Overview

Denatured Alcohol Proof C is a specially formulated ethanol-based solvent that combines ethyl alcohol with specific denaturants to render it unsuitable for consumption while maintaining its excellent solvent properties. This clear, colorless liquid serves as a versatile industrial chemical with a characteristic alcoholic odor, offering the cleaning and dissolving power of ethanol at a cost-effective price point for commercial applications.

Key Applications

As an industrial solvent, Denatured Alcohol Proof C excels in dissolving oils, resins, and various organic compounds, making it ideal for manufacturing processes and equipment cleaning. Its effectiveness as a surface preparation agent makes it valuable in pre-treatment operations before painting, coating, or adhesive application, ensuring optimal surface cleanliness and adhesion.

In laboratory settings, this reagent provides reliable performance for analytical procedures, extractions, and general lab cleaning tasks. The product also serves as an effective paint thinner and cleaning agent, offering rapid evaporation and excellent degreasing properties for maintenance and janitorial applications.

Safety & Handling

With a flash point of 13°C, Denatured Alcohol Proof C is highly flammable and requires careful handling procedures. Always use in well-ventilated areas away from ignition sources, open flames, and hot surfaces. Personal protective equipment including safety glasses, chemical-resistant gloves, and appropriate respiratory protection should be worn when handling this material. The autoignition temperature of 363°C provides guidance for safe heating operations.

Storage & Shelf Life

Store in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Use appropriate grounding and bonding procedures when transferring the material to prevent static electricity buildup. Keep containers away from oxidizing agents and strong acids. When stored properly in original containers, the product maintains its quality and effectiveness for extended periods.

Frequently Asked Questions

What is Denatured Alcohol Proof C and what is it used for?
Denatured Alcohol Proof C is ethanol rendered unfit for human consumption by the addition of denaturants and supplied for industrial and laboratory use. It is commonly used as a solvent, cleaner, degreaser, fuel for alcohol burners, and for surface preparation in coatings and adhesives.
How should I store Denatured Alcohol Proof C and what is its shelf life?
Store in a cool, well-ventilated area away from heat, sparks and oxidizers in tightly sealed, approved flammable-liquid containers. When stored properly, denatured alcohol is stable for about 1–3 years; consult the supplier Certificate of Analysis (CoA) for manufacturer-specific shelf-life guidance.
What safety precautions and personal protective equipment (PPE) are required when handling Denatured Alcohol Proof C?
Use in a well-ventilated area or fume hood and wear chemical-resistant gloves, safety goggles, and flame-resistant clothing; avoid inhalation and skin contact. Keep away from open flames, ground and bond containers during transfers, and follow the product Safety Data Sheet (SDS) for first aid, spill response, and fire-fighting measures.
What do the different concentrations of Denatured Alcohol Proof C mean and how do I choose one?
Concentrations refer to the ethanol content after denaturation and can vary by formulation; higher ethanol content typically gives stronger solvency and faster evaporation. Choose concentration based on the required solvent strength, evaporation rate and application recommendations from the technical data or supplier.
What documentation is available for Denatured Alcohol Proof C?
Suppliers normally provide a Safety Data Sheet (SDS) and, upon request, a Certificate of Analysis (CoA) and technical data sheet detailing composition and lot-specific testing. Obtain up-to-date SDS/CoA for regulatory compliance, transport and risk assessments.
How is Denatured Alcohol Proof C shipped and what packaging options are offered?
Denatured alcohol is transported as a flammable liquid under applicable hazardous-material regulations and is commonly packaged in 5–25 L containers, 200 L drums, and IBC totes. Exact UN number, packing group and transport documentation depend on formulation and jurisdiction, so consult the SDS and carrier for specifics.
Is Denatured Alcohol Proof C compatible with common materials and equipment?
It is compatible with stainless steel, glass and many metals, but can attack or swell certain plastics, elastomers and coatings; compatibility depends on material grade and exposure. Test seals, gaskets and pump components for chemical compatibility before prolonged use and consult supplier compatibility charts.
What are the typical technical specifications for Denatured Alcohol Proof C?
Typical values for ethanol-based denatured alcohol include a clear, colorless liquid with a characteristic alcohol odor, specific gravity around 0.79–0.81 g/mL, boiling point approximately 78 °C, and a low flash point consistent with Class 3 flammable liquids. Actual specifications vary by formulation—refer to the product CoA and technical datasheet for exact lot-specific numbers.
Which industries and applications commonly use Denatured Alcohol Proof C?
Industries include coatings and paints, adhesives, printing, electronics cleaning, laboratories and general industrial maintenance for degreasing and surface preparation. Typical applications are solvent cleaning, surface prep, fuel for laboratory burners and non-potable sample preparation.
How can I purchase Denatured Alcohol Proof C and what are typical availability and lead times?
Denatured Alcohol Proof C is available from chemical distributors in small containers and bulk quantities; availability and lead times depend on order size, location and regulatory requirements. Contact suppliers for pricing, minimum order quantities, export documentation and any purchaser verification required by local regulations.
