CDA 12A

Chrome Diagnostics completely denatured ethyl alcohol formula 12A-1 consists of 200 proof USP grade anhydrous ethyl alcohol denatured with high purity N-Heptane according to 27 CFR part 21.

CDA 12A is typically used during the plant extraction process as a solvent and during the winterization / purification process assisting in the removal of fats and oils. This is an industry standard ethanol blend that has zero federal excise tax. Because n-Heptane has a higher boiling point than ethanol, it may be necessary to heat the evaporator to a higher temperature (+5-10° C). This product is not intended for human consumption.

All Completely Denatured Alcohol (CDA) is subject to TTB regulation
Shipments do not require any permit or approval from the TTB, but must be for an approved formula and for the uses allowed by 27 CFR 20.141.

CDA 12A safety information

Risk factors
Toxic by inhalation. Flammable, dangerous fire risk. TLV: 400 ppm in air.

Hazard Statement
Keep away from heat, sparks, open flames, and hot surfaces. No smoking. Keep container tightly closed. Ground/bond container and receiving equipment. Use explosion-proof electrical, ventilating, and lighting equipment. Use only non-sparking tools. Take precautionary measures against static discharge. Wash hands thoroughly after handling. Wear protective gloves and eye and face protection. IF ON SKIN (or hair): Remove immediately all contaminated clothing. Rinse skin with water. IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Seek medical attention. If eye irritation persists: get medical attention. If medical advice is needed, have product container or label at hand. Keep out of reach of children.

NFPA Hazard Classification
Health: 2 (Moderate) Materials that, on intense or continued (but not chronic) exposure, could cause temporary incapacitation or possible residual injury, including those requiring the use of respiratory protective equipment that has an independent air supply. These materials are hazardous to health, but areas may be entered freely if personnel are provided with full-face mask self-contained breathing apparatus that provides complete eye protection. Flammability: 3 (Serious) This degree includes Class IB and IC flammable liquids and materials that can be easily ignited under almost all normal temperature conditions. Water may be ineffective in controlling or extinguishing fires in such materials. Instability: 0 (Minimal) This degree includes materials that are normally stable, even under fire exposure conditions, and that do not react with water. Normal fire fighting procedures may be used.
