Can chloroform be effectively stabilized with isopropanol? And why does ethanol stabilization usually only involve 1% by mass?

The oxidation of chloroform is dangerous because it results in phosgene formation under exposure to UV light. Along with the minimization of UV exposure, this reaction is usually prevented with 1%...
