How is Titanium Dioxide Used in Soap?
In soap, titanium dioxide is added to give it a bright white color. It is often used in combination with other colorants to create a variety of colors. Titanium dioxide is also used as a thickening agent in some soap formulations, as it can help to increase the viscosity of the soap.

If you prefer to avoid products that contain titanium dioxide, there are alternative ingredients that can be used to achieve a white color in soap. Kaolin clay, zinc oxide, and mica powders are all commonly used as natural whitening agents in soap.
How to Incorporate Titanium Dioxide into Soap Making
To incorporate titanium dioxide into your soap recipe, it is best to add it to your oils before mixing in your lye solution. This will help to ensure that the titanium dioxide is evenly distributed throughout the soap. Be sure to use a high-quality, food-grade titanium dioxide powder for best results.
