Isopropyl Titanium Triisostearate

This ingredient is an synthetic emollient, emulsifier, and used as a surface treatment for pigment particles (like iron oxides or titanium dioxide).

The “triisostearate” part of this ingredient is an ester derived from isostearic acid, a long-chain fatty acid.

It "wraps" these ingredients in a form of slippery jacket so they disperse more evenly in oils, glide better on skin, and stick longer without smudging.

Human repeat insult patch tests on foundations containing this ingredient found no sensitization concerns.

Since isostearic acid is a C18 fatty acid, it falls within the carbon chain length that Malassezia can potentially metabolize. This is why this ingredient may not be fungal acne safe.
