What is Polyethylene glycol tert-octylphenyl ether?
The Uses of Polyethylene glycol tert-octylphenyl ether
Polyethylene glycol tert-octyl phenyl ether is formed by the polycondensation of octylphenol and ethylene oxide in the presence of an alkali catalyst. It is mainly used as liquid detergent, dye color improver or emulsifier in the textile industry.
Definition
ChEBI: Nonidet P-40 is a poly(ether) macromolecule that is polyethylene glycol in which one of the terminal hydroxy groups has been converted to the corresponding p-octylphenyl ether. A nonionic, non-denaturing detergent, it is used for solubilising membrane proteins during isolation of membrane-protein complexes. n ~ 8. It has a role as a detergent. It is an aromatic ether, a poly(ethylene glycol) derivative and a hydroxypolyether. It is functionally related to a 4-octylphenol.
