Hi Phoenix,

Thanks for the reply

If you can link to the information you are referring to about being "moderately problematic" it would probably be helpful.


This quote is in the certificate itself

Hi MFC Memory Foam Comfort

This quote is in the certificate itself


As you mentioned ... the certificate indicates that 22 of the chemical substances they use are "Moderately problematic, but acceptable for use" and 1 is "Considered unassessed due to unknown identity or lack of toxicity information" but they don't provide any specifics or make any other comments other than that.

I would like to give some more explanation on the Material Health certificate.

Cradle to Cradle helps to (re)design products and processes to become safer, healthier and environmentally friendly. www.c2ccertified.org/

In the last few years Radium Foam has redesigned and improved Natural Talalay towards the Silver level. For receiving the Material Health certificate the product does not contain any banned materials and there are no carcinogens, mutagens, or reproductive toxins in the material. This is a good accomplishment.

Regarding the off-gassing requirements for Cradle to Cradle Gold certification.

Radium’s Natural Talalay meets the OEKOtex 100, Class 1 Standard. However, the OEKOTEX testing procedure does not cover all the VOCs required for C2C certification. Recently a VOC test that follows the AgBB Standard showed it meets all the off-gassing requirements for C2C Certification. Therefore, a new Material Health certificate will be available soon that shows the material meets VOC emissions.

Regarding Material Health and ABC-X requirements.
Cradle to Cradle assessments methodology first checks the potential hazard(s) of chemicals for both human and environmental health, and then an exposure assessment is applied. This basically means that for each exposure scenario (can be in production, use, recycling) it is checked whether the risk is considered significant or not. One example: one process chemical in rubber foam production is a chemical which is also found in a regular soap. This chemical is toxic to fish, however is not harmful for people and if it would be released to water it would biodegrade very quickly. Therefore this chemical is not considered to have a significant risk for the aquatic environment and it can be concluded that it is considered acceptable for use.
(In short, moderately problematic means the identified risk is not significant for the users and environment.)

The above might be quite technical. In summary, by receiving a Cradle to Cradle Health Certificate on the Silver level Natural Talalay meets stringent criteria and can be considered a safe material.

Hi Frieke Heens,

That's great news!

Another question that comes to mind (customers email me this question), is why is their no certified organic Talalay available?

Hi MFC Memory Foam Comfort,

Another question that comes to mind (customers email me this question), is why is their no certified organic Talalay available?


Some of the reasons are listed in my previous reply in post #4 here .

The requirement to separate production lines for blended Talalay and organic Talalay would probably be enough by itself for a company to decide not to produce organic Talalay given the very small market that it would have.

Now that Radium has the Cradle to Cradle Gold certificate which also covers some of the same criteria as organic certifications (such as social and environmental considerations) there would be even less reason to have an organic certification.

Hi Phoenix,

Thank you for giving me a few of your assumptions on why there is no organic Talalay. However I think I have found out why it can't be made. A client of mine emailed me this explanation after spending a month researching the subject. This does not take away any of the natural qualities and certifications of the Talalay latex, but simply puts my question to rest.

Stabilization of Rubber Latex
Though fresh rubber latex is nearly neutral and the rubber particles are stabilized by an adsorbed layer of protein and phospholipids, but on exposure to air the latex rapidly develops acidity and within 12 to 24 hours spontaneous coagulation sets in (at an approximate pH of 5). The latex has therefore, to be preserved immediately after collection against rise in acidity by bacterial putrefaction. As already mentioned, ammonia has long been used as preservative of latex owing to certain advantages including the ease of its removal by blowing air or reaction with formaldehyde. Other preservatives such as sodium pentachlorophenate, sodium salt of ethylene diamine tetraacetic acid, boric acid or zinc alkyl dithiocarbamates, may be used with smaller amount of ammonia. This is known as low ammonia latex and has the advantages of lower cost and elimination of the need to deammoniate the latex before processing into products.


source

Since there are no rubber trees in Europe or North America the rubber tree milk needs to be transported. Talalay is a complex process and is either processed in Europe, or in North America. Therefor technically it cannot be certified organic due to the fact the a stabilizer needs to be added to the rubber tree milk to prevent it from spoiling during transportation.
On the other hand Dunlop rubber can be certified organic because the rubber is processed on site (simpler process that Talalay) after tapping the rubber tree milk and does have stabilizers added.

I would really really appreciate comments from both Phoenix and Jeff Scheuer

Thank you
