D-limonene is this the real deal??

Probably, but don't quote me! :d I mean, it says food grade and high purity but did it say anywhere exactly what the purity is and if anything is added? I would look up the MSDS for it before making a purchase.
I use limonene A LOT and so I would highly recommend the following:
It is a bit more expensive for the gallon than the bay's but trust me, it works like a charm. They send you four 32oz bottles instead of one 1-gal bottle generally. It is 100% high purity food grade limonene. Nothing added whatsoever! And it smells soooooooo good!
Hope this helps

EDIT:
Just wanted to add, you can request the MSDS from the seller on amazon via email. I did that but seems like I deleted the email...
Anyway I sent another request and when the seller gets back to me I will post it here...for now, here is the complete description of the product:
Just don't use it on your cat apparently! :lol:
Anywho, good luck!

Terpenes & terpenoids, sweet orange oil CAS No. 68647-72-3
d-Limonene beta-Myrcene alpha-Pinene
91-95% 1-3% 1-2%
d-Limonene CAS No. 5989-27-5
See page 8 of http://www.epa.gov/HPV/pubs/summaries/monoterp/c13756tp.pdf
Will it work? IDK, for what? Cleaning your bath? Not sure if you want beta-Myrcene & alpha-Pinene in your solvent. You can read the toxicity analysis in the pdf.
Always ask for a MSDS and the specific CAS. The Grateful One's d-limo seems to be better.

Airdog, request the msds from Dafna auto. It's the only way to take the guess work out of the equation.
They do not have them publicly available, so you will have to contact them by email.
Better still, use grateful'is source

According to the CAS, this is dl-limo (138-86-3), not d-limo (5989-27-5). See Section 3: COMPOSITION/INFORMATION ON INGREDIENTS of the pdf.The Grateful One said:

Hmm, well that is interesting. Forgive me, as I am no chemical expert, but what is the difference between dl-limonene and d-limonene? I searched for the CAS number here:
www.commonchemistry.org
It listed dl-limonene and limonene as well as many other synonyms for that number. A similar list was found here:
Limonene
So is dl-limonene just a mixture of the d and l isomers of Limonene?
I think this may answer the question:
"Limonene, a colourless liquid abundant in the essential oils of pine and citrus trees and used as a lemonlike odorant in industrial and household products and as a chemical intermediate.
Limonene exists in two isomeric forms (compounds with the same molecular formula—in this case, C10H16—but with different structures), namely l-limonene, the isomer that rotates the plane of polarized light counterclockwise, and d-limonene, the isomer that causes rotation in the opposite direction. In the extraction of citrus juices d-limonene is obtained as a by-product, and it also occurs in caraway oil; l-limonene is present in pine needles and cones; dl-limonene, or dipentene, the mixture of equal amounts of the l- and d-isomers, is a component of turpentine.
Dipentene may be sulfurized to produce additives that improve the performance of lubricating oils under heavy loads; d-limonene is commercially converted to l-carvone, which has a caraway-seed flavour."

Well whatever it is I've got that is being sold as D-limonene, it works very well. Thank you for bringing this to my attention, Ufostrahlen!

Had to bring this thread back to life as I'm looking to find some d-limonene. I've found some sources but
I'm unsure which I need to get, does it have to be 100% food grade? Can I use industrial (pure grace)? or the essential oils like in the link?
Thanks in advance.

Boundary condition
I once purchased some orange oil and it was orange in colour. This means that it was an expressed oil rather than steam distilled and thus it contains impurities that would mess up extractions a bit. [It still worked for a cactus drytek, though.] So, if purchasing orange oil it's better to make sure it's distilled and not expressed. Lack of colour would be a useful indicator in this respect.
The sweet orange essential oil looks like an expensive way of buying impure limonene.
The orange oil terpenes look like they were at least steam distilled (and, incidentally, the listing contains a nice graphic of how to do it yourself) although they'll still be a mixture containing (the more reactive) myrcene and pinene.
Things sold as D-limonene or DL-limonene will (hopefully) be superior. Food grade is desirable as this gives more assurance that it will be free from harmful contaminants.
Limonene is a reactive solvent in that it slowly oxidises to carvone under extraction conditions and develops a spearmint/caraway odour. Carvone can react with primary amines and is a bit difficult to get rid of - your product will always carry a strange orangey/minty taste unless you work briskly while minimising contact with the air.

Hey limonene friends out there
I have some clear and colorless 95% D-Limonene at hand that's sold under the name "citric terpene". It doesn't have the usual orange smell but instead a nice lemon/citric smell...
I think it will do the job and I'll let you know in the future.
Anyone had d-limoene without orange smell, is it common?
