Abstract
A sulfopolyester comprising repeat residue units from the reaction product dimethyl-5-sodiosulfoisophthalate, isophthalic acid, 1,4-cyclohexanedimethanol and diethylene glycol, has at least one property selected from: a) an acidity of greater than 0.030 measured as milliequivalents H/gram of sulfopolyester; b) a titanium concentration, measured as metal, of less than about 27 ppm, based on the amount of sulfopolyester; or c) an acidity of greater than 0.010 measured as milliequivalents H/gram of sulfopolyester, a pH of less than 6.0 and a concentration of a base compound of less than 0.0335 moles/kg of sulfopolyester. A method for making the water-dispersible or water-dissipative sulfopolyester of the present invention is disclosed. Aqueous dispersion having from 0.001 to about 35 weight % of the sulfopolyester of the present invention is also disclosed. The sulfopolyester is useful in making hair spray formulations suitable for pump or aerosol spray applicators.
