C., a total molar substitution of about 2.5 to about 4.0 and having a ratio of hydroxypropyl molar substitution to hydroxyethyl molar substitution of about 1:2 to 2:1. The HEHPC thickeners as described exhibit good resistance to bacterial degradation, good color development and a haze point sufficiently high to allow normal formulation of the coating composition.
