Stability
As a polyurethane, this ingredient is generally stable under normal conditions, typically resisting hydrolysis within a pH range of 4-9.
Safety
Safety Profile
While this specific ingredient lacks a direct CIR review, similar bis-HEMA copolymers have larger molecular sizes, which inherently reduces skin penetration and lowers potential for irritation. Related ingredients are rated low for allergies and categorized as 'Irritant Free' by third-party assessments.
