Uses
spermatocide, contraceptive
Description
The general formula of nonoxynols is
C9H19C6H4(OCH2CH2)nOH. Each nonoxynol is characterized
by the number (n) of ethylene oxide repeated in
the chain. They are present in detergents, liquid soaps,
emulsifiers for creams, fabric softeners, photo graphie
paper additives, hair dyes, lubricating oils, spermicides
and anti-infective agents. They are irritants and
sensitizers.
Chemical Properties

Definition
ChEBI: Tergitol is a poly(ethylene glycol) derivative that is poly(ethylene glycol) in which one of the terminal hydroxy groups has been converted into the corresponding p-nonylphenyl ether. It has a role as a nonionic surfactant. It is a poly(ethylene glycol) derivative and a hydroxypolyether.
Manufacturing Process
220 parts of isononylphenol prepared by condensation of phenol with an olefin mixture obtained by polymerization of propylene and containing essentially isononylenes are caused to react with 0.5 part of caustic alkali powder. The whole is heated to about 130°C to 135°C and the water formed is removed under reduced pressure, while stirring. Thereupon, ethylene oxide is introduced into the melt, while well stirring, during which operation care must be taken, that the temperature of the reaction mass is maintained between 180°C and 200°C. When about 300 parts of ethylene oxide are taken up, the reaction is interrupted. A water-soluble oil is obtained.
