◉ Introduction to Chlorinated Phenols
Chlorinated phenols refer to the chlorinated substitutions of phenol, including pentachlorophenol (PCP), tetrachlorophenol (TeCP), trichlorophenol (TrCP), dichlorophenol (DCP), monochlorophenol (MCP) and ortho- All isomers of phenol. When wearing textiles containing chlorophenol residues, chlorophenols will enter the human body through the skin and bioaccumulate, posing a potential threat to human health. Therefore, many countries have imposed strict restrictions on the amount of chlorophenol residues in textiles. .
Chlorinated phenol, as a common antiseptic, mildew proof and moth repellant ingredient in various auxiliaries and chemicals in the textile industry chain, has great risks, but as long as it is carefully analyzed, the source is controlled, and strict testing is required. It is possible to achieve the safety limit requirements of chlorophenols in textiles to meet the corresponding regulatory standards.
◉ Sources of Chlorinated Phenols
Pentachlorophenol (PCP) and tetrachlorophenol (TeCP) have bactericidal and antiseptic properties, which can effectively prevent the growth of fungi, inhibit the corrosion of bacteria, and prevent the occurrence of insect pests. It can be used as a preservative in the storage and transportation of wool, leather, wood, dyes, printing pastes and inks. It can also be used as anti-corrosion and mildew-proof stabilizer in textile printing paste. And chlorophenols may also exist as intermediates in the synthesis of certain dyes and remain in dye products. Some chlorophenols can also be present as impurities in the raw materials used in dye production.
◉ The Dangers of Chlorophenols
Some chlorophenols are toxic to aquatic organisms beyond a certain level and cause long-term adverse effects on the aquatic environment. Some chlorophenols are classified as endocrine disruptors and can affect estrogen levels and the thyroid gland and may even cause cancer. Some chlorophenols enter the body by inhalation or skin contact and are highly toxic if exposure levels are exceeded. And some chlorophenols, when burned, release notorious dioxin-like compounds that can cause lasting damage to the environment.
◉ Test Standard for Chlorophenols
