摘要:

以聚甘油-2-二油酸酯、十聚甘油单月桂酸酯分别替代Span-80、Tween-80作为W/O、O/W乳化剂,以液体石蜡作为油相制备W/O/W多重乳液;以乳液的分层率作为乳液稳定程度的标准,探讨了乳化剂种类、乳化剂质量分数及油水体积比对W/O/W多重乳状液体系稳定性的影响。借用旋转流变仪对乳液流变性能进行测定,探讨脂肪醇(CmH2m+1OH,m=12,14,16,18和20)、高聚物(黄原胶、羟乙基纤维素、小核菌胶)对W/O/W多重乳液流变性质的影响。结果表明稳定的W/O/W多重乳液较优组成,初级乳液(W/O):聚甘油-2-二油酸酯质量分数为10%,V(液体石蜡)∶V(水)= 2∶1;W/O/W多重乳液:十聚甘油单月桂酸酯质量分数为6%,V(初级乳液)∶V(水)=9∶10,脂肪醇(十六醇)质量分数为2%,高聚物(黄原胶)质量分数为0.15%。

Abstract:

The W/O/W multiple emulsion was prepared by using polyglycerol-2-dioleate and decaglycerin monolaurate instead of Span-80 and Tween-80 as W/O and O/W emulsifiers, respectively, and using liquid paraffin as the oil phase. The delamination rate of the emulsion was used as the standard for the stability of the emulsion. The effects of emulsifier type, emulsifier mass fraction and oil-water ratio on the stability of W/O/W multiple emulsion system were discussed. The rheological properties of the emulsion were measured by a rotary rheometer. The effects of fatty alcohols (CmH2m+1OH, m=12, 14, 16, 18, 20) and polymers (xanthan gum, hydroxyethyl cellulose, nucleocapsid) on the rheological properties of W/O/W multiple emulsions were investigated. The results show that the suitable W/O/W multiple emulsions has a superior composition. The primary emulsion (W/O): polyglycerol-2-dioleate has a mass fraction of 10%, and V(liquid paraffin)∶V(water)= 2∶1; W/O/W multiple emulsion: octaglycerol monolaurate mass fraction is 6%, V(primary emulsion)∶ V(water)=9∶10, fatty alcohol (cetyl alcohol) mass fraction is 2%, the high polymer (xanthan gum) mass fraction is 0.15%.

Key words: polyglycerol fatty acid ester, multiple emulsion, rheology, stability
