| titleOfInvention | Method for preparing composition containing medicinal hydroquinone and auxiliary material |
| abstract | The invention provides a preparation method of a composition containing medicinal hydroquinone and auxiliary materials, which comprises the following steps: preparing water phase, adding purified water and glycerol into a water phase pot, continuously stirring, adding sodium dodecyl sulfate when the purified water and the glycerol are uniformly mixed, stirring until the purified water and the glycerol are completely dissolved, adding sodium bisulfite and hydroquinone, and stirring until the purified water and the glycerol are completely dissolved; preparing oil phase, putting cetyl alcohol or stearyl alcohol, liquid paraffin, white vaseline, and glyceryl stearate into oil phase pot, stirring, heating to melt, adding tert-butyl-p-cresol and propyl hydroxybenzoate, and stirring to completely melt; homogenizing and emulsifying, vacuumizing an emulsifying pot, pumping the water phase material prepared in the water phase preparation step into the emulsifying pot, adding the oil phase material in the oil phase pot into the emulsifying pot while stirring, starting the emulsifying pot homogenizer, and cooling to paste after homogenizing and emulsifying. The composition containing the medicinal hydroquinone and the auxiliary material prepared by the method has good freckle removing effect. |
