Ethyl alcohol is a polar protic solvent that replaces acetone, IPA and heptane on polar targets. Compare boiling points, VOC and HAP status, and which grade (200 proof, 190 proof, SDA 3-A, SDA 3-C, CDA 12-A) fits your process.

Bulk ethyl alcohol flashes at 55 F and its vapor sinks. Here are the storage, transfer, spill response, and legal disposal rules for 190 and 200 proof ethanol, including EPA D001 and TTB requirements.

A buyer’s guide to purchasing bulk ethyl alcohol: denatured vs undenatured tax treatment, 190 vs 200 proof, USP/FCC/reagent grades, drum, tote and tank truck formats, and what actually drives your quoted price.

SDA 40-B is ethyl alcohol denatured with denatonium benzoate and tert-butyl alcohol under 27 CFR 21.76. Formula, authorized uses, TTB permit rules and proof options for fragrance and personal care formulators.

Specially denatured alcohol (SDA 3-A, 3-C, 40-B) requires a TTB industrial alcohol user permit. Completely denatured alcohol such as CDA 12-A does not. Here is how to tell which category your process needs, and what each formula is authorized for.

190 proof ethanol is 95% alcohol with ~5% water; 200 proof is over 99.5% alcohol with under 0.5% water. Here is how to choose, and which denatured formulas exist at each proof.
