Abstract
Aqueous solutions of xanthan gum hydrophilic colloid, that would otherwise support microbial growth, are preserved with chromic acid. The solutions should be at a pH above 3, and contain minimal amounts of reduced forms of chromium, if any, so that they will be storage stable not only against microbial growth, but also against gel formation.
