If they are used in a condensing vapor degreaser neither will leave an "oily film". Methanol removes ionics better, isopropanol removes nonpolar materials better. Alcohols aren't the best to remove ...

I did a bit of research but could not find any source on solubility of these substances in ethanol. ChemSpider has some indirect prediction of the solubility of CBGA and GBDA in the form of a logP value. In a two phase system of water and octanol, substances with higher logP have a higher fraction in the octanol phase. Ethanol has a logP of −0.18, while the ...
