distributed as droplets throughout the other.
Oil in Water emulsion (O/W), the oil is the dispersed phase and water is the dispersion medium. This type of
emulsion is preferable or preferred for internal use because the unpleasant taste & odour is masked by
emulsification. The aqueous phase constitutes > 45% of the total weight.
