Viscosity, Swelling Index and Moisture Content in Gum Karaya

The present paper deals with viscosity, swelling index and Moisture content studies on Gum Karaya. We analysed ten Gum Karaya samples stored for about two years showed high viscosity of maximum about 1835 cps and swelling index 66ml/min. Gum Karaya samples of all the three grades I, II, and III showed almost the same viscosity pattern. Since viscosity is a very important factor in determining the quality of the product. Studies were extended to various biological activities. Gum Karaya can be used as a good candidate for oral floating drug delivery. Also, because of its favorable biological properties such as non-toxicity, biocompatibility, and biodegradability, Gum Karaya is a promising candidate for the enhancement of absorption of drugs through floatation using floating drug delivery system. As a result of the physical, chemical, and biological properties, Gum Karaya can is used in different formulations for drug delivery.
