Abstract

Comparison is made of the stability of anionic and cationic emulsions in the absence and presence of fleece. The quantity of oil phase removed by fleece from anionic emulsions under various conditions has been measured. Anionic wetting agents are attractive for the formulation of emulsion dips in that the uptake of oil phase on fleece samples added successively is regular and of suitable magnitude, and is largely independent of the positive ion, chain length and concentration of the wetting agent. They suffer, however, from the serious disadvantage that the uptake of oil phase varies with time of immersion, which is likely to render difficult the control of insecticide deposits.
