High Shear Mixing for Trihydroxystearin in Oil Phase
Question
Regarding the use of Trihydroxystearin in the oil phase to achieve thixotropic thickening, the instructions indicate using 'High shear'. I would like to clarify:
- Should a homogenizer (Homo head) be used to achieve this high shear?
- Or is a propeller stirrer sufficient for this process?
Please also consider the optimal temperature range (65-100 degrees Celsius) for dissolving and dispersing Trihydroxystearin effectively.
Answer
For Trihydroxystearin, which provides thixotropic thickening, using high shear is crucial for proper dispersion and achieving the desired viscosity and stability in your oil phase.
While a propeller stirrer can be used for initial mixing and dispersion, a homogenizer (Homo) is recommended for applying the necessary high shear. A homogenizer will ensure that Trihydroxystearin is thoroughly dispersed and fully activated, leading to a more uniform and stable thick gel, especially given its thixotropic properties where viscosity changes with shear force.
Remember to control the temperature between 65-100 degrees Celsius during mixing to help dissolve and disperse the Trihydroxystearin effectively.
