Eastman AQ™ polymers for Cosmetics and Personal Care include Eastman AQ™ 38S, 48 Ultra, and 55S. These polymers are sulfopolyesters that disperse directly in water without the assistance of surfactants or other additives. Low-viscosity aqueous dispersions can be prepared at concentrations up to 30% polymer solids. AQ polymers aid the dispersion of hydrophobic ingredients in water-based formulations and form clear films at room temperature from aqueous dispersions.

Eastman AQ™ 38S, 48 Ultra, and 55S polymers differ in glass transition temperature (Tg), alcohol tolerance, and dispersion temperature. AQ 38S and 55S are more water resistant than AQ 48.

The INCI name for Eastman AQ™ 38S, 48 Ultra, and 55S polymers is Polyester-5.
