Titanium Dioxide is an inorganic chemical compound often used in the cosmetics industry. The substance is also used in the production of medicines. Previously, Titanium Dioxide has been used as a white colorant in food production, including being found in chewing gum, coffee creamer, candy and icing, but due to the side effects of ingesting it in such concentrations in this particular form, its use in this way was discontinued. Still, the substance is valued by manufacturers of pharmaceutical and cosmetic products. Want to learn more about Titanium Dioxide? Be sure to read on!

What is Titanium Dioxide?

In nature, Titanium Dioxide is found in many minerals. It is mined and then crushed, ground or refined, depending on its use in industry. It occurs as a water-insoluble white powder. Titanium Dioxide is a substance used in many industries, especially valued by manufacturers of medicines, dietary supplements and cosmetics. It is designated with the symbol E171.

Titanium Dioxide – properties

Titanium Dioxide is a dye described by the symbol E171, otherwise known as titanium white. Most characteristic of this substance are its brightening and whitening properties. In addition, Titanium Dioxide has properties that reflect visible light, protect against the harmful effects of UV radiation, and protect other ingredients used in the production of preparations from oxidation. Titanium Dioxide does not have an expiration date if stored properly. Proper storage in the case of this substance means keeping Titanium Dioxide in tightly sealed containers at room temperature. Foodcom S.A. offers Titanium Dioxide in packages with a capacity of 25 kilograms.

Titanium Dioxide – applications

Titanium Dioxide is used in a wide variety of products including paints and varnishes, orthodontic composites, dietary supplements and cosmetics (in suntan lotions, day creams, foundations and lip balms). Titanium Dioxide protects cosmetics from oxidation and loss of their protective properties when exposed to sunlight. It leaves no white spots and is safe for use on sensitive skin. It is also used in products that require white color or brightening as a white pigment. In selected cosmetic products it acts as a thickening agent. Its use in cosmetics allows the formulation itself to be protected from oxidation and loss of protective properties when exposed to the sun.

Titanium Dioxide is widely used in cosmetics, primarily for its whitening properties. Thanks to its photocatalytic properties, the substance can act as a filter in cosmetics used to protect against UV radiation and the sun. Titanium Dioxide can be found in cosmetics such as tanning oils and lotions, day creams, foundations, eye shadows and lip balms.

Titanium Dioxide in medicines has many technological functions. It affects the color of the preparation – it can be used as a bleaching agent, but also as a brightening agent for other pigments. In addition, the presence of Titanium Dioxide ensures the stability of drugs due to its properties that allow it to absorb visible and UV light, thus protecting the individual components of the drug from degradation. This type of protection, in turn, makes it possible to extend its shelf life and durability. At the same time, Titanium Dioxide does not affect the active substances, so it does not interfere with the expected effect of the drug.
