Science
Mechanism of Action
It functions as an opacifying agent to diminish translucency and as a bulking agent to adjust cosmetic density. While it can act as an abrasive, this use is not recommended for skin due to micro-tear risk. It also possesses adsorbent properties and may inhibit makeup transfer.

The Formula
Formulation
Stability
Generally poorly soluble in water (0.02 g/100 mL), with a dihydrate slurry pH of 7.0-8.0. It is more soluble in acidic conditions but stable in alkaline solutions; monohydrate forms can be stabilized by organic compounds.
Conflicts
- Should be formulated to be nonirritating, particularly avoiding abrasive applications due to potential for micro-tears.
- Requires careful formulation to ensure no negative chemical or physical interactions with other ingredients.
Safety
Safety Profile
The CIR Expert Panel confirmed its safety in cosmetic concentrations when formulated to be nonirritating. The FDA also lists it as generally recognized as safe (GRAS).
