Dissolving Whitening Ingredients with Perfect-C for Pump Bottle Formulation

Based on the staff's response:

1. Can Perfect-C dissolve MSH White and Activated Resorcinol completely?
   The staff believes complete dissolution is possible, but it requires heat, ideally between 60-70°C. MSH White might be harder to dissolve, so it's recommended to test with a lower concentration (0.5%) first before adding the full amount.
2. Can MSH White be dissolved without using heat?
   The staff's response implies that heat is necessary for complete dissolution, especially for MSH White. While not explicitly stated that it's impossible without heat, the recommendation to use heat suggests it is required for this formulation.
3. Can the resulting formulation be put into a pump bottle?
   Yes, the staff confirms it can be put into a pump bottle. The resulting texture will not be too thick, similar to a standard Nivea lotion.
