Product Overview
75% Vinegar is a concentrated aqueous solution of acetic acid (CAS 64-19-7) offered in Technical grade. It is a clear colorless liquid with a pungent vinegar odor — at 75% strength it behaves as a corrosive industrial acid, not a household condiment. Buyers include industrial cleaning and maintenance crews, water-treatment and process operators who need aggressive pH control, and facilities that prefer to stock one concentrated acetic acid and dilute down on site.
Pack sizes from 1 quart through 55 gallon drums and 275 and 330 gallon totes are available to order, so the same product covers bench work, plant maintenance, and bulk process supply.
Why This Concentration
At 75%, you are buying acid, not water. That matters two ways. First, freight and storage efficiency: every gallon delivers far more acetic acid than dilute strengths, so you handle fewer containers for the same acid demand and control your own working dilution. Second, reactivity: this concentration carries a Danger signal word and causes severe skin burns and eye damage (per the product's GHS classification), and it ships as a regulated Class 8 corrosive. If your process only needs mild acidity, a lower strength is the safer, simpler buy — see 10% Vinegar - Concentrated Industrial Strength for light cleaning work, or 30% Vinegar and 50% Vinegar for mid-range industrial jobs.
This listing is the Technical grade. Purchasing programs that require an ACS grade designation on the paperwork at the same strength should order 75% Vinegar ACS Grade instead. The Technical grade is the workhorse choice for cleaning, descaling, and pH adjustment where a grade designation is not specified on the purchase order.
Chemical Profile
75% Vinegar is a clear colorless liquid, supplied as a 75% aqueous acetic acid solution with a pungent vinegar odor. Acetic acid carries the formula C2H4O2 with a molecular weight of 60.05, under CAS number 64-19-7. The solution has a density of 1.069 g/mL at 20 °C and is fully water-miscible in practice, with published solubility of at least 100 mg/mL at 73 °F. Vapor pressure runs 11.4 mmHg at 68 °F and 20 mmHg at 86 °F — enough that open handling produces a sharp acid vapor, which is why ventilation is part of the handling plan below.
Industrial Applications
-
Industrial cleaning and descaling. Concentrated acetic acid dissolves mineral scale, lime, and alkaline residues on process equipment and hard surfaces. Crews typically dilute from 75% to a working strength matched to the soil and the substrate.
-
pH adjustment and control. As a moderate-strength organic acid, acetic acid brings down pH in process water and chemical baths with more forgiving dosing behavior than mineral acids. The concentrated form minimizes the water you add along with the acid.
-
Dilution stock. Facilities that consume acetic acid at several strengths buy 75% and blend down on site, cutting container count and freight events versus stocking multiple dilute strengths.
-
Laboratory reagent. Acetic acid serves as a general-purpose acid reagent in routine, non-critical lab work where a Technical grade material is acceptable.
Handling & Storage
Treat this product as the corrosive it is. The signal word is Danger, with hazard statement H314 — causes severe skin burns and eye damage (per the product's GHS classification). Acid-resistant gloves, splash goggles or a face shield, and chemical-resistant clothing are the baseline; work with ventilation adequate to keep the sharp acetic vapor out of the operator's breathing zone.
Store in a cool, dry area away from direct sunlight in compatible containers such as HDPE or glass. Keep it segregated from strong bases and oxidizing agents. When diluting, add the acid to water in a compatible vessel — never the reverse — and confirm every wetted material in your transfer path handles concentrated acetic acid before you pump it.

Hazmat & Shipping
This product ships as a fully regulated hazardous material. It is classified as UN2790, hazard class 8, packing group II (per 49 CFR 172.101), under the proper shipping name "Acetic acid solution, with not less than 50 percent but not more than 80 percent acid, by mass" (per 49 CFR 172.101). Our Taylor, Texas team packs it in UN-rated packaging with the required Class 8 labeling and shipping documentation. Receivers should be prepared to accept a placard-eligible corrosive at dock; if your site cannot receive Class 8 freight, resolve that before ordering.
Documentation
A Safety Data Sheet ships with every order and is available in English, Spanish, French, and Japanese. A lot-specific Certificate of Analysis is available for the material you receive, and a Technical Data Sheet is available for engineering and purchasing review. That paperwork trail matters for hazcom compliance, waste characterization, and internal QC intake.
Why Buy from Alliance Chemical
The practical reason first: this is a UN2790 packing group II corrosive, and shipping it correctly is our core work — every order leaves our Taylor, Texas warehouse in UN-rated packaging with Class 8 labels and SDS documentation handled by people who pack corrosives daily. Alliance Chemical has distributed industrial chemicals since 1998 and has served more than 50,000 customers, from single-quart lab orders to 330 gallon totes. Product pages like this one are reviewed by Andre Taki, DOT Hazmat Specialist, so the shipping and handling guidance you read matches how the freight actually moves.
