Description

Technical Field

[0001] This invention relates to the field of cosmetics, specifically to a cosmetic composition, its preparation method, and its application. Background Technology

[0002] More and more consumers are concerned about uneven skin texture and visible pores, especially around the nose and cheeks, particularly those with combination or oily skin. As skin ages, pores become more noticeable. Pore-concealing products have emerged on the market, but current products often rely on silicone-based formulas. Most pore-refining products depend on volatile silicone oils such as cyclopentamethoxysiloxane (D5) and silicone elastomers like polydimethylsiloxane / vinyldimethylsiloxane cross-linked polymers to achieve an instant soft-focus effect through physical filling. However, this method has drawbacks: pores become visible again after the silicone oil evaporates, and long-term use may lead to clogged pores and even enlarge them. Silicone compounds are also difficult to biodegrade, and the EU REACH regulation has restricted the use of D5.

[0003] However, silicone-free solutions often suffer from insufficient efficacy. For example, simple astringent formulas (such as witch hazel extract) only temporarily shrink pores and do not provide optical coverage. Powder-filling formulas (such as talc / mica) tend to clump and cake around pores, exaggerating unevenness. Active ingredient formulas (such as retinol) require continuous use for 3-6 months to see results and lack immediate makeup effects.

[0004] Pore ​​minimizing requires meeting two core needs simultaneously (based on consumer research and dermatologist consensus): immediate effect – forming a matte film after application, providing immediate pore coverage; and long-lasting improvement – ​​continued use improves both the area and number of pores.

[0005] Invention patent CN112107518A discloses a cosmetic composition and its preparation method that provide pore coverage and long-lasting effect. While achieving pore coverage that lasts all day, the formula contains D4 / D5 silica rings (environmentally toxic) and does not provide long-lasting pore-improving effects. Invention patent CN 118021668A discloses a composition, its preparation method, and its application that inhibits sebum secretion and shrinks pores. The combination of multiple natural plant extracts can achieve long-lasting oil control and pore shrinking, but it lacks optical modification capabilities and does not provide immediate pore concealment.

[0006] The visual enlargement of pores is essentially due to an imbalance in light scattering. The difference in refractive index between the stratum corneum at the pore edge (1.55) and the sebum inside (1.47) creates light scattering and produces shadow areas. The dermal structure surrounding the pores provides structural support for the pores and the related hair follicle structures below them. This dermal support keeps the pores narrow, while damage to the dermis increases pore size. Physical enlargement of pores requires targeting the papillary layer of the dermis.

[0007] Therefore, it is necessary to provide a silicone-free product that can instantly conceal pores and provide long-lasting improvement in pore size. Summary of the Invention

Figure 3 Five subjects were tested for pore size in the test area before using Example 4. From left to right, they are Subject 1, Subject 2, Subject 3, Subject 4, and Subject 5. Figure 4 The pores in the test area were examined on five subjects after using Example 4. From left to right, they are Subject 1, Subject 2, Subject 3, Subject 4, and Subject 5.

[0191] Before use, the average number of pores per subject in the 30 participants was approximately 510.80. After use, the average number of pores was approximately 383.00, a decrease of 25.02% compared to before use.

[0192] Long-lasting (2W) effect in minimizing pores;

[0193] Test Sample: Example 2

[0194] Testing instrument: Visia-CR; Testing method: 30 volunteers were selected. After washing their faces, they rested for 15 minutes in a room with constant temperature and humidity. Before the test: Subjects washed their faces with facial cleanser and rested for 15 minutes in a room with constant temperature and humidity.

[0195] ① Take a facial photograph using Visia-CR before using the sample. ② Use the sample daily according to the instructions.

[0196] ③ After using the sample, take facial photos using Visia-CR.

[0197] Judgment criteria: The greater the reduction in the number and area of ​​skin pores, the better the sample's effect in concealing pores.

[0198] The test results are as follows:

[0199] Before use, the average number of pores per subject in the 30 participants was approximately 325. After use, the average number of pores per subject was approximately 298, a decrease of 8.31% compared to before use.

[0200] Before use, the average pore area of ​​each of the 30 subjects was approximately 0.221 mm. 2 After use, the average pore area is approximately 0.167mm. 2 Compared to before use, it decreased by 24.43%.

[0201] Sensory evaluation

[0202] A panel of 15 cosmetics evaluation experts evaluated Experiment 1, Experiment 2, Experiment 3, Experiment 4, and Comparative Example 1 on the sensory experience of the "silicone-like" feel and its effectiveness in instantly concealing pores. The evaluation was conducted using a scoring system (0-5 points), with higher scores indicating better results. The evaluation scale was as follows: 1 point - very dissatisfied, 2 points - somewhat dissatisfied, 3 points - average, 4 points - somewhat satisfied, 5 points - very satisfied.

[0203] Table 2

[0204] ;

[0205] Table 2 shows that sodium polyacrylamide dimethyl taurate plays a major role in whether the product has a silicone-like smooth feel and soft-focus effect. When used in combination with other specific thickeners, the powdery feel is more prominent, and the silicone-like smooth feel and soft-focus effect are better. Furthermore, when used in combination with other specific thickeners, while the amount of the other specific thickeners remains constant, the silicone-like smooth feel and soft-focus effect are improved to some extent with increasing sodium polyacrylamide dimethyl taurate content. Examples 2, 3, and 6 all exhibit a silicone-like smooth feel and soft-focus effect, while Comparative Example 1 shows no obvious silicone-like smooth feel and soft-focus effect.

[0206] In a single-use skin test conducted by a panel of cosmetic evaluation experts, the products of Example 2 and Comparative Example 1 were evaluated for their silicone-like silky smoothness, elasticity, matte soft-focus finish, adherence, and breathability. The evaluation was conducted using a scoring system (0-5 points), with higher scores indicating better results. The evaluation scale was as follows: 1 point - very dissatisfied, 2 points - somewhat dissatisfied, 3 points - average, 4 points - somewhat satisfied, 5 points - very satisfied.

[0207] The results are shown in Table 3 below.
