You did not do homework
In google type
ronsonol msds and then you find its chemical sheet:
http://doryventures.scen...ing/2018MSDSRonsonol.pdfThe content is:
Aliphatic hydrocarbon,Hydrocarbons, C7-C9, n-alkanes, isoalkanes, cyclics
This description is a very typical naphtha and widely used for the purposes, looks fine.
The only remark CYCLICS mean not ideal for our purposes but this usually is a limited % and therefore not a real problem. In the worst case some tiny amount of spice will not freeze precipitate, the rest will, so no real worry. All the common light naphtha's are like that, if you want better then you must look for lab grade products.
Another way for you to have found the answer yourself is to do a SEARCH in this forum, hit SEARCH and type ronsonol in the POSTS rule. Then you could have found numerous posts of people using it.
Be Sherlock, it's fun!
