Description

Technical Field

[0001] The invention belongs to the technical field of cosmetics, and particularly relates to a shampoo with a three-layer appearance and a preparation method thereof. Background Art

[0002] At present, the mainstream shampoo products in the market include shampoo, cleansing cream, etc., and shampoo is widely used. However, with the improvement of people's living standards, the requirements for shampoo products have also increased. It is not only limited to the cleaning function, but more of a multi-effect product demand. The high standards of both have prompted the innovation of shampoo products. Most of the existing shampoos are based on water-based systems, and then matched with surfactants, conditioners, oils, fragrances and other ingredients. The product appearance is mainly transparent and pearlescent, and they are all uniform systems. A few double-layer shampoo bubble products are generally water-oil two-phase stratification, which is essentially a water-based system. In order to break the bottleneck of the single shampoo product system, merchants have innovated and developed shampoo, focusing on the concept of oil-based hair care. The transparent shampoo on sale in the market is basically single-phase, and there are problems such as low foam volume and dry hair after use. Consumers have low acceptance, so the product sales are not good. There is little research and development on oil-based cleaning and care products, especially shampoo products. Therefore, how to increase the foam volume of shampoo and improve the combing of hair after use is a technical problem to be solved in this field. Summary of the invention

[0003] 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 shampoo with a three-layer appearance and a preparation method thereof. The shampoo of the present invention has a novel three-layer appearance, foams quickly, has rich foam, makes wet hair smooth and not dry, and makes dry hair soft and refreshing.

[0004] The first aspect of the present invention provides a shampoo with a three-layer appearance, wherein the shampoo with a three-layer appearance comprises components: laureth sulfate MIPA salt, nonionic surfactant, polyol, linear polysiloxane, vegetable oil, excluding water; the vegetable oil comprises coconut oil, macadamia seed oil and jojoba seed oil.

[0005] It is to be understood that "excluding water" in the present invention means that no separate water raw material is added to the shampoo of the present invention, and a small amount of water contained in the raw material components used in the present invention is allowed to exist.

[0006] In some embodiments of the present invention, the shampoo with a three-layer appearance includes the following components, measured by mass percentage: 25-35% lauryl polyether sulfate MIPA salt, 1-10% nonionic surfactant, 4-25% polyol, 10-20% linear polysiloxane, and 15-25% vegetable oil.

[0007] In some embodiments of the present invention, the nonionic surfactant includes at least one of lauryl polyether-3, coconut amide MEA, PEG-80 sorbitan laurate, sorbitan polyether-30 tetraoleate, and PEG-7 glyceryl cocoate.

[0008] In some embodiments of the present invention, the nonionic surfactant is lauryl polyether-3.

[0009] In some embodiments of the present invention, the polyol includes propylene glycol and / or glycerol.

[0010] In some embodiments of the present invention, the polyol includes propylene glycol and glycerol.

[0011] In some embodiments of the present invention, the mass ratio of propylene glycol to glycerol is 1:(0.4 - 1.5).

[0012] In some embodiments of the present invention, the linear polysiloxane includes polydimethylsiloxane with a viscosity of 100 cps and / or 350 cps at 25°C.

[0013] In some embodiments of the present invention, the linear polysiloxane includes polydimethylsiloxane with a viscosity of 100 cps and 350 cps at 25°C.

[0014] In some embodiments of the present invention, the mass ratio of polydimethylsiloxane with a viscosity of 100 cps to polydimethylsiloxane with a viscosity of 350 cps is 1:(1 - 2).

[0015] In some embodiments of the present invention, the mass ratio of coconut oil, macadamia nut oil, and jojoba oil is (1 - 3):(1 - 3):(1 - 3).

[0016] In some embodiments of the present invention, the mass ratio of coconut oil, macadamia nut oil, and jojoba oil is 1:(2 - 3):1.

[0017] In some embodiments of the present invention, the hair oil having a three-layer appearance further includes excipients acceptable in cosmetics.

[0018] In some embodiments of the present invention, the mass content of the excipients in the hair oil is 0.1 - 2%.

[0019] In some embodiments of the present invention, the excipients include antioxidants and / or fragrances.

[0020] In a second aspect of the present invention, there is provided a method for preparing the hair oil having a three-layer appearance according to the first aspect of the present invention, comprising the following steps:

[0021] Mix the lauryl polyether sulfate MIPA salt, nonionic surfactant, polyol, linear polysiloxane, and vegetable oil to obtain the hair oil having a three-layer appearance.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] The hair oil having a three-layer appearance provided by the present invention is an anhydrous system. Compared with traditional single-layer hair oils, it has a novel appearance, enhancing the sense of pleasure in use, and the amount of foam is comparable to that of liquid shampoos in the sulfate system, solving the problems of difficult foaming, less foam amount, dry and frizzy hair during wet hair washing of single-layer hair oils, and having both aesthetic and texture. In addition, due to the special hair oil system, traditional hair conditioners cannot be added to the product, resulting in problems such as dry and frizzy hair in single-phase hair oils on the market. To address this difficulty, the present invention particularly adds linear polysiloxane, compounded with polyols and vegetable oils, significantly improving the smoothness of wet hair, and can nourish and repair hair strands while washing, enhancing the gloss of hair, achieving the effect of two-in-one hair washing and care. Description of the Drawings

[0024] Figure 1 It is a sample diagram of the hair oil prepared in Example 1 of the present invention. Detailed Description of the Invention

[0025] The content of the present invention will be further described in detail through specific examples below. The raw materials, reagents or devices used in the examples can be obtained from conventional commercial channels or can be obtained by existing technical methods without special instructions. Unless otherwise specified, the test or measurement methods are conventional methods in the art.

[0026] In the examples of the present invention, the lauryl polyether sulfate MIPA salt was purchased from Sasol (China) Chemical Co., Ltd., lauryl polyether-3 was purchased from Clariant Chemical Technology (Shanghai) Co., Ltd., PEG-80 sorbitan laurate was purchased from Croda Singapore Pte Ltd, cocamide MEA was purchased from BASF (China) Co., Ltd., sorbitan polyether-30 tetraoleate was purchased from the Chiba Factory of Toho Chemical Industry Co., Ltd., PEG-7 glyceryl cocoate was purchased from BASF (China) Co., Ltd., propylene glycol was purchased from Guangzhou Hengtuo Trading Co., Ltd., glycerol was purchased from Guangzhou Jahwa Chemical Co., Ltd., tocopheryl acetate was purchased from DSM Nutritional Products Ltd., macadamia (MACADAMIA TERNIFOLIA) seed oil was purchased from Shanghai Xinyan, coconut (COCOS NUCIFERA) oil was purchased from SOPHIM S.A.S., jojoba (SIMMONDSIA CHINENSIS) seed oil was purchased from Vantage Specialty Chemicals, Inc, and the fragrance was purchased from Givaudan Flavors & Fragrances (Shanghai) Co., Ltd.

[0027] It is understood that the raw materials used in the present invention are not limited to the above-mentioned purchase channels.

[0028] Examples 1 - 7

[0029] Examples 1 - 7 respectively provide a hair oil with a three - layer appearance, and the specific formula is shown in Table 1; the unit is mass percentage.

[0030] Table 1 Hair Oil Formula

[0031]

[0032]

[0033] The preparation method of the hair oil in Examples 1 - 7 includes the following steps:

[0034] Mix the raw materials of Phase A, Phase B, and Phase C, stir evenly, and then sequentially add the raw materials of Phase D, Phase E, and Phase F, and mix evenly.

[0035] The appearance of the hair oil sample prepared in Example 1 is as Figure 1 shown, having an upper, middle, and lower three - layer appearance.

[0036] The hair oils prepared in Examples 2 - 7 also have a three - layer appearance, which will not be elaborated with additional drawings here.

[0037] Comparative Examples 1 - 8

[0038] Comparative Examples 1 - 8 respectively provide a hair oil with a three - layer appearance, and the specific formula is shown in Table 2; the unit is mass percentage.

[0039] Table 2 Hair Oil Formula

[0040]

[0041]

[0042] The preparation method of the hair oil in Comparative Examples 1 - 8 is the same as that in the examples.

[0043] The hair oils prepared in Comparative Example 6 and Comparative Example 7 both have a two - layer appearance, and the hair oils prepared in the remaining comparative examples all have a three - layer appearance. It can be seen that without the polyol and linear polysiloxane in the present invention, a three - layer appearance cannot be formed.

[0044] Experimental Example 1 Foaming Ability Test

[0045] The hair oils prepared in the above Examples 1-7 and Comparative Examples 1-7, as well as the commercially available sample, were used as test samples and tested using a Ross-Miles foam meter. The test results are shown in Table 3. Among them, the commercially available sample is the Miaocui hair oil (scent: Shan) produced by Guangdong Zhenbao Health Daily Necessities Technology Co., Ltd., and the record number is Guangdong G Makeup Net Preparation No. 2022171133.

[0046] Table 3 Test Results of Foam Height

[0047]

[0048]

[0049] From the results in Table 3, it can be seen that the hair oils with a three-layer appearance can be prepared in Examples 1-7 of the present invention, and their foam heights are far higher than those of the commercially available sample, indicating that the hair oil provided by the present invention can significantly improve the problem of difficult foaming of traditional hair oils. Compared with Example 1, the foam height decreases with the increase of the glycerol content in Examples 2-3. Compared with Example 1, the foam heights of Examples 6-7 and Comparative Examples 3-5 show that macadamia ternifolia seed oil has the least influence on foam. Compared with Example 1, the foam heights of Comparative Examples 1-2 illustrate the necessity of MIPA lauryl polyether sulfate, and simply adding a large amount of non-ionic surfactants cannot foam normally. Compared with Example 1, the foam heights of Examples 4-5 show that the foam boosting ability of non-ionic surfactants PEG-80 sorbitan laurate and coconut oil amide MEA is poor.

[0050] Experimental Example 2 Combing Property Test

[0051] The hair oils prepared in the above Examples 1-7, Comparative Examples 1-5, 8, as well as the commercially available sample, were used as test samples, and a hair softness tester SK-3A was used to test the combing property of each sample. The commercially available sample is the same as in Experimental Example 1.

[0052] Its working principle is: through a constant pressure and automatic operation, a process of sensory quantification is achieved. The combing property data is the processed result, and the lower the value, the better the combing property and the softer the hair. The hair softness detector used in this experiment mainly consists of components such as a shower head, a displacement meter, a loading unit, and an electrostatic sensor.

[0053] Test method: Fifteen identical hair bundles prepared were placed on a dynamic combing property tester. The dry hair bundle without applying any hair care products was used as a blank control. The test sample was applied to the hair bundle to evaluate the influence on the combing property of the hair. The specific test results are shown in Table 4 (Comparative Examples 6-7 do not meet the requirements with a two-layer appearance, and no combing property data is provided here).

[0054] Table 4 Test Results of Hair Bundle Combing Property

[0055] Sample Name Baseline Wet Comb Blank Control 1.00 1.00 Example 1 1.00 0.55 Example 2 1.00 0.65 Example 3 1.00 0.63 Example 4 1.00 0.60 Example 5 1.00 0.58 Example 6 1.00 0.60 Example 7 1.00 0.62 Comparative Example 1 1.00 0.90 Comparative Example 2 1.00 0.90 Comparative Example 3 1.00 0.73 Comparative Example 4 1.00 0.65 Comparative Example 5 1.00 0.70 Comparative Example 8 1.00 0.62 Commercially Available Sample 1.00 0.90

[0056] As can be seen from the results in Table 4, after the shampoo oils prepared in Examples 1-7 were used to wash the hair bundles and then rinsed with water, the wet combability data were all lower than those of the blank control and the commercial samples. This indicates that the shampoo oil prepared by the present invention can significantly improve the problem of dryness of wet hair. Compared with Example 1, after the shampoo oils prepared in Comparative Examples 3-5 and Comparative Example 8 were used to wash the hair bundles and then rinsed with water, the decrease in wet combing data was significantly lower than that in Example 1; this combability result shows that the three vegetable oils, coconut oil, macadamia seed oil, and jojoba seed oil, have a synergistic effect on the wet hair combability when combined with each other. Compared with Example 1, Examples 6-7 show that macadamia (MACADAMIA TERNIFOLIA) seed oil has the best improvement effect on wet combing. Compared with Example 1, the wet hair data of Examples 2-3 are slightly worse, indicating that appropriately increasing the content of linear polysiloxane can improve the wet hair combability. Compared with Example 1, the wet combability data of Comparative Examples 1-2 are much lower than those of Example 1 because Comparative Examples 1-2 did not add the main surfactant MIPA lauryl polyether sulfate, resulting in poor foaming ability and cleaning ability, and excessive residues of polyols and linear polysiloxane on the hair bundles during wet rinsing, causing stickiness and increasing resistance. Compared with Example 1, the wet combability of Examples 4-5 is slightly worse, indicating that the non-ionic surfactant lauryl polyether-3 has a more synergistic effect on the wet hair combability.

[0057] Experimental Example 3 Hair Glossiness Test

[0058] The glossiness of the hair bundles was tested using a skin glossiness test probe, and the hair bundles were grouped according to the corresponding data. An appropriate amount of shampoo oil was applied to the hair bundles, and then scrubbed, rinsed, and dried. The glossiness of the hair before using the shampoo oil, the glossiness immediately after using the shampoo oil, and the glossiness after 1 h were tested respectively. Then, the percentage increase in glossiness immediately after using the shampoo oil and the glossiness after 1 h compared with the glossiness of the hair before using the shampoo oil was calculated respectively. The test results are shown in Table 5 (Comparative Examples 1-2 are not provided here because the excessive flocculation of the hair bundles caused by too poor cleaning ability affects the objectivity of the data). The commercial samples are the same as in Experimental Example 1.

[0059] Table 5 Glossiness Test Results

[0060] Sample Immediate Gloss Increase (%) 1h Gloss Increase (%) Example 1 37.8％ 46.8％ Example 2 34.6％ 45.1％ Example 3 35.6％ 45.8％ Example 4 37.5％ 46.4％ Example 5 37.1％ 46.6％ Example 6 36.5％ 43.3％ Example 7 37％ 45.5％ Comparative Example 3 33.1％ 40.3％ Comparative Example 4 34.5％ 44.2％ Comparative Example 5 34.2％ 42.8％ Comparative Example 6 33.8％ 40.2％ Comparative Example 7 25.3％ 28.1％ Comparative Example 8 34％ 43.7％ Commercially Available Sample 27.8％ 35.6％

[0061] As can be seen from the results in Table 5, the immediate gloss improvement and the gloss improvement after 1 h of the hair oils prepared in Examples 1-7 after washing and drying the hair bundles are both higher than those of the commercially available samples. From Examples 1-3, it can be seen that increasing the proportion of linear polysiloxane and decreasing the proportion of polyol contribute to improving the gloss of hair strands. From Examples 4-5, it can be seen that the type of nonionic surfactant has little effect on the gloss of hair bundles. Compared with Example 1, the gloss improvement of the hair bundles in Examples 6-7 decreases, indicating that increasing the proportion of Macadamia ternifolia seed oil is more beneficial to improving the gloss of hair bundles. From Comparative Examples 3-5, it can be seen that Macadamia ternifolia seed oil is more beneficial to improving the gloss of hair bundles. Compared with Example 1, adding a large amount of a single vegetable oil in Comparative Example 8 cannot improve the gloss of hair strands, indicating that the combination of coconut oil, Macadamia ternifolia seed oil and jojoba oil has a synergistic effect on improving the gloss of hair bundles. From Comparative Examples 6-7, it can be seen that polyol has little effect on the gloss of hair bundles, linear polysiloxane plays a dominant role in improving the gloss of hair bundles, and vegetable oil plays an auxiliary role.

[0062] Experimental Example 4 Consumer Trial Evaluation

[0063] 140 product trial volunteers were recruited, with healthy hair color, long hair, and an age range of 20-40 years old. They were randomly divided into 14 groups, with 10 volunteers in each group. The commercially available samples (the same as in Experimental Example 1) and the samples of Examples 1-7 of the present invention were tested, and scores were given from 4 dimensions: foam amount, wet hair smoothness, three-layer appearance preference, and dry hair smoothness. The scoring range was 0-5 points, and finally the average score of each dimension of each group was taken. Since the volunteers do not have a unified concept of the superiority or inferiority of a certain dimension of the sample, the scoring results are only relative scores generated from the comparison between the commercially available product and the samples of the present invention, rather than absolute superiority or inferiority. Grade scoring standard: 0 points: poor; 1 point: slightly poor; 2 points: ordinary; 3 points: slightly good; 4 points: good; 5 points: very good.

[0064] Evaluation method: The volunteers tested the distributed samples, paid attention to the foam amount, wet hair smoothness, three-layer appearance preference, and dry hair smoothness of the products, and scored each dimension of the products after using them 3 times a week. The results are shown in Table 6. (Comparative Examples 6-7 did not meet the requirements for the double-layer appearance and were no longer tested.)

[0065] Table 6 Average Score Results of Each Index

[0066]

[0067]

[0068] As can be seen from the results in Table 6, consumers have a rather high evaluation of the dry hair effect of the hair oil products. As mentioned above, the main problems lie in the foaming ability and the smoothness of wet hair. The smoothness of wet hair of the samples in the embodiments of the present invention is higher than that of the commercially available samples. Among them, Example 1 has greater advantages in each dimension and is generally liked by the testers. By comparing the evaluation results of Examples 1-7 and Comparative Examples 1-2, it can be seen that Comparative Examples 1-2 lack the main surfactant MIPA lauryl ether sulfate, resulting in poor performance in terms of foam volume, smoothness of wet hair and three-layer appearance, leading to a low overall score. By comparing the evaluation results of Example 1, Examples 6-7 and Comparative Examples 3-5, it can be seen that in Comparative Examples 3-5, due to the decrease in the content of the main surfactant MIPA lauryl ether sulfate and the addition of a single vegetable oil, the scores of the products in terms of foam volume and smoothness of wet and dry hair are low. Comparative Example 8 has a similar formulation to Example 1, and a large amount of single oil is added in Comparative Example 8, resulting in a lower score of the product in terms of wet and dry hair than that of Example 1, which is in line with the foregoing conclusion.

[0069] In summary, the hair oil with a three-layer appearance provided by the present invention has the effects of rich foam, good detergency, smoothness of wet and dry hair, and nourishing hair strands, effectively solving the problems of single-phase hair oils currently on the market.

[0070] The preferred embodiments of the present invention have been specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art can also make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
