For latex to certified as organic, as with all organic products, it means that no chemicals or pesticides are used in growing the rubber trees, and up to the final production of the latex. For most, the primary concern is that no synthetics are used in the production of the latex. This type of latex is all natural and is certified as 100% natural rubber latex.
Make certain that current Oeko-Tex certifications are available when purchasing an all natural latex mattress. The Oeko-Tex certification will clearly state if the latex tested is 100% natural rubber latex, without synthetic content.
The 100% natural latex certification is very important, as high quality blended latex will also pass the Oeko-Tex Standard 100. We use this type of blended latex in our blended latex mattresses.
Oeko-Tex Testing Criteria
The internationally binding test catalogue according to OEKO-TEX® Standard 100 is based on scientifically proven parameters and is revised annually in line with the latest legislation and research.
1) Illegal substances such as carcinogenic colourants.
2) Legally regulated substances such as formaldehyde, plasticizers, heavy metals or pentachlorophenol.
3) Substances which according to current knowledge are harmful to health, but which are not yet regulated or prohibited by law such as pesticides, allergenic dyes or tin-organic compounds.
4) Parameters such as color fastness and a skin-friendly pH-value, which are precautionary measures to safeguard consumer health.
Overall the test criteria clearly exceed existing legislation and often have a pioneering function regarding legal regulations – such as the exclusion of carcinogenic azo dyes, the strict limit values for formaldehyde as well as the ban on allergenic dyes.
