>SDA 40B in its pure form contains about 8% water and is 190 proof.

Actually, SDA 40B 190 proof contains 5% v/v water which is closer to

6.2% w/w water.

In it's pure form, SDA 40B is 200 proof and, by BATF regulations, does

not contain water.

The recipe for pure 200 proof SDA 40B is

Ethyl Alcohol = 100 gallons

denatonium benzoate, N.F. = 1/16 av. oz.

tert-butyl alcohol = 1/8 gallon

So, if I understand, your vendor is taking 190 proof SDA 40B and adding

10% w/w water. If that is the case, the alcohol that you are selling

contains about 16% w/w water.

BTW, your website says that your " Perfumers Blend " is not regulated for

shipping purposes. What does the material safety data sheet say is the

flash point? You may want to check because I think it will meet the

definition of a Class 1A Flammable Liquid and will be subject to DOT

and, of course, OSHA regulations.

Class IA -- Includes those having flash points below 73 degrees

Fahrenheit (22.8 degrees centigrade) and having a boiling point below

100 degrees Fahrenheit (37.8 degrees centigrade).
