Question

How to dissolve MSH White in a serum formulation? Is 5% Ethoxydiglycol sufficient, or is oil also needed?

Answer

Based on the feedback provided, you can use Ethoxydiglycol to dissolve MSH White. However, the proposed concentration of 5% Ethoxydiglycol is likely insufficient for long-term stability and may lead to MSH White precipitating. It is recommended to increase the Ethoxydiglycol concentration to approximately 8% to ensure proper dissolution and stability of MSH White in the serum. You do not necessarily need to use oil for this purpose if using Ethoxydiglycol at the recommended concentration.
