New phosphorus-containing emulsifierThe Soviet Union successfully developed two new phosphorus-containing emulsifiers - stearic acid phosphate and oleic acid phosphate, which have been used in cosmetics production and have achieved good results. The preparation method is to first use acidic phospholipids and caustic potassium alkali aqueous solution to neutralize, and then use the obtained phosphoric anhydride to phosphorylate high-fat polyethylene glycol ester. It should be noted during the reaction that the most appropriate amount of phosphoric anhydride must be selected. Phosphoric anhydride is added in two parts. When the first part of phosphoric anhydride is added, the polyethylene glycol-400 contained in the raw material reacts with it; and when the second part of phosphoric anhydride is added, the monostearate or monooleate Пэ--400 undergoes a phosphorylation reaction. For the phosphorylation reaction of stearate, if the same amount of phosphoric anhydride is added each time, …
