The production and use of nonylphenol and nonylphenol ethoxylates is prohibited for certain situations in the European Union due to its effects on health and the environment. [ 2 ] [ 51 ] In Europe, due to environmental concerns, they also have been replaced by more expensive alcohol ethoxylates , which are less problematic for the environment ...
Nonoxynols. Nonoxynols also known as nonaethylene glycol or polyethylene glycol nonyl phenyl ether are mixtures of nonionic surfactants used as detergents, emulsifiers, wetting agents or defoaming agents. The most commonly discussed compound nonoxynol-9 is a spermicide, formulated primarily as a component of vaginal foams and creams.
NP-40 (also known as Tergitol-type NP-40 and nonyl phenoxypolyethoxylethanol [1]) is a commercially available detergent with CAS Registry Number 9016-45-9. NP-40 is an ethoxylated nonylphenol for non-ionic surfactants and can act as emulsifier and demulsifier agent. NP-40 is often used to break open all membranes within a cell, including the ...
Alkylphenol. Alkylphenols are a family of organic compounds obtained by the alkylation of phenols. The term is usually reserved for commercially important propylphenol, butylphenol, amylphenol, heptylphenol, octylphenol, nonylphenol, dodecylphenol and related "long chain alkylphenols" (LCAPs). Methylphenols and ethylphenols are also ...
Fatty alcohol. Fatty alcohols (or long-chain alcohols) are usually high-molecular-weight, straight-chain primary alcohols, but can also range from as few as 4–6 carbons to as many as 22–26, derived from natural fats and oils. The precise chain length varies with the source. [1][2] Some commercially important fatty alcohols are lauryl ...
