Verdict
Raw material is corrosive and a sensitizer. In cosmetics, used only as surface treatment agent for pigments/powders where it reacts and is consumed. Residual free aminopropyl triethoxysilane must be controlled below safe thresholds. Require supplier CoA confirming residual free silane levels. UN2735, Class 8 hazardous material.
