Yes — SDA 40B is one of the standard ethanol grades for FDA-compliant hand sanitizer formulation under the OTC monograph. The denaturants make it eligible for tax-exempt purchase, which significantly reduces production cost versus undenatured ethanol. For FDA hand sanitizer monograph compliance, you'll need 60-95% ethanol concentration in the finished product (so 200 proof gets diluted with water/glycerin/other carriers), plus appropriate quality controls. Many commercial sanitizer brands use SDA 40B as the base.
