Ichthammol Formulation: Necessity of Oil/Wax for Skin Penetration

Based on the discussion:

• Ichthammol can be mixed in water, glycerin, or alcohol.
• While it is not strictly necessary to include oil or wax in the formulation, doing so is recommended.
• Adding oil or wax helps Ichthammol penetrate the skin more easily, potentially leading to better results.
• Formulations without oil or wax can still be effective, but the skin penetration might not be as good as formulations that include oil or wax.

Therefore, your understanding is correct: it is okay to formulate without oil or wax, but including them will help Ichthammol penetrate the skin better.
