- dialkyl sulfosuccinate-coated hydrotalcites are non-dialcohol additives Contain heavy metal and harmless from a toxicological point of view and are therefore preferred. This can ensure that in the further processing of polyurethane urea fibers such as. the coloring does not produce effluents, which is the functioning of a biological reduce or destroy the working sewage treatment plant.
