[0042] How to prepare mascara:

[0043] S1. Mix microcrystalline wax, VP / eicosene copolymer, trihydroxystearin, stearyl inulin, hydrogenated polyisobutene and isododecane, stir at 85-90°C until dissolved, weigh and calculate Isododecane is volatilized and lost, and the isododecane lost by volatilization is supplemented to obtain phase A;

[0044] S2. Disperse trimethylsiloxysilicate and dimethylsilyl silica in sequence in cyclopentasiloxane at a rotational speed of 800-15000rpm / min to obtain phase B, Add phase B to phase A and disperse evenly;

[0045] S3. Put preservatives, silica, thickeners, and colorants into phase A + phase B in sequence, and stir at a speed of 3000-6000rpm / min for 4-7min, then grind them evenly, and put them at 50-60°C Add rayon fibers and cellulose, stir evenly at a rotating speed of 2000-4000rpm / min, cool down to 30-35°C, and obtain the mascara.

[0048] S1. Heat microcrystalline wax, VP / eicosene copolymer, trihydroxystearin, stearyl inulin, hydrogenated polyisobutene, and isododecane to 85-90°C to dissolve completely, and weigh to calculate isododecane The volatilization of dioxane is lost, and the isododecane lost by volatilization is replenished to obtain phase A;

[0049] S2. Under the stirring state, the rotation speed is 1000rpm / min, and trimethylsiloxysilicate and dimethylsilyl silica are dispersed in cyclopentasiloxane in turn until the solution is half Transparent, get B phase, add B phase to A phase and disperse evenly;

[0050] S3.
