FORMULATION ADVICES
Laboratory scale - 2000 g - Homogenizer & Sweeper
Combine phase B ingredients and heat it up to 40 ̊C to melt polyhydroxystearic acid. Then add phase C ingredients one by one into B while homogenizing at 5000 rpm. Once phase C is added, homogenize at high shear if needed for more minutes. When phase (B+C) is properly dispersed and uniformed, stop homogenizing and then add phase D and heat to 85 ̊C. Heat aqueous phase A to 85°C. Heat up oily phase (B+C+D) up to 85°C, then add phase E. Combine oily and aqueous phases together and homogenize at 4,000 rpm for 4 minutes. Cool down the batch with low shear mixing to 60°C and add phas F, then cool down the batch to RT.v
