Analysis of the Intrinsic Viscosity Behavior in Polymer Mixtures of Stud Plant Mucilage (Dicerocaryum zanguebarium) with Carboxymethyl Cellulose and Guar Gum: Synergism at Infinite Dilution

Shadreck Muyambo

Abstract


Compatibility studies of the stud plant mucilage (SpM) with guar gum (GG) and carboxymethyl cellulose (CMC) were elucidated using the following parameters: viscous synergy ( ), interaction index ( ) and enhancement index ( . These parameters were derived from the intrinsic viscosity ( ) obtained from the binary system of SpM–CMC and SpM–GG, measured at 0.05 g/dl. The effects of salt (NaCl) on the binary systems were also investigated at 0.0 mM, 20.0 Mm and 40.0 mM.  and showed that synergism occurs at ratios of 50:50 and 25:75 for SpM:GG and 25:75 for SpM:CMC. Salts reduces  and , though the effects were more pronounced in the SpM–CMC binary system. The SpM–GG binary system showed both enhanced viscosity and salt buffering properties which might be beneficial to various manufacturing industries, including food.
