BIS-IPDI.

Valuable / NAIL CONDITIONING

BIS-IPDI functions as a versatile polymeric ingredient, creating continuous films on the skin, hair, or nails. It also acts as a binding agent, enhancing the cohesion of powdered cosmetic products.

Summary

Film forming Binding Skin conditioning

Science

Mechanism of Action

Primarily in its polymeric forms, BIS-IPDI forms macromolecules that create a physical barrier on surfaces. This film provides structural integrity for powdered formulations and can also offer skin conditioning benefits.

Conflicts

  • Unreacted monomeric isophorone diisocyanate (IPDI) is a strong irritant and sensitizer. BIS-IPDI must be fully polymerized to ensure no detectable residual monomers.
  • Some related copolymers may present aesthetic, stability, or irritation issues in certain formulations.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The CIR Expert Panel deemed polyurethanes, including BIS-IPDI derivatives, safe when free of detectable residual isocyanate monomers. Monomeric diisocyanates are highly reactive and can cause irritation and sensitization.
