Patent ID: 8790738

Claim:
A process of preparing a burdock composite micron essence, comprising Step 1 of mixing: phospholipid is dissolved and heated and then added to a vegetable oil blend and then stirred to obtain a mixture; after stirring, the mixture is poured into heated glycerol and further stirred; and a burdock extract aqueous solution is added to obtain a mixed solution; Step 2 of emulsion homogenizing: the mixed solution from Step 1 is stirred at high speed to obtain an emulsion-homogenized solution; Step 3 of homogenizing: the emulsion-homogenized solution is subject to high-pressure homogenization to obtain a homogenized solution; and Step 4 of filtering: a filtration membrane is used to filter the homogenized solution obtained at Step 3 to get a purple transparent burdock concentrate wherein the filtration produces a micron essence.
