Organic compounds containing at least one hydrophilic group are rendered soluble in fatty systems by the formation of a chemical complex with a carrier selected among fatty acid esters of polyhydric hydroxyalkanes having general formula (I) ##STR1## wherein R 1 is H or --CH 2 OR 5 , R 2 is H or --CH 2 OR 6 , and each of R 3 , R 4 , R 5 and R 6 is independently a saturated or unsaturated fatty acid moiety having 1-30 carbon atoms or a saturated fatty acid moiety having 1-3 carbon atoms, with the proviso that at least one of R 3 , R 4 , R 5 and R 6 is a saturated or unsaturated fatty acid moiety having 1-30 carbon atoms, R2 and at least one or, when any of R 1 and R 2 is not H, at least two of R 3 , R 4 , R 5 and R 6 is a saturated fatty acid moiety having 1-3 carbon atoms. Diacetates of common monoglycerides are especilally preferred as the carriers for forming such complexes. The complexes are applicable for the incorporation of compounds containing hydrophilic groups into e.g. pharmaceuticals, cosmetics, foodstuffs and feeds, diet supplements and natural medicines as well as technochemical compositions. |
