Description

Technical Field

[0001] This invention belongs to the technical field of daily shampoo and hair care raw materials, specifically relating to a hair care composition containing plant extracts and its application. Background Technology

[0002] Hair is composed of keratin fibers, and its outer cuticle layer is a crucial barrier that maintains the smoothness, strength, and shine of the hair. Daily combing friction, high-temperature styling, ultraviolet radiation, air pollution, and frequent perming and dyeing can all cause the cuticles to lift and fall off, damaging the hair's integrity and leading to problems such as dryness, frizz, dullness, decreased resilience, and split ends. Meanwhile, the scalp is the foundation of hair growth, and its health directly determines the quality of the hair.

[0003] Currently, many shampoo and conditioner products on the market have numerous shortcomings. Most products focus on scalp cleansing while neglecting deep nourishment and repair of the scalp and hair, failing to fundamentally improve damaged hair and effectively address core issues such as dryness, brittleness, and breakage. Some hair care products, in pursuit of immediate smoothness, add excessive amounts of chemical softeners, which can lead to increasingly dry hair and an unbalanced scalp with long-term use.

[0004] As living standards improve, consumers' demand for healthy hair and scalp care is constantly increasing. Therefore, this application proposes a hair care composition containing plant extracts and its application, aiming to achieve deep nourishment of hair and scalp through plant active ingredients, repair damaged hair cuticles, improve dry hair quality, strengthen hair strands, and meet the public's demand for healthy and efficient hair care.

[0034] The total weight of each composition in Examples 1-3 is the same as that in Comparative Examples 1-8.

[0035] Example 1 of efficacy test: Composition test Test sample preparation: The hair care compositions of Examples 1-3 and Comparative Examples 1-8 were diluted with deionized water to a concentration of 3% for the test sample solution; 1) Test of dry / wet combing work change rate and tensile work change rate Hair strand pretreatment: 36 strands of damaged hair bleached with hydrogen peroxide were selected and randomly divided into 12 groups, with 3 strands in each group; before testing, the hair strands were cleaned with a 3% SDS aqueous solution and air-dried at room temperature for later use. Experimental Procedure: The hair bundle was fixed with a test clip for combing and breaking tests, recorded as dry hair combing ability (A0) and breaking ability (C0) before using the test sample. The hair bundle was then soaked in deionized water, combed, gently kneaded, rinsed, and then fixed with a test clip for combing ability testing; this was recorded as wet hair combing ability before use (B0). After air-drying, 1.5 mL of test sample was gently and evenly applied to the upper, middle, and lower sections of the hair bundle. The blank control group used an equal amount of deionized water. Using deionized water instead of the test sample, the hair was allowed to dry and then rinsed with 38℃ deionized water for 15 seconds. The hair strand was then fixed with a test clip for combing performance testing, which was recorded as the wet hair combing performance after using the test sample (referred to as B1). After drying, the hair strand was fixed with a test clip for combing performance and breakage performance testing, which were recorded as the dry hair combing performance after using the test sample (referred to as A1) and the breakage performance after using the test sample (referred to as C1). The change rate of dry / wet hair combing performance and the change rate of breakage performance were calculated according to the following formulas, and the data are presented as average values ​​in Table 2. ; In the formula: A0 is the dry hair combing effort of the hair bundle before using the test sample; A1 is the dry hair combing effort of the hair bundle after using the test sample. ; In the formula: B0 is the combing effort of the hair bundle before using the test sample; B1 is the combing effort of the hair bundle after using the test sample. ; In the formula: C0 is the breaking power of the hair bundle before using the test sample; C1 is the breaking power of the hair bundle after using the test sample; 2) Hair shine test Hair strand pretreatment: 36 strands of damaged hair bleached with hydrogen peroxide were selected and randomly divided into 12 groups, with 3 strands in each group; before testing, the hair strands were cleaned with a 3% SDS aqueous solution and air-dried at room temperature for later use. Experimental Procedure: Gently and evenly apply 1.5 mL of the test sample to the upper, middle, and lower sections of the hair strand. The blank control group uses an equal volume of deionized water instead of the test sample. After allowing the hair strands to air dry, rinse with 38℃ deionized water for 15 seconds, and allow to air dry before testing. Before and after applying the test sample, fix the hair strand with a test clip and test the glossiness of the hair strand surface using a skin glossiness probe. The data before applying the test sample is recorded as X0, and the data after applying the test sample is recorded as X1. Calculate the rate of change in hair glossiness before and after applying the test sample using the following formula. Take the average value of the test results. See Table 2 for specific experimental results. A positive rate of change in hair glossiness indicates that the test sample has a brightening effect on the hair. ; In the formula: X0 is the gloss of the hair strand before using the test sample; X1 is the gloss of the hair strand after using the test sample; Table 2 Test data of the composition

[0036] As can be seen from the data in Table 2 regarding the changes in wet hair combing power, dry hair combing power, breakage power, and gloss in Examples 1 and Comparative Examples 1-6, whether any one of the following is reduced (e.g., Artemisia argyi extract, red yeast rice / rice fermentation product, Lysimachia chrysanthemum / leaf / vine extract, and watercress extract), or other components are used to replace the red yeast rice / rice fermentation product, the resulting composition shows a significant decrease in its effects on improving combing power, strengthening hair, and improving hair gloss. This indicates that the Artemisia argyi extract, red yeast rice / rice fermentation product, Lysimachia chrysanthemum / leaf / vine extract, and watercress extract selected in this invention have a significant synergistic effect.

[0037] As can be seen from Examples 1-3 and Comparative Examples 7-8 in Table 2, the ratio of the amounts of Artemisia argyi extract, red yeast rice / rice fermentation product, Lysimachia chrysantha flower / leaf / vine extract, and watercress extract affects the efficacy of the composition. When the weight ratio of Artemisia argyi extract, red yeast rice / rice fermentation product, Lysimachia chrysantha flower / leaf / vine extract, and watercress extract is (5-7):(2-3.5):(4-7):(3-5), the resulting composition has a better effect on improving combing power, strengthening hair, and improving hair shine. When the weight ratio of Artemisia argyi extract, red yeast rice / rice fermentation product, Lysimachia chrysantha flower / leaf / vine extract, and watercress extract is further optimized to 6:3:5.5:4, the resulting composition has an even better effect.

[0038] Application example: A hair care serum The compositions prepared in Examples 1-3 and Comparative Examples 1-8 were added to hair serums to obtain hair serums of Application Examples 1-3 and Comparative Application Examples 1-8, respectively.

[0039] The hair care essence comprises the following components in weight percentage: 0.2% carbomer, 0.1% aminomethylpropanol, 0.2% dipotassium glycyrrhizate, 0.5% trehalose, 0.6% 1,2-hexanediol, 0.5% p-hydroxyacetophenone, 10% ethanol, 3% hair care composition, and the balance being deionized water.

[0040] The preparation method of the hair care essence specifically includes the following steps: Step 1: Add carbomer to deionized water, start heating to 60°C and then stop heating, and stir homogenize for 30 minutes; Step 2: Cool down to 45℃, add aminomethylpropanol, stir well, then add dipotassium glycyrrhizate, trehalose, 1,2-hexanediol and p-hydroxyacetophenone, and stir for 20 minutes. Step 3: When the temperature drops to 37°C, add ethanol and the hair care composition, stir for 20 minutes, and the hair care essence is obtained.

[0041] Blank application example: Compared with application examples 1-3, the difference is that the hair essence in the blank application example does not contain a hair care composition, and uses an equal amount of deionized water instead of the hair care composition containing plant extracts. The preparation method is the same as that in application examples 1-3.

[0042] Example 2: Efficacy Test of Hair Serum The hair care serums prepared in Application Examples 1-3, Comparative Application Examples 1-8, and Blank Application Examples were used as samples to test their hair care effects.

[0043] Test samples: hair serums prepared in Application Examples 1-3, Comparative Application Examples 1-8, and Blank Application Example; Test Procedure: A total of 120 participants were included, 60 women and 60 men, aged 20-40 years (mean age 28 years). They were randomly assigned to groups of 10 volunteers each. Each group applied 1.5 mL of hair serum to their scalp once daily for 28 days. Participants sat quietly for 30 minutes at 21±1℃ and 50±10% humidity. Transdermal water loss was measured on the top of the scalp using a Tewameter TM330T probe before application. After the test, participants took the hair serum home and used it after each shampoo (every two days). Transdermal water loss was measured again under the same conditions and at the same location after 28 days. Participants were required to shampoo their hair during the test, and to wash their hair the day before the test. The reduction rate of transdermal water loss was calculated using the following formula, and the data are presented as averages. ; Where: T0 is the transdermal water loss value before using the test sample; T1 is the transdermal water loss value after using the test sample for 28 days; Table 3. Transdermal water loss test data

[0044] As can be seen from the transdermal water loss rate data of Application Example 1 and Comparative Application Examples 1-6 in Table 3, whether any one of the following is reduced: Artemisia argyi extract, red yeast rice / rice fermentation product, Lysimachia christinae flower / leaf / vine extract and watercress extract, or other components are used to replace red yeast rice / rice fermentation product, the hair care essence has a significantly reduced hair care effect. This indicates that the Artemisia argyi extract, red yeast rice / rice fermentation product, Lysimachia christinae flower / leaf / vine extract and watercress extract selected in this invention have a significant synergistic effect.

[0045] As can be seen from the transdermal water loss rate data of Application Examples 1-3 and Comparative Application Examples 7-8 in Table 3, the ratio of the amounts of Artemisia argyi extract, red yeast rice / rice fermentation product, Lysimachia chrysantha flower / leaf / vine extract, and watercress extract affects the performance of the hair care essence. When the weight ratio of Artemisia argyi extract, red yeast rice / rice fermentation product, Lysimachia chrysantha flower / leaf / vine extract, and watercress extract is (5-7):(2-3.5):(4-7):(3-5), the hair care essence has a better hair care effect. When the weight ratio of Artemisia argyi extract, red yeast rice / rice fermentation product, Lysimachia chrysantha flower / leaf / vine extract, and watercress extract is further optimized to 6:3:5.5:4, the hair care essence has an even better effect.

[0046] Example 3: Patch Test Test samples: Samples provided in Application Examples 1-3 and Comparative Application Examples 1-8; This efficacy test case uses the 2015 "Cosmetic Safety Technical Specifications" as the reference standard to evaluate the irritation of cosmetics. The test method is a skin patch test, and 110 people aged 16-65 years were randomly distributed to participate in the test, with 10 people in each group. Test method: Place the test substance into a patch applicator at a dosage of 0.020-0.025g. Cover the patch applicator containing the test substance with non-irritating cloth-based adhesive tape and apply it to the flexor side of the subject's forearm. Gently press with the palm of your hand to ensure even adhesion to the skin surface. Leave it on for 24 hours. Remove the patch applicator 30 minutes after the pressure mark disappears and observe the skin reaction. If the result is negative, observe again at 24 hours and 48 hours after the patch test. Evaluation criteria: Grade 0: Negative reaction; Grade 1: Suspicious reaction, only slight erythema; Grade 2: Weak positive reaction, erythema, infiltration, edema, and possible papules; Grade 3: Strong positive reaction, erythema, infiltration, edema, and possible papules, reaction may extend beyond the test area; Grade 4: Very strong positive reaction, obvious erythema, severe infiltration, edema, confluent herpes, reaction extends beyond the test area.

[0047] After testing, the hair care essences prepared in Application Examples 1-3 and Comparative Application Examples 1-8 of this invention showed negative reactions after human patch testing, proving their safety and effectiveness.
