Trying to find a replacement for d-limonene but all i find is suspicious bottles
(swim is no chemist, just a simple baker).

Found this on the web and have asked the company for the MSDS but no reply.
Maybe someone you know have tried it.

it's supposed to be 98% Cold Pressed Orange Peel Extract and 2% emulsifiers (don't know what emulsifier means )

Thank you for your time!

welcome p simon. the best source that people on here have found is www.greenterpene.com

i remember reading that the orange peel extracts work alright but if they are just cold pressed, there may be some non-volatiles in the stuff. you may be able to redistill them to obtain limonene or atleast some volatile mix of orange peel stuff.

kinda know what an emulsifier is, i believe that they help to keep immiscible liquids together as an emulsion rather than seperated layers a.k.a. oil and water forced to stay mixed as their frothy combination when shaken rather than re separating.

i hope you enjoy our forums. the Music/Art/Literature is definitely my favorite section. that and the whole chemistry end of course. checkitout.

Don't use anything with emulsifiers added to it. Star dusts explanation is correct and they will interfere with sepertaing water and organic layer.

Ok! Good to know=)
To bad greenterpene wont ship north east=(...yet
Gonna skim the hardware stores in town, maybe something shows up.

Have a nice day!

What kind of non volatiles could be present in cold pressed orange oil?

Sugars, fatty acids, proteins etc.

So nothing really dangerous, i guess?
Would it work?

Well no nothing dangerous. Hmm well ok the sugars and other polar components would go into the water layer so they won't matter. But things like fatty acids would stay in the oil layer and contaminate your sample making recrystallization and perhaps even precipitation difficult maybe not possible. Proteins might also make some nasty emulsions same with the fatty acids.

But realize this is hypothetical I don't actually know whats in cold pressed orange peals I am just assuming that the above components would be there because they are in all plants and such a crude extraction would certainly contain them. Regardless I wouldn't use it as a solvent. Organic solvents should always be reasonably pure when doing these kinds of experiments. I wouldn't really recommend using distilled orange peels as they would contain various other essential oil components besides d-limonene although they would probably make less of a difference.

Good to hear!
My friend from peru would use it in conjunction with the san pedro tech 69ron described here. Jose would never use it to extract spice.

^^Oh well in that case if it worked for san perdo it should work for spice.
