This invention relates to useful materials and mixtures thereof for use in wetting agents,

detergents and/or cleaning products and, more particularly, to a new form of preparation

of this known class of materials where they are present as pourable and/or free-flowing granules. More particularly, the teaching according to the invention seeks to provide

products of the type in question which are distinguished by a combination of important

performance parameters for the particular field of application in question which has been

difficult to achieve in the hitherto conventional production of the useful materials in question

on an industrial scale.
