How to Create Cream Texture with Silicone Gel Base and Glyceryl Stearate SE

Based on the information from the staff and product details, to create a cream texture using Silicone Gel Base and Glyceryl Stearate SE, it is recommended to use Glyceryl Stearate SE together with Cetyl Alcohol.

Both Glyceryl Stearate SE and Cetyl Alcohol are ingredients that require heat to melt and help form an emulsion. Therefore, you generally need to heat the mixture.

General Process:

  1. Combine your Silicone Gel Base with Glyceryl Stearate SE and Cetyl Alcohol in the oil/silicone phase.
  2. Heat this oil/silicone phase and the water phase separately to a temperature sufficient to melt the emulsifiers (typically around 60-75°C).
  3. Slowly add the heated water phase to the heated oil/silicone phase while stirring continuously.
  4. Continue stirring until the mixture cools and thickens into a cream.

Using Cetyl Alcohol alongside Glyceryl Stearate SE helps to stabilize the emulsion and contribute to the cream's texture. Finding the right ratio might require some testing or HLB calculation, although the staff noted that HLB calculation can be complex for DIY.

As an alternative, the staff also suggested using easier-to-work-with emulsifiers like Sepimax Zen or Sepinov EMT10, which are polymer-based and often do not require heating or HLB calculation, making the process simpler and less prone to separation.
