I recently found out a make up product I use derives a fatty acid ETHYLHEXYL from an ethanol compound called 2-ethylhexanol, would that make my product haram?
Even if it was ethanol it would be permitted. Alcohol is only forbidden to use when it is consumed for its own sake and it has a chance of causing intoxication, so, for example, the alcohol in vanilla extract is halal because the point in using it is not to get the alcohol but the vanilla, and there is no chance of intoxication. Please see: Is alcohol in tinctures and drugs halal?
And God knows best.
