OEKO-TEX updates valid test criteria for 'Standard 100'
Jan '14
At the start of the year, the OEKO-TEX Association has, as usual, updated the valid test criteria and limit values for product certification in accordance with OEKO-TEX Standard 100. The following new regulations come into force on 1 April 2014 for all certifications, following a three-month transition period:
The specifications for perfluorooctanic acid (PFOA) will become much stricter. In future, values cannot exceed the following limits:
• Product class I: 50 μg/kg = 0.05 mg/kg (previously 0.10 mg/kg)
• Product class II: 100 μg/kg = 0.10 mg/kg (previously 0.25 mg/kg)
• Product class III: 100 μg/kg = 0.10 mg/kg (previously 0.25 mg/kg)
• Product class IV: 500 μg/kg = 0.50 mg/kg (previously 1.00 mg/kg)
• Four longer-chained, perfluorinated compounds will also be included in the criteria catalogue with the same limit values as PFOA. Specifically, these are the substances perfluoroundecanoic acid / heni-cosafluoroundecanoic acid (CAS 2058-94-8), perfluorododecanoic acid / tricosafluorododecanoic acid (CAS 307-55-1), perfluorotridecanoic acid / pentacosafluorotridecanoic acid (CAS 72629-94-8) and perfluorotetradecanoic acid / heptacosafluorotetradecanoic acid (CAS 376-06-7). 
The reason behind this is the inclusion of the chemicals in the ECHA Candidate List with substances of very high concern (SVHC) as part of the REACh legislation.
With these two measures, OEKO-TEX is specifically supporting the "Zero Discharge of Hazardous Chemicals (ZDHC)" initiative of international brands and retailers that have committed to excluding hazardous chemicals from the production process by 2020.
• All the perfluorinated compounds (PFCs) regulated by OEKO-TEX will in future be listed in a separate substance category, and not, as previously, in the section "Other Chemical Residues".
• For the alkylphenol ethoxylates (APEOs), the test will be extended to further ethoxylate chains (1-20). The limit values for nonylphenol (NP) and octylphenol (OP) as well as for nonylphenol ethoxylates (NP(EO)) and octylphenol ethoxylates (OP(EO)) will be significantly reduced in all OEKO-TEX product classes:
• Sum: NP + OP: 10.0 mg/kg (previously 50 mg/kg)
• Sum: NP + NP(EO)1-20 + OP + OP(EO)1-20: 250.0 mg/kg (previously 500 mg/kg)
• By reducing the limit values, OEKO-TEX® is contributing to the complete exclusion of NP and OP as well as APEOs from textile production, striven for by the industry and also one of the goals of the ZDHC initiative and other campaigns.
