Stock solutions of polyhydroxy fatty acid amide surfactants at high concentrations are characterized by their unfortunate tendency to thicken, or gel, on storage. Mild heating and the inclusion of carboxylates such as oxydisuccinate, citrate or tartrate-succinate maintain the viscosity of such solutions below about 2,000 centipoise, even at temperatures around 30 DEG C. |
