Description

Technical Field

[0001] The present application relates to the technical field of cosmetics, and in particular to a combined fiber for a facial mask cloth, a facial mask cloth and a preparation method thereof, and a facial mask. Background Art

[0002] In recent years, natural plant extracts have been increasingly used in the cosmetics field, such as patch masks. Usually, a patch mask consists of a mask cloth and an essence. The function of the mask cloth is relatively simple, mainly used as a medium carrier to absorb the essence, and generally does not have skin care effects. It should have good mechanical properties, softness, adhesion, water absorption, transparency and other properties.

[0003] As the effective part of the sheet mask, the essence can contain various natural plant extracts and other ingredients to achieve skin care effects such as moisturizing, repairing, and anti-aging. However, the ingredients of natural plant extracts are not pure, and they often introduce a variety of impurities into the essence, which can easily irritate the skin.

[0004] Currently, the mainstream facial mask cloth materials on the market are plant-derived regenerated cellulose fibers such as lyocell fiber or viscose fiber. Functional ingredients such as natural plant extracts are rarely introduced into facial mask cloth materials. At the same time, the relevant performance of facial mask cloths needs to be improved to enhance consumers' usage experience. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present application is to provide a combined fiber for a facial mask cloth, a facial mask cloth and a preparation method thereof, and a facial mask.

[0007] In a first aspect, the present application provides a composite fiber for a facial mask cloth, wherein a Centella asiatica extract and an olive oil extract are introduced into a viscose fiber.

[0008] Centella asiatica, whose Chinese name is "fiber vine", is a plant with great practical value. It can be used for medicine and health care. It is rich in nutrients and active ingredients. It can be used to treat various diseases and help people stay healthy. It can be used in cosmetics to tighten the skin, inhibit edema, and have anti-allergic and repair effects.

[0009] Olive oil, according to the data of the International Olive Oil Council (IOOC), can promote blood circulation, improve digestive system function, enhance endocrine system function, prevent cancer, radiation, anti-aging, prevent cardiovascular and cerebrovascular diseases, etc. It is rich in squalene and essential fatty acids with excellent affinity to the skin, and is quickly absorbed, which can effectively maintain skin elasticity and moisture. The rich monounsaturated fatty acids and vitamins E, K, A, D, etc. and phenolic antioxidants contained in olive oil can eliminate facial wrinkles, prevent skin aging, and have the effects of skin care, hair care, and prevention and treatment of chapped hands and feet.

[0055] Membrane cloth performance test

[0056] (1) Softness test: Refer to GB / T18318.1-2009 Part 1 inclined plane method to test the softness of the membrane cloth.

[0057] (2) Water absorption test: Refer to GB / T24218.6 to test the water absorption of the membrane cloth.

[0058] (3) Transparency test: After a single layer of film is wetted with water, it is covered on a standard text card, and the transparency of the film is judged by comparing it with the standard text color card. The transparency of the standard text color card is divided into 10 levels from 90% to 0%. The number that is close to the appearance after covering the wet film is the transparency rating. The larger the number, the better the transparency.

[0059] (4) Adhesion test: Cut the membrane into 100cm 2 A disc was wetted with water and attached to the back of the test subject's hand. The test subject made a fist and then opened his palm to observe the wrinkles of the membrane. The smaller and denser the wrinkles, the better the adhesion.

[0060] (5) Dimensional stability test: Soak the cut membrane cloth in a standard essence solution (by mass fraction, including 0.5% p-hydroxyacetophenone, 0.5% 1,2-hexanediol, 5% glycerol, 0.2% hydroxyethyl cellulose, 0.1% dipotassium glycyrrhizinate, 0.5% niacinamide, 0.1% sodium hyaluronate, and the balance is deionized water) for a target time, spread it flat on a table, and test the size after soaking in the essence solution, and compare it with the size of the eye holes of the membrane cloth and the initial dry cloth size. If the difference between the initial size and the size after soaking is within 2%, it is excellent, 2% to 5% is good, and more than 5% is fair.

[0061] (6) Tensile index: Refer to GBT24218.3 to test the longitudinal and transverse breaking strength and breaking elongation of the dry film cloth.

[0062] Table 1 Membrane cloth performance test results

[0063]

[0064] According to Table 1, the membrane cloths of Examples 1 to 3 of the present application have good breaking strength and breaking elongation in a dry state, meeting the application requirements. The tearing and pulling actions of the user during the use of the mask will not cause it to break or deform, and can maintain the integrity of the mask, which is beneficial to the durability, fit and use effect of the mask. At the same time, the membrane cloths of the embodiments of the present application have very good softness, excellent water absorption performance, high transparency, good fit and dimensional stability, and can better meet the use requirements of the mask. In particular, comparing Example 1 with Examples 2 to 3, it can be seen that when the viscose fiber containing Centella asiatica extract is 30 parts, the viscose fiber containing olive oil extract is 30 parts, and the lyocell fiber is 40 parts, the comprehensive performance of the obtained membrane cloth is the best.

[0065] According to the comparison results of Example 1 and Comparative Example 1, when the viscose fiber containing the Centella asiatica extract is added, not only the Centella asiatica functional ingredient with soothing effect is introduced into the mask cloth, but also the softness, water absorption rate, and conformability of the mask cloth are unexpectedly significantly improved, and the comprehensive mechanical properties are also improved. In addition, according to the comparison results of Example 2 and Comparative Example 2, when the viscose fiber containing the olive oil extract is added, not only the olive oil functional ingredient with anti-aging effect is introduced, but also the transparency of the mask cloth is unexpectedly significantly improved. Although the water absorption rate, dimensional stability and breaking strength are reduced, they still meet the application requirements.

[0066] Safety Testing

[0067] The membrane fabrics prepared in Examples 1 to 3 were subjected to safety tests, and the test results are shown in Table 2. The test results confirm that the membrane fabrics in the examples of the present application are safe and non-irritating.
