latex cores: How natural is "Natural"?

I'm interested in the natural latex cores this company has for my own bed building project:
 
How is "Natural" defined with latex beds though?  
 
With food, a product can be labeled "USDA Organic" if it is 95% organic and can be labeled "Made with organic ingredients" if it is 70% organic, but forfeit the USDA label.  Failing that, the merchant can label any ingredients on the back as organic, but must not have "Organic" displayed on the front of the box.
 
So with mattresses, I'm guessing their is a similar loop hole with listing ingredients and proportions and I'm wondering how much synthetics can be used in a latex mattress advertised as being rubber tree derived and still be called "Natural"
 
My goal is to avoid a product claimed to be "natural" but also made with synthetics such as SBR (styrene butadiene rubber), since when you are sensitive, even a small amount is bad.  I'm not concerned about the chemicals used in the vulcanization process (sulfur, zinc oxide and what not) nor do I wring my hands as to weather the rubber tree plantation is certified organic - I'm just trying to avoid the petrol.

I read a reference (not from the LI website) that said that even their 100% natural Talalay latex uses about 2% SBR. It seems I can no longer find it (laughing). I will post it here when I find it and change the post above as well until it is confirmed. There is also a few percent of other "non latex" ingredients either as part of the latex itself or used in manufacturing.

In the meantime, here is an interesting article from the PFA which is an association of polyfoam manufacturers which pretty clearly shows the superiority of Latex over poly in most categories. Coming from the latex "competition" I thought it was pretty interesting. http://www.pfa.org/intouch/pdf/v8n1.pdf

Aha, I found it .... it came from one of the sleepez sites here http://www.sleepezbeds.com/latex-buyers-guide.html

and the part I read is this "Talalay Natural latex is a blend of approximately 98% natural and 2% synthetic. The 2% synthetic is needed as a bonding agent in the "talalay" process, and obviously does not alter the fact that it is classified as 100% natural."

Some of this information is either not accurate or no longer accurate (such as Radium producing natural Talalay. Dunlopillo was the other company producing natural Talalay) but at that time at least he seemed to have cause to believe that the LI natural Talalay had about 2% SBR. This was the only reference I have seen about natural Talalay having any SBR content.

OK, thanks for the great info!  I think I can feel safe making a purchase from a LI product at least.  Still, I'm sadly unsurprised that a product labeled "100% natural" can have a few lbs of SBR in it, depending on the manufacturer.
 
Any merchants reading this who do not use SBR in their product might want to say so.
 
Trying to avoid products containing petrol, formaldehyde or trichloroethylene is quite a archeology dig these days.  Even food has it's FD&C dyes sourced from coal tar, not to mention saccharin derived from petrol and more petrol from BHA and BHT. Then of course, rancid vegetable oil in everything and mislabeling of "trans-fat free" products which can allow trans-fats by the gram or just contain loads of mono and di-glycerides due to label-law loopholes.
 
Small wonder auto-immune diseases aren't more prevalent.
