Description

Technical Field

[0001] The invention belongs to the technical field of cosmetics, and particularly relates to a silicone-free hair mask suitable for fine, soft and flat hair and a preparation method thereof. Background Art

[0002] According to the diameter of the hair, it can be divided into three categories: fine, medium and thick. The average fiber diameter of human hair is 29-125μm. The diameter of fine and soft hair is less than 0.06mm, and the hair shaft is thin and soft. Its elasticity and toughness are weaker than normal thick and thin hair. The hair follicles are small, and the hair is easy to break and flat. In addition to children's hair, some adult women also have fine and soft hair. The problems of fine and soft hair being easily damaged, greasy, flat, and sticking to the scalp have a certain impact on the lives of this part of the people, not only affecting the appearance, but also affecting the quality of life to a certain extent. Therefore, it is of great significance to solve the problem of fine and soft hair flattening.

[0003] In order to change the flatness of fine and soft hair, perming has become the first choice for most people who love beauty and fine and soft hair to change the shape of their hair, so as to achieve the effect of fluffy hair and increase visual volume. However, perming is one of the most common factors in hair damage. The perming process will directly damage the hair cuticles on the surface of the hair shaft. The hair cuticles that originally covered the hair shaft in a regular manner like scales will curl up, further leading to the loss of keratin in the hair, causing dry and frizzy hair.

[0004] In order to improve severe hair damage, hair masks have become the first choice for beauty lovers in hair care. Traditional hair masks have a strong conditioning effect. After people with fine and soft hair use them, although they have a certain repair effect on smoothing frizz, due to the accumulation of a large number of cationic surfactants and silicone oil substances, the hair becomes more greasy, flat, and less fluffy. While having a repairing effect, it also aggravates the problem of fine and soft hair flattening.

[0005] There are many types of hair mask products for repairing damaged hair, but there are only a handful of hair care products suitable for fine, soft and flat hair, and the choices for this part of consumers are limited. Traditional hair masks can often smooth the frizziness of hair to a certain extent, but cannot solve the problem of flat hair. A Chinese invention patent (CN115998635A) discloses a conditioner suitable for coarse, hard and dry hair and a preparation method thereof. The invention is mainly used for coarse, hard and dry hair, but there is no relevant report on hair care products specifically suitable for fine, soft and flat hair.

[0006] Therefore, there is an urgent need to develop a silicone-free hair product suitable for fine, soft, flat and collapsed hair. Summary of the invention

[0007] The present invention aims to solve at least one of the technical problems existing in the above-mentioned prior art. To this end, the present invention provides a silicone-free hair mask suitable for soft, fine and flat hair and a preparation method thereof. The silicone-free hair mask provided by the present invention significantly improves the combability of hair, repairs and strengthens hair strands at the same time, and enhances the volume of hair, thereby fundamentally improving the problem of easy flattening of soft and fine hair.

[0008] In the first aspect of the present invention, a silicone-free hair mask is provided. The components of the silicone-free hair mask include a cationic surfactant and a conditioner. The cationic surfactant includes an alkyl quaternary ammonium salt and a dimethylamine type, and the conditioner includes sapindus mukorossi pericarp extract, silybum marianum seed extract, niacinamide, hyaluronic acid, glutamic acid and serine.

[0009] Specifically, the sapindus mukorossi pericarp extract contains a large amount of natural sapindus saponins, which have medical values such as anti-inflammatory and antibacterial properties. When applied to daily chemical products, it has good foaming and detergency properties. In addition, the sapindus mukorossi pericarp extract has anti-inflammatory and oil-control effects in hair care, effectively inhibiting sebum secretion and improving the problem of easy oiliness of soft and fine hair.

[0010] Specifically, the silybum marianum seed extract contains rich flavonoid compounds and has strong antioxidant ability. Its antioxidant ability is 10 times that of vitamin E. This antioxidant property helps to protect the scalp from oxidative stress damage and reduce scalp aging. In addition, the silybum marianum seed extract contains anti-inflammatory substances, which can relieve the inflammatory reaction of oily and sensitive scalp, reduce redness and irritation, and reduce the sensitivity of the scalp.

[0011] Specifically, the combination of niacinamide and hyaluronic acid can help the scalp regulate the water-oil balance. Niacinamide, also known as nicotinamide or vitamin B3, has multiple effects such as moisturizing and repairing, antioxidant, and oil control. Niacinamide can reduce the production of fatty acids and triglycerides in sebum secreted by the skin, achieving the effect of controlling sebum secretion. And hyaluronic acid is a polysaccharide substance naturally present in the human body and is one of the substances with the strongest moisturizing ability known in nature. It can absorb and lock a large amount of water, and its moisturizing ability is 1000 times its weight. Therefore, it is known as the "natural moisturizing factor". It can not only replenish water to the scalp to achieve water-oil balance, but hyaluronic acid can also penetrate into hair strands and inject water into dry hair strands to restore luster.

[0012] Specifically, keratin is the most important protein in hair, accounting for more than 85% of the capillary structure. The amino acids in keratin interact with each other through hydrogen bonds, salt bonds and disulfide bonds to form its shape. In keratin, the amino acids with higher content are glutamic acid and serine. The present invention adds glutamic acid and serine exogenously, penetrates into the hair, supplements nutrition for the hair, increases the diameter of the hair shaft, and improves the support of fine and soft hair; at the same time, it repairs the lost keratin in the hair, plays a bionic repair role, forms a layer of hair shaft protective film, smoothes damaged and raised hair scales, and reduces hair static electricity and frizziness.

[0013] In some embodiments of the present invention, the alkyl quaternary ammonium salt includes at least one of behenyltrimethylammonium methyl sulfate, hexadecyltrimethylammonium chloride, and behenyltrimethylammonium chloride, and preferably a combination of any two or three.

[0014] In some embodiments of the present invention, the dimethylamines include at least one of stearamidopropyl dimethylamine, behenamidopropyl dimethylamine, and rapeseed amidopropyl dimethylamine, and preferably a combination of any two or three thereof.

[0015] Specifically, behenyltrimethylammonium methylsulfate is derived from behenic acid extracted from non-GMO rapeseed oil. Because its behenyl structure has unique direct adsorption and antistatic properties, it has excellent anti-tangling ability for hair and does not accumulate on the hair. In addition, it has a lower critical micelle concentration (CMC), which reduces the free amine content in the solution, so it is milder and reduces scalp irritation.

[0016] Specifically, the cationic surfactant is a compound of alkyl quaternary ammonium salt and dimethylamine, which reduces the deposition of cations and lightens the "gravity" of the hair. At the same time, it effectively neutralizes the negative charge of the hair, which can significantly reduce the static charge of the hair and reduce the damage of static electricity to the hair, thereby improving the condition of dry and frizzy hair and improving the combing properties of the hair.

[0056] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0057] (1) The silicone-free hair mask provided by the present invention, by combining alkyl quaternary ammonium salts with dimethylamine-based cationic surfactants, solves the problems of excessive conditioning and excessive deposition of traditional long carbon chain surfactants. While providing excellent wet and dry combing performance, it is light and fluffy after drying, effectively improving the problem of easy flattening of fine and soft hair. By combining extracts of Sapindus mukorossi pericarp with extracts of Silybum marianum seeds, it effectively nourishes the scalp, reduces the irritation of the hair mask to the scalp, and reduces the scalp's susceptibility to allergies. By combining niacinamide with hyaluronic acid, it effectively regulates the water-oil balance of the scalp, maintains the healthy barrier of the scalp, and enhances the long-lasting fluffiness of the hair strands. By combining glutamic acid and serine, it mimics the chemical composition structure of hair, plays a bionic repair role, penetrates into the hair strands, increases the hair strand diameter, and enhances the hair strand support force. Using the silicone-free hair mask provided by the present invention improves the combability of hair, repairs and strengthens the hair strands at the same time, and enhances the fluffiness of the hair, thus fundamentally improving the situation of easy flattening of fine and soft hair.

[0058] (2) The silicone-free hair mask provided by the present invention is not only suitable for people with fine, flat and collapsed hair, but also suitable for people with different hair qualities who pursue repair and a fluffy, smooth and compliant hair feel. Specific Embodiments

[0071] Comparative Examples 1-4

[0072] Comparative Examples 1-4 respectively provide a series of silicone-free hair masks with different component contents, and the specific component contents are shown in Table 3.

[0073] Table 3 Formulation of Silicone-Free Hair Masks in Comparative Examples 1-4

[0074]

[0075]

[0076] The difference between Comparative Example 1 and Example 1 is that dimethylamine is not added, and the content of behenyl trimethyl ammonium methyl sulfate is increased to 3%, and the other components, contents and preparation methods are the same as those in Example 1.

[0077] The difference between Comparative Example 2 and Example 1 is that silybum marianum seed extract is not added, and the content of sapindus mukorossi pericarp extract is increased to 0.7%, and the other components, contents and preparation methods are the same as those in Example 1.

[0078] The difference between Comparative Example 3 and Example 1 is that hyaluronic acid is not added, the content of niacinamide is increased to 0.1%, and the remaining components, contents and preparation method are the same as those in Example 1.

[0079] The difference between Comparative Example 4 and Example 1 is that glutamic acid and serine are not added, and the missing contents are distributed to the remaining conditioners. The remaining components, contents and preparation methods are the same as those in Example 1.

[0080] Comparative Examples 5-7

[0081] Comparative Examples 5-7 are all commercially available products, among which Comparative Example 5 is a commercially available silicone-free hair mask (Lv Anti-Hair Loss Mask), Comparative Example 6 is a commercially available silicone-free conditioner (Kérastase Essence Core Silk Luxury Protection Essence Cream), and Comparative Example 7 is a silicone-containing hair mask (Kérastase Radiant Color Luxury Protection Essence Cream).

[0082] Experiment 1: Combing force test

[0083] 1. Test product preparation: Select 15 bundles of moderately damaged real hair in vitro, soak the hair bundles completely in 5g / L sodium dodecyl sulfate solution, ultrasonically clean them for 30 minutes, rinse them with clean water and dry them naturally.

[0084] 2. Combing force measurement method:

[0085] 1) Use the dynamic combing instrument SK-7A to test the wet combing load integral value T0 of the hair bundle after washing with clean water wet , dry the hair naturally for 24 hours, and measure the integral value of the dry combing load T0 of the hair dry ;

[0086] 2) Take 3g of sample and apply it evenly on the hair bundle. After washing, measure the wet combing load integral value T1 of the hair bundle. wet After drying naturally for 24 hours, the dry combing load integral value T1 of the test hair bundle is dry The samples were selected from the products of Examples 1-8 and Comparative Examples 1-7.

[0087] 3. Criteria for judging combing power

[0088] 1) The calculation formula is as follows:

[0089]

[0090] Where: T0 dry : dry combing load integral value of the hair bundle before using the sample;

[0091] T0 wet : The integral value of wet combing load of the hair bundle before using the sample;

[0092] T1 dry : Dry combing load integral value of the hair bundle after using the sample;

[0093] T1 wet : The integral value of wet combing load after using the hair sample

[0094] 2) The integral value of load refers to the cumulative value of the load collected by the device within the corresponding time period; the larger the integral value of the load, the more difficult it is to comb the hair, and the less smooth the hair is; if the change rate < 0, it indicates that the sample has a smoothing effect on the hair bundle, and if the change rate ≥ 0, it indicates that the sample has no smoothing effect on the hair bundle.

[0095] 3) Significant difference: At the significance level of α = 0.05, when P > 0.05, there is no significant difference between the two; when P ≤ 0.05, there is a significant difference between the two, and when P ≤ 0.01, there is a highly significant difference between the two. In the statistical results of SPSS software, sig. = significance, which means "significance", that is, the P value.

[0096] 4) Result determination: After using the sample, the combability of dry and wet combing is significantly better than that before using the sample, or one dimension of the combability of dry and wet combing is significantly smaller and the other dimension has a significant difference in comparison (P ≤ 0.05).

[0097] 4. The test results of combability are shown in Table 4 and Table 5.

[0098] Table 4 Changes in the integral value of wet combing load of the hair bundle after using the sample

[0099]

[0100] Table 5 Changes in the integral value of dry combing load of the hair bundle after using the sample

[0101]

[0102]

[0103] It can be seen from the combability results in Table 4 and Table 5 that the improvement rates of dry and wet combing in Comparative Example 1 are significantly lower than those in Example 1, indicating that the compound use of alkyl quaternary ammonium salts and dimethylamine-based cationic surfactants can significantly improve the combing performance of the product and play a synergistic effect.

[0104] In addition, the improvement rates of dry and wet combing in Examples 1-8 are better than those of commercially available silicone-free products (Comparative Examples 5-6), and their combing effects are close to those of commercially available silicone-containing products, among which the combing improvement effect in Example 5 is the best.

[0105] Experiment 2: Fluffiness test

[0106] 1. Preparation of test samples: Prepare 16 groups of hair bundles and randomly divide them into a sample group and a blank group. The sample group uses the products of Examples 1-8 and Comparative Examples 1-7.

[0107] 2. The image acquisition instrument collects the initial images of the sample group and the blank group before cleaning.

[0108] 3. Blank group: Moisten the hair bundle to simulate the cleaning process, squeeze dry the hair bundle, then place it in an oven at (60 ± 1) °C, take it out after 30 min, and collect the hair bundle image.

[0109] 4. Sample group: Moisten the hair bundle to simulate the cleaning process, take 1.6 g of the sample and smear it evenly on the hair bundle, knead and absorb for 1 minute, then clean, squeeze dry the hair bundle, then place it in an oven at (60 ± 1) °C, take it out after 30 min, and collect the hair bundle image. After placing the cleaned and dried hair bundle at room temperature for 72 hours, collect the hair bundle image, and measure the hair bundle area for comparison between and within groups of hair bundles respectively.

[0110] 5. The test results are shown in Table 6.

[0111] Table 6 Statistical table of hair bundle areas of the sample group and the blank group

[0112]

[0113] It can be seen from the statistical results of the hair bundle areas in Table 6 that after cleaning and drying, compared with before cleaning, the change rates of the hair bundle areas of the commercially available silicone-free hair masks in Comparative Example 5 and the commercially available silicone-free hair conditioners in Comparative Example 6 are both greater than 50%, while the change rate of the hair bundle area of the commercially available silicone-containing hair mask in Comparative Example 7 is only 44.84%. And for the commercially available products in Comparative Examples 5 - 7, 72 h after using the products, the change rate of the hair bundle area is greater than -5%, among which Comparative Example 7 significantly decreased by -11.32% compared with 72 h ago, indicating that the hair fluffiness of the commercially available products is not persistent, especially the silicone-containing products. While the fluffiness and persistence of the products of Examples 1 - 8 of the present invention are better than those of the commercially available products. In addition, the hair bundle areas of the product in Comparative Example 3 after use and 72 h after use are both smaller than those of Example 1, and the difference between Comparative Example 3 and Example 1 is that hyaluronic acid is not added, indicating that in the silicone-free hair mask product of the present invention, the compounding of niacinamide and hyaluronic acid has a synergistic effect, can more effectively control the scalp oil secretion, and improve the hair fluffiness and persistence from the root.

[0114] Experiment 3: Tensile strength and hair diameter test

[0115] 1. Preparation of test samples: Prepare multiple bundles of grouped hair bundles, randomly divided into a blank group and an experimental group; the experimental group uses the products of Examples 1 - 8 and Comparative Examples 1 - 7.

[0116] 2. Tensile strength test method: Use a Dia-stron MTT 175 multi-functional hair tester to measure the stress when the hair filaments in the blank group are broken, and record the data as F (gmf).

[0117] 3. Blank group: Wet the hair bundles to simulate the cleaning process, place them in an oven at (60±1)°C, take them out after 30 minutes, and measure the tensile strength and diameter. Repeat the above operations 6 times and 12 times, and measure the tensile strength and diameter again.

[0118] 4. Experimental group: Wet the hair bundles to simulate the cleaning process, take 3.2 g of the product and apply it evenly on the hair bundles, knead and absorb for 1 minute, then wash, place them in an oven at (60±1)°C, take them out after 30 minutes, and measure the tensile strength and diameter. Repeat the above operations 6 times and 12 times, and then measure the tensile strength and diameter again. Compared with the blank group, if the tensile strength of the experimental group increases significantly, it indicates that the product has the effect of preventing hair breakage.

[0119] 5. The test results are shown in Table 7.

[0120] Table 7 Statistical table of tensile strength and diameter of the blank group and the experimental group

[0121]

[0122]

[0123] As can be seen from Table 7, the tensile strength of Examples 1-8 is relatively good, which is close to that of the silicone-containing product in Comparative Example 7. The difference between Comparative Example 4 and Example 1 is that the glutamate and serine composition is not contained, resulting in a significant decrease in the tensile strength of Comparative Example 4 compared with Example 1, indicating that small molecule glutamate and serine can effectively penetrate into the hair strands, supplement the hair nutrition, improve the hair strength, and effectively prevent hair breakage.

[0124] Experiment 4: Conduct a consumer test and evaluation on the use effect of the hair mask

[0125] Using the public opinion poll scoring method, recruit 195 volunteers with damaged, soft, flat and collapsed hair quality who have experienced perming and dyeing, aged 18-45 years old, divided into 13 groups, with 15 people in each group, and use the samples of the above Examples 1-8 and Comparative Examples 1-7 respectively. The usage method is to uniformly clean the head with a silicone-free shampoo and then use the above samples. The usage frequency is once every 2 days, and continue to use for 14 days. During the test period, no other hair care products are used. In the form of a questionnaire survey, the volunteers score according to their own trial feelings. The total score is 5 points: 1 point is poor, 2 points is relatively poor, 3 points is average, 4 points is good, and 5 points is very good. The average score is taken, and the results are shown in Table 8.

[0126] Table 8 Score results of the population test and evaluation on the use effect of the hair mask

[0127]

[0128]

[0129] The test data of the volunteer population in Table 8 shows that, from the satisfaction results of Comparative Example 1 and Example 1, consumers are more satisfied with the use effect of the hair mask of the system of alkyl quaternary ammonium salt compounded with dimethylamine-based cationic surfactant, especially the softness, fluffiness, freshness of dry hair and the continuous fluffiness effect for 24 hours. The difference between Comparative Example 2 and Example 1 is that it does not contain silybum marianum seed extract. The overall satisfaction of consumers with Example 1 is significantly higher than that of Comparative Example 2, indicating that the compounding of sapindus mukorossi pericarp extract and silybum marianum seed extract has a synergistic effect, which can effectively improve the scalp condition and enhance the use satisfaction of consumers.

[0130] In summary, when the alkyl quaternary ammonium salt, dimethylamine, sapindus mukorossi pericarp extract, silybum marianum seed extract, niacinamide, hyaluronic acid, glutamic acid and serine are compounded together in the present invention, consumers have the highest satisfaction with the smoothness of the use effect of the hair mask and the repair effect on hair. Among them, the compounding of sapindus mukorossi pericarp extract and silybum marianum seed extract can effectively soothe the scalp and reduce the sensitivity of oily and sensitive scalps, while niacinamide and hyaluronic acid effectively regulate the water-oil balance, maintain the health of the scalp barrier from the root, reduce scalp oiliness, and enhance the lasting fluffiness of hair strands. In addition, the externally supplemented glutamic acid and serine, which mimic the components of hair keratin, effectively moisten damaged hair quality, improve the dry state of hair, increase hair diameter, enhance hair strand support force, and effectively solve the problem of easy oiliness and flattening of the hair of people with soft, thin and flat hair quality.
