Cream Formulation with Glyceryl Stearate SE and Cetyl Alcohol
Question
How can I make a stable cream using only `Glyceryl Stearate SE` and `Cetyl Alcohol`?
Is it necessary to calculate HLB for this combination, or should I add other ingredients like a cream maker?
Answer
Based on the staff's response, using only Cetyl Alcohol and Glyceryl Stearate SE to create a stable cream requires calculating the HLB (Hydrophilic-Lipophilic Balance) of the formula.
The easier and recommended method is to use Cetyl Alcohol and Glyceryl Stearate SE in combination with another dedicated cream maker (emulsifier). In this approach, the added cream maker handles the emulsification (binding water and oil), while Cetyl Alcohol and Glyceryl Stearate SE primarily act as thickeners, giving the cream body and weight.
So, while it's technically possible to use just the two with proper HLB calculation, it's much simpler and generally recommended to include another emulsifier.
