<p>Disclosed are novel aqueous dispersions of ampholytic polymers. The dispersion pH of 2 to 6 allows the dispersion to contain high levels of the ampholytic polymer and remain pourable where similarly active solutions would be in a non-pourable gel form. The use of the novel aqueous dispersions of ampholytic polymer, in a cosmetically acceptable medium for the treatment of a keratin-containing substrate is also disclosed. The use of the novel aqueous dispersions of ampholytic polymers to thicken aqueous solutions as an additive in the manufacture of paper, as a component in drilling fluid compositions, as a component of cementing compositions and as an agent for waste water treatment is further disclosed.</p> |
