Guar Gum Powder

Guar Gum is a white to yellowish white powder. It is nearly odorless. Dissolved in hot or cold water guar gum forms a paste of high viscosity. Guar’s viscosity is a function of temperature, time and concentration.

  • It is soluble in hot and cold water but insoluble in most organic solvents.
  • It is non-ionic and maintains a constant high viscosity over a broad range of pH.
  • The viscosity of its solution increases gradually with increasing concentration of guar gum in water.
  • Temperature, pH, presence of salts and other solids influence the viscosity of guar gum solution.
    Guar gum forms highly viscous colloidal dispersions when hydrated in cold water.
  • The time required for complete hydration in water and to achieve maximum viscosity depend on various factors, i.e., the pH, temperature, grade of powder used and equipment etc.
  • Guar gum is compatible with a variety of inorganic and organic substances including certain dyes and various constituents of food.
  • Guar gum has excellent thickening, emulsifying, stabilizing and film forming properties
  • At very low concentration, guar gum has excellent settling (flocculation) properties and it acts as a filter aid.
    Guar gum powder has strong hydrogen bonding properties.
