preparation example Construction
[0048] This example also provides a corresponding preparation method for the cosmetic pure oily color paste with high pigment content composed of the above-mentioned components according to the corresponding ratio. The preparation method comprises the steps of:
[0049] (1) Take each component according to the following parts by weight:
[0050]
[0051] Mix oil, dispersant, thickener, and stabilizer, heat and stir to obtain a uniform oily dispersion medium; the heating temperature here is 80-85°C.
[0052] (2) While heating and stirring the oily dispersion medium obtained in step (1), add 65-85 parts of pigment to disperse and mix into a slurry; the heating temperature here is 80-85°C.
[0053] (3) Disperse the slurry obtained in step (2) for 3-4 times by grinding and dispersing equipment to obtain the desired cosmetic oily color paste with high pigment content. The grinding and dispersing equipment here is at least one of a ball mill, a colloid mill, and a high-speed sh...
