Description

Technical Field

[0001] This invention relates to the field of daily chemical products technology, specifically to a hair-volumizing composition and its application. Background Technology

[0002] With rapid economic development and improved living standards, people are paying more and more attention to their appearance. They are no longer satisfied with just skincare; more and more people are focusing on hair and scalp care, making shampoo an indispensable daily necessity. Shampoo is a personal care product that removes dirt from the scalp and hair, inhibits dandruff and scalp itching, and keeps hair and scalp clean and healthy. However, due to the diversification of people's needs, shampoo and conditioner products with various additional functions are also gradually becoming popular.

[0003] With increasing societal pressures, hair loss is becoming a more serious problem, leading to thinning hair. Choosing the wrong shampoo can exacerbate this issue, severely impacting one's appearance. However, sufficient volume can visually increase hair volume. For those with curly hair, adding volume makes the hairstyle look more perfect. Furthermore, consumers with fine, soft hair and oily scalps who frequently experience flat, limp hair also have a high demand for volumizing shampoos.

[0004] "Volumsy" describes hair that appears layered and spaced, rather than flat and lifeless. According to the "2021 Scalp Health White Paper," volumizing has become a popular trend. Most shampoos on the market currently use cationic conditioners (such as polyquaternium-11) to promote hair volume, essentially using the repulsive force of cationic charges to keep hair voluminous. Cationic conditioners adhere to the hair surface through charge action, exhibiting stronger accumulation than silicone oil. However, this makes hair more prone to absorbing more dust particles when in contact with the air, constantly stimulating the scalp to secrete oil, which mixes with the dust to form grease, exacerbating oiliness. Furthermore, with increased usage, the accumulation of cationic substances further increases, tightly encasing pores, blocking hair follicle respiration, causing insufficient oxygenation, gradual atrophy of the hair papilla, and ultimately, hair loss. While cationic conditioners can achieve good hair conditioning effects such as smoothness in the short term, long-term use reduces the shampoo's cleansing power, diminishes oil control and volumizing effects, and increases scalp oil production.

[0005] In summary, currently available shampoos generally have limited volumizing effects, and repeated use can easily lead to oily hair, making it heavier and exacerbating the problem of limp hair. Therefore, there is an urgent need in this field to develop a composition that can both provide volumizing effects and control oil production. Summary of the Invention

[0031] It should be understood that, within the scope of this invention, the above-described technical features of this invention and the technical features specifically described below (such as in the embodiments) can be combined with each other to form new or preferred technical solutions. Due to space limitations, they will not be described in detail here. Attached Figure Description

[0032] Figure 1 Images of hair strands after using shampoo sample 1 (BASE) and sample 9 (BASE + active ingredient) are shown.

[0033] Figure 2 The results show the increase in hair volume after using shampoo samples 1–9. Detailed Implementation

[0034] Through long-term and in-depth research and extensive screening, the inventors have developed for the first time a composition that can both volumize and control oil in hair. Hydroxypropyltrimethylammonium chloride hydrolyzed wheat protein, oat active peptides, and zinc pyrrolidone carboxylate (PCA zinc) are all common additives in cosmetics and hair care products. However, the inventors unexpectedly discovered that combining the traditional cationic conditioner polyquaternium-11 with the above components not only provides excellent volume but also overcomes the drawback of traditional cationic conditioners causing excessive oil production. Based on this, the inventors completed this invention.

[0035] The main advantages of this invention are:

[0036] 1. This invention utilizes an in vitro oil-containing hair strand model and, based on the Visia-CR 5.0 testing instrument, obtains the volume area of ​​hair strands after using different sample compositions through image contrast analysis, thereby evaluating the volume effect of the composition samples. The experimental results show that the volume enhancement rate of the shampoo base is only 104.6%, while the volume enhancement rate is significantly higher after adding the composition of this invention to the shampoo base, reaching a maximum of 227.4%.

[0037] 2. This invention utilizes consumer testing to evaluate the volumizing, oil-controlling, and gentle effects of a shampoo base and a shampoo base with the composition of this invention added after a single use, 7 days of use, and 28 days of use. The experimental results show that the shampoos with the composition of this invention added achieved significantly higher levels of satisfaction in terms of volumizing, oil control, and gentleness compared to the shampoo base alone. This indicates that the composition of this invention has a significant volumizing effect and does not cause oiliness or a decrease in volumizing effect with prolonged use.

[0038] 3. The compositions of the present invention can be combined with different formulation systems and can be used in products such as shampoos and conditioners.

[0039] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Experimental methods in the following embodiments, unless otherwise specified, were generally performed under conventional conditions or as recommended by the manufacturer. Unless otherwise stated, percentages and parts are weight percentages and parts by weight.

[0040] Example 1: In vitro hair volumization test of shampoo base and hair bundle containing functional composition.

[0041] The sample configuration is shown in Table 1 below.

[0042] Table 1. Sample Information for In Vitro Hair Bundle Experiment

[0043]

[0044] The specific formula of the base shampoo used in this embodiment is as follows:

[0045] Element Amount added (wt%) Sodium lauryl ether sulfate 5-20wt% Cocamidopropyl Betaine 1-5wt% essence 0.1-5wt% Sodium chloride 0.1-5wt% PEG-150 distearate 0.1-5wt% Phenoxyethanol 0.1-5wt% glycerin 0.001-5wt% Citric acid 0.001-5wt%

[0046] Experimental steps and results:

[0047] 1. Hair tie cleaning

[0048] Clean all hair strands with 10% sodium lauryl ether sulfate (SLES) and let them air dry in a constant temperature and humidity environment.

[0049] 2. Apply oil

[0050] Apply olive oil evenly to the hair strands using a cotton cloth, with an application amount of 0.3±0.05g / g of hair strand.

[0051] 3. Take a photo

[0052] Each strand of hair was photographed using VISIA-CR mode (standard 1).

[0053] 4. Cleaning

[0054] Wet the hair strand with running water, take 0.3g of the shampoo sample from Table 1 and apply it evenly to the hair strand, massage 20 times, rinse for 30 seconds, and let it sit overnight at a constant temperature and humidity.

[0055] 5. Take photos

[0056] Each hair strand was photographed using VISIA-CR mode (standard 1), with images of sample 1 (BASE) and sample 9 (BASE + active ingredient) as shown below. Figure 1 As shown.

[0057] 6. Data Processing and Result Analysis

[0058] Data processing: Based on the number of pixels in the hair strand region and the total number of pixels in the image, the hair strand area ratio is calculated, i.e., hair strand area ratio = number of pixels in the hair strand region / total number of pixels in the image × 100%. The results are shown in Table 2 below. Figure 2 As shown.

[0059] Table 2 Summary of In Vitro Hair Bundle Experiment Results

[0060] Sample Name Hairline area before application / % Hair area after use / % Fluffing improvement rate / % Sample 1 (base group) 4.32 8.84 104.60 Sample 2 4.20 9.56 127.60 Sample 3 3.98 11.78 196.00 Sample 4 4.28 9.45 120.80 Sample 5 4.17 10.55 153.00 Sample 6 3.78 8.00 111.60 Sample 7 3.76 11.01 192.80 Sample 8 3.65 11.05 202.70 Sample 9 3.72 12.18 227.40

[0061] As shown in Table 2, using only the shampoo base group increased the hair bundle area ratio from 4.32% before use to 8.84%, but the volume improvement rate was only 104.6%.

[0062] After using shampoos containing functional compositions, the volume increase rate of hair bundle area was ≥111%. Among them, the test group using sample 9 showed a significant volume effect, with the hair bundle area increasing from 3.72% to 12.18% and the volume rate reaching as high as 227.4%.

[0063] Example 2: Consumer testing of shampoo base and products containing functional compositions

[0064] The shampoo base in Example 1 is Formula 1, and the shampoo in Sample 9 is Formula 2.

[0065] Formulas 1 and 2 were evaluated by consumers from three dimensions: fluffiness, oil control, and gentleness. The approval rating ranged from 0 to 7, from strong opposition to strong approval. The overall evaluation was calculated as the average approval rating divided by the maximum approval rating of 7. The overall satisfaction rating was the percentage of people who gave an approval rating of 5-7.

[0066] The results of a single trial, a 7-day trial, and a 28-day trial are shown in Tables 3, 4, and 5, respectively:

[0067] Table 3 Evaluation results after a single trial sample of the two formulations

[0068]

[0069] Table 4 Evaluation results of 7-day trial samples of the two formulations

[0070]

[0071] Table 5 Evaluation results of the two formulations after 28 days of trial samples

[0072]

[0073] As can be seen from the three tables above, Formula 2 is significantly more satisfactory than Formula 1 in terms of hair volume, oil control, and gentleness. This confirms that the formula composition of the present invention has better volume and oil control effects in practical applications, and will not lead to a decrease in volume or oily hair problems with long-term use.
