Question
I would like to inquire about the ingredient WhiteCumin™ powder. This specific grade is described as being soluble in oil and glycol.
The chemical name for WhiteCumin™ is Tetrahydrodiferuloylmethane, extracted from high-purity turmeric for cosmetic use.
My question is: Is Glycol considered part of the Water Phase (Aqueous Phase) in a cosmetic formulation?
Answer
Yes, glycols (such as Propylene Glycol, Butylene Glycol, and Glycerin) are generally considered part of the water phase (Aqueous Phase) in cosmetic formulations.
Here is the explanation:
- Water-Miscibility: Glycols are highly water-miscible, meaning they mix completely with water. Therefore, they are incorporated into the water phase when preparing an emulsion (like a cream or lotion).
- Solvent/Carrier Role: For ingredients like WhiteCumin™ (Tetrahydrodiferuloylmethane), which is a powder soluble in oil and glycol, the glycol acts as a solvent or carrier. By dissolving the WhiteCumin™ powder in a small amount of glycol first, the active ingredient is effectively dispersed and incorporated into the overall water phase of the formulation. This is a common technique for incorporating ingredients that are not directly soluble in pure water but are soluble in water-miscible solvents.
