Xanthan gum is a high molecular weight anionic polysaccharide produced by the fermentation of a carbohydrate source with Xanthomonas campestris.
This polymer exhibits three desirable properties:
(1) high viscosity at low concentrations;
(2) pseudoplasticity; and
(3) insensitivity to a wide range of temperature, pH and electrolyte variations.
Because of its special rheological properties, xanthan gum is used in food, cosmetics, pharmaceuticals, paper, paint, textiles, adhesives and oil and gas industry. The flow characteristics of xanthan, coupled with its stability to salts and extremes of pH, gives it a technical advantage over most polymers used in drilling. The greatest potential for xanthan gum appears to lie in the enhanced oil recovery operations.
The toxicological and safety properties of xanthan gum for food and pharmaceutical applications have been extensively researched. Xanthan is non-toxic and does not inhibit growth. It is non-sensitizing and does not cause skin or eye irritation. On this basis, xanthan has been approved by the United States Food and Drug Administration (FDA) for use a food additive without any specific quantity limitations (Kennedy and Bradshaw, 1984). In 1980, the European Economic Community xanthan to the food emulsifier/stabilizer list, as item E-415. Xanthan gum has been used in a wide variety of foods for a number of important reasons, including emulsion stabilization, temperature stability, co***tibility with food ingredients, and its pseudoplastic rheological properties. Table 2 lists some current uses of xanthan gum in food and other applications.
Because of its properties in thickening aqueous solutions, as a dispersing agent, and stabilizer of emulsions and suspensions, xanthan gum is used in pharmaceutical formulations, cosmetics, and agricultural products. It is used in textile printing pastes, ceramic glazes, slurry explosive formulations, and rust removers.
