Preparation of clove essential oil-in-cyclodextrin-in-liposomes (DCL) at laboratory and large scales.
Freeze-drying of liposomes encapsulating inclusion complex of a volatile hydrophobic compound.
DCL formulations were stable in aqueous dispersions after 1 month of storage at 4 ̊C and in lyophilized forms.
DCL formulations maintained the DPPH scavenging activity of free clove essential oil, free eugenol and their inclusion complexes.
