◉ Introduction of Organotin Compounds
Organotin compounds are metal organic compounds formed by the direct combination of tin and carbon elements, which can be roughly divided into two categories: alkyl tin compounds and aromatic compounds, including tributyl tin (TBT), dibutyl tin (DBT), triphenyl tin tin (TPhT), tri-substituted organotin compounds such as tributyltin (TBT) and triphenyltin (TPhT), dioctyltin (DOT).
◉ Main Uses of Organotin Compounds
Catalysts, stabilizers, agricultural pesticides, fungicides and coatings and antifungal agents for daily necessities. In the natural environment, organotin compounds will react and decompose rapidly. Organotins are found in sealants, adhesives, catalysts, paints, coatings, PVC, outdoor fabrics, stabilizers, outdoor drainage pipes, gutters, appliances, textiles in contact with skin, gloves, shoes in contact with skin Fire parts, wall and roof coverings, child care products.
◉ Hazards of Organic Compounds
The substance can cause degeneration in female mollusks, reproductive toxicity in mammalian cells, and toxic and effects on the human nervous system, bile ducts, liver, skin and endocrine system.
◉ Why do Products Need to be Tested for Organotin?
The EU Regulation (EC) 1907/2006 Annex XVII on the Registration, Evaluation and Authorisation of Chemicals (REACH) sets out the prohibition of the use of organotin compounds, which is directly applicable to all EU Member States. Organotin compounds must not be used as fungicides/bactericides in coatings. In addition, they must not be placed on the market or used as antifouling substances: all vessels used in marine, coastal, estuarine and inland waterways and lakes; cages, buoys, nets and any other implements or equipment used for fish or shellfish farming ; any fully or partially submerged plant or equipment.
China's GB/T 18885 "Technical Requirements for Ecological Textiles" and GB/T 35611 "Green Product Evaluation Textile Products" both have relevant restrictions on the content of organotin compounds in textiles.
◉ Test Items
Including dibutyltin chloride, monobutyltin chloride, triethyltin chloride, triphenyltin chloride, tributyltin chloride, tripropyltin chloride, diphenyltin chloride Various mechanical compounds including tetrabutyltin, dioctyltin chloride and monophenyltin chloride are used for qualitative and quantitative detection, toxicology experiments and other testing items.
