a grid of 30 surfactants varying from c//8 to c//1//8 in carbon chain lenght and from 40 to 80 in ethylene oxide (eo) content were examined to determine the effect of molecular structure on the physical properties (density, melting point, solution viscosity) and performance properties (surface activity, detergency, hard-surface cleaning, foaming, wetting) of linear alcohol ethoxylates. results show that while physical properties are influenced primarily by eo content, both carbon chain length and eo content are important to performance. optimum carbon chain length is also shown to depend strongly on surfactant concentration.
