I am in the process of purchasing a non Polar Solvent in a foreign country and I worry about the compositions of different products I am looking at. I have found a product which is marketed as extraction Naphtha from a company called DRAGON that states it doesn't contain benzene, which we know to stay away from. Below is the composition I found in the MSDS PDF for the product:
3.1 Substances
Name of the substance:
Light gasoline treated
Hydrogen (crude oil)
Index number: 649-328-00-1
CAS number 64742-49-0
EC number 265-151-9
mass line in% 100
A complex combination of hydrocarbons obtained by treating the petroleum fraction with hydrogen in the presence
catalyst. It consists of hydrocarbons having carbon numbers predominantly in the range of C4 through C11 and boiling
in the temperature range from approx. -20ºC to + 190ºC.
On the basis of note P, the substance is not classified as carcinogenic - benzene content <0.1%.
Toluene content <3% or n-hexane content <3%.
Does this look OK to use in a STB extraction?
Thank you

Yes, although it's still pertinent to do an evaporation test before use. βThere is a way of manipulating matter and energy so as to produce what modern scientists call 'a field of force'. The field acts on the observer and puts him in a privileged position vis-à-vis the universe. From this position he has access to the realities which are ordinarily hidden from us by time and space, matter and energy. This is what we call the Great Work." β Jacques Bergier, quoting Fulcanelli

I did an evaporation test in two separate petri dishes with my non polar solvent and at first glance it had completely cleared. However when I angle it very specifically in some light there is a slight outline. I heard whispers that this is normal, even if using water. However I wanted a `professional opinion` because I am taking the health aspect seriously. The pictures up close look more severe that what I see with my eyes bare in mind, as from my perspective its a barely noticeable. If this test fails then at this point, I will be looking at lab grade n-heptane. Juliusx33 attached the following image(s):  IMG_2183.jpg (2,310kb) downloaded 41 time(s).

So you've cleaned your petri dishes... Carefully distilling your OTC solvent is a good option if you don't want to order from chemical supply houses. βThere is a way of manipulating matter and energy so as to produce what modern scientists call 'a field of force'.

Ordered some reagent n-heptane. I did another test after cleaning the dish and to be honest it looked pretty fine to me. I mean from 9 angles out of 10, it was completely clean. In that one angle right under a lightbulb there was ever so faint signs of evaporation. The dish did not feel sticky to my finger and there was no smell. I am taking this as a sign that the solvent is okay to use. However, once I get my Reagent I will do another test and compare the two.
