The present invention relates to the preparation of powder or solid compositions comprising single and double chain amphiphilic lipids in association with polymers which harden them so that they can be comminuted into powder or granules. The compositions can act as carriers for biologically active compounds and can be administered to living organisms. Such a composition may comprise a biologically active compound and monoacyl and diacyl membrane lipid in association with a polymer, said composition being a solid that when stored in a glass container remains free flowing after 3 months at 40 °C and 75 % relative humidity. The lipids may be selected from those which have GRAS status e.g. enzyme modified lecithin, and the polymer may be selected from natural polysaccharide polymers, starches and their derivatives, cellulose and its derivatives and gelatines. |
