Product Overview
Denatured Alcohol 190 Proof 3C is a high-purity industrial-grade solvent designed for demanding manufacturing and processing operations. This product consists of ethanol denatured with a specific chemical additive formulation to comply with federal regulations, making it completely unfit for human consumption. Alliance Chemical distributes this versatile liquid to support critical workflows in printing, electronics manufacturing, and chemical synthesis. Every shipment of Denatured Alcohol 190 Proof 3C is carefully managed to ensure consistent quality and reliability for our industrial clients.
The molecular backbone of this product is ethanol, represented by the chemical formula C2H6O and featuring a molecular weight of 46.07. By choosing a denatured alcohol formulation, industrial operators bypass the heavy excise taxes associated with pure ethanol while retaining the robust solvency characteristics required for extraction, cleaning, and coating applications. Alliance Chemical handles the logistical and regulatory complexities of sourcing this vital chemical intermediate, ensuring direct delivery to your facility.
Why This Grade
Selecting the 190 Proof 3C grade is critical for industrial applications where a specific denaturant system is required. The "3C" denaturing formula is chosen precisely because it avoids denaturants that might interfere with specialized chemical reactions, industrial coatings, or delicate solvent extraction workflows. Using an incorrect denatured alcohol formulation can lead to catastrophic manufacturing failures, such as poor coating adhesion, unwanted chemical side-reactions, or residue contamination on finished components.
Furthermore, the 190 Proof concentration, which contains approximately 5% water, offers distinct physical advantages over anhydrous 200 Proof options in specific settings. The minor water content stabilizes the formulation under certain thermodynamic conditions and reduces the rapid evaporation rate seen in absolute alcohol. Attempting to use a standard formulation when 3C is specified can compromise batch integrity, degrade raw materials, and invalidate industrial processing protocols, making strict adherence to this exact formulation mandatory.

Hazmat & Shipping
As a highly flammable liquid, Denatured Alcohol 190 Proof 3C is classified as a regulated hazardous material. It is officially designated as UN1987, Hazard Class 3, Packing Group II. The proper shipping name for this material is Alcohols, n.o.s. (Ethyl alcohol, isopropyl alcohol). The authoritative signal word is Danger. Alliance Chemical manages all compliance protocols under strict federal regulations to ensure the safe and legal transport of this product to your facility, coordinating with certified carriers.
The GHS classification designates this product with the hazard statement H225, indicating highly flammable liquid and vapour. To maintain a safe workplace, personnel must wear appropriate personal protective equipment (PPE) as specified by OSHA standards. This includes flame-resistant clothing, anti-static gloves, safety glasses, and adequate respiratory protection in poorly ventilated areas. Never expose this material to open flames, hot surfaces, or sparks. Static bonding and grounding are required during transfer.
Handling & Storage
Store Denatured Alcohol 190 Proof 3C in a cool, dry, well-ventilated area away from direct sunlight, heat sources, and incompatible substances such as strong oxidizing agents, acids, and alkali metals. Keep the container tightly closed when not in use. Compatible storage containers include stainless steel, carbon steel, and approved high-density polyethylene (HDPE) vessels. Avoid aluminum and certain plastics that may degrade when exposed to ethanol. Recommended storage temperatures should be kept within a moderate range, ideally below 77 °F, to minimize vapor pressure buildup and reduce the risk of accidental ignition.
