## Description

Quality Chemical Denatured Alcohol 190-1 gallon (128 oz.): desertcart.com: Industrial & Scientific

Review: First time finisher highly recommends. - Arrived promptly in a sturdy cardboard box. Jug lid seam was sealed with white tape, which I kept and used in re-sealing after use. The jug was inside a zip-loc slider-style bag (slider locked in place with more tape). I would think this could hold up to quite rough handling during shipping. This and the Old World Shellac flakes I ordered from desertcart combined to make a good, clean shellac. I'm french polishing for the first time, and it's going well. I wanted to choose the properties of my shellac solvent. I was unaware they also sell a 200-proof denatured alcohol, but I have noticed no clouding in my finish at all with the 190. See my answer in the Q&A portion for the chemistry. Smells like a bottle of alcohol from the liquor store, not paint-thinner-ish in the slightest. Spilled a little on my finger while pouring it and, like an idiot of course, touched the tip of my pinky to my tongue....GAH...revolting in minute quantities 'tis denatonium benzoate. I would opine that you can't get less toxic denatured alcohol than this unless you go the sin-taxed everclear route. January 2026 update: still have some of my initial gallon left & still works great for shellac. When I got it, it said it was SDA 40B a formulation defined in Title 27 cfr. I can't confirm this as of now on distributor's websites, which only refer to "denatured" alcohol with no type specification. Label on photo here includes "ethanol PM-3224" which is a variant of that likely including small amounts methanol and ethyl acetate & may include methyl isobutyl ketone and forms of naphtha. Unless specified, "denatured" is a vague term that includes denaturants either unfit for consumption or toxic.

## Questions & Answers

**Q: can this be used for perfume? Is the product its denatured with have an odor or warp the smell? Thank you**
A: Not recommended for perfume or personal care products. Does have a strong odor.

**Q: What are the denaturants and their concentrations?**
A: https://www.qualitychemical.com/shared/images/MSDS/ASH-460.pdf
unclear based upon msds from Quality Chemical but Ethanol SDA 40B 190 (CAS 64-17-5)
listed at two other manufacturers (Sasol and Sigma Aldrich) list it as containing
2-propanol, 2-methyl (CAS 75-65-0) or tert-Butyl alcohol
Sigma Aldrich further lists denatonium Benzoate (CAS 3734-33-6) as a bitterant.
I detected no "camphor" odor of tert-Butyl, but perhaps below sensory threshold.
Seems reasonable to conclude that Sigma Aldrich has the correct info.
One of the reasons I purchased it was low toxicity for wood finishing.  Superb choice for me.

**Q: can i mix this with water to make a disinfectant?**
A: Yes, if you mix 800ml of alcohol with 200ml of water in a spray bottle or bottle, it’ll be a good disinfectant. In many science labs they mix 700ml of this with 300ml water to make a 70% solution for cleaning benches and equipment. I use it to wipe my phone case, keys, car steering wheel, door knobs, and other surfaces. It should stay in contact with the surface for at least 1-2 mins before you wipe.

**Q: Does this leave any chemical residue behind once evaporated?**
A: It doesn’t, it drys clear.
