What is "CI 77891" and what is its purpose?

Also known as Titanium Dioxide or TiO2, CI 77891 is a white, opaque, and insoluble mineral. It is a metallic oxide. Present in the earth's crust, this natural mineral salt has numerous properties. The question that arises is: what is CI 77891 and what is its use? Let's focus on this ingredient.

Everything you need to know about CI 77891.

The CI 77891 or titanium dioxide presents itself as a white powder. It is used in sunscreens, toothpastes, confectioneries, paint, and medications.

The CI 77891 is also present in many natural and organic skincare products due to its white color, its opacifying and coloring power, and its ability to protect against UV rays.

In terms of organic skincare, CI 77891 is only permitted in sun care products. As for conventional skincare, the use of titanium dioxide nanoparticles is allowed in all types of care products.

Ci 77891: What is its purpose?

The Ci 77891 can be used as follows:

  • White dye: It imparts color to the treatments;

  • Opacifier: It makes the formulas less transparent;

  • Preservative or UV filter: In this case, it may take the form of nanoparticles. As a UV filter, titanium dioxide is coated with aluminum oxide and stearic acid. Its use as a mineral filter (especially in sun care products) is due to its ability to absorb and disperse UV rays. It is commonly used in sunscreens because of its ability to reflect light. CI 77891 protects the skin from the harmful effects of the sun.

The use of titanium dioxide in the form of nanoparticles is permitted in organic products. However, the manufacturer is required to include the term (nano) in the INCI list. CiI 77891 is used as anopacifying agent and pigment in formulas. At Typology, this colorant is particularly present in our tinted skincare products, such as the tinted serum and the tinted under-eye concealer.

CI 77891: What are the risks?

Titanium dioxide nanoparticles may be the cause of certain respiratory allergies, bronchitis, asthma, cardiovascular disorders, rhinitis, and certain cancers. In nanoparticle form, titanium dioxide could potentially damage the lungs and the peritoneum.

The topical application of treatments containing CI 77891 poses no danger. However, the ingestion of this ingredient as an food additive and the massive inhalation of CI 77891 dust can lead to risks.
