Abstract:

The effects of thickeners and processes on the product properties of emulsion systems were studied, in which sucrose polystearate was used as an emulsifier. The physical and chemical properties, the size distribution of droplets and the stability of the samples were analyzed to evaluate the emulsification efficiency of sucrose polystearate in presence of different thickeners. In this study, two categories of thickeners were used, including neutralizable ones such as Pemulen TR-1, Carbopol Ultrez 21, and Carbopol Ultrez 30, and non-neutralizable ones such as Aristoflex AVC, SEPIMAX ZEN, and Aristoflex BLV. The experimental results indicated that, those neutralizable thickeners pre-added into the system had significantly reduced the emulsifying ability of sucrose polystearate, resulting in the formation of emulsions with larger particle size and uneven distribution. In contrast, no significant influence was observed for non-neutralizable thickeners upon the emulsifying ability of sucrose polystearate. Therefore, for neutralizable thickeners, it was recommended to incorporate them into the system in a dispersion form after the emulsification process, during the low-temperature stage, and with appropriate mixing intensity, thus to prepare products with smaller particle size, good stability and fine appearance. This study revealed the influences of selection and addition of thickeners, which might provide new ideas and methods for application of thickeners in emulsion systems. It could be helpful for the design and optimization of thickeners and emulsion systems.
