Stability Studies. Accelerated stability studies in the
cosmetic area have been performed in periods of 30 to 90
days . For stability studies, samples were weighed (50 g)
and packed in glass containers with 100 g of content capacity.
Samples were kept in incubation chambers, each preset at
different storage temperature for a period of 30 days and this
testing was called “the accelerated storage period” which is
the time between the preparation ofmultiple emulsion and its
physicochemical investigation. Glass containers were chosen
to accelerate the conditions and hence to accelerate the destabilization
of multiple emulsions. Different storage conditions
were room temperature (25 ± 1
∘C),
