Description

Technical Field

[0001] This invention belongs to the field of cosmetic technology and discloses a scalp care composition and its uses, as well as a daily chemical product. Background Technology

[0002] In today's society, as people pay more and more attention to the health and appearance of their scalp and hair, coupled with the high work and life pressures and irregular eating habits, the pressure on the scalp and hair follicles is further aggravated. In particular, scalp aging is accompanied by multiple manifestations such as damage to the scalp barrier, thinning and loosening of the scalp, itching and inflammation of the scalp, thinning of hair, and hair loss.

[0003] Currently, the market offers a wide variety of shampoos targeting these scalp problems, but each product has limitations and offers only one function, such as oil control, dandruff removal, cleansing, volumizing, and hair loss prevention. These products often overlook the root cause of scalp and hair damage: oxidative stress. The scalp secretes a large amount of sebum daily, including triglycerides and free fatty acids. When sebum is exposed to ultraviolet rays, pollutants, or microbial metabolism, lipid peroxidation easily occurs, producing reactive oxygen species (ROS) such as malondialdehyde and 4-hydroxynonenal, which directly stimulate scalp cells. Simultaneously, the scalp contains approximately 100,000 hair follicles, each undergoing a cyclical "anagen-catagen-telogen" phase, dependent on the activity of hair follicle stem cells. These stem cells are extremely sensitive to oxidative damage, and ROS accumulation directly impairs their proliferative and differentiation capabilities. Furthermore, the thin stratum corneum of the scalp is easily damaged by frequent cleaning and combing, making it easier for ROS to penetrate the dermis and damage blood vessels and connective tissue. Oxidative stress can damage scalp health through multiple pathways, forming a "damage chain" that directly damages hair follicles, disrupts the scalp barrier, leads to decreased hair quality and hair loss, triggers sensitivity and inflammation, and exacerbates bacterial imbalance.

[0004] Therefore, the technical problem to be solved in this case is: how to develop a composition that can provide comprehensive care for the scalp and hair. Summary of the Invention

[0005] The purpose of this invention is to provide a scalp care composition that, based on aloe vera flower extract and vitamin E, utilizes antioxidants in combination with panthenol and sodium hyaluronate to achieve a synergistic effect, enabling the composition to provide better comprehensive care for the scalp and hair when added to shampoo; furthermore, the addition of traditional Chinese medicine ingredients further enhances this effect.

[0047] Part One Experiment

[0048] This part of the experiment mainly screened combinations of aloe vera flower extract with vitamin E and antioxidant factors based on their antioxidant effects.

[0049] The formulations of each composition are shown in Table 1.

[0050] Table 1. Formulation of Antioxidant Compositions (parts by weight)

[0051]

[0052] Compositions 1 to 10 were subjected to DPPH free radical scavenging tests according to the following method;

[0053] Prepare a 0.1 mmol / L DPPH solution. Take 2 ml of DPPH solution and mix it with 2 ml of sample solutions of composition 1 to 10. After mixing, react in a water bath at 25°C for 30 min in the dark. Measure the absorbance at 517 nm using a UV spectrophotometer.

[0054] DPPH free radical scavenging rate = (1-(A1-A3) / A2)*100%;

[0055] Where A1 is the absorbance of the sample solution and DPPH solution, A2 is the absorbance of the DPPH solution and diluent, and A3 is the absorbance of the sample solution and diluent.

[0056] The results are shown in Table 2.

[0057] Table 2 DPPH Removal Rate Data Table

[0058]

[0059]

[0060] As can be seen from the results in Table 2, Composition 1 has the highest DPPH scavenging rate and the best antioxidant effect. Therefore, Composition 1 is used as the base formulation, and then combined with antioxidants. The formulation is shown in Table 3.

[0061] Table 3 Formulation Table (parts by weight)

[0062]

[0063] Compositions 11-19 and individual components 1-4 were tested according to the above-described DPPH free radical scavenging test method, and the results are shown in Table 4.

[0064] Table 4 DPPH Removal Rate Data Table

[0065] Composition 11 89.13 Composition 12 81.45 Composition 13 81.43 Composition 14 82.42 Composition 15 79.05 Composition 16 79.84 Composition 17 79.25 Composition 18 76.28 Composition 19 76.88 Ingredients 1 72.5 Ingredient 2 61.34 Ingredient 3 35.9 Ingredient 4 58.18

[0066] As can be seen from the results in Table 4, compositions 11 to 14 have high DPPH scavenging rates, all above 80%, indicating better antioxidant effects, with composition 11 showing the best results.

[0067] Part Two Experiments

[0068] As can be seen from the results in Part 1, compositions 11-14 have better antioxidant effects. Therefore, using compositions 11-14 as a new basic formula, they are compounded with aloe vera macromolecular gel powder, panthenol, sodium hyaluronate and traditional Chinese medicine ingredients to obtain the scalp care composition formula of the present invention. The scalp care composition formulas of each embodiment and comparative example are shown in Table 5.

[0069] Table 5. Scalp Care Composition Formulation (parts by weight)

[0070]

[0071] The scalp care compositions obtained in the above embodiments and comparative examples were prepared into shampoos according to the formulation table in Table 6;

[0072] Table 6 Shampoo Formula Table

[0073]

[0074]

[0075] The preparation method is as follows:

[0076] 1. Add deionized water and hydroxypropyl guar gum hydroxypropyltrimethylammonium chloride, stir for 2 minutes, then add disodium EDTA;

[0077] 2. Add sodium lauryl ether sulfate and cocamidopropyl hydroxysulfonate, and stir for 20 minutes until the ingredients are completely dissolved;

[0078] 3. Add avocado oil PEG-11 esters, scalp care composition, phenoxyethanol, and sodium benzoate, and stir for 20 minutes until the ingredients are completely dissolved;

[0079] 4. Adjust the pH value with citric acid and add cocamide methyl MEA to adjust the consistency.

[0080] The shampoos prepared from the scalp care compositions of each embodiment and comparative example were subjected to the following tests:

[0081] Sensory evaluation by professionals

[0082] A panel of five professional hair care evaluators conducted a blind test on treated hair strands, calculating the average score based on a scale (1-5 points):

[0083] Shine: Does it have a natural shine? Softness: How stiff does the hair feel when bent? Overall healthiness;

[0084] The results are shown in Table 7.

[0085] Table 7 Scoring Table

[0086]

[0087]

[0088] As can be seen from the results in Table 7, the shampoos of Examples 1-4 all scored highly in terms of smoothness, shine, and overall health. This indicates that the scalp care composition obtained by compounding aloe vera flower extract, vitamin E, honeysuckle extract, camellia seed extract, bisabolol, grape seed extract, aloe vera macromolecular gel powder, panthenol, sodium hyaluronate, arborvitae leaf extract, and ginger root extract has a good comprehensive care effect on the scalp and hair.

[0089] Data from Examples 5-8 show that, while maintaining the same dosage, replacing the ginger root extract with ginseng extract, Polygonum multiflorum extract, or Angelica sinensis extract, or using Platycladus orientalis leaf extract alone, resulted in shampoos with relatively high scores, second only to the shampoos from Examples 1-4.

[0090] The data from Comparative Example 1 demonstrate that a basic combination of any one of the following extracts—Aloe vera flower extract, vitamin E, honeysuckle extract, camellia seed extract, bisabolol, and grape seed extract—is indispensable.

[0091] Comparing Comparative Example 2 with Example 1, Comparative Example 3 with Comparative Example 4, and Comparative Example 5 with Comparative Example 6, it can be seen that, with the other ingredients remaining the same, the lack of antioxidant factors resulted in a significant decrease in the shampoo's score, indicating that antioxidant factors are also indispensable.

[0092] Data from Examples 1, 2, 3, and 5 show that the antioxidant, panthenol, and sodium hyaluronate have a synergistic effect in increasing the overall score of the shampoo. All three substances must be used simultaneously; none can be omitted. Data from Comparative Examples 7-11 further illustrate this conclusion. Replacing panthenol with glycerin, propylene glycol, or butylene glycol—substances known in the art to have similar effects—significantly reduced the overall score of the resulting shampoo; similarly, replacing sodium hyaluronate with glycerin yielded the same result.

[0093] Stability test

[0094] The shampoos of Examples 1 to 8 were subjected to stability tests in the following manner;

[0095] Stability (high temperature, low temperature, and light exposure tests): The formulation samples were placed at 48℃, -18℃, and under light exposure for 8 weeks to test the stability of the products. The results are shown in Table 8.

[0096] Table 8 Stability Test Results

[0097]

[0098] As can be seen from the results in Table 8, the shampoos obtained by the technical solution of the present invention all have good stability. After being tested for 8 weeks under high temperature, low temperature and light, almost none of them showed any discoloration or change in smell. Only Examples 6 and 7 showed slight discoloration and change in smell. Therefore, the preferred traditional Chinese medicine ingredients in the technical solution of the present invention are Arborvitae Leaf Extract and Ginger Root Extract.

[0099] Human efficacy test

[0100] This study recruited individuals with damaged / sensitive scalp barriers, enrolling 48 participants aged 21-47 years. Volunteers were randomly divided into four groups of 12 each. Upon their first visit, volunteers were given shampoos (Examples 1, 2, Comparative Example 2, and Comparative Example 9) and used them continuously for 28 days, at least three times per week. Follow-up testing was conducted after 28 days. Measurements included scalp stratum corneum water content and transepidermal water loss. The stratum corneum water content results are shown in Table 9. Figure 1 As shown in Table 10, the results of transdermal water loss are as follows: Figure 2 As shown.

[0101] Table 9. Data on water content in the stratum corneum

[0102]

[0103]

[0104] Table 10 Transdermal water loss values

[0105]

[0106] After volunteers used the shampoo containing a comprehensive conditioning composition for 28 consecutive days, the scalp stratum corneum moisture content of Examples 1 and 2 significantly increased, and the transepidermal water loss value significantly decreased, indicating enhanced scalp barrier function, primarily due to the scalp's antioxidant effect. Comparative Example 2 showed an increase in scalp stratum corneum moisture content but did not reduce scalp transepidermal water loss value; Comparative Example 9 showed no significant changes in scalp stratum corneum moisture content or transepidermal water loss value, and the scalp barrier function was not improved.

[0107] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
