CI 77891

TITANIUM DIOXIDE/CI 77891 is an inorganic oxide; that is the term used by the chemical description of TITANIUM DIOXIDE in the CosIng inventory, whereas that of CI 77891 classes it as an inorganic colorant. The chemical name of the entry, Titanium Dioxide/CI 77891, combines the chemical designation and the Colour Index number. In the inventory, CI 77891 has the declared colorant function, and TITANIUM DIOXIDE the colorant, opacifying, UV absorber and UV filter functions. In general, a colorant gives color to the product or the application area, and an opacifier reduces the transparency of the formula.

The substance is included in Annex IV of Regulation (EC) No 1223/2009, the list of permitted colorants, with reference 143, and its declared color is white. The warnings field of the entry combines three indications, which read verbatim: "— Purity criteria as set out in Commission Directive 95/45/E (E 171) — Titanium dioxide in powder form containing 1 % or more of particles with aerodynamic diameter ≤ 10 μm, to be used in compliance with Annex III, No 321 (For use as a UV filter, see Annex VI, No 27)". The first refers, for the purity criteria, to a Commission directive and to code E 171; the second refers to Annex III for titanium dioxide in powder form with 1% or more of particles with an aerodynamic diameter ≤ 10 μm, and the third to Annex VI for its use as a UV filter. In the inventory, the cosmetic restriction of TITANIUM DIOXIDE and CI 77891 includes IV/143.
