The present description provides esterified fatty acid and/or tall oil compositions and their use as alternative plasticizers in adhesives formulations. These esters demonstrate similar or improved performance over adhesives industry standard plasticizers. The description also provides methods of manufacturing and using the same, for example, to improve or modify the performance of adhesive materials, such as, hot melt pressure sensitive adhesives and hygienic adhesives.
