A large number of aliphatic alcohols have been studied to relate performance of the derived surfactants to structure and molecular weight. The alcohols were examined as sulfates, ethoxylates, and ethoxysulfates in heavy‐and light‐duty compositions. Clear points and surface tensions of aqueous solutions were determined. Cotton detergency was evaluated in a bench‐scale test by using artificially soiled test cloths. Foam performance was measured in a soil titration test. In general, excellent performance is observed with derivatives which have 70% or greater n‐primary alcohol content. The odd‐numbered alcohol derivatives contribute significantly to optimum performance.
