    Great presentation, thanks! I haven't used carbomers in any formulations yet but I'll keep this presentation in mind for when I do.

    Agreed! Interesting and oftentimes very helpful.
  • What is the advantage to add the carbomer in the oil phase? emulsion stabilization? better dispersion of the powder? How fast is the migration of the carbomer from the oil phase to the water phase?

    The advantage is that the carbomer doesn't hydrate yet, so it easier to disperse. I don't understand what you mean with carbomer migration?
    The carbomer starts hydrating as soon as the phases are combined.
  • I mean: if carbomer is dispersed in the oil phase, there is a kinetic of migration/hydration of the carbomer from the oil droplets to the water.
