Is titanium dioxide harmful to the skin?

Titanium dioxide is a compound that is often used in some skin care products, especially some ingredients in makeup and sunscreen. It is a relatively stable metal oxide with strong inertness. It has a good sun protection effect and generally does not cause harm to health. It is a relatively common additive.

What is Titanium Dioxide?

Titanium dioxide (commonly known as titanium dioxide) is a permitted food coloring and no ADI value is specified in JECFA. The basis for this conclusion reached by JECFA in 1969 was that in a large number of species studies, including studies on humans, no significant absorption or tissue accumulation of titanium dioxide was found. In the European Union, titanium dioxide (commonly known as titanium dioxide) is listed as a permitted food coloring in Annex I of EC 94/36/Regulation. The titanium dioxide produced has two crystalline structures - anatase and rutile. The 94/36/Directive stipulates that only anatase type of titanium dioxide is allowed. JECFA regulations allow both forms to be used.

Is titanium dioxide harmful to the skin?

Titanium dioxide is a stable metal oxide. Because it is highly inert and has high whiteness and hiding power, high-purity titanium dioxide with low content of harmful metal elements can be used as a food additive. For example, the titanium dioxide white pigment produced in Shanghai is specifically used as a food additive, generally used in xylitol, jelly, candy, flour, fish balls, beverages, etc.

There is no problem using titanium dioxide as a food additive. Some food factories or cosmetic factories use industrial-grade titanium dioxide as a food additive. Its harmful metals, such as arsenic, lead, mercury, antimony, etc., do not meet the standards, so this kind of use is definitely harmful.

No hazard under normal use.

Titanium metal itself is a very stable substance, and titanium dioxide is a permitted food additive used for whitening. It will not denature even if fried. And even if titanium dioxide is ingested, it is a poorly soluble substance. Basically, you will excrete as much as you eat, and it will not remain in the body. Moreover, titanium dioxide has a strong ability to absorb radiation, so it can be used to make sunscreen. Compared with other sunscreen products, titanium dioxide belongs to physical sunscreen, and its chemical composition is very stable, so it is considered to be very safe among sunscreen products.
