Science
Mechanism of Action
XDI contains two isocyanate functional groups that readily react with nucleophilic components in skin proteins and other biological molecules. This high reactivity directly causes its classification as a skin irritant and sensitizer, making it entirely unsuitable for dermal application.

Dusting Analysis
Xylene Diisocyanate is an industrial chemical and is not utilized in cosmetic formulations, thus it is not subject to 'dusting' concerns typical of cosmetic powders.
The Formula
Formulation
Stability
Xylene Diisocyanate is highly sensitive to moisture, air, and heat, undergoing hydrolysis in the presence of water to form urea derivatives. Isocyanate hydrolysis is pH-dependent, with diamine formation favored under both basic and acidic conditions.
Conflicts
- moisture
- water
- strong oxidizing agents
- compounds with active hydrogen (e.g., alcohols, amines)
Safety
Safety Profile
Xylene Diisocyanate has not been specifically reviewed by the CIR Expert Panel as a cosmetic ingredient, though related polymers have been noted for irritation potential. It is classified as a substance capable of causing allergic skin reactions, serious eye damage, and organ damage upon exposure.
