Abstract:
Gelable or gelled compositions are disclosed which comprise a liquid medium, agar, and a combination of natural gum gel-forming agents including xanthan gum and locust bean gum. The gelable dispersions are easily gelled by heating to the gel-critical temperature and subsequently cooling them below the setting temperature. In the gelled state, these compositions are useful as carriers for many types of liquids including photo-processing solutions and therapeutic solutions.
