Titanium dioxide – is it harmful in sunscreen?

Definitely not , the German Federal Institute for Risk Assessment (BfR) also says so. Titanium dioxide is not absorbed through the skin. Furthermore, we go a step further and avoid using titanium dioxide in nanoparticle form, as these can be inhaled (e.g., in sunscreen sprays). Click here for the BfR statement.

The North Rhine-Westphalia Consumer Center also explicitly recommends using sunscreen containing titanium dioxide and zinc oxide : “If you need to use sunscreen because other protective measures, such as clothing that covers the skin, are not possible, we advise using sunscreen with natural cosmetics seals such as NATRUE or BDIH/COSMOS . These products are only permitted to contain mineral filters such as titanium dioxide (INCI name for titanium dioxide) or zinc oxide (INCI name for zinc oxide). These are chemically stable , so you can continue using the sunscreen as long as it hasn't changed smell or consistency. If you want to avoid intentionally produced nanoparticles, make sure that the word 'nano' does not appear in the ingredient list, i.e., that it only says titanium dioxide and not titanium dioxide nano.”

Why do we rely on the combination of zinc oxide and titanium dioxide?

We rely on the combination of zinc oxide and titanium dioxide because this allows us to achieve the highest level of UVA and UVB protection . Zinc oxide is more effective against UVA radiation, while titanium dioxide is more effective against UVB radiation. By combining these two substances, we can achieve a high SPF and simultaneously offer effective protection against both types of radiation. How do we know this ?
