Titanium dioxide (TiO2) is a pure white pigment that occurs naturally as a crystal.
Titanium dioxide acts as a physical sunscreen.
It can be listed as CI 77891, titanium white, or pigment white 6. When used as a food colouring it has E number E171.
Titanium dioxide has a wide range of uses. It is used as a coloring in both food and cosmetics, and adds definition to bubbles in soap lather.
It helps to increase the opacity of a product. We use it in our delicious Porridge soap, which helps give it that rich and creamy appearance.
When used in our Comforter Bubble Bar, it embraces you in brilliantly white bubbles for a luxurious and comforting bath.
Titanium dioxide has a high refractive index of n=2.7.
It has strong UV absorption capabilities. It remains stable and does not discolor when exposed to ultraviolet light. This enhances its ability to protect the skin from the effects of ultraviolet light.
Sun creams designed for infants, or people with sensitive skin, are often based on titanium dioxide (and zinc); these mineral UV blockers are less likely to cause skin irritation than chemical UV absorbers.
