Hard gelatin capsules contain: (a) a fat-soluble nutrient, such as a fat-soluble vitamin (A, D, E or K) or an unsaturated fatty acid glyceride; (b) a nonionic surfactant, such as a polyoxyethylated (optionally hydrogenated) castor oil, and/or a polyethylene glycol; (c) a gelatin softening agent such as glycerol, propylene glycol or, preferably, glyceryl mono-oleate; and optionally (d) water. The problems of embrittlement conventionally encountered with hard gelatin capsules containing fat-soluble nutrients are reduced or avoided. |
