TRIETHYLAMMONIUM DMPA/IPDI COPOLYMER.

Valuable / NAIL CONDITIONING

TRIETHYLAMMONIUM DMPA/IPDI COPOLYMER is a specialized polyurethane dispersion engineered to create a durable, thin film on the skin. This polymer functions primarily as a film-former, contributing adhesive properties to skincare and cosmetic formulations.

Summary

Film former Skin conditioning

Science

Mechanism of Action

Operating as a polyurethane dispersion (PUD), TRIETHYLAMMONIUM DMPA/IPDI COPOLYMER forms a resilient, transparent layer upon application to the skin. This layer enhances product adhesion and provides a protective, flexible barrier.

Stability

This waterborne polyurethane dispersion exhibits optimal stability within a basic pH range of 8.0 to 9.2, maintaining integrity for at least 6 months post-synthesis. It remains stable in cosmetic products at concentrations between 5% and 15% under standard environmental conditions.

Conflicts

  • High concentrations of residual isocyanate monomers, which are precursors that can cause skin and conjunctival irritation, as well as allergic reactions.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel considers polyurethanes, including similar copolymers, safe for use in cosmetics when formulated to be non-sensitizing and within appropriate concentrations. Rigorous quantification of residual isocyanate monomers is critical for safety, as these precursors have been linked to occupational asthma, irritant and allergic contact dermatitis, and ocular irritation.
