Eastman AQ ™48 Ultra polymer is a sulfopolyester that disperses directly in a mixture of ethanol and water at room temperature or in warm water without the assistance of surfactants or other additives. Low-viscosity aqueous dispersions can be prepared at concentrations up to 30% polymer solids. The aqueous or hydroalcoholic dispersions have water-like viscosity at concentrations up to about 20% polymer. AQ polymers aid the dispersion of hydrophobic ingredients in water-based formulations and films formed from the dispersions are clear and glossy at room temperature. Eastman AQ™ 48 Ultra polymer was designed specifically for use as a hair fixative in 55% VOC hairspray. Therefore, it is more compatible with higher levels of alcohol than Eastman AQ ™38S or 55S, and has good wash out with shampooing. AQ 48 polymer provides excellent hold at high humidity in aerosol and pump hairsprays, as well as in clear styling gels. Eastman AQ™ 48 has a Tg (glass transition temperature) of about 48°C. AQ 48 polymer is supplied as pellets.
