Producing aqueous emulsion of oily active substance e.g. for cosmetic, comprises homogenizing mixture of hydrophilic components comprising water and saponoside emulsifier, and mixture of oily lipophilic components of oily active substances

摘要

Producing an aqueous emulsion of an oily active substance, comprises homogenizing a mixture of less than 1% of hydrophilic components comprising water and a saponoside emulsifier, using standard rotor-stator mixer, or with ultrasounds, until obtaining an average diameter of oil droplets of less than 6 mu m and homogenizing a mixture of 40% of lipophilic components comprising oily active substance using a homogenizer with high pressure, until obtaining an average diameter of less than 0.4 mu m of oily droplets. Independent claims are included for: (1) the aqueous emulsion produced by the method; and (2) a gel or a cream comprising the emulsion and a thickener.
