In this study, we found that organogels composed of mixed alkylhydrazide derivatives with different alkyl chains as low-molecular-weight organogelators showed thixotropic properties, whereas organogels composed of a single alkylhydrazide component did not show such properties. With a two- or three-component system of alkylhydrazides, the transparency and mechanical properties of the resulting organogels were enhanced. This mixing enhancement for organogelators might be due to an improved network of closer and finer fibers compared to that in a one-component system.

Mixtures of alkylamide derivatives with different alkyl chains were found to form organogels which exhibit thixotropic properties, while single alkylamide components formed organogels which did not exhibit such properties. With a three-component alkylamide system, the transparency and mechanical properties (toughness and stimulus-responsiveness) of the resulting organogels were enhanced. This mixing enhancement for organogelators may be due to the improved network density compared with that of the one-component systems.

Multicomponent alkylamide organogels containing non-volatile oils were generated as potential thixotropic host materials for medicinal applications such as ointments.

Hydrogels made from new gelators exhibit thixotropic properties, whereas hydrogels formed with structurally similar N-alkyl-d-glucamide have a tendency to crystallize.
