  • Gelling compositions having a base of galactomannans and xanthan
    Patent number: 4369125
    Abstract: In a method for obtaining aqueous gels based on galactomannan and xanthan, the xanthan employed has first been subjected to a treatment resulting in partial or total deacetylation before being introduced in the mixture in which the ratio of deacetylated xanthan to galactomannan is within the range of 15/85 to 90/10. Potential applications include the food industry, explosives or air-treatment products.
