LEATHER STANDARD By OEKO-TEX OEKO-TEX Testing Standards: 2019

The OEKO-TEX Association released the latest LEATHER STANDARD by OEKO-TEX product certification standards and limit requirements at the beginning of the year.

The new standard will take effect in April 1, 2019 after the three month pition period.

Benzene has been listed under the "other residual chemicals" project, aiming at all product level limits < 5 mg/kg.

OEKO-TEX has started monitoring quinoline since 2018, and the current limit is set to < 50 mg/kg.

Four kinds of amine salts (see Appendix 5) were also included in the project to detect carcinogenic aromatic amines.

In the "standardization" process of the limited value requirement, < < requirement > is currently applicable to all limited values.

< p= >

From the very beginning, the strategy of OEKO-TEX is not waiting for legislation, but a pioneer in the field of consumer protection.

After the implementation of the above update, LEATHER STANDAR has met the requirements of the new "REACH appendix XVII CMR regulation" (the European Commission regulations (EU) 2018/1513). The regulations list 33 CMR (carcinogenic, mutagenic, reproductive toxicity) substances.

The regulation came into force in November 2018, but it has not been implemented since November 1, 2020.

In contrast, most of the substances have been monitored for many years in the OEKO-TEX standard directory.

Other new test items

Under the "extractable heavy metals" project:

Barium limit < 1000 mg/kg (all product level)

Limit of selenium < 100 mg/kg (all product level)

Under the project of o-phthalate two (Plasticizer), new material two methyl ester of o-phenyl two formic acid was added.

Siloxane D4, D5 and D6 have recently been classified as highly concerned substances.

Limit value < 0.1% (<1000 mg/kg; all product levels)

From the current point of view, silicone related organosilicon, organosilicon finishing, silicone coating, silicone printing, plasticizer samples, soft and three proofing finishing samples are available.

Newly monitored substances

Medium chain chlorinated paraffin MCCP

Carcinogenic nitrosamines and nitroso compounds

By taking the action of "monitoring", the OEKO-TEX Association will pay close attention to such substances in related textile materials and will conduct more detailed analysis.

More stringent limits:

Free and partially released formaldehyde: product level III < 150 mg/kg (currently 300 mg/kg)

• three (2 chloro ethyl) phosphate (TCEP): all product level < 10 mg/kg (currently 1000 mg/kg)

Solvent residue (NMP, DMAc, DMF): all product level < 0.05% (currently < 0.1%).

Short chain chlorinated paraffin SCCP: all product level < 50 mg/kg (currently 100 mg/kg)

Short chain chlorinated paraffin SCCP and medium chain chlorinated paraffin MCCP were added to the new project "chlorinated paraffin" under these two substances.

Flame retardant products: new material four water, eight boric acid two sodium.

The limit value is adjusted to: each substance < 10 mg/kg; SCCP<50 mg/kg; total <50 mg/kg.

Through the above many new regulations, the OEKO-TEX association continues to provide strong support for "zero emissions of harmful chemicals (ZDHC)" and "detoxification action".

In this way, OEKO-TEX has enhanced the awareness of the potential harmful substances in textiles and has played a leading role in protecting consumers effectively.
