▎ 摘　　要

NOVELTY - Preparing differential epigenetic involves mixing an oxalic acid solution, a hypochlorous acid solution, a bismuth vanadate, a graphene oxide, a zinc oxide, a rutile titanium oxide, and a hydrotalcite for hydrothermal reaction. After grinding, filtering, calcining, washing, drying, to obtain epigenetic special. The anti-aging agent, ethylene glycol, propylene glycol, glycerin, lactic acid, epigenetic special anti-aging agen, silica, mica powder and potassium hydrogen phosphate dispersion are mixed, ground, dispersed, and filtered to obtain differentiated epigenetic mother liquor. The differential epigenetic mother liquor is sprayed into epigenetic to prepare differentiated epigenetic. USE - Method for preparing differential epigenetic. ADVANTAGE - The method enables to prepare differential epigenetic which has excellent anti-aging function.
