Acetic Acid: Properties, Uses & Price Trends in India

TL;DR: Acetic acid (CH3COOH) is a versatile industrial chemical used in textiles, paints, pharmaceuticals, adhesives, and food processing. This guide covers its properties, IS 695 grade specifications, what drives its price in India, and how manufacturers can source acetic acid from verified suppliers on OFB. 

Acetic acid is one of India’s highest-volume industrial organic chemicals, feeding textile dyeing, paints, pharmaceuticals, and food processing. The information covered here is for procurement and technical teams who need to understand acetic acid’s properties, grades, and pricing before placing a bulk order. OfBusiness (OFB), India’s B2B industrial procurement platform, connects manufacturers with verified acetic acid suppliers across 50+ raw material categories.

What Is Acetic Acid?

Acetic acid, also known as ethanoic acid, is a colourless organic acid with the chemical formula CH3COOH (molecular formula C2H4O2) and a molar mass of 60.05 g/mol. Its CAS number is 64-19-7, and it carries a sharp, vinegar-like odour.

Acetic acid’s IUPAC name is acetic acid itself, a retained name; its systematic IUPAC name is ethanoic acid. Its common name, derived from vinegar, is also acetic acid, though it is sometimes labelled ethylic acid or methanecarboxylic acid in older trade literature. At 100% concentration, water-free acetic acid is called glacial acetic acid, named for the ice-like crystals it forms when it freezes at 16.6°C.

Acetic acid is manufactured predominantly through the carbonylation of methanol, a process where methanol reacts with carbon monoxide under catalytic conditions. This synthetic route accounts for the majority of global production, though acetic acid also forms naturally through bacterial fermentation, which is how vinegar is made.

Where Is Acetic Acid Found?

Acetic acid is found in vinegar, where it makes up roughly 4% to 8% of the solution by volume alongside water. It is also present in trace amounts within the human body, formed during normal metabolism as acetate, a building block for lipids and other biological compounds.

Beyond these natural sources, acetic acid is present in a wide range of manufactured products. Examples include textile dyeing baths, paint and coating formulations, pharmaceutical buffer solutions, and food preservatives. In its concentrated glacial form, it is present in industrial processes as a solvent and chemical intermediate rather than a consumer-facing ingredient. Vinegar remains the most recognisable natural example, while industrial acetic acid is produced synthetically to meet the much larger volumes required by manufacturing.

Types of Acetic Acid Grades and Their Industrial Uses

Acetic acid sold in India is graded under IS 695:2020, which specifies three categories: Technical, Pure, and Analytical Reagent grade. Buyers should match grade to end use, since impurity tolerance and documentation requirements differ sharply between industrial and food or pharma applications.

Grade	Typical Purity	Standard Reference	Primary Buyer Use
Technical Grade	99.5%	IS 695:2020	Textiles, paints, adhesives, general industrial use
Pure Grade	99.5%–99.7%	IS 695:2020	Chemical synthesis, intermediate manufacturing
Analytical Reagent Grade	99.7%+	IS 695:2020	Laboratory testing, quality control
Glacial Grade	99.8%+	IS 695:2020 / ASTM D1208	High-purity chemical synthesis, pharma intermediates
Food/Pharma Grade	99.7%+ (FCC, IP/BP/USP)	FSSAI / Pharmacopoeia standards	Vinegar, food preservation, drug formulation

Industrial Applications of Acetic Acid

Acetic acid uses span multiple manufacturing sectors, each drawing on a different property of the chemical, from its acidity to its role as a solvent and synthesis feedstock.

Chemical synthesis and intermediates: Acetic acid is the primary feedstock for vinyl acetate monomer (VAM), acetic anhydride, and ethyl acetate. These derivatives feed adhesives, polymer production, and solvent manufacturing across India’s chemical industry.

Textiles and dyeing: Textile units use acetic acid to adjust dye bath pH to the 4–5 range required for acid dyes to bond effectively with nylon and wool fibres. Technical grade acetic acid is standard for this application.

Paints and coatings: Acetic acid functions as a solvent and raw material in paint formulations, thinners, and surface coatings, supporting consistent viscosity and drying behaviour.

Pharmaceuticals: IP, BP, or USP grade glacial acetic acid is used as a process solvent, in acetate buffer preparation, and as an intermediate in active pharmaceutical ingredient (API) manufacturing.

Adhesives and sealants: Acetic acid is a key input in adhesive formulations and bonding agents, particularly where vinyl acetate-based polymers form the adhesive base.

Food processing: Diluted acetic acid, typically 4–8% concentration, is the active component in vinegar, used as a preservative and condiment across the food industry.

A textile processing unit dyeing nylon fabric, for example, will typically specify technical grade acetic acid to hold the dye bath at the correct pH throughout the batch, since inconsistent acidity directly affects colour uptake and fabric quality.

How to Buy Acetic Acid?

Follow this seven-step process to reduce quality and compliance risk when ordering acetic acid.

1. Define the application and required grade. Confirm whether the end use needs Technical, Pure, Analytical Reagent, or Glacial grade under IS 695:2020.
2. Confirm food or pharma compliance where relevant. Food-grade buyers need FSSAI documentation; pharma buyers need IP, BP, or USP compliance records.
3. Request Certificate of Analysis (COA). A COA confirms assay percentage, colour (APHA), and impurity levels for the specific batch supplied.
4. Verify MSDS availability. Acetic acid is corrosive (UN 2789, Class 8); suppliers must provide a Material Safety Data Sheet before dispatch.
5. Check packaging compatibility. Acetic acid is compatible with HDPE and stainless steel; avoid aluminium packaging above 65% concentration.
6. Confirm price basis and lot size. Bulk tanker pricing differs substantially from smaller drum or carboy lot pricing; clarify which basis your quote reflects.
7. Confirm delivery and storage logistics. Acetic acid requires cool, dry, well-ventilated storage; align delivery timing with your facility’s storage capacity.

What Determines Acetic Acid Prices in India?

Acetic acid prices in India are driven primarily by methanol feedstock cost, since acetic acid is produced through the carbonylation of methanol and carbon monoxide. Import dependency, INR exchange rate movement, and domestic plant operating rates also shift prices through the year.

Key price drivers to track:

• Methanol feedstock cost: Since methanol is the primary input for the carbonylation process, rising methanol prices in Asia directly push up acetic acid production cost.
• Import dependency: India imports a share of its acetic acid requirement, particularly for glacial grade; port constraints and freight cost changes affect landed price.
• Domestic capacity: GACL and GNFC are among the country’s established glacial acetic acid producers; planned capacity additions can ease future price pressure.
• Grade premium: Glacial and Analytical Reagent grades command a price premium over Technical grade, due to tighter purity and documentation requirements.
• Lot size: Bulk tanker-load pricing runs substantially lower per kg than smaller drum or carboy packaging, which carries a distribution premium.
• Currency movement: INR weakness against the US dollar raises the cost of imported acetic acid and methanol feedstock alike.

As an indicative reference, OFB’s live pricing data shows imported acetic acid (Pharma Grade) at approximately ₹56 per kg, ex-Kandla, and imported Bulk grade acetic acid at approximately ₹56 per kg, ex-Mumbai, both indicative as of early July 2026, subject to market conditions. OFB’s platform data shows both reference points moved up over the preceding four days, by roughly 3.7% at Kandla and 1.82% at Mumbai, reflecting the short-term volatility typical of import-linked chemical pricing. Buyers should treat these as directional references and confirm current rates at the point of order, since acetic acid pricing shifts with methanol cost and import supply constraints on a near-daily basis.

All prices are indicative as of early July 2026, on an ex-warehouse basis as noted, and subject to market fluctuations. Contact OFB for current pricing.
