Science
Mechanism of Action
In cosmetic applications, POLYURETHANE-88 works by creating a cohesive matrix within powdered formulations. This action stabilizes the product, preventing fragmentation and facilitating smooth, consistent application on the skin.

Dusting Analysis
POLYURETHANE-88 functions as a binding agent within cosmetic formulations, which is antithetical to dusting. Its purpose is to promote cohesion rather than existing as a loose, inhalable powder component.
The Formula
Formulation
Stability
While no specific optimal pH range is defined for POLYURETHANE-88, related polyurethanes like Polyurethane-14 demonstrate stability against significant hydrolysis within a pH range of 4-9. The ingredient is generally stable under proper storage conditions, specifically avoiding extreme temperatures. It can be dispersed in water and may dissolve in highly polar organic solvents such as dimethylformamide.
Conflicts
- Strong acids (e.g., sulfuric acid, hydrochloric acid, hydrofluoric acid)
- Certain ketones (e.g., methyl ethyl ketone, acetone)
- Nitrobenzene
- Phenol
- Tetrahydrofuran
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that polyurethanes, including POLYURETHANE-88, are safe for cosmetic use when formulated to be non-sensitizing and free from residual isocyanates or other monomers. Formulators should be vigilant to ensure that raw material solutions do not contain additional sensitizers, such as methylisothiazolinone. There is no specific SCCS or FDA cosmetic status identified for POLYURETHANE-88.
