Product Overview
30% Diluted Acetic Acid Food Grade is a clear, colorless vinegar concentrate formulated for direct and indirect food-contact applications. At 30% strength by mass, it delivers meaningful acidity — roughly six times the concentration of standard table vinegar — while remaining straightforward to handle, dilute, and meter into a process. This is the concentration food processors, condiment manufacturers, and beverage producers reach for when they need consistent acid strength without the corrosion concerns of higher-concentration acetic acid.
we distribute this product in our Taylor, TX warehouse and ship it daily in containers ranging from quarts to 330-gallon totes.
Why This Concentration
Thirty percent sits at a practical midpoint in the acetic acid lineup. It carries enough acid to do real work in preservation, pH adjustment, and cleaning — yet it's classified in Packing Group III for transport (per 49 CFR 172.101), which simplifies your logistics compared to concentrations above 50%.
If your process calls for light acidification or gentle cleaning, a 5% Acetic Acid Food Grade or 10% Acetic Acid Food Grade may be sufficient — and they ship with less stringent handling. For higher-acid pickling brines or faster pH drops, step up to 50% Acetic Acid Food Grade or 75% Acetic Acid Food Grade, keeping in mind the sharper corrosion profile and tighter PPE requirements those concentrations demand.
The 20% Acetic Acid Food Grade is a lighter alternative when you want a food-grade acid with less bite and simpler dilution math.
Chemical Profile
This product is a 30% aqueous solution of acetic acid (C₂H₄O₂, molecular weight 60.05, CAS 64-19-7). It presents as a clear, colorless liquid with a pungent, vinegar-like odor. The solution has a density of approximately 1.04 g/mL at 20 °C and is fully miscible with water, which makes dilution to any target concentration straightforward. These are our published product-data values for the 30% aqueous solution as shipped.
Industrial Applications
The food-grade designation and moderate concentration make this product a workhorse across several process categories:
-
Food Preservation — Acetic acid inhibits bacterial and fungal growth by lowering the pH of the surrounding medium. At 30%, it can be dosed directly into brine formulations for pickled vegetables, canned goods, and fermented products, delivering consistent acidity batch to batch.
-
Flavoring and Condiment Production — Salad dressings, sauces, and marinades rely on controlled acidity for flavor balance. A 30% concentrate lets manufacturers meter in precise acid levels without adding excessive water volume to the formulation.
-
pH Adjustment in Food Processing — Many food-processing lines require tight pH control during production — from dairy to canned goods. This concentration provides enough acid strength to shift pH efficiently while remaining manageable for in-line dosing systems.
-
Food-Service Cleaning — Diluted acetic acid is used as a cleaning agent on food-contact surfaces and equipment, where its natural origin and food-grade purity are an advantage over synthetic cleaners in certain operations.
-
Fermentation — In vinegar production and other fermentation processes, acetic acid serves both as a process aid and as the target end product. A 30% food-grade solution can be used to inoculate or adjust acidity during fermentation cycles.
Handling & Storage
This product carries the signal word Danger and the hazard statement H314: Causes severe skin burns and eye damage (per the product's GHS classification). Take that classification seriously.
Wear chemical-splash goggles, face shield, and chemical-resistant gloves (nitrile or butyl rubber) when handling. Use in well-ventilated areas or with local exhaust ventilation to limit inhalation of vapors — the pungent odor will tell you when ventilation is insufficient.
Store in compatible containers: HDPE, polypropylene, or glass. Acetic acid will attack carbon steel, copper, and most common metals over time. Keep containers sealed in a cool, dry location away from direct sunlight and heat sources. Avoid storage near strong oxidizing agents and strong bases, which can react exotherically with acetic acid.
Inspect container seals and labels regularly. Rotate stock as needed — this is a stable solution under proper storage, but good warehouse practice applies.
Hazmat & Shipping
30% Acetic Acid ships as a regulated hazardous material under DOT and IATA rules. Here are the classifications as they appear on every shipping document we produce:
-
UN Number: UN2790 (per 49 CFR 172.101)
-
Hazard Class: 8 — Corrosive (per 49 CFR 172.101)
-
Packing Group: III (per 49 CFR 172.101)
-
Proper Shipping Name: Acetic acid solution, with more than 10 percent and less than 50 percent acid, by mass (per 49 CFR 172.101)
Every shipment leaves our facility in DOT-compliant packaging with proper hazmat labels, markings, and shipping papers. We handle the placarding, documentation, and carrier coordination — you receive a compliant shipment ready to accept into your facility.
Documentation
A Safety Data Sheet (SDS) in English ships with every order. A lot-specific Certificate of Analysis (COA) is available for this product, confirming the concentration and purity of the batch you receive. If you need documentation before ordering, contact us and we will send it ahead of your purchase.
