Description

Technical Field

[0001] The present invention belongs to the technical field of cosmetics, and particularly relates to a long-lasting oil-control loose powder and its preparation method and application. Background Art

[0002] With the acceleration of the modern life rhythm, especially for users with oily skin and office workers who work in front of the computer for a long time, maintaining a stable makeup for a long time has become a challenge. Oily skin is prone to secreting excessive oil during daily activities, resulting in easy makeup smudging, dullness, and even a shiny face. Therefore, oil-control loose powder has become an important tool in the daily makeup of these groups, aiming to extend the durability of makeup and effectively control the facial oil secretion. However, in the actual use process of the existing oil-control loose powder products on the market, there are often insufficient oil-control capabilities. Some loose powders fail to effectively adsorb in the case of more oil, resulting in the accumulation of facial oil, greasy feeling or caking on the makeup surface. Seriously, it will affect the uniformity of the makeup, making the makeup look thick and obvious floating powder, affecting the use effect.

[0003] In addition, when working in front of the computer for a long time or in a high-temperature environment, the facial oil secretion intensifies, and the oil-control effect of traditional loose powder often cannot last long enough, resulting in problems such as uneven and floating makeup.

[0004] Therefore, how to develop a makeup setting product with long-lasting oil-control effect and capable of maintaining uniform application and avoiding caking phenomenon under high oil conditions has become an urgent technical problem in the current cosmetics field. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the above-mentioned existing technologies and provide a long-lasting oil-control loose powder and its preparation method and application, so as to achieve long-lasting oil-control effect, enhance the makeup retention, while exerting a good moisturizing and skin-nourishing effect, and effectively avoiding the dryness phenomenon after makeup application.

[0006] To achieve the above purpose, the technical solutions adopted by the present invention include:

[0007] In the first aspect, the present invention provides a long-lasting oil-control loose powder, and the long-lasting oil-control loose powder comprises the following components in parts by weight: 20-70 parts of synthetic fluorophlogopite, 0.5-5 parts of silylated silica, 1-6 parts of hydroxyapatite, 0.7-11 parts of emollient, 0.25-4 parts of humectant, 10-50 parts of skin feel regulator, and 5-40 parts of anti-caking agent; the emollient includes at least one of cetylstearyl ethylhexanoate, Limnanthes Alba (MEYER) BRESS. seed oil, and Helianthus Annuus (LINN.) seed oil.

[0008] The present invention provides a pressed powder that can effectively hold makeup and control oil. By mixing and stirring synthetic fluorophlogopite as a carrier with silylated silica, and then adding hydroxyapatite for coating; wherein, the silylated silica has a flaky structure and strong adsorption, and can perfectly connect synthetic fluorophlogopite and hydroxyapatite to achieve the effect of directional oil control; and hydroxyapatite forms a network structure on the surface of synthetic fluorophlogopite, selectively adsorbing the secreted free fatty acids, helping to regulate sebum secretion, and forming a natural mask on the skin surface. This natural mask effect inhibits the excessive sebum secretion by balancing the water-oil state of the skin, thereby reducing makeup problems caused by excessive oil and enhancing the durability of the makeup effect.

[0009] The oil-control pressed powder of the present invention can not only effectively control oil during daily use, but also maintain the natural balance of the skin for a long time, extend the durability of the makeup, improve the use experience, and solve the problems of existing oil-control products with short-lasting effects, easy caking and floating powder.

[0010] Preferably, the makeup-holding and oil-control pressed powder comprises the following components in parts by weight: 40-65 parts of synthetic fluorophlogopite, 0.8-2 parts of silylated silica, 1-3 parts of hydroxyapatite, 1.3-5 parts of emollient, 0.6-2 parts of humectant, 20-40 parts of skin feel regulator, and 10-30 parts of anti-caking agent.

[0011] Preferably, the makeup-holding and oil-control pressed powder comprises the following components in parts by weight: 52.3 parts of synthetic fluorophlogopite, 1 part of silylated silica, 2 parts of hydroxyapatite, 2.4 parts of emollient, 0.9 part of humectant, 30 parts of skin feel regulator, and 10 parts of anti-caking agent.

[0012] In the present invention, within a specific dosage ratio range of synthetic fluorophlogopite, silylated silica and hydroxyapatite, the three can cooperate with each other to maximize their respective advantages and achieve ideal oil control and makeup holding effects. If the proportion of any one of the components deviates, the oil control effect will be unsatisfactory or the makeup holding time will be too short, and the needs of oily skin and people working for a long time cannot be fully met. Therefore, the precise ratio design is the key to the successful improvement of the oil control and makeup holding ability of the present invention.

[0013] Through experimental exploration, it is found that when synthetic fluorophlogopite, silylated silica and hydroxyapatite are combined with the remaining components in the above optimal dosages, the prepared pressed powder can effectively balance the water-oil state of the skin, and can maintain the stability of the makeup during long-term use, and exert the best oil control and makeup holding effects.

[0014] Preferably, the emollient is cetylstearyl ethylhexanoate, Limnanthes Alba (Meadowfoam) Seed Oil and Helianthus Annuus (Sunflower) Seed Oil, and the mass ratio of cetylstearyl ethylhexanoate, Limnanthes Alba (Meadowfoam) Seed Oil and Helianthus Annuus (Sunflower) Seed Oil is (0.5-5):(0.1-3):(0.1-3).

[0015] The present invention prepares an oil-control loose powder by adding plant-derived emollient raw materials such as Limnanthes Alba seed oil and sunflower seed oil and combining them with cetearyl ethylhexanoate. Among them, Limnanthes Alba seed oil and sunflower seed oil are rich in various plant fatty acids and natural nutrients, which can provide long-lasting moisturizing effects for the skin and avoid uneven makeup or peeling caused by excessive sebum secretion or overly dry skin; cetearyl ethylhexanoate can reduce the oil-absorbing effect of silica, protect the skin from moisture loss, avoid dryness after makeup application, and enhance the moisturizing degree and fit of the product.

[0016] Through experimental exploration, it is found that when the three components are compounded within the above specific ratio range, they can exert an ideal synergistic effect, not only effectively preventing dryness and tightness of the skin during long-term use, maintaining the original moisturizing moisture of the skin, but also optimizing the oil-control performance of the loose powder product, avoiding caking or makeup smudging caused by excessive facial oil, and further improving the makeup retention effect of the product.

[0017] Preferably, the mass ratio of cetearyl ethylhexanoate, Limnanthes Alba seed oil and sunflower seed oil is (1 - 3):(0.2 - 1):(0.1 - 1).

[0018] More preferably, the mass ratio of cetearyl ethylhexanoate, Limnanthes Alba seed oil and sunflower seed oil is 2:0.2:0.2.

In addition, the addition of sericin can also increase the smoothness of the loose powder, make the makeup more fitting, and thus improve the overall effect.

[0022] Preferably, the mass ratio of amino acids, ethylhexylglycerin and sericin is (0.3 - 1):(0.2 - 0.5):(0.1 - 0.5).

[0023] More preferably, the mass ratio of the amino acid, ethylhexylglycerin and sericin is 0.5:0.3:0.1.

[0024] Preferably, the skin feel regulator includes silica / polymethylsiloxane; and / or, the anti-caking agent includes starch octenyl succinate aluminum.

[0042]

[0043]

[0044] Comparative Example 1

[0045] This comparative example provides a long-lasting oil-control loose powder, and the difference from Example 1 is only that: the silylated silica component is missing, and the weight part of synthetic fluorophlogopite is adjusted to 53.3 parts to keep the total weight part unchanged, and the other components and contents are the same as those in Example 1.

[0046] Comparative Example 2

[0047] This comparative example provides a long-lasting oil-control loose powder, and the difference from Example 1 is only that: the hydroxyapatite component is missing, and the weight part of synthetic fluorophlogopite is adjusted to 54.3 parts to keep the total weight part unchanged, and the other components and contents are the same as those in Example 1.

[0048] Effect Example 1

[0049] The long-lasting oil-control loose powder described in Examples 1-10 and Comparative Examples 1-2 was used as the test sample, and its oil-control effect and skin feel were detected and evaluated. The specific method is as follows:

[0050] Select 120 female volunteers with neutral skin, no history of allergies, and healthy skin, aged between 20 and 35 years old. Divide them into 12 groups, with 10 people in each group, and test the samples described in Examples 1-10 and Comparative Examples 1-2 respectively. After the volunteers washed their faces with clean water, they carried out basic skin care using the same skin care products and according to the same process, and then put on makeup according to the same makeup process. Finally, the test sample was used for setting makeup. When the makeup setting was completed, after 4 hours and 8 hours of wearing makeup, a skin oil tester was used to detect the forehead area of the volunteers, and the oil content was recorded. The oil increase rate after 4 hours and 8 hours of wearing makeup was calculated respectively. The oil increase rate = (oil content 持妆4h或8h - oil content 完成定妆时 ) / oil content 完成定妆时 . The average value of each group of data was taken, and the specific results are shown in Table 2.

[0051] In addition, the volunteers scored and evaluated the skin feel of the test samples. The evaluation items included refreshing and moisturizing degree, fit degree, greasiness degree, and light makeup feeling. The scores were between 1 and 10 points. The higher the score, the better the skin feel of the test sample. The average value of each group of scores was taken, and the specific results are shown in Table 3.

[0052] Table 2

[0053]

[0054] Table 3

[0055]

[0056]

[0057] It can be seen from the results of Tables 2-3 that the long-lasting oil-control loose powder described in the present invention has a good oil-control effect, can effectively inhibit the secretion of oil within 8 hours of wearing makeup, and achieve a long-lasting oil-control effect. Moreover, the loose powder has a better evaluation in terms of refreshing and moisturizing degree, fit degree, etc. In particular, the loose powder described in Example 1 has the best effect in terms of oil control and makeup holding, and skin feel. When only cetyl stearyl ethylhexanoate, Limnanthes Alba (MEadowfoam) Seed Oil or Helianthus Annuus (Sunflower) Seed Oil was used as the emollient and combined with the remaining components in Examples 6-8 respectively, the oil-control and skin feel effects of the loose powder decreased to a large extent compared with Example 1, indicating that the use of the above three components in combination can synergistically improve the oil-control effect of the loose powder and achieve a full balance between long-lasting oil control and refreshing and moisturizing effects, thereby effectively improving the user experience. When the components of silylated silica or hydroxyapatite were missing in Comparative Examples 1-2 respectively, the oil-control effect of the prepared loose powder was significantly lower than that of the examples, and the durability of the makeup effect could not be achieved.
