Natural Dunlop Latex from Latex Green & Natural Talalay Latex from Latex International
FoamSource advises that, to protect yourself, you make certain that your mattress manufacturer can supply recent Oeko-Tex Certifications. The article tested must state "100% natural" (blended latex can also pass the same Oeko-Tex standards).
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.
It includes testing for:
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 colour 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.
