Pigments and oxides are one of the most popular colorant options for cold process soap. They are non-bleeding and don’t morph in the high pH environment of freshly poured soap. Oxides come in a wide variety of hues, and are easy to mix to create unique colors. One of the most popular colorants is titanium dioxide, which gives soap a white color. It’s commonly used to transform soap from cream to white, or to lighten other colors.
A natural white opaque pigment, titanium dioxide is used in a wide variety of applications including paints, cosmetic products and food. The mineral is processed to remove impurities, resulting in a pure white color. The titanium dioxide found at Bramble Berry is both oil and water soluble, making it a great option for cold process soap. Titanium dioxide is commonly used in commercial sunscreen products because of its ability to absorb UV light.
