Synthetic leather base fabric：No Organotin Statement

Organotin is commonly used as an antimicrobial agent in textiles and leather products, and is one of the most widely used organometallic compounds. However, organotin has drawn much attention from the science community because of its toxicity and neurogenetic damage.

As the requirements for the ecological environment become more stringent, the types of hazardous trace elements are increasingly being included in the restriction list.

Currently, the OEKO-TEX Standard 100 (2021) and the Leather Standard by OEKO-TEX (2021) developed by OEKO-TEX® have quantitatively restricted 17 organotin compounds, recommending the use of gas chromatography-mass spectrometry (GC-MS) detectors.

Detection Limit Requirements

1、Oeko-Tex 100 regulations (mg/km): TBT, TPhT: type 1 products <0.5; type 2-4 products<1.0 Other 15 compounds: type 1 products <1.0; type 2-4 products <2.0 2、Attachment 17 of the SVHC list of REACH regulation stipulates that the content of all organotin: ≤ 0.1% (1000PPM) 3、Norway's "Prohibition of Specific Hazardous Substances in Consumer Products" PoHS stipulates that the content of tributyltin (TBT) and triphenyltin (TPT): ≤ 0.001 (in terms of mass percentage). In the production of artificial leather, we must effectively control every step of the process to prevent excessive organotin. As an excellent manufacturer of artificial leather base fabrics, our company strictly controls the dyeing process and solemnly declares that all the existing products can meet with the standards of organotin determination.
