Gel Formation for BHA Timed-Release and Witch Hazel

Based on your question and the previous discussion, here is the guidance for creating gel textures for your separate formulations:

For BHA Timed-Release (Encapsulated Salicylic Acid)

When working with BHA Timed-Release or Encapsulated Salicylic Acid, the compatible gel-forming agent is Hydroxyethyl Cellulose (HEC). Other thickeners, such as Pro Polymer, are not compatible with this type of BHA.

Using Hydroxyethyl Cellulose will allow you to create a stable gel texture for your BHA Timed-Release formula.

For Witch Hazel

For a formula containing Witch Hazel, you have more flexibility. You can use various gel-forming agents, including Pro Polymer.

Since you are creating separate formulas and not combining BHA Timed-Release and Witch Hazel in the same product, you can choose the appropriate thickener for each specific formula based on compatibility and desired texture.

To achieve a gel that is not too liquid, adjust the concentration of the chosen thickener according to the product's usage instructions and your desired viscosity.
