Abstract

The interaction of six nonionic surfactants α-[4-(1,1,3,3-tetra-methylbutyl)phenyl]-ω-hydroxypoly(oxy-1,2-ethanediyl) with hydroxypropyl-β-cyclodextrin (HP βCD) and dimethyl-β-cyclodextrin (DIMEB) was studied by reversed-phase thin-layer chromatography in the presence and absence of sodium chloride. Each surfactant formed complexes with both cyclodextrin derivatives; however, the strength of interaction varied considerably. DIMEB formed more stable inclusion complexes with the surfactants than did HP βCD. A longer ethyleneoxide chain decreased the strength of interaction, whereas sodium chloride exerted a negligible impact. Principal component analysis indicated that both the hydrophobicity and the specific hydrophobic surface are of the surfactant influenced the complex formation indicating the hydrophobic character of the interaction.
