Does titanium dioxide cause cancer?

Titanium dioxide is a common inorganic compound, which is widely used in cosmetics, food, medicine and coatings. According to current scientific research, titanium dioxide itself is not carcinogenic.

However, it should be noted that if titanium dioxide is added to some products, and these products are used improperly or in excess, it may have a negative impact on human health. For example, some studies have shown that long-term exposure to sunscreens containing high concentrations of titanium dioxide may increase the risk of skin cancer. In addition, some people may be allergic to titanium dioxide, resulting in skin itching, redness and other discomfort symptoms.

Therefore, when using products containing titanium dioxide, attention should be paid to the method and dosage of use to avoid overuse or improper use. At the same time, if any symptoms of discomfort occur, the use should be stopped and the doctor's advice should be consulted.

Which foods contain titanium dioxide?

Titanium dioxide is a food additive, also known as white pigment, which is the abbreviation of food-grade titanium dioxide. It is a non-coated anatase titanium dioxide with high separation, also known as food grade titanium dioxide, or pharmaceutical grade titanium dioxide, used as colorant and food whitening agent, non-toxic, tasteless, white powder, sometimes in order to facilitate dispersion, also made into liquid, widely used in pharmaceutical, food, cosmetics and other industries.

Foods containing titanium dioxide include jams, preserved fruits, dehydrated potatoes, fried nuts, chocolate products, cocoa products, candies, salad dressings, jellies, solid drinks and puffed foods.

Titanium dioxide in sunscreens and other products

Titanium dioxide is a common physical sunscreen that blocks UVB and some UVA rays by reflecting and scattering. FDA's maximum concentration of titanium dioxide in sunscreen cosmetics is 25%. In addition to being used as a sunscreen, it is also used as a colorant in a large number of makeup products such as foundation, air cushion, plain cream and so on.

Titanium dioxide in tampons and pads

Titanium dioxide in tampons and pads is a pigment used as a stain on tampon strings. The titanium dioxide used is less than 0.1% of the total composition of the tampon. Since the exposure level is very low, the associated carcinogenic risk is likely to be very low.
