What are PFOA/PFOS/APEO?
PFOA stands for perfluorooctanoic acid and its ammonium-containing main salt,and is the abbreviation of English Perfluorooctanoic Acid. PFOA is a synthetic chemical that is usually an indispensable processing aid for the production of high-performance fluoropolymers.These high-performance fluoropolymers can be widely used in aviation technology, transportation, electronics industries,as well as kitchenware and other household products.When PFOA decomposes, it will be released in the environment or the human body, causing toxic harm to the environment and the human body. PFOA will remain in the human body for as short as four years and as long as half of a lifetime. Restrictions on PFOA are required in related products.
The full name of PFOS is perfluorooctane sulfonyl compound (C8F17SO2X),which is the English abbreviation of perfluorooctane sulphonate. PFOS is mainly used in oil repellent,dust repellent, insecticide,surfactant,anti-fogging agent, etc. It is a textile and The main active ingredient of antifouling treatment agents for leather products,it is widely used in the production of civilian and industrial products.PFOS is highly persistent and is a difficult-to-decompose organic pollutant.It will not decompose even after being boiled in concentrated sulfuric acid for an hour. According to relevant research,no obvious degradation was found in the hydrolysis of perfluorooctane sulfonate at various temperatures and pH levels;PFOS has good stability in both oxygenated and anaerobic environments, and can be used in various Extensive research on microorganisms and conditions shows that PFOS shows no signs of degradation.The only time PFOS decomposes is during incineration at high temperatures. Because PFOS is one of the most difficult-to-degrade organic pollutants at present,it has persistence,high bioaccumulation, multiple toxicity,and the ability to be transported to the environment over long distances. It not only causes respiratory system problems in the human body,but may also lead to the death of newborn babies, which leads to Global pollution is attracting increasing attention.
APEO is the abbreviation of alkylphenol polyoxyethylene ether compounds and is the main representative of widely used nonionic surfactants. APEO is made from alkylphenol as the starting material,KOH as the catalyst, and condensation by dropping ethylene oxide under a certain pressure and temperature.The ecological and environmental issues related to APEO have been debated for many years. APEO includes nonylphenol polyoxyethylene ether (NPEO) accounting for 80-85%,octylphenol polyoxyethylene ether (OPEO) accounting for more than 15%, dodecylphenol polyoxyethylene ether (DPEO) and dinonyl Phenol polyoxyethylene ether (DNPEO) each accounts for 1%.The world’s annual consumption of alkylphenol polyoxyethylene ethers (APEO) is 880 million pounds, of which more than 80% is nonylphenol polyoxyethylene ethers (NPEO).
Next, let’s talk about carbon six waterproofing agent. Carbon six waterproofing agent is also a fluorocarbon compound, so there will be fluoride in it, so it contains PFOA, PFOS,and APEO. However, according to the advanced version of OEKO-TEX Standard 100 on April 1, 2017, the limit value requirements for PFOA and PFOS are < 1.0 µg/m².LeMan Three-proof finishing agent EE-6001,EE-6002,C6 low-temperature finishing agent EE-6003L, C6 drying finishing agent EE-6006, C6 non-ionic finishing agent EE-6008,C6 anti-siphoning finishing agent EE-6010A,etc.Not contain PFOA /PFOS/APEO,which meets this environmental protection requirement and can meet export standards.
