The invention discloses a freeze-dried
blusher composition and a preparation method thereof, and belongs to the technical field of
cosmetics. The composition comprises a filler, a water phase, an emollient and an emulsifier, the filling agent is one or more of
modified starch, synthetic fluorophlogopite,
boron nitride and the like; the water phase is deionized water, a
humectant and the like; the emollient is a
polydimethylsiloxane derivative,
jojoba oil and the like; and the emulsifier is
sorbitan stearate and the like. The preparation method comprises the following steps: weighing the raw materials, crushing and mixing the filler into a phase A, heating a water phase into a phase B, and dissolving the emollient and the emulsifier into a phase C; emulsifying, homogenizing and cooling the phase C and the phase B into a phase D, and mixing and pressing the phase A and the phase D; performing vacuum
freeze drying, including pre-freezing, sublimation
drying and heating
drying, and finally performing constant-temperature and constant-
humidity storage. The embodiment shows that the water
loss rate of the composition is 2.5-4%, the
hardness is low, the stability is high, the smoothness, the
ductility, the
skin fitting degree and the coloring property are superior to those of a contrast, the preparation time is 12.87-17.7 h, the
energy consumption is reasonable, and the composition has a good market prospect.
