<p>An aqueous gel pig has a shear viscosity of at least 45000 or a "10/100 20/40" settling rate result at 60 minutes of no more than 8 millimetres. The gel is formed from a composition of an anionic or cationic polymer, a lesser amount of a counterionic surfactant, a hydrophobic alcohol, an amphoteric surfactant and amine oxide, where the gel has a Zeta potential of 20 millivolts or higher or -20 millivolts or lower.</p> |
