[0147] According to the trial use of each volunteer on the corresponding long-lasting liquid foundation sample, summarize the use experience and irritation, and score the use experience (on a 10-point scale, with a full score of 10 points. The scoring results of each group are averaged according to the test values within the group). The summarized use experience effects are shown in Table 2:

[0148] Table 2

There is a tight feeling None 4.5 Comparative Example 6 The skin feeling is smooth, fresh and natural, fitting well, the makeup is easy to fade, and there is no sticky feeling None 6.5

[0150] From the test results in Table 1 and Table 2, it can be seen that the long-lasting liquid foundation of Examples 1-4 has a good user experience compared with the long-lasting liquid foundation of Comparative Examples 1-6. The skin feeling is smooth, comfortable, fresh and natural, adheres to the skin, and the makeup is long-lasting and non-greasy. It shows that the long-lasting liquid foundation of the present invention uses polydimethylsiloxane (and) acrylate / polymethyltrisiloxanyl methacrylate copolymer soft film resin film-forming agent and vinyl polydimethylsiloxane / polymethylsiloxane sesquisiloxane cross-linked polymer to form a film and fix the color. Combined with sodium hyaluronate (156W / Da) and tremella polysaccharide soft film-forming agent, the film-forming system film layer of the foundation composition can effectively improve the film-forming effect, reduce the tight feeling at the same time, enhance the skin adhesion, skin spreading property and texture, will not produce a greasy feeling, and enhance the long-lasting makeup effect; at the same time, the film-forming system has good compatibility with the emulsification system used, can keep the liquid foundation stable for a long time, and will not appear makeup removal phenomena such as powder floating during use.

[0151] The tremella polysaccharide in the formula contains natural active substances such as polysaccharides, proteoglycans, polyphenols, flavonoids, saponins, polypeptides, oligosaccharides, and amino acids. Among them, the polysaccharide substances contain hydrophilic groups with -COOH and -OH functional groups; sodium hyaluronate (156W / Da) is a hydrophilic macromolecule with -COOH and -OH functional groups, which has a high solubility in water and can form a high-viscosity solution. This characteristic makes it show unique film-forming properties and viscoelasticity. After sodium hyaluronate forms a film, its sodium ions are also very lubricating and soft. In addition, the film-forming agent is combined with polydimethylsiloxane (and) acrylate / polymethyltrisiloxanyl methacrylate copolymer soft film resin and vinyl polydimethylsiloxane / polymethylsiloxane sesquisiloxane cross-linked polymer composite silicon powder to quickly absorb oil and form a film.
