Description

Technical Field

[0001] The invention belongs to the technical field of ointment preparation, and in particular relates to a shower ointment with sustained and lasting fragrance, and a preparation method and application thereof. Background Art

[0002] Traditional perfume is liquid, so in many cases, it is inconvenient to carry, and its dosage is not easy to control. It is easy to spray too much at one time, resulting in a heavy fragrance on the body and waste. Balm is a paste, which is light in size and easy to control in dosage. Compared with perfume, it is more convenient to carry and will not leak. However, with the faster and faster pace of life and the improvement of quality of life, time-saving and convenient lifestyles have become more popular. For this reason, people's requirements for bathing are no longer limited to cleaning and cleansing the skin, but also require certain effects while bathing, such as aromatherapy. Most of the shower heads on the market currently only provide people with a simple shower function. In today's rapidly developing world, a simple shower function can no longer meet people's needs. Bath balm is a product used with a shower head when bathing. It is dissolved in water in the shower head and sprayed on the user through the shower head to achieve effects such as aromatherapy.

[0003] For example, Chinese patent CN210614058U discloses a slow-release perfume stick for perfume atomizing nozzle, which can realize that the water spray head sprays out bath liquid with perfume, and the bath liquid sprayed by the water spray head has perfume, which makes people feel refreshed and comfortable, and bathing is cleaner.

[0004] Another example is Chinese patent CN106311512A, which discloses an aromatherapy shower head, including a shower head and a bracket, on which a detachable aromatherapy bottle is arranged, the aromatherapy bottle is fixed to the middle and lower tube body of the bracket, and the shower head is detachably fixed to a fixing seat at the top of the bracket. This product is a good combination of aromatherapy and shower head, which allows people to get dual sensory relief and relaxation while bathing, showering, and soaking, greatly improving people's quality of life.

[0005] However, there are relatively few studies on shower ointment products. Chinese patent CN116531273A discloses a vitamin C gel for shower filter with multiple functions and its preparation method. It includes the following raw materials calculated by weight percentage: 30-60% vitamin C component, 5-20% gelling agent, 10-35% polyol, 10-25% functional component, 0.5-5% rheology regulator, 2-10% aromatherapy essential oil, 0.1-3% additive, and 1-5% pure water. The vitamin C gel for shower filter has the functions of dechlorination, anti-oxidation and whitening, improving hair loss, mild exfoliation and high moisturizing, and has stable performance and long service life. The fragrance produced by the aromatherapy essential oil during bathing makes people feel happy.

[0006] However, the sustained-release effect and fragrance persistence of the existing shower filter perfume are not good, so it is necessary to develop a shower perfume with continuous sustained-release fragrance and a preparation method and application thereof. Summary of the invention

[0007] In view of the deficiencies in the prior art, the present invention aims to provide a showerhead perfume with sustained and long-lasting fragrance, and a preparation method and application thereof.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions: On the one hand, the present invention provides a showerhead balm with sustained and long-lasting fragrance, which comprises the following components by weight percentage: 1.5-3% thickener, 10-20% solubilizer, 15-30% fragrance, 0.3-0.8% emulsifier, 0.1-0.3% chelating agent, 0.1-0.5% antioxidant, 0.2-0.5% preservative, 2-5% emollient, 0.3-0.8% sustained-release agent and the remainder water.

[0009] Preferably, the shower ointment comprises the following components by weight percentage: 2-2.5% thickener, 12-18% solubilizer, 20-25% fragrance, 0.5-0.7% emulsifier, 0.2-0.3% chelating agent, 0.2-0.4% antioxidant, 0.3-0.4% preservative, 3-4% emollient, 0.4-0.6% sustained-release agent and the remainder water.

[0010] in, The thickener is a mixture of a cross-linked polymer of polyvinyl methyl ether / methyl acrylate and decadiene and coconut aminohydroxysulfobetaine; The mass ratio of the cross-linked polymer of polyvinyl methyl ether / methyl acrylate and decadiene to coconut aminohydroxysulfobetaine is 3-8:1; Preferably, the mass ratio of the cross-linked polymer of polyvinyl methyl ether / methyl acrylate and decadiene to coconut aminohydroxysulfobetaine is 5:1.

[0011] The solubilizing agent is glycerol; The fragrance is a conventional bathing fragrance, that is, a daily fragrance.

[0012] The emulsifier is a mixture of dodecyl polyglucoside and cetearyl alcohol polyether-20; the mass ratio of the two is 1:1.

[0013] The emollient is cetearyl alcohol.

[0014] During the implementation of the present invention, it was found that the mass ratio of thickener, emulsifier and emollient was controlled to be 2-8:1:5-15; Preferably, the mass ratio of the thickener, emulsifier and emollient is 4:1:6.

[0015] During the implementation process, by controlling the mass ratio of the thickener, emulsifier and moisturizer, the fragrance can be better dispersed in the matrix, and the obtained balm has better stability. It is unexpectedly found that the selection and ratio of the thickener, emulsifier and moisturizer will affect the adhesion effect of the fragrance on the skin, which can make the fragrance last longer.

[0016] As some preferred embodiments, the chelating agent is disodium EDTA.

[0017] As some preferred embodiments, the antioxidant is a mixture of tocopherol and ascorbic acid; The mass ratio of tocopherol to ascorbic acid is 1:1; As some preferred embodiments, the tocopherol has a weight percentage of 0.05-0.25%, preferably 0.08-0.2%, more preferably 0.1-0.15%, and further preferably 0.1%.

[0018] As some preferred embodiments, the ascorbic acid has a weight percentage of 0.05-0.25%, preferably 0.08-0.2%, more preferably 0.1-0.15%, and further preferably 0.1%.

[0019] As a preferred embodiment, the antioxidant consists of 0.1% tocopherol and 0.1% ascorbic acid by weight.

[0020] As some preferred implementation schemes, the preservative is a mixture of phenoxyethanol and sodium benzoate, and the mass ratio of the two is 1:1.

[0021] As some preferred embodiments, the sustained-release agent is silica.

[0022] As a preferred embodiment, the essential oil shower gel comprises the following components by weight percentage: 2.0% cross-linked polymer of polyvinyl methyl ether / methyl acrylate and decadiene, 0.4% cocoamidohydroxysulfobetaine, 15% glycerin, 20% fragrance, 0.3% dodecyl polyglucoside, 0.3% ceteareth-20, 0.2% disodium EDTA, 0.1% tocopherol, 3.6% cetearyl alcohol, 0.1% ascorbic acid, 0.2% phenoxyethanol, 0.2% sodium benzoate, 0.5% silica and the balance water.

[0023] On the other hand, the present invention also provides a method for preparing a showerhead perfume with sustained and long-lasting fragrance, comprising the following steps: (1) Mix and disperse the flavor and the sustained-release agent for 3-5 minutes to obtain solution 1; (2) mixing part of the thickener, solubilizer and part of the preservative and dispersing them for 3-5 minutes to obtain solution 2; (3) Add the remaining thickener and the remaining preservative into water, stir evenly and heat to 80-90°C. After the mixture is completely dissolved, keep the temperature constant for 10-20 minutes to obtain a mixed solution. (4) Add the chelating agent, emulsifier and moisturizer to the mixed solution and continue to stir at a constant temperature for 3-5 minutes, then cool it to 60-70°C, add solution 1 and solution 2, stir at a constant temperature for 3-5 minutes, then cool it to 40-50°C, add the antioxidant, continue to stir for 10-15 minutes, pour it into a mold, cool it down, and then obtain the shower ointment.

[0024] In another aspect, the present invention further provides the use of the above-mentioned showerhead perfume in preparing a showerhead filter element, which is applied in the field of bathing.

[0025] The beneficial effects compared with the prior art are: The invention uses a mixture of a cross-linked polymer of polyvinyl methyl ether / methyl acrylate and decadiene and coconut aminohydroxysulfobetaine as a thickener, uses a mixture of dodecyl polyglucoside and cetearyl alcohol polyether-20 as an emulsifier, uses cetearyl alcohol as an emollient, and controls the mass ratio of the thickener, the emulsifier and the emollient to be 2-8:1:5-15, so that the fragrance can be better dispersed in the matrix, and the obtained balm has good stability. It is unexpectedly found that the selection and ratio of the thickener, the emulsifier and the emollient will affect the adhesion effect of the fragrance on the skin, so that the fragrance can be kept for a long time.

[0036] Comparative Example 1 The difference from Example 3 is that no emollient is added, the content of the solubilizer is 18.6%, and the rest is the same as Example 3.

[0037] Comparative Example 2 The difference from Example 3 is that the thickener is only a cross-linked polymer of polyvinyl methyl ether / methyl acrylate and decadiene, the emulsifier is only dodecyl polyglucoside, and the rest is the same as Example 3.

[0038] Comparative Example 3 The difference from Example 3 is that the mass ratio of thickener, emulsifier and emollient is 10:1:1, that is,

[0039] The rest is the same as Example 3.

[0040] Comparative Example 4 The difference from Example 3 is that the mass ratio of thickener, emulsifier and emollient is 1:1:3, that is,

[0041] The rest is the same as Example 3.

[0042] Effect experiment: 1. Stability test 1.1 Heat resistance: Keep at (45±1)℃ for 24 hours, and then return to room temperature to see if the oil penetration rate of the paste is less than 3%. Is there any obvious difference in properties compared with before the test?

[0043] 1.2 Cold resistance: Keep at (-10±2)℃ for 24 hours, then return to room temperature to check whether cracks appear in the paste and whether there are any obvious differences in properties compared with before the test.

[0044] The test results are shown in Table 1 below.

[0045] Table 1

[0046] According to the test results in Table 1 above, it can be seen that the shower ointment prepared by the present invention has high stability. After being placed under high and low temperature conditions, the ointment has no obvious difference in properties compared with before the test. In the comparative example, changing the types of thickeners and emulsifiers, or changing the mass ratio of thickeners, emulsifiers and emollients, will affect the physical and chemical properties of the ointment. After hot and cold treatment, the oil permeation rate will increase or cracks will appear in the ointment.

[0047] 2. Sustained release effect detection Test method: Take 3 pieces of showerhead perfume prepared in Examples 1-3 and Comparative Examples 1-4 respectively, weigh the initial weight and place them in water at a constant temperature of 35°C. The volume, material, water quality and water mass of the water solvent are the same. After soaking for 10 minutes and 20 minutes respectively, use a paper towel to absorb the moisture on the surface of the perfume and measure the weight, and calculate the perfume loss rate (%). Balm loss rate (%) = (initial weight - measured weight) / initial weight × 100%; the results are shown in Table 2 below.

[0048] Table 2

[0049] According to the test results in Table 2 above, the shower fragrance prepared by the present invention has a better sustained-release effect, especially in Example 3, a mixture of a cross-linked polymer of polyvinyl methyl ether / methyl acrylate and decadiene and coconut aminohydroxysulfobetaine is used as a thickener, a mixture of dodecyl polyglucoside and cetearyl alcohol polyether-20 is used as an emulsifier, and cetearyl alcohol is used as an emollient, and the mass ratio of the thickener, the emulsifier and the emollient is controlled to be 4:1:6. The obtained shower fragrance has the best sustained-release effect, while the addition of an emollient in Comparative Example 1 has little effect on the sustained-release effect of the balm, and changing the types of thickeners and emulsifiers, or changing the mass ratio of thickeners, emulsifiers and emollients in Comparative Examples 2-4 will significantly affect the sustained-release effect of the balm.

[0050] 3. Long-lasting fragrance effect detection Smell identification method: 15 smellers were selected. This group of smellers had been screened in advance through smell experiments. They could easily distinguish deionized water, acetic acid with a mass concentration of 1%, and β-phenylethanol with a mass concentration of 1%. A 250g per square meter scent paper was used as a carrier and cut into 15.0×1.0cm paper strips. 3g of the shower paste prepared in Examples 1-3 and Comparative Examples 1-4 was dissolved in 50mL of 40℃ water to obtain the liquid to be tested. After cooling, the front 2.0cm of the paper strip was moistened with the liquid to be tested. They were asked to smell the solution to be tested on the scent paper at regular intervals in a room with the same temperature and humidity conditions until the fragrance disappeared, which was the retention time of the fragrance of the shower paste. The results were averaged and one decimal place was retained after the decimal point. The experimental results are shown in Table 3 below.

[0051] Table 3

[0052] According to the test results in Table 3 above, the showerhead perfume prepared in Examples 1-3 of the present invention has a more lasting fragrance effect, especially in Example 3, a mixture of a cross-linked polymer of polyvinyl methyl ether / methyl acrylate and decadiene and coconut aminohydroxysulfobetaine is used as a thickener, a mixture of dodecyl polyglucoside and cetearyl alcohol polyether-20 is used as an emulsifier, and cetearyl alcohol is used as an emollient, and the mass ratio of the thickener, the emulsifier and the emollient is controlled to be 4:1:6. The obtained showerhead perfume has the longest fragrance retention time, while the absence of an emollient in Comparative Example 1 has the greatest effect on the fragrance retention effect of the perfume, and changing the types of thickeners and emulsifiers, or changing the mass ratio of thickeners, emulsifiers and emollients in Comparative Examples 2-4 will significantly affect the fragrance persistence of the perfume.

[0053] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
