Titanium Dioxide: Carcinogenic or Safe?

In recent years, titanium dioxide (TiO2) has been a topic of controversy in the food and cosmetics industries. As an additive alimentare, it’s used in various products such as candies, sauces, fish-based foods, and dairy products. But is TiO2 safe for human consumption? Or does it pose a risk to our health?

What is Titanium Dioxide?

Titanium dioxide is a white powder compound used in both the food industry and cosmetics. It’s often used as an additive alimentare with the E number E171. In addition, it’s also known as diosside of titanium or simply titanium oxide.

In the food industry, TiO2 is used to give products their characteristic whiteness and to improve their color. For example, it’s commonly used in:

  • Candies
  • Sauces
  • Fish-based foods
  • Dairy products

Cosmetic Applications

In the cosmetic industry, TiO2 is used as a pigmenting agent to give creams and other products their white color. It’s also believed to have absorbent properties.

Some common cosmetic products that contain TiO2 include:

  • Face powders
  • Toothpaste
  • Sunscreens
  • Lip balms

Cancerogen or Safe?

In 2018, the French National Institute for Agricultural Research (INRA) published a study claiming that consuming TiO2 could lead to an increased risk of colon-rectal cancer and immune system dysfunction. This finding raised concerns about the safety of TiO2 as an additive alimentare.

However, the European Food Safety Authority (EFSA), which is responsible for assessing the safety of food additives in Europe, has not found conclusive evidence that TiO2 is a carcinogen. In fact, the EFSA has classified TiO2 as “safe” for human consumption.

The Debate Continues

While some studies have suggested that TiO2 may be linked to cancer and other health problems, more research is needed to confirm these findings. The current evidence base on the safety of TiO2 is limited, and further studies are required to fully understand its effects on human health.

One of the main concerns with TiO2 is its potential toxicity. Some studies have suggested that TiO2 can cause oxidative stress and inflammation in the body, which could lead to a range of health problems. However, more research is needed to confirm these findings.

What’s in the Labeling?

In food products, TiO2 is labeled as E171 on the ingredient list. In cosmetics, it’s often listed as CI 77891 or titanium dioxide.

To ensure that you’re not consuming or using products containing TiO2, it’s a good idea to check the ingredient label carefully. Some companies may use alternative pigments or colorants instead of TiO2, which could be considered safer for human consumption.

Conclusion

The question remains: does titanium dioxide pose a risk to our health? While some studies have raised concerns about its safety, more research is needed to confirm these findings. For now, the EFSA has deemed TiO2 “safe” for human consumption. However, if you’re concerned about your health, it’s always best to err on the side of caution and avoid products containing TiO2 whenever possible.
