Incompatibility of Willow Bark Extract with Aristoflex AVC Gel Maker

It appears the issue you encountered with your gel becoming liquid after adding Willow Bark Extract when using Aristoflex AVC is likely due to the incompatibility between the two ingredients.

Willow Bark Extract contains natural salicylic acid, which is acidic. Some gel-forming polymers, including Aristoflex AVC, can be sensitive to low pH environments or the presence of certain electrolytes or acidic ingredients. This sensitivity can cause the polymer structure to break down, leading to a loss of viscosity and the gel becoming liquid.

While Aristoflex AVC may not be suitable for use with Willow Bark Extract, Willow Bark Extract itself is compatible with many other types of gel bases. As the staff reply indicated, you can successfully incorporate Willow Bark Extract into gels created with other gelling agents.

Compatible gel makers that work well with Willow Bark Extract include:

• Pro Polymer
• Pro Polymer Silk
• AnyGel
• Xanthan Gum

Using one of these alternative gel bases should allow you to create a stable gel formulation with Willow Bark Extract.
