O/W NANO-EMULSION WITH HIGH EMULSION STABILITY, PREPARATION METHOD THEREOF, AND COSMETIC COMPOSITION COMPRISING THE SAME

摘要

PURPOSE: An oil-in-water type nanoemulsion with excellent emulsion stability, a method for preparing the same, and a cosmetic composition containing the same are provided to improve stability of a nanoparticles, and to maintain particle size for long term. CONSTITUTION: An oil-in-water type nanoemulsion contains an oil phase part in which an aqueous phase part is dispersed and contains an oil sphere with an average size of 150nm or less. The nanoemulsion contains a vegetable emulsifier containing polyglyceryl-3-methyl glucose distearate, cetearyl glucoside, and methyl glucose sesquistearate. The vegetable emulsifier contains 1 part by weight of methyl glucose sesquistearate, 3.3-5.5 parts by weight of polyglyceryl-3-methyl glucose distearate, and 0.5-1 parts by weight of cetearyl glucoside. A cosmetic composition contains the oil-in-water type nanoemulsion.
