A stable water soluble composition containing lysophosphatidylethanolamine(LPE) or lecithin is provided to prevent precipitation of lysophosphatidylethanolamine at room temperature below 20 deg. C, and maintain the transparent formulation of the composition during the long-term storage. The stable water soluble composition contains 0.1-50 wt.% of any one of lysophosphatidylethanolamine(LPE) and lecithin containing 3% or more of lysophosphatidylethanolamine(LPE), 0.1-60 wt.% of fatty acid or its salt and 10-99.8 wt.% of solvent; the fatty acid has the carbon number of 3 to 22; the salt of fatty acid is sodium salt, potassium salt, ammonium salt or ethanolamine salt; the solvent is a mixed solvent of water and alcohol; and the alcohol is ethanol, isopropanol, butanol, hexanol and oleyl alcohol.
