Eastman AQ 38S water-dispersible polymer improves the water-resistance properties of sunscreens, according to Eastman Chemical Company. The polymer is said to deliver sunscreen protection while holding up to the challenges of surf, sand and sweat.
The water-dispersible polymer also contributes to even skin coverage in lotion and pump-spray variations. Eastman AQ 38S is added to the water phase so that emulsifier usage can be reduced. Reducing the total oil phase content in the formulation reduces the oily feel that is normally associated with sunscreens.
