Solubility and Mixing of Activated Resorcinol in a Whitening Serum Formula
คำถาม
I want to create a serum to address melasma, freckles, dark spots, acne marks, and dull skin. I have the following formula:
- Activated Resorcinol 1%
- Ume Extract 2%
- Tranexamic Acid 3%
- Gluco Bright 4%
- Niacinamide 5%
- Azelaic Acid 10%
- Double Hyaluronic 10%
- Dimethyl Isosorbide (DMI) 3%
- Xanthan Gum 0.2%
- Mild Preserved Eco 1%
- Water (remaining part)
Can Activated Resorcinol be mixed directly into this formula, or does it require a solvent for dissolution?

Activated Resorcinol Solubility in Serum
Based on the product information, Activated Resorcinol is oil-soluble and cannot be directly dissolved in the water phase of your serum formula.
To incorporate Activated Resorcinol into a water-based formula like your serum, it typically needs to be dissolved in an oil or a suitable solvent first. The product description specifically states that it is soluble in oil.
Mixing it into a serum would likely require dissolving it in a small amount of oil or a compatible solvent and then using an appropriate method (like an emulsifier, depending on the desired serum texture) to ensure it remains stably dispersed within the water base. Simply adding the powder directly to the water phase will not work as it will not dissolve.
Please note that the optimal pH range for Activated Resorcinol is 4.5-5.5, and Disodium EDTA is recommended at 0.2% to help prevent discoloration. Avoid using heat during mixing as it can cause the ingredient to deteriorate. The maximum recommended usage rate for leave-on products is 1%.
