Description

Technical Field

[0001] The present invention belongs to the technical field of cosmetics, and particularly relates to a freckle-removing cream pen with yellow peel essential oil and a preparation method thereof. Background Art

[0002] Tyrosinase is an important rate-limiting enzyme in the reaction of generating melanin, and is widely distributed in microorganisms, animals, plants and the human body. The large accumulation of melanin in the human body will cause diseases such as pigment spots and malignant melanoma. In addition, the overexpression of tyrosinase will cause enzymatic browning during the processing and sales of fruits and vegetables, thus affecting the appearance, flavor and nutritional value of fruits and vegetables. Therefore, reducing the activity of tyrosinase can achieve the effects of fading freckles and preserving fruits and vegetables. However, many tyrosinase inhibitors reported in recent years are not very ideal in terms of safety and practicability. Therefore, relatively safe natural extracts have become the research direction for developing new tyrosinase inhibitors.

[0003] The existing freckle-removing pens are usually pen-shaped and equipped with a silicone brush head for convenient dipping and application. However, for users who need a large amount of use, they need to dip multiple times, and the essence at the bottom may not be easily taken out completely, with small capacity and inconvenient use. At the same time, directly applying the brush head to the face is likely to cause pollution. Some ingredients of the freckle-removing pen (such as alcohol) may cause irritation to the skin. For example, when used around the eyes, it may cause a stinging feeling in the eyes, and people with sensitive skin may have an allergic reaction after use. In addition, the existing freckle-removing pens may have a shelf life limit. For example, the shelf life is only about one year. In contrast, the essential oil freckle-removing cream can avoid the disadvantages of inconvenient use, small capacity, skin irritation and short shelf life. However, the existing essential oil freckle-removing creams usually contain plant essential oils such as carrot seed essential oil and Damascus rose essential oil, which have certain antioxidant, repair and whitening effects on the skin. However, carrot seed essential oil has the defect of photosensitivity, and Damascus rose is expensive and not easily available, resulting in a high price for existing freckle-removing cream products. Therefore, it is necessary to develop a new type of freckle-removing cream with low raw material prices and easy availability to avoid the disadvantages of inconvenient use, small capacity, skin irritation and short shelf life in the prior art. Summary of the Invention

[0004] In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a plant essential oil freckle-removing cream pen that is beneficial to inhibiting the generation of melanin. The raw materials of the essential oil cream pen include beeswax, olive oil, honey, vitamin E and a compound essential oil, wherein the compound essential oil is mainly yellow peel essential oil, supplemented by parsley seed essential oil and neroli essential oil. The present invention first uses the essential oil cream pen for freckle removal, which not only has the effects of whitening and freckle removal, inhibiting melanin deposition, etc., but also has the advantages of convenient use and carrying. In addition, the raw materials are low in price and easy to obtain, overcoming the disadvantages of inconvenient use, small capacity, skin irritation and short shelf life.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0008] In the present invention, the inhibitory effects of three volatile oils and their main components on tyrosinase were evaluated through tyrosinase inhibition tests. The results showed that citral, the main component in wampee essential oil, has a certain inhibitory ability on the activities of both monophenolase and diphenolase of tyrosinase, and its inhibitory ability on tyrosinase diphenolase is stronger than that on tyrosinase monophenolase. Wampee essential oil is rich in active substances such as volatile oils and alkaloids. Citral is one of the important components in wampee volatile oil. Citral can bind to tyrosinase and inhibit its activity, thereby reducing the synthesis and deposition of melanin, achieving the effects of whitening and freckle removal. The specific content of citral in wampee may vary slightly due to factors such as the variety, origin and maturity of wampee.

[0025] The following further describes the detailed implementation manners of the present invention. It should be noted here that the descriptions of these implementation manners are for helping to understand the present invention, but do not constitute a limitation to the present invention. In addition, the technical features involved in the various implementation manners of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] The experimental methods in the following examples are all conventional methods unless otherwise specified, and the test materials used in the following examples are all available through conventional commercial channels unless otherwise specified.

[0027] Term explanation:

[0028] The essential oil cream pen is a portable essential oil product. Usually, the essential oil is mixed with wax or oil to form a solid state and filled into a rotating tube similar to a lip balm for convenient application at any time.

[0029] Melanin is a high-molecular biological pigment, which is essentially a kind of protein and usually exists in the form of polymerization in human skin or hair. Skin melanin is formed by a series of chemical reactions from tyrosine or 3,4-dihydroxyphenylalanine (DOPA), etc. The specific process includes that tyrosine is oxidized to dopaquinone under the catalytic action of tyrosinase, and dopaquinone finally generates eumelanin or pheomelanin through a series of reactions.

[0030] Wampee essential oil: Wampee is a fruit commonly found in southern China and Southeast Asia, with a unique aroma and medicinal value. Wampee essential oil is a natural essential oil extracted from the peel, leaves or seeds of wampee (Clausena lansium). The components of wampee essential oil are complex and mainly include the following compounds: (1) Limonene and citral: having a fresh citrus aroma and commonly used in fragrance and cleaning products; (2) γ-Terpinene: having antioxidant and antibacterial properties; (3) α-Pinene: having anti-inflammatory and antibacterial effects; (4) β-Caryophyllene: having anti-inflammatory and analgesic effects. Among them, citral can inhibit the activity of tyrosinase and reduce the generation of melanin, thus helping to whiten the skin and fade skin spots.

[0031] Neroli essential oil: Rich in a variety of whitening active ingredients, it can inhibit the synthesis of melanin in cells and the activity of tyrosinase, and eliminate melanin with the metabolism of aging cutin, making the skin gradually fair.

[0032] Parsley seed essential oil is an essential oil extracted from parsley seeds. It not only contains no photosensitive furanocoumarins, but also is rich in 8 kinds of furan lactones and other whitening skin care ingredients. The furan lactones in parsley seed essential oil are the key ingredients for whitening and fading spots, which can inhibit the activity of tyrosinase in the skin, thus hindering the synthesis of melanin. The phthalide component in parsley seed essential oil can remove the lipofuscin in the body, and lipofuscin is an aggregated waste of peroxidized fat and protein, which will accumulate in the liver and under the skin to form chloasma, and will also deposit in the brain to reduce memory. Therefore, removing lipofuscin helps to purify the blood and liver, reduce the formation of spots, and thus achieve the whitening effect.

[0033] Tyrosinase is a key redox enzyme that exists widely in animals, plants and microorganisms and participates in biological processes such as skin melanin synthesis. Therefore, measuring its activity is an important means for studying enzyme function and inhibitor screening. Since the substrate catalyzed by tyrosinase (such as L-tyrosine or L-DOPA) can generate a colored product (such as dopaquinone), the enzyme activity can be evaluated by measuring the change in absorbance.

[0034] The following is the method for measuring the activity of tyrosinase in each example and comparative example of the present invention:

[0035] (1) Experimental preparation

[0036] Substrate preparation: Using dopa (D,L-3,4-dihydroxyphenylalanine, Sigma) as the substrate. Prepare the substrate solution, and prepare a 0.005 mol / L substrate solution (DOPA solution) with dopa, and the solvent is a sodium phosphate buffer solution with pH = 6.5 and a concentration of 0.05 mol / L. At the same time, prepare a 5 mmol / L dopa solution (prepared with a sodium phosphate buffer solution with 0.05 mol / L and pH 6.5) for subsequent extended experiments.

[0037] (2) Instrument preparation: Use the L6 Internet of Things intelligent ultraviolet-visible spectrophotometer of Youke Company to measure the activity of PPO (polyphenol oxidase) at a wavelength of 475 nm.

[0038] (3) Reaction system setting

[0039] Reaction cell setting: Add 2.98 mL of 0.005 mol / L substrate solution (DOPA solution, prepared in a sodium phosphate buffer solution with pH = 6.5 and a concentration of 0.05 mol / L) to the reaction cell, and 0.02 mL of enzyme solution will be added later.

[0040] Reference cell 1 setup: Add 2.98 mL of the same DOPA solution as in the reaction cell to reference cell 1, and replace the enzyme solution with 0.02 mL of sodium phosphate buffer with pH = 7.2 and 0.05 mol / L.

[0041] Reference cell 2 setup: Add 2.98 mL of sodium phosphate buffer with pH = 6.5 and a concentration of 0.05 mol / L to reference cell 2 to replace the substrate solution in the reaction cell, and then 0.02 mL of enzyme solution will be added later.

[0042] (4) Reaction process operation

[0043] Preheating treatment: Before adding 0.02 mL of enzyme solution, pre-incubate the reaction cell, reference cell 1, and reference cell 2 at 30 °C.

[0044] Start the reaction: Add 0.02 mL of enzyme solution to the reaction cell and reference cell 2, and start timing immediately after adding the enzyme solution.

[0045] Absorbance measurement: Using 0.05 mol / L sodium phosphate buffer with pH = 6.5 as a control, use a UV-visible spectrophotometer to measure the change in absorbance at a wavelength of 475 nm at 30 °C after 2 minutes of reaction. The change in absorbance caused by PPO acting on the substrate is represented by the difference in absorbance between the reaction cell and reference cells 1 and 2 at a wavelength of 475 nm.

[0046] (5) Definition of enzyme activity

[0047] One unit of enzyme activity is defined as: the amount of enzyme required to cause a change in A475nm of 0.001 per minute at 30 °C and pH = 6.5.

[0048] (6) Handling of special situations

[0049] During the measurement, since the substrate and product may be unstable, the reaction conditions need to be strictly controlled.

[0050] (7) Extended experiment

[0051] Add the sample to be tested (such as essential oil) to a 5 mmol / L dopa solution (prepared with 0.05 mol / L sodium phosphate buffer with pH 6.5) to make its concentration reach 0.5%, and the effect of the sample to be tested on the activity of PPO can be further studied.

[0052] Example 1: Inhibitory effect of different plant essential oils on tyrosinase

[0053] First, the inhibitory effects of different essential oils (wampee essential oil, parsley seed essential oil, neroli essential oil, carrot seed essential oil, and rose essential oil) on the relative enzyme activity of tyrosinase were detected according to the tyrosinase enzyme activity assay method. Among them, the wampee essential oil used was obtained by steam distillation from the peel and leaves.

[0054] As can be seen from Figure 1 , the plant essential oils used in the present invention all have a certain inhibitory effect on the activity of tyrosinase. After adding wampee essential oil, parsley seed essential oil, neroli essential oil, carrot seed essential oil and rose essential oil with a concentration of 0.5% to the reaction system respectively, the enzyme activity decreased to 35.5%, 68.1%, 58.5%, 87.9% and 73.6% of the original after 1 day of action.

[0055] Meanwhile, further detect the effect of different concentrations of essential oils on the relative enzyme activity of tyrosinase according to the tyrosinase enzyme activity assay method. As Figure 2 shown, the inhibitory effect of wampee essential oil on the activity of tyrosinase is significant. After adding wampee essential oil with concentrations of 0.2%, 0.25%, 0.5%, 1%, 1.5%, 2%, 2.5%, 3.5%, 8% and 10% to the reaction system respectively, the activity of tyrosinase decreased from the original remaining 73% to 12.3% after 1 day of action.
