Abstract:
1. A method for preparing an oil-in-water (O/W) type nanoemulsion composition, comprising: heating an oil phase component to 75° C., wherein the oil phase component consists essentially of a mixture of triethylhexanoin, cetyl ethylhexanoate, dimethicone, cetearyl alcohol, PEG-20 glyceryl isostearate and PEG-40 glyceryl isostearate; heating a polyol or polyol derivative to 75° C., wherein the polyol or polyol derivative consists essentially of a mixture of glycerin and butylene glycol; introducing the oil phase component to the polyol or polyol derivative to form an oil-in-polyol (O/P) type gel; adding an aqueous phase component to the O/P type gel, followed by agitation; and cooling the agitated components, wherein the nanoemulsion has an average particle size of 10-500 nm.
