Fracturing Method Using Low-Viscosity Fluid with Low ...

Guar is more water-soluble than other gums, and it is also a better emulsifier, because it has more galactose branch points. Guar gum shows high low-shear viscosity, but it is strongly shear-thinning. Being non-ionic, it is not affected by ionic strength or pH but will degrade at low pH at moderate temperature (pH 3 at 50.degree. C.).

Easily wettable polycarboxylic thickeners - 3V SIGMA S.p.A.

However, these powders are rather difficult to disperse in water, and sometimes develop an undesirably high viscosity even before neutralisation. Synthesis processes in the presence of surfactants, generally non-ionic, with hydrophobic-lipophilic balance (HLB) values of between 1 and 12, have been proposed to eliminate these drawbacks.
