Abstract
The invention concerns a process for the dehydration of a colloidal dispersion of liposomes in an aqueous liquid medium, this process being aimed at extending the conservation of the liposomes and to enable their efficient use at a later date. According to this process, there is prepared a mixture of a hydrophilic compound and the liposome dispersion. This mixture is then subjected to a dehydration operation leading to the formation of liposomes in the form of a stable powder which can be stored for a long period and from which a dispersion of liposomes can be reconstituted.
