Abstract

The invention comprises an aqueous composition comprising riboflavin in a concentration higher than that obtainable in water alone and a non-toxic, water-soluble salt of a hydroxynaphthoic acid as solubilizer and its preparation by adding the corresponding hydroxy-naphthoic acid to an aqueous solution of riboflavin. As solubilizer, any of the non-toxic water-soluble salts of the isomeric hydroxynaphthoic acids may be used but sodium 3-hydroxy-2-naphthoate is preferred. Specification 450,145, [Group VI], is referred to.ALSO:The invention comprises an aqueous composition comprising riboflavin in a concentration higher than that obtainable in water alone and a non-toxic water soluble salt of a hydroxy naphthoic acid as solubilizer, e.g. the sodium, potassium, lithium, magnesium, ammonium and organically substituted ammonium salts. There may be also incorporated therein thiamine hydrochloride, nicotinamide, dpentothenyl choline chloride inositol and water in-C, pentothenic acid, folic acid, biotin, choline chloride, inositol and water insoluble vitamins such as vitamin A, vitamin D2, vitamin D3, a -tocopherol and/or other water-insoluble ingredients with a suitable dispersing agent. Specification 450,145 is referred to.
