Cosmetics Formulation Development

The texture of the product is all powdery. with the following ingredients Menthol 4% Aluminum sulphate 76% rice sorb 20% for the purpose of adding rice sorb so that the alum does not clump together. I would like to know if the amount of rice sorb is appropriate or not? And is it possible not to wear สารกันเสีย in the product. some (Want to be natural) Thank you for your answers in advance.

Hello, the team is not sure. because never used RiceSorb in a formula like this before. Recommend members to test for สารกันเสีย in the formula. like this If packing in sealed packaging do not need to fill สารกันเสีย , but packaging must protect the product from dirt. outside is fine

Can you suggest a method for testing? Which test should I do or where should I send the test?

like the company used to have สารกันเสีย powder type name nature preserve Available for sale but not available at the moment. already

Hello, if this formula wants to add สารกันเสีย must be sprayed and tumbled dry. สารกันเสีย spread throughout the formula. สารกันเสีย in powder form Must be dissolved and then sprayed to be fully effective. If blended in powder form with the formula, it will not be as effective as it should be. because it hasn't been dissolved yet. Inquire about the nature of the packaging Or request a sample of the packaging that will contain the product for sale. The staff will help suggest that it is to enter สารกันเสีย or not. If necessary, in what format and how?
