1. A thermosetting binder composition comprising:
water; and
a water-soluble oligomeric ester of citric acid and at least one saccharide selected from the group consisting of erythritol, arabitol, xylitol, sorbitol, mannitol, iditol, maltitol, isomaltitol, lactitol, cellobitol, palatinitol, maltotritol, and hydrogenation products of hydrolyzates of starch having dextrose equivalent (DE) before the hydrogenation step in range between 25 and 99,
wherein the thermosetting binder composition has a dry matter content of between 40% and 80% by weight,
wherein the water-soluble oligomeric ester represents at least 80% by weight of the dry matter content of the thermosetting binder composition, and
wherein the thermosetting binder composition contains less than 10% by weight, with respect to its dry matter content, of free sorbitol.
