Dear Adarsh,

guar gum is an exo-polysaccharide composed of galactose and mannose from bacterial fermentation. In water, it is nonionic and hydrocolloidal. Viscosity is dependent on temperature, concentration, pH, rate of agitation and practical size of the powdered gum used. Guar gum (like other rheology modifiers) has a strong tendency to form lumps when added to the water. To reduce this risk it may be dispersed into non-aqueous phase liquids such as oils, alcohols or glycols. This “slurry” is then added to the aqueous phase allowing the gum to hydrate with a reduced risk of lump formation. Where separate or concentrated gum solutions are prepared dispersion aids are obviously not an option. The powder has to be added to the liquid under vigorous agitation at a controlled rate to reduce the formation of agglomerates. The guar powder must also be added rapidly because addition of powder becomes increasingly difficult as the viscosity increases. However, these difficulties may be overcome when using an Ultra Turrax high speed disperser that can produce an agglomerate-free dispersion and fully hydrate Guar gum in a fraction of the time taken by conventional methods. A detailed protocol which you can easily adjust to your requirements as regards the amount of guar gum solution to be prepared can be found here:
