POLYURETHANE-82.

Valuable / FILM FORMING

POLYURETHANE-82 is a polymeric compound valued for its mechanical flexibility and biocompatibility. In precision skincare, it primarily functions as a film-former, creating a protective barrier that helps maintain a moist environment essential for optimal skin health and potentially supporting cellular regeneration.

Summary

Film-forming Skin-conditioning Moisture Retention

Science

Mechanism of Action

As a polyurethane polymer, POLYURETHANE-82 contributes to skin integrity by forming a flexible, non-occlusive film that helps to minimize transepidermal water loss, thereby maintaining optimal hydration. Beyond this crucial barrier function, the broader class of modified polyurethanes has demonstrated a capacity to modulate inflammatory responses and promote tissue healing, suggesting a role in advanced skin recovery and conditioning.

Stability

POLYURETHANE-82 exhibits low water solubility. Polyurethanes generally demonstrate significant hydrolytic stability within a broad pH range of 4.0 to 9.0. However, the precise stability characteristics can vary based on the polymer's specific chemical composition (e.g., polyester- or polyether-based), which may influence its degradation profile and impact the surrounding formulation's pH.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has assessed 66 polyurethane ingredients, concluding their safety under current practices of use and concentration, provided they are formulated to be non-sensitizing. The Panel confirmed no detectable residual isocyanates or other monomers. Formulators should be aware that polyurethane raw materials may be supplied in emulsions or solutions containing potential sensitizers, such as methylisothiazolinone (MI), and should avoid their accumulation to significant concentrations.
