Light yellow liquid to paste; characteristic odor. Moderately sol in water.

Hydroxylated lecithin is derived from a complex mixture of acetone-insoluble phosphatides from soybean and other plant lecithins, consisting chiefly of phosphatidyl choline, phosphatidyl ethanolamine, and phosphatidyl inositol, as well as other minor phospholidpids and glycolipids mixed with varying amount of triglycerides, fatty acids, sterols, and carbohydrates. The mixture is treated with hydrogen peroxide, benzoyl peroxide, lactic acid, and sodium hydroxide, or with hydrogen peroxide, acetic acid, and sodium hydroxide, to produce a hydroxylated product having an iodine value approximately 10% lower than that of the starting material. Hydroxylated lecithin may vary in consistency from fluid to plastic, depending upon the content of free fatty acid and oil and whether it contains diluents. It is light yellow in color and has a characteristic "bleached" odor. It is partially soluble in water, but hydrates readily to form emulsions; it is more dispersible and hydrates more readily than crude lecithin.
