<p>Novel synthetic phosphatidyl quaternary ammonium, sulfonium and phosphonium hydroxide compounds are prepared which have a hydrophobic/hydrophilic balance different from the natural phosphatidylcholine, which alterations are carried out by changes in the polar group to provide different surfactant properties. The phosphatidyl compounds are useful in solubilizing cholesterol, cholesterol esters and triglycerides and are useful as emulsifying agents.</p> |
