how can you tell the difference between natural and synthetic limonene and linalool?

[juicychops]

ive been reading up on it as a lot of organic products have these ingredients in them. how can you tell weather they have used the natural or synthetic version? or should i just assume its always the synthetic version?

i want products that are all natural - not synthetic substitutes

anyone?

I am allergic to a lot of ingredients and to limonene natural or synthetic. If you buy an organic product you cannot know because up to 5% of the ingredients can be non organic.
