Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) identified Polyurethane-44 in a 2017 draft report on polyurethanes. While the report highlighted concerns regarding residual diisocyanate monomers (associated with occupational asthma and various skin irritations), the CIR Panel found 17 related HDI polymers (which include Polyurethane-44) to be safe under current cosmetic use practices and concentrations. However, a specific maximum concentration for Polyurethane-44 itself has not been established, resulting in an 'insufficient data' status for this particular ingredient.

Verdict

Insufficient Data

Polyurethane-44's role as a formulation aid is noted, but the CIR's 'insufficient data' status for this specific ingredient necessitates further safety evaluation for its use in precision skincare.
