[en] The effect of hydrophobic chain length on surface properties of enzymatically prepared n-alkyl esters of glucuronic acid are examined. Dynamic parameters from Hua and Rosen's mathematical model and equilibrium surface tension are presented for esters with octyl, decyl, dodecyl, and tetradecyl alkyl segments. Increasing the alkyl chain length has a significant influence on the surface activity. Decyl and dodecyl glucuronate exhibit an interesting adsorption speed associated with foaming capacity. Octyl glucuronate exhibits a micellar organization as its bulk concentration is over 10.68 mM. (C) 2002 Elsevier Science (USA).
