SKIN LIGHTENING CREAM

Description
OBJECT: Prepare water phase of viscous cream and then emulsify oil phase into water phase.
PROBLEM: Low shear does not produce a fine enough particle size distribution.
RESULT: By metering oil phase into water phase, the emulsion is allowed to gradually build up oil phase fraction as an o/w emulsion until the inversion point arrives and a fine grain w/o emulsion is the result.
