Abstract

Transport- and storage-stable paste-form detergents based on sodium hydroxide that are easily processed and handled are obtained by thickening concentrated aqueous sodium hydroxide preparations with glycols, glycol derivatives, alkanolamines, or alkanolamine derivatives. The detergents also can contain builders and other typical detergent composition ingredients.
