Bakuchiol Solubility in Water-Based Gel

Regarding your question about dissolving Bakuchiol in Glycerin for a water-based gel formulation:

Based on the product information, Bakuchiol is oil-soluble, not water-soluble. Glycerin, on the other hand, is water-soluble and typically mixed into the water phase of a formulation.

Therefore, Bakuchiol will not dissolve directly in Glycerin or in the water phase of your gel.

To incorporate Bakuchiol into a water-based gel, you would typically need to dissolve it in a suitable oil or solvent first. The product descriptions for Bakuchiol suggest dissolving it in oil. They also recommend using Dimethyl Isosorbide (DMI) as a penetration enhancer and solvent, which can help incorporate Bakuchiol into formulas that contain water, provided the pH is adjusted correctly (ideally 3.5-6.5).

In summary, while Glycerin is a useful ingredient in water-based gels for its humectant properties, it cannot be used to dissolve Bakuchiol. You will need an oil or a specific solvent like Dimethyl Isosorbide to solubilize Bakuchiol before adding it to your gel base.
