Abstract
Studies on erucyl alcohol ethoxylated with 24 units and on behenyl alcohol ethoxylated with 21 ethylene oxide units gave values of 10·2 times 103 and 25·4 times 103 for the micellar weights, 74 and 203 for the aggregation number, and 134 and 106 moles water mole−1 surfactant for the micellar hydration, respectively. The solubilization of azobenzene, cortisone acetate, griseofulvin, sulphadiazine, phenylbutazone, betamethasone, tolbutamide, and menaphthone was studied in 2% solutions of the above surfactants, and in cetomacrogol. Excluding sulphadiazine, a linear relationship was found between moles solubilized/mole surfactant, and (log P)/molar volume of solubilizate.
