Description

Technical Field

[0001] The present invention relates to the field of cosmetics, and particularly to a loofah water-based lip gloss and a preparation method thereof. Background Art

[0002] Lip gloss is a kind of liquid lipstick. The colorant in traditional lip gloss is usually dissolved in oil and adhered to the lips to play a decorative role. When the lips come into contact with food or containers such as water cups, bowls, etc., the colorant will also adhere to these containers together with the oil, or dissolve in the saliva in the mouth. Therefore, traditional lip gloss is prone to problems such as color printing and color fading, i.e., the color does not last long, when drinking water or speaking. In addition, traditional oily lip gloss and lip balm have the disadvantages of greasiness and difficulty in removing makeup as the colorant gets into lip wrinkles.

[0003] Loofah extract is an active ingredient extracted from the fresh fruits of the cucurbitaceous plants loofah or Luffa acutangula. It contains rich nutrients such as triterpenoid saponins (loofah glycosides), proteins, carbohydrates, carotenoids, vitamins, and various trace elements. These components make it a popular beauty and skin care raw material with excellent moisturizing effects. At present, it is rarely added to lip gloss. Therefore, the present invention provides a method for preparing water-based lip gloss using loofah. Summary of the Invention

[0004] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art, and to provide a loofah water-based lip gloss and a preparation method thereof.

[0005] The technical solution of the present invention is as follows:

[0006] A preparation method of a loofah water-based lip gloss, comprising the following steps:

[0007] S1: Dry the loofah, crush it, extract with an extraction solvent, filter, and concentrate under reduced pressure to obtain a loofah extract;

[0008] S2: Mix 5 - 10 parts of loofah extract, 0.1 - 3 parts of colorant, 10 - 20 parts of modified waterborne polyurethane, 1 - 3 parts of hyaluronic acid, 10 - 20 parts of oil ester, and 0.1 - 0.5 part of emulsifier evenly to obtain the product.

[0009] As a preferred embodiment of the present invention, in step S1, the extraction solvent is a plant enzyme and ethanol with a mass ratio of 1 - 3:1.

[0010] As a preferred embodiment of the present invention, the preparation method of the plant enzyme: Crush the frozen tea leaves and aloe vera, add them to a mixed solution of sodium carbonate and sodium bicarbonate for ultrasonic extraction, centrifuge to take the supernatant, concentrate, and freeze-dry to obtain it.

[0011] As a preferred embodiment of the present invention, the mass ratio of the tea leaves to the aloe vera is 1 - 5:2 - 3.

[0012] As a preferred embodiment of the present invention, the mass ratio of sodium carbonate to sodium bicarbonate is 1:1 - 2.

[0013] As a preferred embodiment of the present invention, the crushing speed is 2000 - 3000 rpm, and the crushing time is 40 - 80 s.

[0014] As a preferred embodiment of the present invention, the time for ultrasonic extraction is 10 - 30 min.

[0015] As a preferred embodiment of the present invention, the preparation method of the modified aqueous polyurethane:

[0016] Add papain to the chitosan acetate solution, stir and homogenize in an ice bath at 0 - 6 °C, and then add aqueous polyurethane and heat to 30 - 50 °C to mix evenly.

[0017] As a preferred embodiment of the present invention, the emulsifier is polyglyceryl-2 diisostearate; the colorant is a mixture of bromophenol red dyes and butyl stearate;

[0018] The oil includes at least one of beeswax, castor oil, squalane, and jojoba oil.

[0019] A loofah aqueous lip gloss is prepared by using the preparation method described in any one of the above.

[0020] The beneficial effects of the present invention are:

[0021] By adding loofah extract, the present invention can greatly improve the moisture retention of the lip gloss. In addition, a mixed solution of plant enzyme and ethanol is used as the extractant. Due to the strong autocatalytic ability of the plant enzyme and the cell wall breaking effect of ethanol, the dissolution rate of loofah active substances is improved. Moreover, by modifying the aqueous polyurethane, papain is combined with the aqueous polyurethane in the form of chitosan wrapping. When applied, the friction between the lips causes the papain to dissolve, which can decompose the aging proteins on the surface of the lip skin, and combined with the loofah active substances, it promotes the adsorption ability of the lip skin, making the lip gloss more durable and not easily smudging.

[0098] Comparative Example 3

[0099] Different from Example 2, the aqueous polyurethane was not modified.

[0100] The performances of the above examples and comparative examples were tested, and the test results are shown in Table 1.

[0101] Test samples: Samples of the examples and comparative examples were selected.

[0102] Test method: 80 subjects aged 20 - 25 with healthy lip skin in the same area were selected and evenly divided into 8 groups.

[0103] The lips of the subjects in each group were cleaned with the same type of facial cleanser (no discomfort occurred to the subjects), and after natural air drying, the lip skin moisture content data of the subjects in each group were measured, which was X1; then the corresponding subjects were asked to apply the corresponding test samples, with the usage amount of 0.2 mL per person. After application, after 3 h, the test samples applied to the lips were gently wiped clean with the same type of cosmetics, and then the lip skin moisture content of each group of subjects was measured again, which was X2. Calculate the average change in lip skin moisture content of each group of subjects before and after applying the test samples for 3 h (first calculate X2 - X1, and then perform average processing for each group). At the same time, record the persistence of the lips for 3 h.

[0104] Table 1 Performance test results of examples and comparative examples

[0105] Specimen Change rate of lip moisture content (%) Persistency (sensory evaluation) Example 1 +5.23 Very excellent Example 2 +5.26 Very excellent Example 3 +5.12 Very excellent Example 4 +5.21 Very excellent Example 5 +5.19 Very excellent Comparative Example 1 +3.89 Good Comparative Example 2 +1.89 Poor Comparative Example 3 +3.11 Average

[0106] As can be seen from the above table, the performance of the examples is better than that of the comparative examples, and the main reasons are as follows; from the analysis of Comparative Example 1, a mixed solution of plant enzyme and ethanol was used as the extractant. Due to the strong autocatalytic ability of the plant enzyme and the cell wall breaking effect of ethanol, the dissolution rate of the active substances in loofah was increased; from the analysis of Comparative Example 2, by adding the loofah extract, the moisture retention of the lip gloss could be greatly improved; from the analysis of Comparative Example 3, by modifying the aqueous polyurethane, papain was combined with the aqueous polyurethane in the form of chitosan wrapping. During application, the friction between the lips caused the papain to dissolve out, which could decompose the aged proteins on the surface of the lip skin, and combined with the active substances in loofah to promote the adsorption ability of the lip skin, making the lip gloss more persistent.

[0107] The above-described embodiments merely represent the preferred embodiments of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, based on the technical solutions and concepts described above, various other corresponding changes and deformations can be made, and all such changes and deformations should fall within the protection scope of the claims of the present invention.
