PFOA represents the main salt of perfluorooctanoic acid and its ammonium, or "C8", and is an important raw material for textile "three anti-finishing agents". Perfluorooctanoic acid and its salts are also an organic pollutant which is difficult to degrade. It is highly persistent in the environment, and over time it also aggregates in the environment and accumulates strongly in human and animal tissues, both into the food chain. The potential risks to human health and the environment will be prolonged, but EPA needs more scientific information to assess the risks if it is to be banned or restricted; The EU has not yet made clear its position on perfluorooctanoic acid; But there are a lot of textiles in the world right now. Both companies and branded textile vendors have accepted the perception that perfluorooctanoic acid and its salts are potentially dangerous to human beings and the environment and explicitly prohibit perfluorooctanoic acid and its salts in their chemical restriction clauses. That is to say, perfluorooctanoic acid and its salts cannot be detected.
PFOS is known as perfluorooctanesulfonyl compound C8F17SO2XX, which is the abbreviation of perfluorooctane sulphonate. PFOS is mainly used in oil, dust, insecticide, surfactant, anti-fogging agent and so on. It is the main active component of antifouling agent for textile and leather products. PFOS, which is widely used in civil and industrial production, is the most persistent organic pollutant, which is not decomposed in concentrated sulfuric acid for an hour. Hydrolysis of perfluorooctane sulfonic acid at various temperatures and pH No obvious degradation was found. PFOS has good stability in both oxygen-increasing and anaerobic environments. A large number of studies using various microbes and conditions have shown that. There is no sign of any degradation of PFOS. The only case where PFOS is decomposed is incineration under high temperature. The EU has formally banned the use of PFOS in commodities. The first to be affected will be the textile, leather and other products of export enterprises. Because PFOS exists in the textile industry the widest range, any need to printing and dyeing as well as finishing of textiles need to undergo pre-processing washing. Other functions such as anti-ultraviolet, antimicrobial, etc. The additives used in finishing may also contain PFOS.The implementation of this directive will directly affect the export of textiles, leather, paper, packaging, printing and dyeing aids, cosmetics and other products in China.
APEO中包括：① 壬基酚聚氧乙烯醚（NPEO）：占80~85%；② 辛基酚聚氧乙烯醚（OPEO）：占15%以上；③ 十二烷基酚聚氧乙烯醚（DPEO）：占1%；④ 二壬基酚聚氧乙烯醚（DNPEO）：占1%。为了适合纺织品多功能整理的要求，有机氟类油性防水剂通常制成乳浊液或分散悬浮液，因此，需要使用一个合适的乳化剂来稳定，过去较多使用烷基酚聚氧乙烯醚，即APEO，其生物降解性很差，并呈现出较强的急性毒性，再加上它会分解产生烷基酚，烷基酚是一种禁用的环境激素，欧盟由2005年1月17日起明确规定禁用烷基苯酚聚氧乙烯醚（APEO）及烷基酚。
The APEO consists of: 1 nonylphenol polyoxyethylene ether (NPEO): 80%, 85%; (2) octylphenol polyoxyethylene ether (OPEON): more than 15%; 3 12 alkylphenol polyoxyethylene ether: 1%; DNPEON: 1. In order to meet the requirements of textile multifunctional finishing, organic fluorine waterproof and oil repellents are usually made into emulsion or dispersion suspensions. A suitable emulsifier is needed for stabilization. In the past, alkylphenol polyoxyethylene ether, or APEO, was used with poor biodegradability and showed a strong acute response. Toxicity , coupled with its decomposition to produce alkylphenols , is a banned environmental hormone , which has been explicitly banned by the European Union from Jan . 17 , 2005 , with the exception of alkyl phenol polyoxyethylene ether ( APEO ) and alkylphenol .
