摘要

A concentrate formulation, which can be diluted homogeneously with water, comprising an essential oil microencapsulated in an aqueous liposome system, comprises (by weight) 0.01-20.00 % hydrogenated lecithin, (0.10-50.00 % essential oils, and 35.00-99.00% water, is new. An Independent claim is also included for the preparation of (I), by preparing an empty liposome system above the phase transition temperature then charging with the essential oils.
