Abstract:

The effects of emulsifiers on the preparation of low-viscosity emulsions were studied. The long-term thermal stability of low-viscosity emulsions was monitored by investigating their rheological properties. The results show that cetearyl alcohol polyether emulsifier is suitable for preparing low-viscosity emulsions. For oil-in-water emulsifiers, given the same lipophilic group, the shorter the EO chain length, the better the yield stress and the centrifugal stability of the resulting emulsion. There is an optimal amount for cetearyl alcohol polyether emulsifier when it is solely used as the emulsifier. Its emulsifying property is good. The yield stress of the low-viscosity emulsion is significantly higher when cetearyl alcohol polyether emulsifier is combined with a low-HLB nonionic emulsifier, and the resulting particle size is smaller. It is highly likely due to the stronger interfacial film strength in the presence of two emulsifiers, because the emulsifier is the only variable in the studied emulsions.

Key words: fatty alcohol polyether emulsifier, EO chain length, yield stress, rheology, stability
