Abstract
The present invention relates to a concentrated aqueous composition of metal aldonate and/or ammonium aldonate. Part of the aldonate is dissolved and part of it is suspended in the water. Sodium gluconate is preferred. The present composition should contain a colloidally dispersed gum as suspending agent. Gums containing carboxyl groups such as xanthan gum are particularly well suited for making the suspension. In this manner, stable compositions having a high aldonate content are obtained. The composition can be used in cleansing preparations for glass and metal surfaces, in solution for etching aluminum, in galvanizing processes, in the tanning of leather, in paper making, in treatment of textiles, in paint removers, fixing baths in photography, and in agricultural and pharmaceutical preparations.
