Hey there, sorry for starting up an old thread, but I guess it is better than making a new thread.

I am beginning to venture towards non toxic extractions, but am unsure about the levels of purity of d-limonene and how much purity matters. As I see it, you will be salting your alkaloids out of the d-limonene and as a result the purity of your limonene shouldn't affect the overall purity of your extracted alkaloids. 

I have done some research and this d-limonene ebay seller seems to have a lot of information and a reasonable price.

But in the item description it says:

Is this normal for d-limonene?
