Product Details

Guar gum CAS#9000-30-0

White to light yellowish.Free flowing powder.Close to odorless.Form viscous liquid after dispersing in hot or cold water. The viscosity of 1% aqueous solution is about 4~5Pa which is the highest viscosity in natural rubber. After adding small amount of sodium tetraborate it changes to gel.
After dispersing in cold water for about 2h it shows strong viscosity and the viscosity gradually increases reached the highest point after 24h.Its viscosity is 5 to 8 times than that of starch and quickly reaches the highest point under heat.The aqueous solution is neutral.The viscosity is highest with pH between 6 and 8 and substantially decreases when pH is above10. And viscosity decreases sharply along with pH value dropping when pH value is 6.0 to 3.5. The viscosity below 3.5 increases again.

Product Application of Guar gum CAS#9000-30-0

Guar gum is obtained from the seed kernel of the plant cyamopsis tetragonoloba. It has a mannose:galactose ratio of approximately 2:1. It is dispersible in cold water to form viscous sols which upon heating will develop additional viscosity. A 1% solution has a viscosity range of 2,000–3,500 cp at 25°c. It is a versatile thickener and stabilizer used in ice cream, baked goods, sauces, and beverages at use levels ranging from 0.1 to 1.0%. It is scientifically termed guaran.
