Eastman supplies the sun care segment of the cosmetic industry with Eastman AQ™ 38S polymer, a water-dispersible film former that has the capability to greatly improve water resistance in a variety of sunscreen sprays, lotions and creams for the care and protection of the skin.

Eastman AQ™ 38S polymer is found to be valuable in increasing the duration of UV protection in sunscreen formulas. For example, Eastman AQ™ 38S offers superior water resistance, providing retention of UV absorbers on the skin even during water exposure. It is characterized by ultrafine dispersions, is an excellent film former, is perfect for use in water-resistant sunscreens, requires no neutralization, goes into the water phase, and aids the emulsification of oil-phase UV absorbers and other organic emollients usually present in sunscreen emulsions.
