Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of daily chemical products, in particular to a transparent shampoo with fluffy and anti-dandruff effects and a preparation method thereof. BACKGROUND

[0002] In today's shampoo market, consumers' demand for shampoo is increasingly diversified, not only requiring good cleaning ability, but also expecting various care effects on hair and scalp. Transparent shampoo is popular in the market because of its clear and transparent appearance, giving consumers a more intuitive high-quality experience.

[0003] However, in the existing sulfate system transparent shampoo, the sulfate surfactant system has strong cleaning ability, which can easily irritate the scalp, cause dryness and tightness of the scalp, and cause discomfort, and also cause great damage to the hair quality after dyeing and perming, making the hair cuticle open and the hair dry and tangled.

[0004] To solve the above problems, emulsified silicone oil is commonly used as a conditioner in existing transparent shampoo, but it has a thick and sticky feeling, making the hair have poor support; or cationic guar gum is used, with a single or small amount of cationic high molecular weight conditioner (such as polyquaternium-7, polyquaternium-10, etc.), which can improve combing and fluffiness, but the effect is limited.

[0005] To pursue the anti-dandruff effect, piroctone olamine (OCT) is commonly used as an anti-dandruff agent in existing transparent shampoo. These ingredients have a clear anti-dandruff effect, but they can easily change color in the shampoo system and easily develop drug resistance. Therefore, a mild and effective anti-dandruff solution that is transparent and long-term stable is needed. SUMMARY

[0069] Figure 1 The figure shows the appearance schematic diagram of the transparent shampoo with the fluffy and dandruff-removing effect provided by the present application. DETAILED DESCRIPTION

[0070] The present application will be further described in detail below by specific preferred embodiments combined with effect test examples, but the present application is not limited to the following embodiments.

[0071] In order to solve the damage to the dyed and permed hair caused by the strong cleaning ability of the sulfate surfactant, the existing transparent shampoo adds traditional conditioning ingredients, but there are problems of single conditioning performance and sticky use feeling. In order to solve the problem, the present application proposes the combined use of polyquaternium-10 (PQ-10), polyquaternium-11 (PQ-11) and polyquaternium-51 (PQ-51), which can repair damaged hair and has a certain supporting, fluffy, moisturizing and hair care effect.

[0072] In order to solve the dandruff problem, the dandruff-removing ingredients added in the existing transparent shampoo have strong irritation. In order to solve the problem, the present application proposes the combined use of capryloyl glycine and magnolol, which has a good inhibitory effect on the key microorganism malassezia that causes dandruff, and also has oil control and is more mild compared with traditional dandruff-removing ingredients.

[0073] In addition, in order to solve the problem of precipitation of capryloyl glycine in the system, which affects the transparency, stability and effect, the present application proposes a process path for effectively dispersing and stabilizing the introduction of capryloyl glycine; in order to solve the solubility problem of magnolol, the present application also proposes an introduction process.

[0074] A shampoo with transparent appearance, the shampoo uses deionized water as the main solvent, and based on the total mass of the shampoo, the shampoo further comprises the following mass fractions of components:

[0075] 10wt%-20wt% of sodium laureth sulfate;

[0076] 0.5wt%-10wt% of ammonium laureth sulfate;

[0077] 0.5wt%-10wt% of cocamidopropyl betaine;

[0078] 0.5wt%-10wt% of cocoyl fatty acid monoethanolamide;

[0079] 0.5wt%-10wt% of decyl glucoside;

[0080] 0.6wt%-1.5wt% of capryloyl glycine;

[0081] 0.1wt%-1wt% of cationic guar gum;

[0082] 0.1wt%-1wt% of polyquatemium-10;

[0083] 0.1wt%-1wt% of polyquatemium-11;

[0084] 0.1wt%-1wt% of polyquatemium-51;

[0085] 0.01wt%-2wt% of magnolol;

[0086] 0.01wt%-2wt% of menthol;

[0087] 0wt%-1wt% of sodium chloride;

[0088] 0wt%-1wt% of citric acid.

[0089] In one or more embodiments, the preparation method of the shampoo comprises the following steps:

[0090] Step one, add part of deionized water into the reaction kettle;

[0091] Step two, pre-disperse the cationic guar gum with a small amount of deionized water, then add it into the reaction kettle and mix evenly, and then add polyquatemium-10 into the reaction kettle and mix evenly;

[0092] Step three, add cocamidopropyl betaine into the reaction kettle and mix evenly, and then heat to 70-95℃, and then add sodium laureth sulfate, ammonium laureth sulfate and cocofatty acid monoethanolamide into the reaction kettle respectively and mix evenly until the material body is transparent;

[0093] Step four, heat decyl glucoside to 70-95℃, add capryloyl glycine, and then add it into the reaction kettle and mix evenly after the capryloyl glycine is completely dissolved in the decyl glucoside.

[0094] Step five, dissolve magnolol with menthol, and then add it into the material body and mix evenly;

[0095] Step six, add polyquatemium-11 and polyquatemium-51 into the reaction kettle and mix evenly, and then adjust the pH with citric acid and adjust the viscosity with sodium chloride, and then discharge the material to obtain the shampoo.

[0096] The shampoo disclosed in the application adopts polyquaternium-10, polyquaternium-11 and polyquaternium-51 to construct a complex cationic conditioning system, which is different from the conventional use of a single conditioner or a low cationic density combination. It is unexpectedly found that the multi-component system has good combing performance, has film feeling and natural smooth conditioning, and can enhance the support of the hair and has good fluffiness.

[0097] In the shampoo disclosed in the application, capryloyl glycine is used as a conditioner, which is originally intended to regulate sebum secretion and improve the comfort after cleaning. It is unexpectedly found that the complex of capryloyl glycine and magnolol has an inhibitory effect on common microorganisms on the scalp, maintains the microecological balance of the scalp while conditioning mildly, and exhibits excellent antibacterial and anti-dandruff performance.

[0098] In one or more embodiments, the shampoo further comprises a preservative comprising one or more of benzyl alcohol, phenoxyethanol, hexylene glycol, potassium sorbate, sodium benzoate, and ethylhexylglycerin.

[0099] Key points:

[0100] Capryloyl glycine has poor solubility and weak complexing ability in an anionic surfactant system mainly composed of sulfates due to the hydrophobic aliphatic acyl chain and weakly acidic carboxyl group in its structure, which often leads to turbidity, precipitation or unstable efficacy in the formula, making it difficult to be applied to transparent shampoo products for a long time. The present application breaks through this technical bottleneck by innovatively designing the addition method of capryloyl glycine.

[0101] In the present application, capryloyl glycine is dissolved in decyl glucoside heated to 70-95°C and then introduced into the main system. The good interfacial activity and dispersion ability of decyl glucoside are used to build a stable micro-distribution environment, so that capryloyl glycine is uniformly dissolved, long-term clear and functional in transparent shampoo, as shown in Figure 1 .

[0102] In addition, the addition of magnolol and capryloyl glycine realizes the synergistic antibacterial and anti-dandruff effect. The method of dissolving magnolol and menthol together and then adding the material to the body is used to maintain the transparent appearance of the shampoo. At the same time, in order to increase the order of the shampoo, polyquaternium-10, polyquaternium-11 and polyquaternium-51 are introduced into the formula to realize the effect of hair smoothing and improving combing.

[0103] 1. Specific introduction method of capryloyl glycine:

[0104] a) a step of protecting capryloyl glycine from being dissolved in decyl glucoside under heating conditions (70-95°C, preferably 85°C) to form a uniform solution;

[0105] b) The time sequence of the introduction of octanoyl glycine, i.e. after the initial construction of the main system, the solution of decyl glucoside and octanoyl glycine is introduced to stabilize its distribution;

[0106] c) The sequence improves the appearance clarity and stability of the product compared with the traditional "direct feeding" or "cosolvent dispersion" method.

[0107] 2. The introduction method of Magnolol: added after being co-dissolved with menthol.

[0108] 3. The formula and transparent appearance of the shampoo based on the above process.

[0109] 4. The complex cationic conditioning system of Polyquatemium-10, Polyquatemium-11 and Polyquatemium-51.

[0110] 5. The antibacterial and anti-dandruff combination of Magnolol and octanoyl glycine.

[0116] The preparation method of the shampoo of Examples 1-3 above comprises the following steps:

[0117] Step one, add part of deionized water into the reaction kettle;

[0118] Step two, pre-disperse the cationic guar gum uniformly with a small amount of deionized water, then add it into the reaction kettle and mix uniformly, and then add Polyquatemium-10 into the reaction kettle and mix uniformly;

[0119] Step three, add cocamidopropyl betaine into the reaction kettle and mix uniformly, heat to 70-95°C, and then add sodium lauryl ether sulphate, ammonium lauryl ether sulphate and cocofatty acid monoethanolamide into the reaction kettle respectively, and mix uniformly until the material body is transparent;

[0120] Step four, take decyl glucoside and heat to 70-95°C, add octanoyl glycine, and after the octanoyl glycine is completely dissolved in the decyl glucoside, add it into the reaction kettle and mix uniformly.

[0121] Step five, dissolve Magnolol with menthol, and then add it into the material body and mix uniformly;

[0122] Step six, add polyquaternium-11, polyquaternium-51 into the reaction kettle, mix well, then adjust pH with citric acid, adjust viscosity with sodium chloride, and then discharge to obtain the shampoo.

[0123] Comparative Examples 1-12

[0124] In Comparative Examples 1-6, the components and addition process are the same as those in Example 1, except that decyl glucoside and octanoyl glycine are added in the following amounts and methods:

[0125] Comparative Example 1: No octanoyl glycine is added, and 4 wt% decyl glucoside is directly added into the reaction kettle and stirred evenly;

[0126] Comparative Example 2: No decyl glucoside is added, and 0.6 wt% octanoyl glycine is directly added into the reaction kettle and stirred evenly;

[0127] Comparative Example 3: 4 wt% decyl glucoside is first added, and then 0.6 wt% octanoyl glycine is directly added into the reaction kettle and stirred evenly;

[0128] Comparative Example 4: 0.6 wt% octanoyl glycine is first added, and then 4 wt% decyl glucoside is added into the reaction kettle and stirred evenly;

[0129] Comparative Example 5: Before adding the coconut fatty acid monoethanolamide, 0.6 wt% octanoyl glycine dissolved in 4 wt% decyl glucoside at 85°C is added;

[0130] Comparative Example 6: After cooling, 0.6 wt% octanoyl glycine dissolved in 4 wt% decyl glucoside at 85°C is added.

[0131] Comparative Example 7: 0.05 wt% magnolol and 0.05 wt% menthol are respectively added, and the remaining components and process are the same as those in Example 1.

[0132] Comparative Examples 8-12 have the following formulations shown in Table 2, and the process is the same as that in Example 1. Comparative Examples 8-9 are synergistic test examples of single use of octanoyl glycine or magnolol, and the test is Test 3; Comparative Examples 10-12 are synergistic test examples of binary complex of polyquaternium, and the test is Test 4-5.

[0134]

[0135]

[0136] The following are the contents of the efficacy test examples of the transparent shampoo of the present application.

[0137] Efficacy Test Example 1 Light Transmission Test

[0138] The shampoo samples of Examples 1-3 and Comparative Examples 1-7 were subjected to light transmittance tests, and the light transmittance of the samples at a visible light wavelength of 600 nm was tested using a spectrophotometer, with the light transmittance of a glass dish filled with 1 mL of deionized water being 100%, and the light transmittance of the same glass dish filled with the test sample being the transparency of the sample. The results are shown in Table 3.

[0139] Table 3: Light transmittance test results

[0140]

[0141] As can be seen from Table 3 above, the light transmittance of Examples 1-3 and Comparative Example 1 without the addition of octanoyl glycine is about 94%, and the material body is clear and transparent.

[0142] In Comparative Example 2, octanoyl glycine powder was directly added to the main system. Since the hydrophobic end of octanoyl glycine cannot fully interact with the water phase, micro-particles or liquid crystal aggregates are formed, which have a large particle size, resulting in increased light scattering and causing the system to be turbid.

[0143] In Comparative Examples 3 and 4, the decyl glucoside and octanoyl glycine were added simultaneously without pre-solubilization and stirring. The decyl glucoside cannot completely coat the octanoyl glycine, resulting in the free state of part of the octanoyl glycine and affecting the transparency of the material body.

[0144] In Comparative Examples 5 and 6, although the octanoyl glycine was pre-solubilized in the decyl glucoside, the micellar framework of the main system has not yet stabilized, and the octanoyl glycine cannot form a stable micro-dispersion state with the system, thereby showing a decrease in transparency.

[0145] In Comparative Example 7, magnolol was not pre-solubilized, resulting in the free state of part of the octanoyl glycine and affecting the transparency of the material body.

[0146] Efficacy Test Example 2 Stability Test

[0147] The shampoo samples of Examples 1-3 and Comparative Examples 1-7 were subjected to stability tests, and the specific contents are as follows:

[0148] Normal temperature test: The shampoo was placed in a constant temperature oven and left to stand at an ambient temperature of 25°C for one month;

[0149] High temperature test: The shampoo was placed in a constant temperature oven and left to stand at an ambient temperature of 48°C for one month;

[0150] Low temperature test: The shampoo was placed in a constant temperature oven and left to stand at an ambient temperature of -16°C for one month;

[0151] Cyclic temperature test: The shampoo was placed in a thermostat, and left to stand for 24 hours at an ambient temperature of 48°C, then for 24 hours at an ambient temperature of 25°C, then for 24 hours at an ambient temperature of -16°C, and finally for 24 hours at an ambient temperature of 25°C, to form one cycle, and the above cycle was repeated for 3 times.

[0152] After the test, the shampoo was taken out of the thermostat, and the appearance of the shampoo was observed visually. The test results are shown in Table 4, in which "OK" means that the appearance of the shampoo sample did not change, and "NG" means that the appearance of the shampoo sample became turbid.

[0153] Table 4: Stability test results

[0154]

[0155] According to the results in Table 4, the shampoo provided by the present application can maintain a stable transparent appearance for a long storage time and in a wide temperature range.

[0156] Efficacy Test Example 3 Dandruff Performance Test

[0157] It has been shown in previous studies that the production of dandruff is strongly correlated with the abnormal proliferation of Malassezia on the scalp. Therefore, the shampoo samples of Example 1 and Comparative Examples 8-9 were subjected to a Malassezia inhibition test, and the dandruff-removing performance of the samples was evaluated using the inhibition zone method.

[0158] For the liquid inhibition test sample, sterile and dry filter paper pieces were taken, 20 μL of the inhibition test sample solution at the actual use concentration was added to each piece, and then the filter paper pieces were placed flat in a clean sterile petri dish, and were dried in a thermostat (37°C) with the cover open. Sterile and dry filter paper pieces were taken, 20 μL of sterile distilled water was added to each piece as a blank control, and the pieces were dried for later use. A sterile cotton swab was dipped in the test bacterial suspension with a concentration of 5 x 10 5 cfu / mL-5 x 10 7 cfu / mL test bacterial suspension, and was spread evenly on the surface of the nutrient agar medium plate for 3 times. Each time, the plate was rotated by 60°, and finally a sterile cotton swab was used to spread around the edge of the plate. The plate was covered and dried at room temperature for 5 min.

[0159] For each test, 1 plate of the inoculated bacteria was placed, and 4 pieces of the test sample and 1 piece of the control sample were placed on each plate, for a total of 5 pieces. The sample pieces were placed on the plate surface using a sterile tweezers, and the centers of the pieces were separated by more than 25 mm, and the edge of the plate was separated by more than 15 mm. After the pieces were placed, a sterile tweezers was used to press the pieces tightly against the plate surface. The plate was covered and placed in a thermostat at 37°C, and the results were observed after 72 h of culture. The diameter of the inhibition zone was measured using a vernier caliper and recorded. The test was repeated for 3 times. The average diameter of the inhibition zone produced by each sample is shown in Table 5.

[0160] Table 5 results of antibacterial experiment

[0161]

[0162] According to the results in Table 5, the use of octanoyl glycine and magnolol in combination has a better inhibitory effect on malassezia than the use of octanoyl glycine or magnolol alone, and has a synergistic effect.

[0163] Efficacy Test Example 4 Combing Test

[0164] The combing performance of the shampoo samples of Example 1 and Comparative Examples 10-12 was tested.

[0165] The hair tresses with no difference in appearance were selected, soaked in a 5 g / L sodium dodecyl sulfate solution, rinsed with clean water after constant temperature water bath at 40°C for 30 min. Then the wet hair tresses were gently combed 10 times with a comb, and the combing work of the wet hair was measured with a texture analyzer to ensure 5 effective initial values. Then the tresses were hung in a constant temperature and humidity environment at a temperature of 25°C and a relative humidity of 55% for 24 h. When the weight difference of the tresses was less than 0.01 g in 5 min, the tresses were considered to reach the equilibrium state. The tresses were repeatedly combed 10 times with a comb to separate the hair roots and remove the tangles. The combing work of each tress was measured with a texture analyzer, and each tress was tested 3 times to take the average value as the initial value of the tress. The tresses with large deviation of the initial value were removed, and finally at least 5 effective initial values were ensured.

[0166] The tresses were wetted with 37.0°C tap water, 1 g of sample was applied on the tresses, and the tresses were kneaded and washed in the direction from the head to the end of the hair to ensure that the tresses were not disheveled and could be evenly sampled for 1 min. Then the tresses were rinsed with water at a flow rate of 4 L / min for 30 s, and the water on the tresses was squeezed from top to bottom every 5 s. The above process was repeated 3 times.

[0167] The wet tresses were gently combed with a comb, and the combing work of the wet hair was measured with a texture analyzer to ensure 5 effective initial values. The tresses were hung in a constant temperature and humidity chamber at a temperature of 25°C and a relative humidity of 55% for 24 h. When the weight difference of the tresses was less than 0.01 g in 2 consecutive measurements, the tresses were considered to reach the equilibrium state. The combing performance of the tresses after sampling was measured (after sampling), and the number of tests was consistent with the number of initial value tests before sampling. The average combing work before and after sampling was calculated to calculate the improvement rate of the sample on the combing of the tresses, and the results of each sample are shown in Table 6.

[0168]

[0169] Table 6 results of combing performance test

[0170]

[0171] According to the results in Table 6, the use of the three compounds PQ-10, PQ-11 and PQ-51 in combination shows a better dry and wet combing improvement effect than the conventional binary combination of polyquaternary ammonium salt.

[0172] Efficacy Test Example 5 Bulking Test

[0173] The shampoo samples of Example 1 and Comparative Examples 10-12 were subjected to the fluffiness performance test.

[0174] The hair strands with no difference in appearance were selected, soaked in a 5 g / L sodium dodecyl sulfate solution, and then rinsed with clean water after being kept in a constant temperature water bath at 40°C for 30 min. The hair strands were hung in a constant temperature and humidity chamber at a temperature of 25°C and a relative humidity of 55% for 24 h. When the difference in the gram weight of the hair strands between two consecutive measurements was less than 0.01 g, it was indicated that the hair strands reached the equilibrium state. The hair strands were not combed open, and the photos of the hair strands under the above condition were taken in a self-made shooting light box in the laboratory. The photos were imported into ImageJ image analysis software for pixel quantification, and the initial fluffiness value (Aera / Pixel) A0 of each hair strand was calculated.

[0175] A 1 g sample of the above hair strand was applied to the hair strand, and then kneaded and washed along the hair strand from the head to the end of the hair strand to ensure that the hair strand was not disheveled and could uniformly receive the sample for 1 min. Then the hair strand was rinsed with water at a flow rate of 4 L / min at 37.0°C for 30 s, and the water on the hair strand was clamped and pressed from top to bottom every 5 s. The above process was repeated for 3 times. The hair strand was hung in a constant temperature and humidity chamber at a temperature of 25°C and a relative humidity of 55% for 24 h. When the difference in the gram weight of the hair strands between two consecutive measurements was less than 0.01 g, it was indicated that the hair strands reached the equilibrium state. The hair strands were not combed open, and the photos of the hair strands under the above condition were taken in a self-made shooting light box in the laboratory. The photos were imported into ImageJ image analysis software for pixel quantification, and the fluffiness value (Aera / Pixel) A after use of each hair strand was calculated. x .

[0176] The improvement rate of the sample on the fluffiness of the hair strand was calculated according to the following formula, and the results of each sample are shown in Table 7.
