Isopropyl Titanium Triisostearate

Isopropyl Titanium Triisostearate

A coating for mineral pigments and UV particles — makes them water-repellent so they spread evenly and wear better.

What it does

It coats pigments and mineral sunscreen particles like titanium dioxide and zinc oxide so they repel water, spread evenly and wear better. It’s there for texture and wear, not to change your skin.

The evidence, graded

expert consensusUS safety reviewers (2025) say isopropyl titanium triisostearate is used only to coat pigments, such as iron oxide, to which it is bound. It’s used at up to 1.4%, in eye shadows. They judged it safe as used in that role. If products turned out to hold much of it unbound, they said more safety tests would be needed.Johnson 2025 · International Journal of Toxicology ↗
