Pentachlorophenol

It is important.

Preservative

It can prevent fungal growth, inhibit bacterial corrosion, and prevent insect pests. Therefore, it is often used for storage and pportation of natural fibers such as cotton, wool and leather. It is also used as stabilizer for preservative and mildew proof printing paste in textiles.

However, a large number of domestic and foreign research shows that pentachlorophenol is a strong toxic substance. It has teratogenicity and carcinogenicity to human body. When it burns, it will release dioxin compounds, which will cause lasting damage to the environment.

The EU has specially formulated the "1999/51/EC directive" which restricts the use of pentachlorophenol in textile and clothing. It clearly defines: exporting to Europe.

And the limit of PCP on clothing should not exceed 0.5 mg / kg (infant products should not exceed 0.05 mg / kg).

According to statistics from Ningbo entry exit inspection and Quarantine Bureau, in the first 9 months of 2010, the total number of textile and clothing exported to the European Union in Ningbo totaled 29 thousand and 500 batches, which was 615 million US dollars, compared with the 27 thousand and 500 batches and 588 million US dollars in the same period in 2009, which increased by 7.3% and 6% respectively, showing a good upward trend.

At present, all European clothing brands have strict limits on the use of pentachlorophenol in textiles.

In view of this, the inspection and quarantine department recommends: first, restrict the use of pentachlorophenol at the source, and textile printing and dyeing factories can sign the undertaking with the auxiliaries to realize the textile chemicals with no pentachlorophenol at ease. Second, the printing and dyeing and auxiliaries should adopt close and sincere cooperation. When meeting the necessity of using mould proof and antibacterial agents, we can consider the use of the currently recognized non-toxic orthophenyl phenol instead of pentachlorophenol. Third, as the final check on the export products, the inspection and quarantine departments should also carry out effective and effective sampling of pentachlorophenol for the textile and clothing products exported to Europe, so as to prevent the EU from notified by the content of pentachlorophenol.
