in the reported experiments, the wetting of cotton skeins by aqueous solutions of individual surfactants has been measured at various temperatures using the draves technique. an individual compound with a homogeneous polyoxyethylene head group is a more effective wetting agent than a poisson distribution mixture with the same average number of oxyethylene units. the wetting time at 1 g/l concentration is a measure of the wetting effectiveness of the surfactant, because it is roughly inversely proportional to the diffusion constant of the surfactant at that concentration. for materials 30 c or more below their cloud point, temperature increase causes an increase in wetting effectiveness. 4 refs
