Description

Technical Field

[0001] The invention relates to the technical field of daily chemical products, and in particular to a repairing and color protecting composition and a shampoo product and a preparation method thereof. Background Art

[0002] With the rapid development of the economy, consumers' demand for hairdressing is increasing, and the frequency of hair dyeing, straightening, bleaching, and styling is increasing. In addition, ultraviolet rays and environmental pollution can also cause damage to hair, which often leads to problems such as hair scales curling, brittleness, easy breakage, difficulty in combing, and damaged hair. As a sub-area of ​​shampoo products, shampoo products with the function of repairing and protecting color will have broad application prospects.

[0003] The hair dye commonly used in hair dyeing is an oxidative hair dye, which mainly contains two parts: an oxidant and a colorant. The oxidant contains alkaline ingredients, which will cause the hair scales to open when applied to the hair, which allows the dye intermediates and coupling agents to penetrate into the cortex of the hair in the form of small molecules. Under the action of alkali and hydrogen peroxide, relatively large dye molecules are formed and are enclosed inside the hair fibers. Hair dyeing can damage the hair keratin, cause the hair scales to curl up, and make the hair fragile, dry, and easy to break. In addition, with the use of shampoo products, the color of the dyed hair will gradually fade, which is very different from the initial color after dyeing. The perming agents used for perming usually contain thioglycolic acid, etc. These ingredients will destroy the disulfide bonds in the hair structure and change the structure of the hair, thereby achieving a curling effect. The perming process will cause changes in the structure of the hair keratin and lipids, making the hair dry, fragile, and easy to break, and losing the original luster and elasticity of the hair. In addition, light damage is also one of the important factors that cause hair damage. Light damage can cause the breakage of disulfide bonds, lipid oxidation, amino acid and melanin degradation, and ultimately lead to reduced hair strength, fading, hardening and brittleness, and reduced glossiness. Repairing and protecting damaged hair is still one of the top demands of consumers.

[0004] Existing patent CN109431933B discloses a sunscreen and color-protecting hair lotion, which can protect against the sun, dye black, and fix color. Another patent CN109589282B discloses a hair wet wipe liquid with sunscreen and color-protecting functions, which can help reduce hair damage caused by sun exposure and slow down the color fading of dyed hair. Another patent CN116139041A discloses a cationic color-protecting composition, which can protect the color of dyed hair and slow down the fading, and can also condition the hair and repair the hair scales. Another patent CN112933002B discloses a hair care composition with hair color protection function, which can repair the raised hair scales on the surface of the hair, maintain the color of hair of different colors, and has a certain color protection effect on the hair. The above invention patents protect and repair hair color mainly by supplementing the lipids in the hair surface and adding ultraviolet absorbers, repairing the raised hair scales on the hair surface, reducing hair fading caused by light damage, and to a certain extent reducing the pigment loss caused by the raised hair scales. On the other hand, there is little mention of the improvement effect on the scalp barrier.

[0005] The above prior art only involves repairing and protecting the color on the surface of hair, but does not provide effective solutions for the oxidation of the internal structure of hair caused by dyeing and perming, changes in lipid and amino acid composition, chemical bond breakage and their interactions, and improvement of the scalp barrier. Therefore, there is an urgent need to seek a repair and color protection composition and shampoo product and preparation method thereof, which can penetrate from the surface of hair into the interior of hair fibers, help repair the structural integrity of damaged hair, so as to achieve the maximum degree of repair and color protection, while being mild to the scalp and enhancing the effect of the scalp barrier. Summary of the invention

[0006] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a repair and color protection composition, the components of which cooperate with each other to play a synergistic role and have excellent color protection and repair effects.

It has a color protection effect on dyed hair and can improve the scalp barrier. Another object of the present invention is to provide a shampoo product containing the repair and color protection composition and a preparation method thereof. The use of a shampoo product containing the above-mentioned repair and color protection composition can not only reduce the fading of dyed hair, but also have a certain repair effect on hair, and can also improve the scalp barrier.

[0070] Efficacy evaluation:

[0071] 1. Color protection test

[0072] The bleached hair of Chinese people was treated with a commercially available hair dye to produce damaged hair bundles with an effective length of 25 cm, a width of 3 cm, and an effective weight of 8 g. The hair dye was applied to the damaged hair bundles according to a weight ratio of hair dye: hair = 1:1, and after being left at room temperature for 30 minutes, the hair bundles were rinsed with room temperature water for 1 minute, and then dried with a hair dryer for 20 minutes; the dyed hair bundles were then washed with the shampoo products described in the test examples and comparative examples, and then dried with a hair dryer for 20 minutes. This operation was repeated 10 times, and the color difference dE of the hair bundles was measured using a colorimeter (Konica Minolta colorimeter CM-3600A). * (Including L * 、a * and b * value); measure the chromaticity difference dE of the hair strand just after dyeing * 1 value, dE * The calculation formula for 1 is: (Where L *0.a * 0 and b * 0 represents L before dyeing * 、a * and b * The value of L * 1.a * 1 and b * 1 represents the L after dyeing * 、a * and b * ); Measure the color difference dE of the hair bundle after repeated washing 10 times using the shampoo products described in the test examples and comparative examples * 2 value, dE * The calculation formula for 2 is: (Where L * 0.a * 0 and b * 0 represents L before dyeing * 、a * and b * The value of L * 2.a * 2 and b * 2 respectively represent the L after washing of the test example and the comparative example * 、a * and b * ), and then calculate the color protection degree ΔdE * =dE * 1-dE * 2, ΔdE * The smaller it is, the better its color protection is.

[0073] The shampoo products of Test Examples 1-8 and Comparative Examples 1-6 were tested for color protection, and the test results are shown in Table 5 below:

[0074] Table 5 Test results of color protection of shampoo products of Test Examples 1-8 and Comparative Examples 1-6

[0075]

[0076]

[0077] It can be seen from the test results in Table 5 that the shampoo products of Test Examples 1-8 have excellent color protection effects compared with Comparative Examples 1-6, and the color protection effects of the test examples increase with the increase in the amount of the repair and color protection composition of the present invention. In addition, the test results in Table 5 further show that the four components in the repair and color protection composition are indispensable, and the ratio of the four components must be within the scope of the present invention to have a synergistic effect.

[0078] 2. Protection from heat damage test (flat ironing)

[0079] Using healthy hair of Chinese people, hair bundles with effective length of 25 cm, width of 3 cm and effective weight of 8 g were made. Negative control group: hair bundles without any treatment; Blank control group: hair bundles were washed with SLES solution (10%) and dried at room temperature; hair was permed with a standard BaByliss Pro flat plate, the temperature was set to 210°C, the action time was 10s, the action was repeated 9 times, and then the denaturation temperature T of the hair was measured with a differential scanning calorimeter (DSC); Test group: hair bundles were washed with SLES solution (10%) and dried at room temperature; then the shampoo products of test examples 1-8 and comparative examples 1-6 were applied to the hair bundles for 5 minutes, then washed with clean water for 1 minute and dried at room temperature; hair was permed with a standard BaByliss Pro flat plate, the temperature was set to 210°C, the action time was 10s, the action was repeated 9 times, and then the denaturation temperature T of the hair was measured with a differential scanning calorimeter (DSC); In addition, the lower the denaturation temperature T, the higher the degree of structural damage of the hair.

[0080] The test results of the shampoo products of the negative control group, blank control group, test examples 1-8 and comparative examples 1-6 for protecting hair from heat damage are as follows: Figure 1 As shown. Figure 1 From the test results, it can be seen that the denaturation temperatures of hair in Test Examples 1-8 of the present invention are higher than those in Comparative Examples 1-6, that is, the shampoo products in the Test Examples of the present invention can reduce the thermal damage of hair. The shampoo product (Comparative Example 1) without the addition of the repair and color protection composition of the embodiment of the present invention has the worst thermal damage protection for hair; the lack of any one of the four components in the repair and color protection composition of the embodiment of the present invention will weaken the synergistic effect, for example, the thermal damage protection of Comparative Examples 2-5 is worse than that of Test Examples 3-6; in addition, the four components of the repair and color protection composition of the embodiment of the present invention need to be in a certain proportion to synergize and exert the maximum effect, for example, Comparative Example 6 contains the four components of the repair and color protection composition, but it is not within the ratio of the four components specified by the present invention, and the thermal damage protection of hair in Comparative Example 6 is lower than that of the various Test Examples of the present invention. In summary, the repair and color protection composition of the embodiment of the present invention can rebuild the hair structure from the inside, protect the hair from thermal damage, and protect the internal structure of the hair.

[0081] 3. Tensile strength (fracture resistance) test

[0082] The hair of Chinese people was treated with a commercially available bleach to prepare damaged hair bundles with an effective length of 25 cm, a width of 3 cm and an effective weight of 8 g. 15 damaged hair bundles were selected, and the hair was washed with a SLES solution (10%) and dried at room temperature. Then, deionized water (blank control group), the shampoo products of Test Examples 1-8 and Comparative Examples 1-6 were applied to the hair for 5 minutes, washed with clean water for 1 minute, and dried at room temperature. 50 hair strands with a diameter difference of less than 10 μm were selected from each of the 15 hair bundles, and the hair was subjected to a tensile strength test using a hair fatigue tensile performance tester (CYC-801), and the number of unbroken hair strands was calculated. The test was repeated 500 times, and the number of unbroken hair strands was finally calculated.

[0083] The shampoo products of Test Examples 1-8 and Comparative Examples 1-6 were subjected to a tensile strength (fracture resistance) test. The test results are shown in Table 6.

[0084] Table 6 Test results of tensile strength (fracture resistance) of shampoo products of blank control group, test examples 1-8 and comparative examples 1-6

[0085]

[0086]

[0087] From the test results in Table 6, it can be seen that the hair breakage resistance of each of the test examples 1-8 of the present invention is higher than that of the comparative examples 1-6, indicating that the shampoo product containing the repair and color protection composition of the present invention has the effect of repairing damaged hair, resisting breakage, and improving the toughness of hair. Comparative Example 1 does not add the repair and color protection composition of the embodiment of the present invention, and has the worst hair breakage resistance performance; the lack of any one of the four components of the repair and color protection composition will weaken the synergistic effect, for example, the breakage resistance performance of comparative examples 2-5 is worse than that of test examples 3-6; in addition, the four components of the repair and color protection composition need to be in a certain proportion to play the maximum role in synergy, for example, comparative example 6 contains the four components of the repair and color protection composition, but it is not within the ratio of the four components of the repair and color protection composition specified by the present invention, and the hair breakage resistance performance of comparative example 6 is lower than that of each test example of the present invention. In summary, the repair and color protection composition of the embodiment of the present invention can repair the internal structure of hair, strengthen hair, resist breakage, and repair damaged hair.

[0088] 4. Scalp barrier function test and combability and color protection effect test

[0089] In order to further demonstrate the beneficial effects of the repairing and color protecting composition and shampoo product provided by the present invention, the scalp barrier function test and the combing properties and color protecting effects of the test examples of the present invention and the comparative examples are evaluated below.

[0090] Test samples: Test Examples 1-6 and Comparative Examples 1-6.

[0091] Test method: 60 testers who had just dyed their hair were selected, with an age distribution between 20 and 45 years old. They were randomly divided into 6 groups and a half-head comparison test was conducted. Each tester used the test example on the left side and the control example on the right side.

[0092] Before the testers use the test samples, a one-week washout period is set, that is, the same shampoo without color protection function is used for one week, three times a week, to avoid the impact of the original shampoo product on the scalp and hair. After the washout period, the shampoo products of the test example and the comparative example are used, with the amount of a one-yuan coin on both sides each time, and used three times a week. The relevant indicators are evaluated before and 28 days after the use of the test samples.

[0093] Scalp barrier function test: This experiment uses the German CK skin water loss test probe Corneometer CM825 to test the changes in the transepidermal water loss (TEWL) of the scalp: The TEWL value is used to evaluate the barrier function of the scalp. The smaller the value, the better the barrier function of the scalp. Transepidermal water loss change rate Among them, x 使用前 is the TEWL value before using the test product, x 使用前 It is the TEWL value after 28 days of using the test product.

[0094] Evaluation of combability: A scoring system is adopted, and the scoring criteria are: 5 points represent very easy to comb, 4 points represent easy to comb, 3 points represent average, 2 points represent not easy to comb, and 1 point represents very difficult to comb.

[0095] Evaluation of color protection effect: a scoring system is adopted, and the scoring standard is: 5 points represent very obvious color protection, 4 points represent obvious color protection, 3 points represent average color protection, 2 points represent unobvious color protection, and 1 point represents very unobvious color protection.

[0096] The scalp barrier function test results of Test Examples 1-6 of the present invention and Comparative Examples 1-6 are shown in Table 7 below:

[0097] Table 7 Scalp barrier function test results of shampoo products of Test Examples 1-6 and Comparative Examples 1-6

[0098] Test samples TEWL change rate η / % Test Example 1 -14.56 Test Example 2 -15.23 Test Example 3 -16.89 Test Example 4 -17.82 Test Example 5 -15.9 Test Example 6 -14.91 Comparative Example 1 -1.23 Comparative Example 2 -2.34 Comparative Example 3 -2.45 Comparative Example 4 -2.95 Comparative Example 5 -2.91 Comparative Example 6 -3.01

[0099] According to the test results in Table 7, compared with the comparative example, the TEWL change rate of the tester using the shampoo product of the test example presents a negative value, and the absolute value is significantly higher than the comparative example, indicating that test examples 1-6 can significantly reduce the TEWL value and improve the barrier function of the scalp. Comparative Example 1 does not add the repair and color protection composition of the embodiment of the present invention, and its absolute value of TEWL change rate is the lowest, and there is no significant improvement in the scalp barrier; Comparative Examples 2-5 all add any three components of the repair and color protection composition of the embodiment of the present invention, but there is no significant improvement in the scalp barrier function, but the test examples that add the repair and color protection composition of the embodiment of the present invention all have a significant improvement in the scalp barrier function. Compared with Comparative Example 2 and Comparative Example 6, although Comparative Example 6 adds the four components of the repair and color protection composition of the present invention, the improvement of the scalp barrier function is obviously not as good as that of Example 2, which further illustrates that the four components of the repair and color protection composition of the present invention must meet a specific ratio in order to better achieve the improvement of the scalp barrier function. In summary, the repairing and color protecting composition of the present invention can effectively enhance the barrier function of the scalp. It further illustrates that the various components of the repairing and color protecting composition of the present invention are synergistic with each other and can only exert the maximum effect according to a specific ratio.

[0103] According to the test results in Table 8, compared with the comparative examples, the shampoo products using the test examples all have excellent combing performance and color protection effects. Comparative Examples 2-5 all add any three components of the repair and color protection composition of the embodiment of the present invention, but there is no obvious improvement in the combing performance and color protection effect of the hair, but the test examples adding the repair and color protection composition of the embodiment of the present invention all have very obvious effects on the combing performance and color protection effect of the hair; Compared with Test Example 2 and Comparative Example 6, although Comparative Example 6 adds the four components of the repair and color protection composition of the embodiment of the present invention, the combing performance and color protection effect of the hair are not as good as those of Example 2, which further illustrates that the four components of the repair and color protection composition of the present invention must meet a specific ratio in order to better achieve the improvement of the combing performance and color protection effect of the hair. In summary, the repair and color protection composition of the present invention can effectively improve the combing performance of the hair and have an excellent color protection effect, and further illustrates that the various components of the repair and color protection composition of the present invention are mutually synergistic and can only play the maximum role according to a specific ratio.
