Explore the recorded roles of TITANIUM DIOXIDE and what they can mean in a cosmetic formula.
Source-function explanation
The panels below interpret this ingredient’s recorded functions. They describe possible contributions, not proven clinical results. Any individually reviewed study is shown separately.
01 / COSMETIC CONTEXT
For skin
Uv FilterFilters particular UV wavelengths in an appropriately formulated and authorised product. Only finished-product tests establish SPF or UVA protection.
02 / COSMETIC CONTEXT
For hair
No hair-specific function has been mapped from this source record. Hair or scalp benefits have not yet been reviewed here.
03 / FORMULATION ROLE
In cosmetics
Uv FilterUsed to filter particular ultraviolet wavelengths. Ingredient presence does not establish a product’s SPF, UVA protection or water resistance.
ColorantAdds or changes colour. Permitted applications and restrictions depend on jurisdiction and product type.
OpacifyingHelps make a formula less transparent or gives it a more opaque appearance.

Uv AbsorberHelps absorb ultraviolet radiation, which may protect the formula. This function is distinct from a finished product’s tested sun protection.

Read the benefit with the formula.
Ingredient form, concentration, pH, delivery system and contact time can change the result. A skin finding does not establish a hair benefit; a conditioning or fibre result does not establish hair growth.
Titanium Dioxide is the inorganic oxide.
To identify the colourant meeting the requirements for labelling purposes in the EU, the INCI Name 77891 must be used.
It conforms generally to the formula:

03 / INSIDE THE FORMULA
What does it do?
Colorant
Adds or changes colour. Permitted applications and restrictions depend on jurisdiction and product type.
Opacifying
Helps make a formula less transparent or gives it a more opaque appearance.
Uv Absorber
Helps absorb ultraviolet radiation, which may protect the formula. This function is distinct from a finished product’s tested sun protection.
Uv Filter
Used to filter particular ultraviolet wavelengths. Ingredient presence does not establish a product’s SPF, UVA protection or water resistance.
Functions describe possible roles in a formulation. They do not establish the performance of every product containing this ingredient.
04 / READ THE LABEL
A little more understanding.
Titanium dioxide and a colour-index label such as CI 77891 may require identity mapping. Particle form and coatings need separate documentation.
A colourant role and a UV-filter role answer different questions. The name alone does not establish finished-product sun protection.
05 / EVIDENCE & REGULATORY CONTEXT
Keep the context in view.
European Union source references
