Compatibility
Works well with:
Zinc Oxide Dimethicone Cyclopentasiloxane Iron Oxides Mica Niacinamide Glycerin Cetyl Alcohol Beeswax Caprylic/Capric Triglyceride
Use caution with:
L-Ascorbic Acid Retinol
Titanium Dioxide can catalyze photodegradation of UV-sensitive actives such as L-Ascorbic Acid and Retinol upon light exposure, reducing their efficacy; surface coating (e.g., with silica or alumina) can mitigate this. It is generally inert and physically stable across a wide range of formulation types. Dispersion in oil or water phases requires proper milling or pre-dispersed forms to avoid agglomeration.
Formulation notes
EU Cosmetics Regulation limits TiO2 as UV filter to 25% in face products; as of 2022 the EU banned TiO2 as a food additive but it remains permitted in cosmetics with certain nano restrictions. Nano-grade TiO2 must be labeled 'nano' on EU packaging. Non-nano grades provide greater opacity/whitening; nano grades offer improved UV protection with reduced whitening. Surface coatings (alumina, silica, stearic acid) are common to improve dispersibility and reduce photocatalytic activity.
