Significance and Use

Alcohol ethoxylates and alkylphenol ethoxylates are important surfactants in household and industrial cleaners. They may be used as either nonionic surfactants or sulfated and used as anionic surfactants. Careful control of the ethoxylate characteristics is desired as variations may result in either desirable or undesirable end-use properties.


1.1 These test methods cover the various test methods used to evaluate those properties pertinent to the characterization of alcohol ethoxylates and alkylphenol ethoxylates with respect to suitability for desired uses.

1.2 The procedures for sampling and analysis appear in the following order:
