ABSTRACT:
Novel urea-ethoxamer inclusion compounds and a method for their production is disclosed. The new method includes mixing of the ethoxamer with a urea-organic solvent slurry and the subsequent addition of small amounts of silica substances before final curing of the mixture. Ethoxamer content of the new inclusion compounds can be as high as about 65 percent by weight. The new compounds are in the form of free flowing powders and are suitable for post addition to spray dried detergent formulations in order to substantially increase the nonionic surfactant content of the particulate detergent product.
