Guar Gum (Cosmetic Grade Thickener)
Guar Gum is derived from the ground endosperm of the guar plant, Cyanmopsis tetragonolobus belonging to the family Leguminosae. The guar plant is mainly grown in India and Pakistan from the month of July to December. At harvest time, the seeds are extracted from the pod of the plant and then ground into guar gum.
Guar Gum is water soluble. When adding Guar Gum to a mixture it is best to add small quantities at a time. Be sure to stir for a while after each addition. If Guar Gum is added too quickly or in large quantities, it will gel or clump together. Guar Gum works well in mixtures that freeze but not in extreme heat or in pH (above pH8 or below pH5). Do not use if your formula contains Borax or Calcium.
