Answer
Mixing Activated Resorcinol™ into a Cream with Propylene Glycol
Based on the product information for Activated Resorcinol™ (4-Butyl Resorcinol), it is stated to be soluble in oil. While Propylene Glycol is a solvent, the description for Activated Resorcinol does not explicitly confirm its solubility in Propylene Glycol.
Directly adding the Activated Resorcinol powder into a cream that contains Propylene Glycol but no oil phase where the Activated Resorcinol is known to dissolve may not result in proper dissolution and dispersion. This could potentially affect the stability of the cream and the effectiveness of the Activated Resorcinol.
For best results and stability, it is generally recommended to ensure that Activated Resorcinol is fully dissolved in a suitable solvent (such as an oil, as suggested in its product description) before incorporating it into a formulation. If your existing cream does not contain an oil phase, directly mixing the powder might not be the most effective method.
