Dear Andrea,
my lab measured 3 sample of ethanol in the framework of an interlaboratory collaborative study among 11 labs in the world.
The 18O values and sample description are as follows:

15.7 0 Vs. V-SMOW - alcohol 95%
-1.4 0 Vs. V-SMOW- anhydrous synthetic alcohol
19.6 0 Vs. V-SMOW - anhydrous alcohol

Hoping this could help you.

Hello, 

I was wondering if anyone has attempted to determine the delta 18O signature of
10% formalin or 85% ethanol. If so, what values did you obtain?

Thank-you, 

Andrea
