The present invention relates to a carrier for administering biologically active compounds comprising one or more C 1 -C 4 alcohols, polyols or polymers thereof, water and one or more di- and/or mono-(electron transfer agent) phosphate derivatives, wherein the phosphate derivative is an acid form of the phosphorylated electron transfer agent, a salt of the phosphate or a derivative in which the phosphate proton is replaced by a C 1 -C 4 alkyl group or phosphatidyl group or a phosphate ester of electron transfer agents in which the phosphate is ortho-phosphate or pyrophosphate di- or monosubstituted with electron transfer agents, and wherein the electron transfer agent is tocopherol or tocotrienol.
