For you MSDS watchers, here are some base oils and additives with CAS numbers with descriptions: NOTE: The CAS numbers listed are not all inclusive of what is out there, but are basic CAS numbers. Mineral Paraffininc Base Oil - 64742-54-7; VI of +94 to 120, any group, is a generic CAS number for paraffininc base oils; Mineral Naphthenic Base Oil - 64741-96-4; VI of ~15. Mineral Aromatic Base Oil - 64742-03-7; VI of ~185. Hydrotreated paraffininc, heavy - 64742-52-5 Hydrotreated paraffinic, light - 64742-53-6 PAO's: 68649-12-7, 68037-01-4, 163149-29-9, 151006-63-2, 151006-62-1, 151006-60-9, 157707-86-3 with VII's of +155 or greater: Some PAO Producers: Chevron Phillips Synfluid PAO 4 cSt PAO Exxon Mobil SpectraSyn 4 cSt PAO INEOS Durasyn 164 4 cSt PAO Diester - 28472-97-1; VII's average +170. Polyol Esters: 68441-94-1, Pentaerythritol ester of heptanoic and isopentanoic acids 118685-29-3, Mixed pentaerythritol esters of isononionic and heptanoic acids 77-99-6, TrimethylPropane (TMP) 68515-47-9, 1,2-Benzenedicarboxylic acid, di-C11-14-branched alkyl esters, C13-rich 91050-89-4, Fatty acids, C8-10, triesters with trimethylolpropane (TMP) VII Copolymers - 127883-08-3 Additives: ZDDP Type Adds: 68649-42-3, XXXXX-46-6. Calcium Sulfonates: 61789-86-4 Moly Dithiophosphate - 68958-92-7 or 68958-92-9 Moly Disulfide Powders - 1317-33-5 Here is what happens: EM, Chevron or Shell or whomever will come out with an oil (hydrotreated, isomerized, etc) and have it CAS registered with a different (new) number. I.E., New oils produced under a specific process may have new CAS numbers. However, CAS numbers do not necessarily equate to the specific process type. Some CAS Numbers for Group III hydrocracked hydroisomerized Group III 178603-64-0, 178603-65-1, 178603-66-2 The designation of Paraffinic, Naphthenic, or Aromatic simply describes the structure of the oil molecule. It has nothing to do with waxes, solvents, or being smelly. And let's remember that MSDS are Safety Data Sheets and do not reflect the actual formula, only what the Manf. has to declare for safety reasons.

What if the SDS says non-hazardous materials for up to 99% of the volume. What is a non-hazardous base oil? PAO, ester, straight clear mineral oil? I have always wondered because you see this designation a lot in synthetic oil SDS sheets.

Can you point to a specific example?

https://w3apps.phillips66.com/NetMSDS/ViewPDF.aspx?fileName=829143&Language=EN&IssueDate=7%2F2%2F2015&SubFormat=USDS I have come across others with this non-hazardous designation since I've joined the site but will have to do some more research to find them again. Seems that mostly ester based products, whether motor oil or refrigerants or building blocks for drugs/plastics etc. have this non-hazardous or no known hazards stipulation on their sds sheets. I pointed out that I used a charcoal lighter fluid the other night that was ester based with alcohol and smelled fruity/grape like/ winey like other ester products I have come across.

Haha, I pointed that out to some here and I think I hurt their feelings. They acted like they knew a secret formula for a product "because the SDS lists the ingredients".

good info for sure + it seems specific specs are getting less all the time as oil blenders would sooner spend on advertising than a better formulated product. i also see where specs used to come up but no more.

The other compounds, 1 and 3 are anti-oxidants and can be skin irritants to sensitive individuals. The middle one is an intermediate compound used in processing or the making of other materials and compounds. The other 99% of the ingredients are deemed non-hazardous and they are under no responsibility to tell you what they are, since the formulae are proprietary.
