Dear forum,
I work for a cosmetic company and I carry out challenge testing on "oil in water" emulsions. There is a need to perform challenge tests on "water in oil" products. I use a rich broth that contains polysorbate 80 at a concentration of 5%. Although the Method Suitability test shows that the concentration of polysorbate in the broth is suitable for testing these "water in oil" emulsions, I cannot see the product being dissolved in the broth. Is it possible to tell me how they could be dissolved?
Any thoughts would be grateful,

Thank you in advance,
Giolina Chavella
