Description

Technical Field

[0001] This application relates to the field of cosmetic loose powder technology, and more specifically, it relates to a hair volumizing powder and its preparation method. Background Technology

[0002] Volumizing powder is a type of loose powder product that makes hair fluffy. Men can use it to create textured hairstyles, while women can use it to create voluminous hairstyles, fluffy curls, and more. It is extremely convenient to use; simply pour a little volumizing powder onto the top of your head and gently massage it into your scalp with your fingers to distribute the powder evenly over your hair. It is especially suitable for people who need to wash their hair every day, or those who don't have time to wash their hair for important occasions. A simple application can make hair look thick, fluffy, and as if it has been washed.

[0003] When using volumizing powder, oily hair can affect the longevity of the hairstyle. As we all know, sebaceous glands are the scalp's oil reservoir, constantly synthesizing and transporting oil to the scalp. When the external temperature is high, excessive sebum secretion from the sebaceous glands manifests as oily hair, causing it to clump. Therefore, volumizing powder typically uses various oil-absorbing ingredients to counteract the oil secretion from the sebaceous glands, thus ensuring the longevity and stability of the voluminous hairstyle. However, multiple oil-absorbing ingredients can easily lead to excessive oil absorption by the scalp, resulting in relatively high water content in the scalp's stratum corneum and damage to the sebum film. This weakens the scalp's skin barrier function, making it easier for harmful external factors to penetrate the skin, ultimately altering hair quality and significantly impacting the stability and longevity of the hairstyle.

[0004] Therefore, there is an urgent need to propose a solution to address the aforementioned technical problems. Summary of the Invention

[0005] In order to maintain the scalp's oil-water balance during the application of volumizing powder and to bring a more stable and long-lasting styling effect, this application provides a loose powder product using volumizing powder and its preparation method.

[0006] In the first aspect, this application provides a bouncy hair powder, which adopts the following technical solution:

[0007] A volumizing powder for hair, made from the following ingredients in parts by weight:

[0008] 40-55 parts of aluminum octenyl succinate starch;

[0009] 10-20 parts silica;

[0010] 5-15 parts of methyl methacrylate crosspolymer;

[0011] 4-6 parts of VP / VA copolymer;

[0012] 2-4 parts moisturizer;

[0013] Preservative: 0.6-0.8 parts;

[0014] 0.1-0.3 parts of the active composition;

[0015] Inositol 0.3-0.5 parts;

[0016] Nicotinamide 0.1-0.3 parts.

[0017] By employing the above technical solutions, the VP / VA copolymer exhibits strong film-forming ability, making it an excellent hair styling agent capable of achieving hair shaping. Aluminum octenyl succinate has good dispersibility and strong adsorption, effectively absorbing excess sebum secreted by the sebaceous glands; silica has good adhesion, effectively adhering to the hair shaft and absorbing scalp oil; methyl methacrylate crosspolymer has outstanding oil-absorbing effect and can stably combine with other oil-absorbing and oil-controlling ingredients, exerting excellent effects; the combination of aluminum octenyl succinate, silica, and methyl methacrylate crosspolymer to form an oil-absorbing and oil-controlling system can effectively address situations with excessive hair oil production. The combination of inositol and polyamide not only regulates sebaceous gland secretion, relatively reducing hair oil, but also effectively controls the water content of the scalp stratum corneum when it is relatively high, thereby maintaining the scalp's water-oil balance. Meanwhile, the combined use of aluminum octenyl succinate, silica, methyl methacrylate crosspolymer, inositol, and niacinamide not only results in outstanding oil absorption and control but also prevents excessive oil absorption. It helps maintain a relatively stable water-oil balance on the scalp, and the sebum film is not easily damaged. The skin barrier function of the scalp remains stable, and the hair quality does not change significantly. As a result, the volumizing powder provides a stable and long-lasting styling effect after application.

[0018] Preferably, the raw materials of the hair volumizing powder also contain 1.6-2.8 parts by weight of a regulating agent, which is composed of sodium cocoyl glutamate and sea salt, and the weight ratio of sodium cocoyl glutamate to sea salt is (1.5-3):1.

[0019] By employing the above-mentioned technical solutions, sea salt can stimulate the excretion of water from the scalp's stratum corneum; while sodium cocoyl glutamate can effectively moisturize and act as a water barrier in the skin, effectively preventing excessive water loss; when sodium cocoyl glutamate and sea salt are used as a regulating agent in a specific weight ratio, the two can promote and inhibit each other, thus playing a prominent and excellent water regulation role when excessive oil absorption and relatively high water content in the scalp's stratum corneum occur, maintaining the scalp's water-oil balance, further improving the application effect of hair volumizing powder, and making the user's hair style more stable and long-lasting.

[0020] Preferably, the weight ratio of sodium cocoyl glutamate to sea salt is 2:1.

[0021] By adopting the above technical solution, the synergistic effect of sodium cocoyl glutamate and sea salt in the above weight ratio is better when applied. It can more quickly regulate the scalp's water-oil balance, thus having less impact on hair quality and making hair styling more stable and lasting. As a result, the hair volumizing powder has a better application effect.

[0022] Preferably, the raw materials of the hair volumizing powder further include 0.8-2 parts by weight of hyaluronic acid-modified carbon nanotubes, and the hyaluronic acid-modified carbon nanotubes are prepared by the following steps:

[0023] S1. Take a hyaluronic acid solution with a concentration of 0.2-0.5%, mix the multi-walled carbon nanotube raw material and the hyaluronic acid solution at a weight ratio of (0.3-0.5):1, and after ultrasonic dispersion, obtain the modified mixed stock solution;

[0024] S2. Add calcium chloride to the ethanol solution until the calcium chloride no longer dissolves to obtain a coagulated solution; then squeeze the modified mixed solution into the coagulated solution to obtain a solidified product; finally, wash and dry the solidified product, and polish it to obtain hyaluronic acid modified carbon nanotubes.

[0025] By employing the above-mentioned technical solution, the use of hyaluronic acid-modified carbon nanotubes serves two main purposes. First, it acts as a support structure, working in conjunction with VP / VA copolymers to achieve superior styling results through the combined effect of the membrane and the support structure, resulting in more stable and longer-lasting hair styling. Second, utilizing the cell affinity and cell penetration properties of hyaluronic acid, one end of the carbon nanotube can be introduced into the stratum corneum of the skin. Through the adsorption of water molecules by hyaluronic acid and the ducting effect of the carbon nanotube, water in the stratum corneum can be rapidly drained. The effect of hyaluronic acid-modified carbon nanotubes is particularly noticeable when excessive oil absorption occurs. Therefore, the application of hyaluronic acid-modified carbon nanotubes has an excellent effect on maintaining the scalp's oil-water balance, significantly improving the stability and longevity of hair styling when using hair volumizing powder.

[0026] Preferably, the hyaluronic acid raw material in the hyaluronic acid solution is composed of small molecule hyaluronic acid and medium molecule hyaluronic acid in a weight ratio of (1.3-1.9):1.

[0027] By adopting the above technical solution, the molecular and medium molecular weight hyaluronic acid in the above weight ratio, after reacting with multi-walled carbon nanotube raw materials, can form a two-level skin-compatible hyaluronic acid structure at the end of the multi-walled carbon nanotubes. This allows the hyaluronic acid-modified carbon nanotubes to not only act more easily on the scalp stratum corneum after application, but also to be suitable for the scalp skin of more users, with stronger adaptability. Thus, the resulting hair volumizing powder has a more superior application quality.

[0028] Preferably, the weight ratio of the small molecule hyaluronic acid to the medium molecule hyaluronic acid is 1.6:1.

[0029] By adopting the above technical solution, the hyaluronic acid modified carbon nanotubes obtained after applying the above weight ratio of small molecule hyaluronic acid and medium molecule hyaluronic acid have the best corresponding effect. The resulting hair volumizing powder can maintain the water-oil balance of the user's scalp and skin, and bring a more stable and long-lasting styling effect.

[0030] Preferably, the emollient is one or a combination of several of squalane, ginger root oil, shea butter and coconut oil.

[0031] By adopting the above technical solutions, the above-mentioned types of moisturizers have a strong skin-friendly feel, can fully combine with other component raw materials, can improve the texture of hair volumizing powder, and can greatly reduce the floating of powder during the use of hair volumizing powder.

[0032] Preferably, the active composition is a combination of one or more of the following: Polygonum multiflorum extract, black sesame extract, Salvia miltiorrhiza root extract, Sophora flavescens extract, and Rehmannia glutinosa extract.

[0033] By adopting the above technical solution, the use of the above active composition can play an oxidizing and repairing role on hair, and can reduce the damage to hair caused by hair volumizing powder to a certain extent, and improve its long-term stable effect.

[0034] Preferably, the preservative is one or a combination of several of phenoxyethanol, octyl glycol, benzyl alcohol, and methylparaben.

[0035] By adopting the above technical solutions, the above-mentioned preservatives can be fully combined with other raw materials and inhibit the growth and reproduction of microorganisms, thus giving the bouncy powder a longer shelf life.

[0036] Secondly, this application provides a method for preparing hair-plumping powder, which adopts the following technical solution:

[0037] A method for preparing hair-volumizing powder includes the following steps:

[0038] (1) Prepare raw materials containing aluminum octenyl succinate, silica, methyl methacrylate crosspolymer, VP / VA copolymer, emollient, preservative, active composition, inositol and nicotinamide according to the formula ratio;

[0039] (2) Stir the starch octenyl succinate aluminum and silica in step (1) at 2600-2900 r / min for 50-70s until they are evenly mixed. Then add methyl methacrylate crosslinking polymer and VP / VA copolymer and stir at 800-900 r / min for 25-35s to obtain a mixture.

[0040] (3) Take 10%-30% of the total amount of the mixture in step (2), add emollient and preservative, mix evenly to obtain the first premix; at the same time, take 10%-30% of the total amount of the mixture, add active composition, mix evenly to obtain the second premix; (4) Add the first premix and the second premix in step (3) to the remaining mixture, then add inositol and nicotinamide, stir and mix evenly to obtain hair volumizing powder.

[0041] By adopting the above technical solution, the preparation method is simple to operate and suitable for large-scale industrial production. Adding each component raw material in stages facilitates quality control during the process. At the same time, by first mixing a portion of the starch octenyl succinate aluminum, silica, methyl methacrylate crosspolymer, and VP / VA copolymer with emollients, preservatives, and active ingredients, and then adding the remaining starch octenyl succinate aluminum, silica, methyl methacrylate crosspolymer, VP / VA copolymer, as well as inositol and nicotinamide, the components can be fully combined and interact, resulting in a high-quality and stable product.

[0042] In summary, this application has the following beneficial effects:

[0043] 1. Because this application combines aluminum octenyl succinate, silica, methyl methacrylate crosspolymer, inositol, and nicotinamide in its volumizing powder product, it not only has outstanding oil absorption and control effects but also avoids excessive oil absorption. It maintains a relatively stable water-oil balance on the scalp, preventing damage to the scalp's sebum film and ensuring a stable skin barrier. This results in a stable and long-lasting styling effect while maintaining hair quality stability. 2. This application adds a regulating agent composed of sodium cocoyl glutamate and sea salt in a specific weight ratio. The mutual promotion and inhibition between the two agents achieve a balanced effect. This allows for excellent regulation when excessive oil absorption occurs and the scalp's stratum corneum moisture content is relatively high, maintaining the scalp's water-oil balance. Consequently, the volumizing powder performs even better in maintaining the long-lasting and stable styling of the user's hair after application.

[0044] 3. This application, through the addition of specially prepared hyaluronic acid modified carbon nanotubes, not only makes hair styling more stable and lasting, but also, while maintaining the excellent oil absorption and control effect of hair volumizing powder, has an excellent effect on maintaining the water-oil balance of the scalp, thereby greatly improving the stable and lasting styling effect of hair volumizing powder on the user's hair.

[0169] Performance testing test samples: The hair volumizing powder obtained in Examples 1-31 was used as test samples 1-31, and the hair volumizing powder obtained in Comparative Examples 1-9 was used as control samples 1-9.

[0170] Experimental Method: Two hundred volunteers were selected and randomly divided into 40 groups of 5 people each. Before the test, volunteers were required to have not washed their hair or used any hair products for 72 hours under normal conditions, allowing their hair to remain in its natural state. Then, the forty groups of volunteers used the hair volumizing powder from test samples 1-31 and control samples 1-9 respectively, and the following tests were conducted in a room with a constant temperature of 23±2℃ and a relative humidity of 50±10% as follows:

[0171] (1) Oil absorption effect test: Forty groups of volunteers used hair volumizing powder at a dosage of 0.85g / person. After 6 hours, they used oil-absorbing paper to absorb the oil in their hair and measured the area of ​​the oil on the entire oil-absorbing paper. The percentage of oil absorption area for each group of five people was scored according to the following scoring criteria, and the average value was recorded in Table 2.

[0172] Oil absorption area percentage (%) Scoring criteria (points) ＞70 0-3 (inclusive) 50-70 (inclusive) 3-5 (inclusive) 30-50 (inclusive) 5-8 (inclusive) ≤30 8-10

[0173] (2) Water-oil balance test: The normal water-oil ratio of the skin is 30-50%. If it is below 30%, the skin may be dry, which means that the skin is dehydrated; if it is above 50%, it means that there is excessive oil secretion. Based on the oil absorption effect test, the water-oil ratio of the scalp of forty groups of volunteers was measured using a skin water-oil analyzer. Since the volunteers are from different groups of individuals, there are differences in their own water-oil balance ratios. Therefore, when recording the test results, if the results are within the above range, it is recorded as water-oil balance has been achieved; if they are outside the above range, it is recorded as water-oil balance has not been achieved. If all volunteers in each group achieve the balance, it is recorded as all volunteers have achieved the balance. If there are cases where the balance is not achieved, the corresponding number of people is recorded.

[0174] (3) Styling effect test: Forty groups of volunteers used hair volumizing powder at a dosage of 0.85g / person. After 8 hours, the fluffiness and adhesion of the volunteers' hair were scored. The scoring criteria are as follows: The average score of each group of volunteers was recorded in Table 2, corresponding to test samples 1-31 and control samples 1-9.

[0175] hair condition Scoring criteria (points) Poor fluffiness and high stickiness 0-2 (inclusive) Poor fluffiness and high stickiness 2-4 (inclusive) Average fluffiness and adhesion 4-6 (inclusive) High loftiness and low stickiness 6-8 (inclusive) High loftiness and low stickiness 8-10

[0176] Table 1 shows the test results of test samples 1-31 and control samples 1-9.

[0179] Based on Examples 1-10 and Comparative Examples 1-3, and referring to Table 2, it can be seen that when using an oil-absorbing and oil-controlling system composed of aluminum octenyl succinate, silica, and methyl methacrylate cross-linked polymer, the combined use of inositol and niacinamide allows the hair volumizing powder to maintain excellent oil-absorbing and oil-controlling effects while keeping the scalp's oil-water balance and providing long-lasting style stability. However, without the use of inositol and niacinamide, or with only one of them, while the stable oil-absorbing and oil-controlling effect is not affected, an imbalance of oil and water occurs, and the style stability is relatively poor. Furthermore, based on Comparative Examples 4-9 and Table 2, it can be seen that using any one or two of aluminum octenyl succinate, silica, and methyl methacrylate cross-linked polymer alone results in a significantly inferior oil-absorbing and oil-controlling effect compared to the combination of all three ingredients, and has a substantial negative impact on maintaining the scalp's oil-water balance and the long-lasting stability of the user's hair style.

[0180] As can be seen from Examples 1 and 11-16, and in conjunction with Table 2, the addition of a conditioning agent composed of sodium cocoyl glutamate and sea salt in a weight ratio of (1.5-3):1 significantly improves the oil absorption and styling effect of volumizing powder. The improvement effect is particularly pronounced when the weight ratio of sodium cocoyl glutamate to sea salt is 2:1. Further, as can be seen from Examples 17-18 and Table 2, the improvement effect is significantly reduced when the weight ratio of sodium cocoyl glutamate to sea salt exceeds the above range. Furthermore, as can be seen from Examples 19-20 and Table 2, the effect of using either sodium cocoyl glutamate or sea salt alone is far less effective than the combined effect of the two. Therefore, applying a conditioning agent composed of sodium cocoyl glutamate and sea salt in a specific ratio to volumizing powder can provide a stable improvement in both oil absorption and styling effect.

[0181] Combining Examples 1 and 21-25 with Table 2, it can be seen that adding hyaluronic acid-modified carbon nanotubes to bouncy hair powder significantly improves its oil absorption and styling effects. Furthermore, combining Examples 26-27 with Table 2, it can be seen that the hyaluronic acid raw material in the hyaluronic acid solution is composed of small-molecule hyaluronic acid and medium-molecule hyaluronic acid in a weight ratio of (1.3-1.9):1, which enables the resulting hyaluronic acid-modified carbon nanotubes to exhibit excellent and stable effects during application. Specifically, when the weight ratio of small-molecule hyaluronic acid to medium-molecule hyaluronic acid is 1.6:1, the improvement effect of hyaluronic acid-modified carbon nanotubes is particularly excellent. Combining Examples 28-29 with Table 2, it can be seen that when the weight ratio of small-molecule hyaluronic acid to medium-molecule hyaluronic acid exceeds the above range, the improvement effect is significantly reduced. Furthermore, referring to Examples 30-31 and Table 2, it can be seen that if the hyaluronic acid raw material in the hyaluronic acid solution contains only one of small molecule hyaluronic acid and medium molecule hyaluronic acid, the resulting hyaluronic acid modified carbon nanotubes will show a significant loss in the improvement of oil absorption and shaping effects when applied.
