Abstract
A resin composition is prepared by reacting components comprising dibasic acid, diamine, polyol and monoalcohol, wherein (a) at least 50 equivalent percent of the dibasic acid comprises polymerized fatty acid; (b) at least 50 equivalent percent of the diamine comprises ethylene diamine; (c) 10-60 equivalent percent of the total of the hydroxyl and amine equilvalents provided by diamine, polyol and monoalcohol are provided by monoalcohol; and (d) no more than 50 equivalent percent of the total of the hydroxyl and amine equivalents provided by diamine, polyol and monoalcohol are provided by polyol. This resin composition may be formulated into, for example, personal care products, fragrance releasing products and candles.
