Abstract
Procédé pour fabriquer des azurants optiques en cristaux fins, de la série bis-triazinylamino-stilbénique, sous la forme cristalline- beta . Ce procédé est caractérisé par le fait qu'on mélange le tourteau aqueux de l'azurant sous la forme cristalline- beta et/ou - alpha avec une solution aqueuse d'émulsionnant à 70 degrés -85 degrés C et qu'on le broie à cette température. Ce procédé donne un azurant incolore, plus facilement dosable, ne jaunissant pas ainsi la poudre de détergent comme le fait la forme cristalline- alpha jaune.
