The invention relates to the technical field of
skin care products, in particular to a preparation method of
sunscreen cream. The preparation method of the
sunscreen cream comprises the following steps: step 1, respectively selecting a proper amount of
rhodiola rosea,
polygonum cuspidatum, roses and
green tea, crushing, and then respectively adding 70%
ethanol with a
solid-
liquid ratio of 8-15 times to the
rhodiola rosea, the
polygonum cuspidatum, the roses and the
green tea; step 2, taking a
rhodiola rosea extracting solution, a
polygonum cuspidatum extracting solution, a rose extracting solution and a
green tea extracting solution as
plant compound solutions; 3, preparing a proper amount of 1%
sodium ethylene diamine tetracetate solution as a water phase; 4, selecting a proper amount of
titanium dioxide,
stearic acid, C16-C18
alcohol,
vaseline,
olive oil,
methylparaben and the
plant compound liquid as raw materials, heating in a water bath, stirring to form an
oil phase, and then adding the mixed emulsifier; step five, adding the
oil phase into the water phase while stirring, and then carrying out homogeneous emulsification by using a
homogenizer; and 6, carrying out
thermal insulation emulsification for 20 min, cooling to 50 DEG C, adding essence, fully stirring, cooling to
room temperature (25 DEG C), stopping stirring, and carrying out discharging and filling.
