Abstract
Mixtures of esters of chlorine-substituted phenols are employed for the protection of textile materials from attack by micro-organisms. Dichlorophene, acetic anhydride and fatty acids with 6 to 20 carbon atoms are reacted together, and the acetic acid formed and excess acetic anhydride are substantially removed by distillation. Concentrated aqueous emulsions of the resulting mixture of esters are then produced for application to textiles.
