EASTMAN AQ™ 38S POLYMER forms flexible films on the skin. It imparts a smooth feel to creams, lotions, and sprays and adheres to the skin. Thus, it is useful as a film-former in sunscreen products, providing excellent water resistance. AQ 38 is added to the water phase and aids the emulsification of oil-phase UV absorbers. AQ 38 provides improved coverage for sprayable sunscreens.

EASTMAN AQ™ 55S POLYMER is a sulfopolyester that disperses directly in hot water without the assistance of surfactants or other additives. AQ 55S polymer aids the dispersion of many hydrophobic ingredients in water-based products and forms clear films at room temperature from aqueous dispersions. Eastman AQ ™55S has good film integrity when combined with other cosmetic ingredients and is the preferred AQ polymer to improve water and smudge resistance of water-based makeup and mascaras. In hairstyling products, AQ 55S provides excellent hold under high-humidity conditions and stiffness that is easily modified with plasticizers and thickeners. The "S" indicates AQ 55S is supplied as solid pellets.
