Heat stability of allyl isothiocyanate and phenyl isothiocyanate complexed with randomly methylated β-cyclodextrin

► Solubility isotherms of allyl and phenyl isothiocyanates (ITCs) inclusion complex systems were measured. ► “AP” type solubility isotherms indicate continuous increases in stoichiometry of the complexes. ► Heat stability of the spray-dried complex powders in the solid state and in paraffin was examined. ► Inclusion complexation improves the heat stability of the ITCs. ► Establishment of a compensation effect in depletion kinetics of the ITCs in paraffin.
