EPITEX™ 99 Polymer

EPITEX™ 99 Polymer was created from the best features of acrylic and silicone acrylate chemistries. It marks a new hybrid solution — leveraging organic and inorganic technology — from Dow Personal Care Solutions. This silicone-hybrid film former leads the way for next-generation sun care, skin care and color cosmetics.

Performance

In testing, the performance of EPITEX™ 99 Polymer tracks closely to the silicone-acrylate benchmark. The hybrid film former exhibits high water repellency (Figure 1), high sebum repellency (Figure 2) and high film flexibility. EPITEX™ 99 Polymer forms a continuous film for excellent wash-off and rub-off resistance (Figure 3). For greater formulation and manufacturing process flexibility, this hybrid water-based film former delivers good performance in pure film and in water-in-oil and oil-n-water formulations.
