[0066] The preparation method of the cosmetic described in the fourth aspect of the present application, comprising:
[0067] Step 1, mixing phase B and phase A to obtain a powder slurry; wherein, the phase A includes an emollient, an emulsifier and a skin feel modifier, and the phase B includes a colorant and triple hydrophobic treatment titanium dioxide;
[0068] Step 2, heating phase D until each component is dissolved; wherein, the phase D includes a solvent, a moisturizing agent and a stabilizer;
[0069] Step 3. Mix the phase D with the slurry in the first step until emulsification, and then continue to add phase C and phase E to prepare cosmetics; wherein, the phase C includes alumina-based pearlescent powder and Absorbing silica, the E phase includes preservatives and solvents.
[0070] Specifically, the mixing in step 1 is ground by a three-roller mill, and the homogenization parameter is 6000 rpm for 10 minutes.
[0071] Specifically, in step 1, phase A is divided ...
Embodiment
[0088] The embodiment of the present application provides a variety of preparation methods of liquid foundation, specifically including:
[0089] The liquid foundations of Example 1 to Example 11 and Comparative Example 1 to Comparative Example 5 were prepared according to the formula in Table 1, and the specific steps included:
[0090]1) Phase B is pre-mixed with the first sub-phase A, and ground three times with a three-roll mill to prepare a uniform first mixture. Weigh the second sub-phase A and mix it with the above-mentioned first mixture, homogenize for 10 minutes, 6000 rpm, to prepare a slurry.
[0091] 2) Weigh the components of phase D, heat and stir at 85°C until the components are completely dissolved, cool down to room temperature for later use, and obtain the dissolved and mixed phase D; turn on the homogenizer (6000rpm, 5 minutes), and dissolve the mixed Add phase D to the above slurry three times until the emulsification is complete to obtain the second mixtu...
