Adding Panthenol to Oil Soap Formula for Dry Skin

Question

Regarding a formula based on Oil Soap (likely MIPA Laureth Sulfate) intended for very dry/itchy skin: Can Panthenol (Pro Vitamin B5) 1.5% be added to this formula? If yes, what is the correct procedure for adding it? Will adding Panthenol (Pro Vitamin B5) at this percentage be effective for moisturizing very dry/itchy skin in this type of wash-off formula?

Regarding your question about adding Panthenol (Pro Vitamin B5) to your modified Oil Soap formula:

Can Panthenol be added? Yes, it can be added.
How and when to add? Dissolve the Panthenol in the water component (2%) first, and then add this mixture to the rest of the formula.
Expected effect: Please note that in a wash-off product like soap, the moisturizing effect of Panthenol on very dry/itchy skin is expected to be minimal as it will be rinsed off immediately.

The staff also previously commented on your modified formula regarding the high percentage of Cocoa Butter (11%), which might cause the formula to become cloudy or thicken at room temperature, and the low percentage of water (2%).
