    I need some help. I am using titanium dioxide dispersion for my sunscreen formulation. After formulating I did a centrifuge test to check on the stability and found that my formulation always separates and there is a white layer. I suspect that is the titanium dioxide. I was wondering if I can still do centrifuge test when using titanium dioxide dispersion?

    Probably not, if you are looking at emulsion stability

    Conduct a standard stability test.

    by standard stability test you are referring to 5C, room temperature and 45C?

    No, centrifuges are mostly useless for determining stability.
