ABSTRACT:
A sulfonated dicarboxylic acid is disclosed as a cosurfactant for its efficacy in lowering foam in alum-containing aqueous dispersed rosin size, and particularly in calcium-containing dispersed rosin size systems. The sulfonated dicarboxylic acid additive also enhances alum sensitivity of the dispersed rosin size. The addition of dioctyl sodium sulfosuccinate, DSS, cosurfactant to a salt of sulfuric acid half ester surfactant-containing dispersed rosin size lowers the tendency for foaming and increases the sensitivity of the size to alum with an attendant increase in sizing efficiency.
