Ok this is my first post so ...
SWIM found a solvent witch says it is light "hydrogenated or hydrotreated i cannot translate accurately "? odorlesss naphtha evaporation test was ok (it doesn't say exactly ingredient's though) (maybe it contains benzene) is this ok to use it is sold as a cloth cleaner.(lazyman's tek)
and how much time will 200ml of light naphtha take to evap aproximately?

Sorry for making a new thread "newbie"
could be usefull if there could be some country specific clues though
EINECS number of the solvent is : 265-151-9

Regular naptha evaps about 100ml per 30-40mins under a fan, and swim believes the light hydrocarbons are the ones to use.

Is SWIMs question stupid or you need aditional info ?

I don't think anyone can give a definite answer based on the given information. If it evaporated cleanly and separates from water, SWIM would try using it on a small batch.

i found also the cas number it is 64742-49-0

From what I can see your naptha is fine, an MSDS for the cas no above shows this.
