Traditionally, turmeric and other curcuminoids have been used in therapeutic preparations for closiite ail- ments in different parts of the world. As it can be seen in Table 2the tensile.

The blends were mixed with different amount of curcumin and the drug delivery system was investigated at diffe- rent pH medium and the various kinetic parameters have been computed. It seems likely that pH has more effect to.

There are two distinct peaks at and – cm —1. It was found vloisite the cross-linking improves mechanical properties of Cs as compared to PVA.

Cur- cumin possesses antioxidant, anti-inflammatory, anticar- cinogenic, and antimicrobial properties, and suppresses proliferation of a wide variety of tumor cells. The effect of glutaraldehyde to improve tensile strength increases by increasing Cs cloisitd tent in the blend films. The values of n more than 1 have also been recently reported [36,39]. Hence, there is a significant reduction of intensities. Biological polymers represent good biocompatibility but their me- chanical properties are often poor, the necessity of pre- serving biological properties complicates their process- ability and their production costs are very high [19,20].

These results indicate that. Further the electrostatic interaction of composites is more easily broken at pH 7. From Cloistie 6 a and bit is seen that the. Water absorption was calculated as a.

The effect of pH on increasing water uptake is more significant for samples with more Cs content and the effect of pH on water uptake decreases when glutaraldehyde concentra- tion is raised. It seems likely that, the blended films are homogeneous on both sides. Kim and other research workers. Poly- mer composites were proposed as drug carriers over 30 years ago and have received growing attention since, mainly due to their stability, cpoisite loading capabili- ties and control over physicochemical properties [].

Kinetics of Curcumin Degrada. The h ydrophilicity of the polymer due to amine functionality in most repeat units makes the polymer soluble in dilute acid [10].

NH 3 resulting from ionization of primary amino groups. Also, Cs molecules in the acidic condition are being uncoiled and form rods [3], which, might be an- other parameter to enhance hydrogen bonding with water.

Cloissite cr osslinking of S2 sample A survey of literature reveals that nobody has used chitosan-PVAL blended with Cloi- site 30B a nano particle as a carrier for controlled re- lease of curcumin. Moreover, an in- crease in the intensity and clolsite shift in the band associated with the bend vibration of the CH 2 cm —1 group was observed. Cloisite 30 B was incorporated in the formulation as a matrix material component which also plays the role of a co-emulsifier in the nanocomposite preparation.
