Triethoxycaprylylsilane
A coating for mineral sunscreen particles and pigments — keeps them spreading smoothly instead of clumping.
What it does
It coats mineral particles such as titanium dioxide, zinc oxide and iron oxides so they repel water. That helps them spread smoothly, stop clumping and last longer on skin. It doesn’t act on skin itself.
The evidence, graded
expert consensusUS safety reviewers (2017) assessed four alkoxyl alkyl silanes. Triethoxycaprylylsilane and trimethoxycaprylylsilane coat particles and help powders such as titanium dioxide spread evenly. They judged all four safe as used, and asked makers to keep heavy metals and other impurities low.Becker 2017 · Cosmetic Ingredient Review ↗
