HEA/IPDI ISOCYANURATE TRIMER/PG CROSSPOLYMER.

Valuable / FILM FORMING

HEA/IPDI ISOCYANURATE TRIMER/PG CROSSPOLYMER is a specialized polymer engineered to form a resilient, continuous film on the skin's surface. This film-forming property enhances product longevity, provides a smooth finish, and offers protective attributes, making it valuable in targeted cosmetic formulations.

Summary

film-forming

Science

Mechanism of Action

This ingredient functions by creating a uniform and cohesive polymeric film upon application to the skin, hair, or nails. This molecular architecture aids in improving the adherence and wear performance of cosmetic products.

Stability

The IPDI trimer component demonstrates excellent solubility in hydrocarbon solvents. While precursor aliphatic diisocyanates are insoluble in water and react slowly at room temperature (or more rapidly with heat and mixing) to generate insoluble ureas and carbon dioxide, the polymerized form exhibits distinct stability characteristics. It is incompatible with strong acids, alcohols, glycols, phenols, and various basic materials such as sodium hydroxide, potassium hydroxide, ammonia, and amines.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated the safety of structurally similar HDI polymers, including Methoxy PEG-17/Methoxy PEG-11/HDI Isocyanurate Trimer Crosspolymer, finding them to be dermally non-irritating. While a specific 'safe as used' conclusion for HEA/IPDI ISOCYANURATE TRIMER/PG CROSSPOLYMER was not explicitly stated, the assessment of related isocyanurate trimer crosspolymers suggests a low potential for irritation when properly polymerized in cosmetic applications. It is crucial to distinguish this from monomeric diisocyanates (like IPDI), which are known sensitizers and irritants; however, the polymerized form is generally considered safer due to its significantly larger molecular weight. INCI Beauty, a non-formal rating platform, assigns a 'Medium penalty' to this ingredient, which indicates a need for careful formulation consideration.
