Eastman AQ™ 38S Polymer

Eastman AQ ™ 38S polymer is a sulfopolyester that disperses directly in hot water without the assistance of amines, cosolvents, surfactants or other additives. AQ 38S polymer aids the dispersion of many hydrophobic ingredients in water-based products and forms clear films at room temperature from aqueous dispersions. Eastman AQ ™polymers differ chiefly in glass transition temperature (Tg) or softening point. As indicated by the number in the product name, Eastman AQ 38S polymer has a Tg of about 38°C. The "S" indicates AQ 38S is supplied as solid pellets. Eastman AQ linear polyesters serve as film formers in numerous cosmetic and personal care applications. Because of its low Tg, Eastman AQ™ 38S 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.
