Ethyl Alcohol
absolute
not denatured
This is the alcohol that humans can consume. A federal and local license is
required to sell such consumable alcohol. We do not have such a license and
do not want to get one. If you need alcohol that contains no denaturant, go
to your local liquor store and buy grain alcohol. It may be sold under another
name, but what you are seeking is 100% pure grain alcohol. Store in a poison
cabinet.

The catalase listing on this page is an example of how we provide more than
just “bare bones” catalog copy that tells nothing about a substance except
its name, package size and price. Flinn is the problem-solving supplier for
