Natural Flame Retardant
Regarding flameproofing, we use wool and do not add other materials to the wool. In 2006, the CSPC enacted CFR 1633, which requires mattresses to pass an open flame test. A burner is placed on top of the mattress and the side for 60 and 90 seconds. After 30 minutes, the heat release must not exceed 200 kilowatts. The law does not require mattress manufacturers to use any flame retardants, but only pass the test. There are many companies, like Savvy Rest, Naturepedic, Lifekind, etc., use wool as the flame retardant and don't add other materials as well, but it is less common because wool can be 10 times or more expensive than a polyester and rayon flame retardant solution.
For wool, the typical chemical composition by weight is 50.5% carbon, 22% oxygen, 16.5% nitrogen, 6.8% hydrogen, 3.7% sulfur, and .5% ash which is potassium, sodium, calcium, aluminum, iron, silica, sulfate, carbonate, phosphorus pentoxide, and chloride. Please note that arsenic is naturally occurring compound in nature. It is found in water, appleseeds, soil, etc. When testing for VOCs and arsenic in wool in ppm, the quantity may not be detectable, but if measured in ppb, you may detect trace amounts in any wool even certified organic wool. Also, during its natural decomposition, the wool can release other chemicals into air. Unfortunately, I'm not well versed in this area.
Our wool is produced by the Woolgatherer and is certified to Okeo-Tex 100 - II. The certification number is 16.HUS.92223. Again, you may check to ensure the certification is valid on the Oeko-Tex website.
