PURPOSE:To prevent reduction in quality of a transparent aqueous solution resulting from hydrolysis of phospholipid with time and to maintain long-term preservation of phospholipid stably, by blending the transparent aqueous solution containing phospholipid with a specific electrolyte and adjusting the blend into proper pH. CONSTITUTION:A transparent aqueous solution of a lower fatty alcohol containing phospholipid such as purified soybean phospholipid, etc., useful as hair tonic, skin medicine for promoting nutrition or surface active agent is blended with an inorganic and/or organic electrolyte so that phospholipid in the transparent aqueous solution is stabilized. An electrolyte having pH buffering action at pH 5.5-8.6 is used as the electrolyte and disodium hydrogenphosphate, sodium carbonate, sodium hydrogencarbonate, citric acid, sodium citrate, sodium polyacrylate, etc., may be cited as the electrolyte. The prepared phospholipid- containing aqueous solution shows transparent - semitransparent appearance, the phospholipid acts as a solubilizer and the aqueous solution is used as lotion or a gelatinous solution. |
