乳化剂和共乳化剂对甲维盐水乳剂乳液稳定性的影响
Effects of emulsifier and co-emulsifier on the particle diameter and surface tension of emulsion in water of emamectin benzoate
摘要
Abstract
Based on the successful screening for the optimal emulsifiers and co-emulsifiers, the effects of hydrophile lipophile balance (HLB) values of emulsifiers and the concentrations of emulsifiers and co-emulsifiers on the stability of 1％ emulsion in water (EW) of emamectin benzoate were studied at 54 ℃ for two weeks. In addition, the stability of emulsifiers was studied. The results showed that the stability of the latex was related to the HLB values of the emulsifiers. The particle diameter and surface tension of the EW decreased corresponding to the increase of the concentration of emulsifier, but particle diameter and surface tension of the 1％ emamectin benzoate EW tended to be stable whether the concentration of the emulsifiers increased or not at a higher concentra tion. No significant effect of co-emulsifiers on the particle diameter of the EW was found. However, co-emulsifiers could increase the stability of the 1％ emamectin benzoate EW by decreasing surface tension. The results indicated that the stability of the 1％ emamectin benzoate Ew could be reflected by particle diameter and surface tension of the latex. The concentration and classes of emulsifier and co-emulsifier with the lowest HLB values were thought to be the optimal, if the concentration and classes of emulsifier and co-emulsifier were stable after the 1％ emamectin benzoate EW was stored at 54 ℃ for two weeks.关键词
