PURPOSE:To provide the subject dispersion not only having excellent long-time physical stability but also reduced in lowering of the potency of an electrolyte by compounding a specific surfactant. CONSTITUTION:A lecithin dispersion contains as essential components (A) an electrolyte such as the phosphate or sulfate of ascorbic acid, pyriodoxine and/or pyridoxal or the phosphate salt thereof, or tocopherol phosphate salt, (B) a phospholipid and/or hydrogenated phospholipid (preferably having an iodine value of 0-60) and (C) a polyoxyethylene alkyl ether, preferably one having a polyoxyethylene with chain length of >=10 moles, the alkyl chain being cholesterol, phytosterol or a hydrogenated product thereof. The component C is compounded in an amount of 3-30% based on the component B. The dispersion is preferably prepared with a strong emulsifying machine such as an ultrasonic emulsifying machine or microfluidizer, thereby readily providing the dispersion having fine particle diameters. |
