文摘

Interfacial properties of dodecyl-β-d-maltoside (DDM) and dodecyl-β-d-fructofuranosyl-α-d-glucopyranoside (DFG) are being explored at both the air/water and dodecane/water interfaces. While surface tensiometry was employed for the study of the air/water interface, the dynamic drop volume technique was used to explore the oil/water (o/w) interface. Both surfactants are water soluble and non-ionic in nature. These surfactants differ slightly in their head group composition, whereas the structure of their alkyl tail is identical with same number of CH₂ groups in it. Therefore they differ slightly in head group polarity, and therewith in HLB (hydrophilic–lipophillic balance) value.
