Since July this year, the European Union has implemented the 2009/425/EC directive, thus officially limiting the use of certain organotin compounds in consumer products. Directive 2009/425/EC stipulates that since July 1, 2010, the EU restricts the use of three butyltin and three phenyl tin compounds in all consumer goods, and the limit requirement is that the mass percentage concentration of tin content in commodities is less than 0.1%. If the detection exceeds the standard, the batch of consumer products will be returned and even severely recalled. 。

The organotin compounds concerned in this directive include three butyl tin, three phenyl tin compounds and two butyl tin and two octyltin compounds, of which the first two are formally restricted for July 1, 2010, and the latter two are in January 1, 2012. The above four organotin compounds are widely used in consumer products, such as the insole of shoes, antibacterial finishing of socks and sportswear, additives in the process of polyurethane foam production, stabilizers in the production process of PVC or catalysts in the production process of silicone rubber.

According to statistics, in the actual production process, the 10%~20% in tin production all over the world is used to synthesize organotin compounds. Moreover, organotin compounds are harmful to organisms and cause diabetes and hyperlipidemia.
