Embodiment 1

[0298] Example 1-Foundation test

[0299] preparation

[0300] A high-speed mixer was used to prepare the foundation of the present invention Example 2, Comparative Example 3 and Comparative Example 4. Add all polymer to the high speed mixer cup. Mix the sample at 2500-3500 RPM until homogeneous. The sample is usually opaque and not clear, and the uniformity is recognized by the smoothness of the sample. In addition to the appropriate amount of solvent, add pigment, pigment dispersion, and any other particles to the freshly mixed sample. In addition, mix the sample at 2500-3500 RPM until uniform. The ingredients are shown in the table below.

Embodiment 2

[0316] Example 2-Base Makeup Test

[0317] preparation

[0318] A high-speed mixer was used to prepare the base makeup example. Add all polymer to the high speed mixer cup. Mix the sample at 2500-3500 RPM until homogeneous. The sample is usually opaque and not clear, and the uniformity is evaluated by the smoothness of the sample. Add filler particles to the freshly mixed sample. Mix the sample again at 2500-3500 RPM until homogeneous.

Embodiment 3

[0333] Example 3-Anhydrous composition

[0334] Sample Preparation: The composition was prepared using a high speed mixer. Add all polymer to the high speed mixer cup. Mix the sample at 2500-3500 RPM until homogeneous. The sample is usually opaque and not clear, and the uniformity is recognized by the smoothness of the sample. In addition to the appropriate amount of solvent, add pigment, pigment dispersion, and any other particles to the freshly mixed sample. In addition, mix the sample at 2500-3500 RPM until uniform.

[0335] Membrane rupture and recovery: Evaluate the dry film properties of the sample. The sample was cast on BYK opaque recording paper (#2812) at room temperature using a 3mil wet drafting bar. Allow the sample to dry for a minimum of 5 hours. After drying, the phase separation and self-homogenization properties of the samples were evaluated visually and manually. To assess phase separation, the membrane was agitated with gloved fingers. Record if the s...
