Oeko-Tex Standard 100
(or Öko-Tex Standard 100) certifies the absence of harmful substances to health or the environment
in the finished product.
Its catalog of very specific criteria controls the chemicals that make up a garment and ensures it contains no formaldehyde , heavy metals or azoic dyes.Acceptability thresholds are imposed for pH, formaldehyde, heavy metals (arsenic, lead, cadmium, chromium, cobalt, copper, nickel, mercury, antimony), pesticides and herbicides, pentachlorophenol (PCP) and tetrachlorophenol (TCP), dyes known to be carcinogens or allergens, and chloro-organic carrieurs (to accelerate the dyeing).The tests carried out take into account the different ways chemicals can penetrate the body :
- Skin Absorption : Through an artificially triggered sweating process, the amount of existing substance detaching from the textile when the body perspires is measured.
- Ingestion : Ingestion of harmful chemicals plays an important part especially in the case of baby products.It is made of with tests using artificial saliva.
- Inhalation of harmful substances : The possible inhaling any harmful substances in the air is one of the Oeko-Tex tests covered by the laboratories using olfactometry and emission analysis.
