bottles (1 L, 2.5 L), pails, 20–220 L steel or plastic drums, and 1000 L IBCs, with smaller pack options for retail/lab use.
What materials are compatible with glacial acetic acid and what should be avoided?
Compatible materials include glass, PTFE, PVDF, HDPE and stainless steels (e.g., 316 or glass‑lined vessels) for many concentrations; always verify compatibility for specific concentration and temperature. Avoid contact with strong oxidizers, strong bases, and certain reactive metals (e.g., some carbon steels, aluminum) which can corrode or react violently.
What are the key technical specifications for food‑grade glacial acetic acid?
Typical specifications include CAS 64-19-7, formula C2H4O2, molecular weight ~60.05 g/mol, purity typically ≥99.5–99.9% (w/w), density ≈1.049 g/mL at 20°C and boiling point ≈118.1°C. Exact impurity limits (e.g., aldehydes, water content) and analytical methods are listed on the COA and TDS provided by the supplier.
Which industries and applications commonly use food‑grade glacial acetic acid?
Common users include food and beverage processors (for acidulants and processing aids), chemical manufacturers (intermediates and solvent systems), textile and dyeing operations, surface cleaners and descalers, and laboratories for synthesis and analysis. Its combination of acidity and solvency also makes it useful in specialty chemical and formulation applications.
How can I purchase food‑grade glacial acetic acid and what should I expect regarding availability?
Food‑grade glacial acetic acid is available from chemical distributors in a range of pack sizes and concentrations; lead times depend on quantity, regulatory paperwork and shipping restrictions for hazardous materials. Request the SDS and COA when ordering, confirm packaging and transport requirements, and discuss minimum order quantities and pricing with your supplier.
