Description

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 quic

Appearance：

Yellow-white; Free Flowing Powder

Water Solubility：

soluble in cold water

Storage Conditions：

Aqueous guar gum dispersions have a buffering action and arestable at pH 4.0–10.5. However, prolonged heating reduces theviscosity of dispersions.
The bacteriological stability of guar gum dispersions may beimproved by the addition of a mixture of 0.15% methylparabenand 0.02% propylparaben as a preservative. In food applications,benzoic acid, citric acid, sodium benzoate, or sorbic acid may beused.
Guar gum powder should be stored in a well-closed container ina cool, dry place.

Toxicity：

LD50 in male, female rats (g/kg): 7.35, 6.77 orally (Graham)

Guar gum Use and Manufacturing

Food grade: frozen food:stop ice dreg from forming and increase the frozen stability. Baking food: keep the humidity and improve the texture. Drink:improve taste and stabilize particle suspension. Salad dressing: thickener, alternative oil. Cheese and cream: improve the texture.Cooked meat food: maintain water, increase oily slippery feeling. Vegetarian food: alternative fat ingredients,keep moisture. Pet goods: increase oily slippery feeling and keep the humidity.
Industrial grade: oil well fracturing and other drilling industry. Carpets, spin printing and dyeing,leather chemical industry. Building materials, cement, paint, tiles.Paper industry, pharmaceutical industry. Shampoo, detergent, skin care products, cosmetics. Viscera. Latex paint, exterior latex paint.

guar gum has a coating action on the skin that allows for moisture retention. often used as a thickener and emulsifier in cosmetic formulations, guar gum is a polysaccharide found in the seeds of the guar plant. It is the nutrient material required by the developing plant embryo during germination. When the endosperm, once separated from the hull and embryo, is ground to a powder form, it is marketed as guar gum. 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. low calorie, soluble dietery fiber In paper sizing; as a protective colloid, stabilizer, thickening and film forming agent for cheese, salad dressings, ice cream, soups; as a binding and disintegrating agent in tablet formulations; in pharmaceutical jelly formulations; in suspensions, emulsions, lotions, creams, toothpastes; in the mining industry as a flocculant, as a filtering agent; in water treatment as a coagulant aid.
Food additives, emulsifying stabilizer, thickener and gelling agent.
