Influence of pH and Ultrasonic Treatment on Preparation of Titanium Phosphates and Their Powder Properties


Titanium oxide that has the photocatalytic activity is used as the white pigment for cosmetics. A certain degree of sebum on the skin is decomposed by the ultraviolet radiation in sunlight. In this work, as a novel white pigment, titanium phosphates were prepared from titanium sulfate and phosphoric acid at pH 5, 7, and 9, with/without ultrasonic treatment for cosmetics. Their chemical composition, powder properties, photocatalytic activity, color phase, moisture retention, and smoothness were studied. These titanium phosphates had less photocatalytic activity to protect the sebum on the skin. Sample prepared at pH 7 without ultrasonic treatment had higher moisture retention than other samples. All samples obtained in this work had the suitable smoothness for cosmetics.
