Description

Technical Field

[0001] The present invention belongs to the field of cosmetics, and in particular relates to a whitening and freckle-removing liquid and a preparation method thereof. Background Art

[0002] Freckles, chloasma, age spots, etc. are common skin phenomena in which a large amount of melanin is deposited and distributed unevenly in the human body. Studies have shown that women will produce a large amount of melanin after the age of 25, which brings great psychological pressure to people. The formation mechanism of skin spots is complicated, and the main causes are divided into external factors and internal factors. External factors mainly include excessive ultraviolet radiation, improper maintenance such as the use of inferior cosmetics, and chemical corrosion; internal factors mainly include: chronic liver and gastrointestinal diseases leading to endocrine disorders, genetics, pigment metabolism disorders, aging, etc. The main methods to solve the problem of spots are: removing free oxygen radicals in the skin and body, inhibiting the activity of tyrosinase, and regulating the body's endocrine system and material metabolism. There are many whitening and spot removal products on the market. The main active ingredients they contain are: hydroquinone and its derivatives (arbutin), mercury compounds (hydroquinone), vitamin C, vitamin A and its derivatives kojic acid, etc. These products have the following problems: (1) They are only effective for certain spots, and the spot removal is not comprehensive and the effect is slow. (2) The spot removal is not thorough and is prone to recurrence. (3) Mercury-containing cosmetics can irritate and damage the skin and may even cause poisoning. Summary of the Invention

[0003] The purpose of the present invention is to provide a whitening and freckle-removing liquid to solve the defects of existing whitening and freckle-removing products.

[0004] The technical solution adopted in the present invention is as follows: A whitening and freckle-removing liquid is prepared by soaking the following raw materials in parts by weight: 22-32 parts of radix scutellariae root, 22-32 parts of angelica dahurica, 4-6 parts of peach gum, 18-22 parts of juniper flower, 12-14 parts of phellodendron amurense, 12-14 parts of sodium sulfate, 18-22 parts of motherwort, 98-102 parts of persimmon leaf, 12-14 parts of artemisia annua, 0.18-0.22 parts of vitamin C, 4.5-5.5 parts of lanolin, 9-11 parts of mulberry root, and 2495-2505 parts of alcohol.

[0005] Furthermore, the whitening and freckle-removing liquid is prepared by soaking the following raw material components in parts by weight: Root of the Chinese angelica 30, Angelica dahurica 30, Peach Gum 5, Sabina Flower 20, Phellodendron amurense 13, Sodium Sulfate 13, Motherwort 20, Persimmon Leaf 100, Artemisia Annua 13, Vitamin C 0.2, Lanolin 5, Morus Alba 10, Alcohol 2500.

[0006] Furthermore, the whitening and freckle-removing liquid is prepared by soaking the following raw material components in parts by weight: 22 parts of radix ophiopogonis root, 22 parts of angelica dahurica, 4 parts of peach gum, 18 parts of juniper flower, 12 parts of phellodendron amurense, 12 parts of sodium sulfate, 18 parts of motherwort, 98 parts of persimmon leaf, 12 parts of artemisia annua, 0.18 parts of vitamin C, 4.5 parts of lanolin, 9 parts of mulberry, and 2495 parts of alcohol.

[0007] Furthermore, the whitening and freckle-removing liquid is prepared by soaking the following raw material components in parts by weight: 32 parts of radix scutellariae root, 32 parts of angelica dahurica, 6 parts of peach gum, 22 parts of juniper flower, 14 parts of phellodendron amurense, 14 parts of sodium sulfate, 22 parts of motherwort, 102 parts of persimmon leaf, 14 parts of artemisia annua, 0.22 parts of vitamin C, 5.5 parts of lanolin, 11 parts of mulberry, and 2505 parts of alcohol.

[0008] Furthermore, the preparation method of the whitening and freckle-removing liquid comprises the following steps: (1) Weigh the raw materials of each component according to the formula ratio; (2) Put the weighed raw materials into a container, pour the weighed alcohol into the container, seal it and soak it for a certain period of time; (3) When the soaking time reaches the required time, the soaking liquid is filtered and the filtrate is collected to obtain the finished whitening and freckle removal liquid.

[0009] Furthermore, the alcohol has a mass percent concentration of 75%.

[0010] Furthermore, when the raw material components are soaked with alcohol in step (2), the total mass / volume ratio of the raw material components to the alcohol is g / ml: 10:95-105.

[0011] Furthermore, when the raw material components are soaked in alcohol in step (2), the soaking time is 55-65 days.

[0012] Furthermore, when the raw material components are soaked in alcohol in step (2), the soaking time is 60 days.

[0013] A proper amount of essential oil is also added to the whitening and freckle-removing liquid.

[0014] The whitening and freckle-removing liquid described herein is a light yellow, translucent liquid with a light, refreshing fragrance and a pH of 5.5-6.0. The product should be stored sealed in a cool, dry environment at 15-25°C, away from direct sunlight. The whitening and freckle-removing liquid can be diluted and applied directly to the affected area. It can also be formulated into creams, serums, lotions, and the like.

[0015] Research has found that people begin to deposit melanin at the age of 25. In middle and old age, some people have melanin deposits near blood vessels, such as on the back of hands and cheeks, and pigmentation on the limbs. There are individual differences in pigmentation. Some people have fewer spots in old age, while others have more. The reason is that different people have different metabolisms. Some have weak metabolism and cannot metabolize and excrete melanin. The formula is in line with the body's weak metabolism, which allows melanin to be excreted as soon as possible, and some spots become scabs and melanin is eliminated.

[0016] The whitening and freckle-removing liquid formulated with the present invention contains various bioactive substances, such as flavonoids, polyphenols, and volatile oils. These substances may have antioxidant and anti-inflammatory effects, as well as inhibit tyrosinase activity. Tyrosinase is a key enzyme in melanin synthesis, and inhibiting its activity can reduce melanin production, thereby achieving a whitening effect. Furthermore, these plant ingredients may promote skin metabolism and accelerate the shedding of the aging stratum corneum, resulting in smoother and more delicate skin.

[0017] Motherwort: Motherwort has the effect of promoting blood circulation and removing blood stasis, and also has the effect of tightening the skin.

[0018] Peach gum: Peach gum is rich in polysaccharides, which have a certain moisturizing effect, help to maintain skin moisture, improve skin dryness, peach gum also has a skin softening effect, indirectly promotes skin health, and has an auxiliary effect on whitening and freckle removal.

[0019] Juniper flower: contains volatile oils, flavonoids and other ingredients, which have antioxidant and anti-inflammatory effects, help reduce skin inflammation, improve skin condition, and assist in whitening and removing spots.

[0020] Phellodendron amurense: Phellodendron amurense contains a variety of alkaloids, which have antibacterial and anti-inflammatory effects, helping to reduce skin inflammation and improve pigmentation caused by inflammation.

[0021] Artemisia annua has anti-inflammatory and antioxidant properties that help improve uneven skin tone, prevent the formation of dark spots, and has mild whitening potential.

[0022] Mulberries: Mulberries have high antioxidant capacity, can neutralize free radicals, reduce melanocyte activation, and have mild whitening potential.

[0023] Glauber's Salt: Its main ingredient is sodium sulfate. When applied topically, it has astringent and anti-inflammatory properties, alleviating skin inflammation and indirectly promoting whitening and freckle removal by improving the skin's environment. Vitamin C: Vitamin C is a powerful antioxidant that inhibits tyrosinase activity and reduces melanin synthesis, thus directly contributing to skin whitening. It also promotes collagen synthesis, helping to maintain skin elasticity and radiance.

[0024] Lanolin: Lanolin has good moisturizing and nourishing effects. It can form a protective film to prevent skin moisture loss, keep the skin moisturized, help improve dry and rough skin, and indirectly promote whitening, freckle removal and moisturizing effects.

[0025] Alcohol: Alcohol may be used as a solvent in a formula to help other ingredients dissolve and penetrate the skin better.

[0026] In short, this whitening and freckle removal liquid achieves multiple functions such as inhibiting melanin production, promoting skin metabolism, moisturizing and nourishing through the synergistic effect of various plant ingredients, vitamin C, lanolin and other raw materials, thereby achieving the effect of whitening and freckle removal. It is easy to use, has obvious freckle removal, and has no adverse reactions with long-term use.

[0027] Product Trial Instructions 1. Whitening trial: There are 20 trial participants, aged between 35 and 55 years old, with occupations including 6 bank clerks, 4 teachers, 5 workshop workers, and 5 insurance salesmen. The trial period is 21 days. During the trial period, the product is applied on the hands and face every day, once in the morning and once in the evening. After one week of trial, the skin color has improved. With continued use, the skin color becomes whiter and whiter. After 21 days of use, the skin has been significantly improved without any adverse reactions. After stopping application for half a year, the skin color has remained good.

[0028] Second, freckle removal trial: 10 people applied the product on their hands and faces (ages 35 to 55 years old); occupations: waiters, office workers, and factory workers. Six people's freckles were basically gone in 30 days, seven people's chloasma disappeared in 30 days, and eight people's freckles disappeared in 30 days, with no adverse reactions. Some people developed scabs on the freckles, and some had obvious irritation during use, but the rest of the skin did not feel irritation. 3. 10 people tested the product on their hands and faces (ages 35 to 55 years old); occupations: waiter, sanitation worker, factory worker. The results of the trial showed noticeable improvements in their skin immediately after use. 1. Changes in the stratum corneum; 2. Softening and finesse of the skin surface; 3. Unsatisfactory skin moisturization.

[0029] 4. After applying it on the hands and face, the product dissolves into the stratum corneum and the skin returns to its original state. After 12 hours of discontinuation of use, the skin returns to its original state.

[0030] 5. The trial period of 30-384 days after application on hands and face showed no adverse reactions, indicating that the product is safe and stable.

[0031] Additional explanation: The human body has the ability to metabolize melanin, but as the body ages, it cannot metabolize all the melanin. Chinese herbal cosmetics accelerate the metabolism of melanin and excrete it out of the body. Trial users have found this product to be safe and effective. DETAILED DESCRIPTION
