The tiny amount of ethylbenzene seems to be to prevent the naphtha

Ok, that's wrong. The ethylbenzene is probably a contaminant left
over from the distillation of the naphtha.

Possibly. "Naphtha" is not a really specific term (other then it is a
hydrocarbon :-) but the specs read heavy naphtha which usually has a
boiling point of 90 - 200 degrees (C) and ethylbenzine has a boiling
point of 130 degrees (C).
