Profiling a chemical, under this chapter, implies developing its fundamental characteristics: identity as well as bodily- chemical threats. Uses as well as operates will be described in the chapter 2. For teams of substances, as it holds true for nonylphenols and their ethoxylates, it is usually difficult for presenting exhaustive information for all the members of the group. In this chapter details normally focuses on the most representative participants of the team. Nonylphenols and also nonylphenol ethoxylate are both groups of chemicals, participants of the big households of alkyl phenols (AP) and also alkyl phenol ethoxylates (APE), respectively.
nonylphenol ethoxylate (NP) have a phenolic ring on which a nine carbon alkyl chain is connected. The various nonylphenols are distinguished by the position where the alkyl chain is attached to the phenolic ring and also by the framework of the alkyl chain (linear or branched). nonylphenol ethoxylate (NPE) arise from the response of nonylphenol with ethylene oxide (EO). The level of ethoxylation for commercially readily available ranges from 4 moles of ethoxylates (NPE4) to eighty miles of ethoxylates (NPE80) 
Industrial production of nonylphenols and also nonylphenol ethoxylate causes mixtures of isomers, having additionally contaminations like unreacted ethylene oxide, gycol ethers  Nonylphenols as well as nonylphenol ethoxylate are mostly used in industry, in grater quantities then various other participants of the APE family members  According to the Alkylphenols & Ethoxylates Research Council (APERC, 2002)  CAS number 84852- 15-3 is the most detailed of commercially offered nonylphenol ethoxylate. The CAS numbers 25154-52-3 as well as 04-40-5 are taken into consideration by APERC much less detailed with respect to the branching and also position of the nonyl group. Additionally, ‘linear, or typical, n-NP is tough to generate and also is therefore less most likely to be commercially pertinent’  For NPE, there are some CAS registration numbers certain to particular degrees of ethoxylates, nonetheless, all degrees of nonylphenol ethoxylate at gujchem might be made under the CAS number for poly-ethoxylates (CAS 127087-87-0), as long as they are integrated using polymerization response between NP and also EO, baseding on India.
