Mesomorphic complexes of vitamin A acid and cationic polyelectrolytes, their preparation and use. The cationic polyelectrolyte, for example PDADMAC, PM4VP, poly (ionene-6,3), polyethyleneimine or a poly-L-amino acid, is mixed with vitamin A acid to produce mesomorphic complexes. Uses of these mesomorphic complexes include the transport of vitamin A in the human body, the treatment of severe cases of acne externally, courses of skin rejuvenation, and the inhibition of malignant tumors. |
