Abstract
Description
Technical Field
[0001] This invention belongs to the field of cosmetic technology, specifically relating to a whitening and repairing composition, cosmetic, and its preparation method. Background Technology
[0002] In the cosmetics field, the development of multifunctional active compositions that simultaneously possess whitening, barrier repair, long-lasting moisturizing, and high-efficiency antioxidant properties is a current research hotspot. However, existing composite formulations of this type still face the following key technical bottlenecks: (1) The four needs of whitening, repairing, moisturizing, and anti-oxidation are usually separated into independent product lines, resulting in fragmented effects. Consumers need to use them in combination, increasing the risk of skin irritation and the cost of use; (2) When high concentrations of vitamin C, polyphenols, and plant extracts coexist, oxidation, discoloration, precipitation, or pH drift can easily occur, leading to product stability issues; (3) Single high-concentration active ingredients (such as niacinamide ≥5%, kojic acid ≥2%) are highly irritating and can easily cause stinging, redness, and further damage to the skin barrier; (4) Existing compositions do not fully consider the interactions between active ingredients. For example, polyphenols and niacinamide are prone to forming complexes at low pH, leading to loss of activity.
[0003] Chinese patent CN116473899A discloses a whitening composition with long-lasting repair effects, its preparation method and application, including creatinine, 20-50 parts; azelaic acid MEA, 5-20 parts; plant extract containing acetylated polysaccharides, 1-10 parts; whitening agent, 10-30 parts; buffer, 10-30 parts. Although it has moisturizing, repairing and anti-inflammatory effects, it contains a large amount of whitening agents such as nicotinamide and its derivatives, vitamin C and its derivatives, ferulic acid and its derivatives, and tranexamic acid, which can easily cause the system to be unstable.
[0004] Therefore, there is an urgent need in the field for a composition that can simultaneously achieve multiple effects such as whitening, repairing, moisturizing, and anti-oxidation at a mild and safe concentration, and has long-term stability, for use as a cosmetic ingredient. Summary of the Invention
[0005] To address the shortcomings of the prior art, this invention provides a synergistic composition that simultaneously contains whitening, repairing, moisturizing, and antioxidant active ingredients. By combining these ingredients in specific proportions, the invention maximizes efficacy and stability. Based on this, the invention provides the following technical solution:

[0019] Furthermore, the moisturizer includes at least one of trehalose, betaine, glycerin, sodium hyaluronate, and panthenol. In one embodiment, the mass ratio of trehalose, betaine, glycerin, sodium hyaluronate, and panthenol is 1-2:1-2:3-6:0.01-0.1:1.

[0036] The beneficial effects of this invention are:
[0037] The composition of this invention contains a high content of proanthocyanidins in the coastal pine bark extract, which can effectively inhibit tyrosinase activity and block upstream signals for melanin synthesis. The rosewood extract has a structure similar to resveratrol but is more lipophilic, allowing it to penetrate deep into the basal layer, inhibiting the transport of melanosomes to keratinocytes and reducing pigmentation and dullness. The scutellaria root extract is rich in baicalin, which can inhibit post-inflammatory hyperpigmentation caused by inflammatory factors, scavenge various free radicals such as ·OH and O2·-, and block photoaging cascades. The centella asiatica leaf extract can accelerate the repair of damaged stratum corneum and reduce transepidermal water loss. The yeast fermentation product is rich in polypeptides, B vitamins, and natural moisturizing factors, strengthening intercellular lipids and restoring the skin's brick-and-wall structure. The composition of this application achieves a synergistic effect of "whitening-repairing-moisturizing-antioxidant" in a single system. All ingredients are natural or of equivalent natural origin, are mild and non-irritating, and through ingredient compatibility, excellent composition stability can be achieved, making it suitable for use as a raw material in various cosmetic formulations.

[0114] Performance testing methods and results:
[0115] I. Tyrosinase Inhibition Rate Test:
[0116] (1) Experimental reagents:
[0117] PBS buffer with a pH of 6.8;
[0118] 100 U / mL tyrosinase solution (prepared with PBS buffer);
[0119] 1 mg / mL levodopa solution (prepared with PBS buffer).
[0120] Enzyme solution blank control group-A: 1.5 mL PBS buffer;
[0121] Enzyme solution control group-B: 0.5 mL tyrosinase solution + 1.0 mL PBS buffer.
[0122] Sample blank control group-C: 0.5 mL PBS buffer + 1 mL of the composition of the example.
[0123] Sample group-D: 0.5 mL tyrosinase solution + 1 mL of the composition of the example.
[0124] (2) Experimental steps: Place the test tubes of each group in a water bath at 37℃ for 10 min; add 2 mL of levodopa solution to the centrifuge tubes after incubation, incubate at 37℃ for 5 min, and measure the absorbance value (OD) at 475 nm using an ELISA reader to calculate the tyrosinase inhibition rate.
[0125] The formula for calculating the tyrosinase inhibition rate is as follows:
[0126] Tyrosinase inhibition rate (%) = 1 - [(OD D -OD C ) / (OD B -OD A )]×100%;
[0127] (3) The calculation shows that the composition of Example 1 of this application has an inhibition rate of >80% against tyrosinase, which proves that the composition of this application has a good whitening effect.
[0128] II. Transepidermal moisture loss rate test:
[0129] (1) Sample and control areas were set up on the skin of the inner forearm of the subject. The area of each sample and control area was 3cm*3cm, and the area was 1cm apart. After the subject's exposed arm skin rested for 20 minutes in a constant temperature and humidity chamber (temperature 20℃±1℃, humidity 50%±10%), 3M tape of the same specification (viscosity about 3N) was applied to the test area. The tape was rolled back and forth 3 times on the surface of the tape using an 80g roller. After 30s, the tape was torn off at a tearing rate of 30cm / s. The tape application-tearing step was repeated 10 times to establish a skin model for testing.
[0130] (2) The cosmetic samples of the examples and comparative examples were applied to the sample area on the inner forearm of the arm and left to stand for 1 hour under experimental conditions; the transepidermal water loss rate of the skin was measured using a TEWL Tewameter. The experimental results are shown in Table 6.
[0131] Table 6
[0132]
[0133] According to Table 6, the compositions and cosmetics of the embodiments of this application have good performance in inhibiting transepidermal water loss, proving that they have good repair effects.
[0134] III. Stability Testing:
[0135] 1. High and low temperature stability: The compositions and cosmetics of the examples and comparative examples were stored at room temperature, 45°C, and -15°C for 3 months, respectively. They were then removed on days 7, 14, 21, 30, 60, and 90.
[0136] After the sample is brought back to room temperature, observe its color and appearance, as well as whether the solution has any defects such as fading, layering, or precipitation.
[0137] 2. Cyclic stability: A two-day hot and cold cycle is used as one cycle. The solution is placed in a -15℃ constant temperature chamber on the first day and in a 45℃ constant temperature chamber on the second day. After 30 consecutive days of testing, the solution is removed and its appearance is observed after it returns to room temperature.
[0138] The performance test results are shown in Table 7.
