Queries about cream formulation
I’m very new to doing O/W topical face cream formulations, and am wondering about a few things. I heard from another formulator that the emulsion should be left to settle and age a bit after it has been made before doing any analyses on it - particle size measurements, and accelerated temperature testing. My question is - how long should I leave it to settle and age after making it please? Does this vary from emulsion to emulsion depending on what is in the formulation and if so, what should I be looking at to help me decide how long to age the emulsion before bringing it forward for further testing? Thanking you in advance for the guidance!
