Improved rosin ester compositions are provided having diminished tendency toward hazing concomitant with good viscosity stability when employed in adhesive systems such as hot melt adhesive systems. Addition of zinc composition to rosin ester formulations in an effective amount serves to secure these improvements. Zinc oxide, zinc hydroxide and zinc salts of organic acids are suitable for employment with zinc resinates being preferred in accordance with the practice of certain embodiments.
