영문 초록

The effects of HLB value of nonionic mixed surfactants on the stability and antifoaming ability for silicon oil type emulsions were studied. To obtain a stable silicone emulsions, a higher HLB values and higher content of surfactants were preferred. To obtain a good antifoaming ability, however, a lower HLB value (more hydrophobic) and a lower content of the surfactants were preferred. It was observed, at lower HLB values(8 or 9), that the silicone oil drops were spreaded on the foam surface and effectively reduced the surface tension. And the spreading phenomena presumably acted as an antifoaming mechanism. Therefore, a higher hydrophobicity of the silicone oil emulsion resulted in a higher ability of antifoaming action.
