Guar gum is formed by the etherification reaction with non-ionic propylene oxide reagent with guar gum. Hydroxypropyl Guar Gum is used as an inert ingredient as a thickener indetergent formulations. For manufacturers of personal care products such as body lotions, shampoos, soaps, skin care and anti-aging products, eye and facial makeup, lipsticks, toothpaste, shaving creams and lubricants etc, Guar Gum are widely used.
The multiple purpose of the guar gum as a thickener and a conditioner in personal care has prompted to even more research and usage to the galactomannans. Their exhibition of a longer flowing Rheology means they make for easier application of the active ingredient to the skin, while not affecting the normal biological processes of the skin.The guar gum use in personal care products is rapidly becoming the norm.
Guar gum ether shows a pseudoplastic rheological behavior: At low shear rate values, guar and cellulose are very close to each other, while, at high shear rate values, the viscosity of a solution of guar decreases more significantly. This lower viscosity gives the wet mortar good workability and a smooth surface.Thus, guar improves the adhesion and the wet system's stability without negatively influencing neither its consistency nor its water retention and showing excellent workability and a perfect finish.
Hydroxypropyl Guar Gum has excellent water retention properties due to adequate molar substitution. Water retention is considered the most important parameter in the construction application and helps in the binder's better setting. It also reduces the effect of plastic shrinking.
Guar ether improves the consistency of the mortar. This avoids the sagging of plaster and improves the resistance to tile sagging when applied on vertical walls.
