Öko-Tex Standard 100, which specifies allowable levels of chemical substances known to be a health risk in textiles, has added several new items to the test list. The permissible limits are based on scientific fact and as an ongoing process are kept constantly under review. Phthalates Concurrently with the EU decision to restrict the use of certain phthalate compounds, used primarily for the plasticisation of vinyl polymers such as PVC, Öko-Tex has introduced a limit value of 0.1 per cent for the total amount of six phthalates (DINP, DNOP, DEHP, DIDP, BBP & DBP). The analysis is carried out on a hexane extract.
