Mixing Tranexamic Acid with Skin Barrier Cream Base

Yes, you can mix Tranexamic Acid with the Skin Barrier Cream Base. However, since Tranexamic Acid is a powder that needs to be dissolved in water, and the Skin Barrier Cream Base is an emulsifier-free base, there is a potential risk of separation.

Here's how you can approach it and what to consider:

1. Dissolve Tranexamic Acid: Tranexamic Acid should first be fully dissolved in the water phase of your formula. You can use a small amount of distilled water for this.
2. Incorporate into the Base: Once dissolved, carefully incorporate the Tranexamic Acid solution into the Skin Barrier Cream Base. The base is designed to accept additional ingredients.
3. Risk of Separation: The Skin Barrier Cream Base is formulated without traditional emulsifiers to be gentle on the skin barrier. Adding a significant amount of an external water phase (the Tranexamic Acid solution) can potentially disrupt the base's structure and lead to separation. The higher the concentration of the water phase you add, the greater the risk.
4. Recommendation: It is highly recommended to test mixing with a small batch first to check for stability and separation before making a larger quantity. Ensure thorough but gentle mixing to help maintain the base's structure.

In summary, mixing is possible, but be mindful of the potential for separation due to the nature of both ingredients and the base.
