Description

Technical Field

[0001] This application relates to the field of fragrance and flavor technology, and more specifically, to a marine mint toothpaste flavoring and its preparation method. Background Technology

[0002] The fragrance used in toothpaste is made by blending natural and synthetic flavorings, referencing the aroma of natural plants. It has natural flavors and various fragrance types of raw materials. It not only gives toothpaste a certain type of aroma, but also a certain type of taste, so that consumers feel a cool and refreshing sensation in their mouths when using it, making consumers accept and use it happily.

[0003] Toothpaste flavoring consists of a peppermint base and a prominent flavor component that gives the product its characteristic aroma. Children's toothpaste flavoring has more prominent flavor component and less peppermint base; household and adult toothpaste flavoring has more peppermint base and less prominent flavor component. The main difference between different types of toothpaste flavoring lies in the different proportions of peppermint base and prominent flavor component. The composition of prominent flavor component is diverse, which brings a rich variety to toothpaste flavoring.

[0004] In related technologies, in order to continuously optimize the flavor and taste of toothpaste, toothpaste fragrances often use a variety of complex fragrance base ingredients mixed together. Although this can achieve the purpose of new product development, for people with sensitive mouths, such fragrances often easily cause certain oral irritation, which greatly affects the consumer's user experience.

[0005] Therefore, there is an urgent need to propose a solution to address the aforementioned technical problems. Summary of the Invention

[0006] In order to improve the richness of toothpaste flavor while minimizing oral irritation for people with sensitive mouths, this application provides a marine mint toothpaste flavor and its preparation method.

[0007] In a first aspect, this application provides a marine mint toothpaste flavoring, which adopts the following technical solution:

[0008] A marine mint toothpaste flavoring, comprising the following components in parts by weight:

[0009] Watermelon aldehyde 0.25-0.35 parts;

[0010] Phenylacetyl alcohol 0.8-1.2 parts;

[0011] Peppermint oil 9.5-10.5 parts;

[0012] Spearmint oil 4.5-5.5 parts;

[0013] 42-48 servings of menthol;

[0014] Citral 0.35-0.45 parts;

[0015] Eucalyptus oil 4.5-5.5 parts;

[0016] 4.5-5.5 parts anise oil;

[0017] Clove oil 0.45-0.55 parts;

[0018] Propylene glycol 15.2-16.4 parts;

[0019] WS-3 Menthamide 0.9-1.1 parts;

[0020] WS-23 Menthamide 0.9-1.1 parts;

[0021] 9-11 parts of peppermint essential oil.

[0022] By employing the above technical solution, the combination of peppermint oil, menthol, WS-3 mentholamide, WS-23 mentholamide, and peppermint essential oil can form an excellent and stable peppermint fragrance base. Watermelon aldehyde and citral provide a sweet aroma, serving as excellent highlighting fragrance components. Phenylethanol and anise oil enhance the fragrance and harmonize the aroma release between the various components. Propylene glycol, as a good solvent, enables the raw materials to form a uniform and stable mixture. The blend of spearmint oil, eucalyptus oil, and clove oil not only ensures a stable combination of the highlighting fragrance components and the peppermint fragrance base, facilitating the excellent combination of marine and mint elements in the fragrance, but also soothes the release of odors for people with sensitive mouths, regulates the stability of the oral environment, and significantly reduces irritation. Thus, the resulting marine peppermint toothpaste fragrance has excellent application effects.

[0023] Preferably, the marine mint toothpaste flavoring also contains 2.8-3.6 parts of a soothing composition, which is composed of bamboo leaf extract and cedar bud extract, and the weight ratio of bamboo leaf extract to cedar bud extract is 1:(1.2-1.8).

[0024] By adopting the above technical solution, the main components of the Lophatherum gracile extract are flavonoids and bioactive polysaccharides, which can exhibit excellent antioxidant effects and play a role in protecting the stability of the oral environment; the Cryptomeria japonica bud extract can strengthen the skin barrier function, play a calming and soothing role, and improve the oral cavity's ability to resist external stimuli; when the Lophatherum gracile extract and Cryptomeria japonica bud extract are combined in a specific weight ratio to form a soothing combination, they can play an excellent synergistic effect, especially for people with sensitive mouths, which can greatly reduce the irritation caused by the flavor of marine mint toothpaste and provide consumers with a better user experience.

[0025] Preferably, the weight ratio of the bamboo leaf extract to the cedar bud extract is 1:1.5.

[0026] By adopting the above technical solution, the bamboo leaf extract and cedar bud extract in the above weight ratio can exert a better synergistic effect. The resulting marine mint toothpaste flavor is less likely to irritate people with sensitive mouths after application, and the overall quality is better.

[0027] Preferably, the marine mint toothpaste flavoring also contains 30-40 parts of a coating wall material, which is composed of maltodextrin, modified starch and gum arabic, and the weight ratio of maltodextrin, modified starch and gum arabic is (0.7-0.9):(1.4-1.8):1.

[0028] By adopting the above technical solution and using the aforementioned wall material to encapsulate other component raw materials, the Ocean Mint toothpaste flavoring slowly releases its fragrance as the wall material breaks after application. This avoids irritation caused by concentrated local contact between the fragrance base and the oral cavity, greatly improving the stability of the Ocean Mint toothpaste flavoring application. Simultaneously, the wall material, composed of maltodextrin, modified starch, and gum arabic in a specific ratio, exhibits excellent adhesion after breaking, forming a protective film structure in the oral cavity. This significantly reduces the impact of complex fragrance base components on the user's oral cavity, thus greatly reducing irritation for people with sensitive mouths and resulting in a better overall effect.

[0029] Preferably, the weight ratio of the maltodextrin, modified starch and gum arabic is 0.8:1.6:1.

[0030] By adopting the above technical solution, when the above proportions of maltodextrin, modified starch and gum arabic are used as coating wall materials, not only can the coated fragrance components be released stably, but they can also have excellent adhesion to the user's oral cavity, which is conducive to forming a more stable protective film structure. In this way, the marine mint toothpaste fragrance is less likely to cause oral irritation to people with sensitive mouths.

[0031] Preferably, the modified starch is prepared by the following steps:

[0032] Take starch raw material and add 1.5-2 times the amount of water, stir evenly to obtain starch slurry; then add cyclic adenosine monophosphate, acid anhydride modifier and sodium hydroxide solution to starch slurry, maintain pH at 8-8.5 and stir reaction for 30-40 minutes, add hydrochloric acid to adjust pH to 4-5; finally filter, wash and dry to obtain modified starch.

[0033] By adopting the above technical solution, the modified starch prepared by the above method has excellent processing performance. It can form a stable coating wall material with maltodextrin and maltodextrin inter-component. After rupture, the film protective structure formed is more uniform and has a better ability to resist fragrance irritation. At the same time, the introduction of cyclic adenosine monophosphate during the modification process can assist the user's oral cavity in physiological regulation, greatly reduce the irritation caused by complex mixed fragrances to the oral cavity, and improve the user experience for people with sensitive mouths.

[0034] Secondly, this application provides a method for preparing marine mint toothpaste flavoring, employing the following technical solution: A method for preparing marine mint toothpaste flavoring, comprising the following steps:

[0035] (1) Prepare the raw materials containing watermelon aldehyde, phenylethyl alcohol, peppermint oil, spearmint oil, menthol, citral, eucalyptus oil, anise oil, clove oil, propylene glycol, WS-3 menthol, WS-23 menthol and peppermint essential oil according to the formula;

[0036] (2) Mix the raw materials in step (1) evenly and homogenize them under high pressure to obtain marine mint toothpaste flavoring.

[0037] By adopting the above technical solution, the above preparation method is simple to operate. It only requires mixing all the raw materials together evenly to obtain high-quality and stable marine mint toothpaste flavor. It has excellent production applicability and is easy to carry out large-scale industrial production.

[0038] Preferably, the marine mint toothpaste flavoring includes the following steps:

[0039] (1) Prepare raw materials containing watermelon aldehyde, phenylethyl alcohol, peppermint oil, spearmint oil, menthol, citral, eucalyptus oil, anise oil, clove oil, propylene glycol, WS-3 menthol, WS-23 menthol, peppermint essential oil and coating material according to the formula;

[0040] (2) Stir and mix the raw materials except the wall coating material in step (1) evenly, perform high pressure homogenization, and then disperse them in anhydrous ethanol to prepare a 4-5 mg / ml fragrance ethanol solution.

[0041] (3) Mix the coating material with water to prepare a wall material solution of 8-12 mg / ml; then add the fragrance ethanol solution from step (2) to the wall material solution, stir at a constant temperature of 25-35℃ for 5-7 hours, and freeze dry to obtain marine mint toothpaste fragrance.

[0042] By adopting the above technical solution and method, the coating wall material can stably encapsulate other component raw materials, achieving a high encapsulation rate and a high effective utilization rate of each raw material, thereby obtaining a high-quality marine mint toothpaste flavor.

[0043] In summary, this application has the following beneficial effects:

[0044] 1. This application uses peppermint oil, menthol, WS-3 mentholamide, WS-23 mentholamide and peppermint essential oil as peppermint base, watermelon aldehyde and citral as prominent fragrance components, and with the combined effect of spearmint oil, eucalyptus oil and clove oil, not only does the fragrance exhibit an excellent combination of marine and peppermint elements, but it also reduces the irritation of the fragrance to people with sensitive mouths, thus making the obtained marine peppermint toothpaste fragrance have excellent application effects;

[0045] 2. This application incorporates a soothing composition consisting of bamboo leaf extract and Japanese cedar bud extract in a specific weight ratio, which can enhance the oral barrier and protect the stability of the oral environment for people with sensitive mouths. This can greatly reduce the irritation caused by the flavor of marine mint toothpaste and provide consumers with a better user experience.

[0046] 3. This application uses a coating wall material composed of maltodextrin, modified starch and gum arabic in a specific weight ratio, which can slowly release the fragrance base component, making it less likely for the fragrance base component to concentrate locally and cause oral irritation. Moreover, when the coating wall material is broken, it can adhere to the oral cavity to form a protective film structure. In this way, the irritation caused by the marine mint toothpaste fragrance to people with sensitive mouths can be greatly reduced, and the overall effect is better. Detailed Implementation

[0154] Performance testing test samples: The marine mint toothpaste flavoring obtained in Examples 1-31 was used as test samples 1-31, and the marine mint toothpaste flavoring obtained in Comparative Examples 1-7 was used as control samples 1-7.

[0155] Test Methods: Test samples 1-31 and control samples 1-7 were tested according to the pharmaceutical industry standard 0279-1995, "Biological Testing Methods for Dental Materials - Oral Mucosal Irritation Test." This standard is applicable to evaluating the irritant effects of dental materials that are in temporary or long-term contact with oral mucosa tissue. After testing, scores were assigned based on the pathological reactions specified in the standard. The scoring criteria are as follows: none (0-5 points, inclusive), mild (5-9 points, inclusive), moderate (9-12 points, inclusive), and severe (12-16 points). The average score for each group was taken, and the corresponding test samples 1-31 and control samples 1-7 are recorded in Table 2 below.

[0156] Table 1 shows the test results of test samples 1-31 and control samples 1-7.

[0157]

[0158]

[0159] Based on Example 1 and Comparative Examples 1-7, and in conjunction with Table 2, it can be seen that the combination of spearmint oil, eucalyptus oil, and clove oil can significantly reduce the irritation of marine mint toothpaste flavoring to oral mucosa, making it more suitable for people with sensitive mouths. However, adding any one of spearmint oil, eucalyptus oil, or clove oil alone has a limited effect on reducing irritation, or using any two in combination only results in a simple additive effect. Only when all three ingredients are combined does the overall effect become more outstanding, achieving a synergistic effect greater than the sum of its parts.

[0160] Based on Examples 1 and 4-8 and Table 2, it can be seen that adding a soothing composition consisting of Lophatherum gracile extract and Cryptomeria japonica bud extract in a weight ratio of 1:(1.2-1.8) can further reduce the irritation of marine mint toothpaste fragrance on oral mucosa. The overall effect is particularly good when the weight ratio of Lophatherum gracile extract to Cryptomeria japonica bud extract is 1:1.5. Furthermore, based on Examples 9-10 and Table 2, it can be seen that when the ratio of Lophatherum gracile extract to Cryptomeria japonica bud extract exceeds the above-mentioned range, the corresponding improvement is somewhat reduced. Furthermore, based on Examples 11-12 and Table 2, it can be seen that adding Lophatherum gracile extract or Cryptomeria japonica bud extract alone does not produce a significantly better effect than the combination of the two. In conclusion, using a soothing composition consisting of Lophatherum gracile extract and Cryptomeria japonica bud extract in a specific weight ratio has a significant effect on reducing the irritation of fragrance to people with sensitive mouths.

[0161] Combining Examples 1 and 13-19 with Table 2, it can be seen that adding a coating material composed of maltodextrin, modified starch, and gum arabic in a weight ratio of (0.7-0.9):(1.4-1.8):1 can significantly reduce the irritation of complex flavor components on the user's oral cavity, thereby greatly reducing the irritation experienced by users with sensitive mouths. The overall effect is particularly excellent when the weight ratio of maltodextrin, modified starch, and gum arabic is 0.8:1.6:1. Combining Examples 20-21 with Table 2, it can be seen that when the ratio of the three components exceeds the above-mentioned dosage range, the effect of the coating material is somewhat diminished. Combining Examples 22-27 with Table 2, it can be seen that while using any one or two of maltodextrin, modified starch, and gum arabic can reduce the irritation of marine mint toothpaste flavor on the oral mucosa to some extent, the effect is far less superior than the combination of all three.

[0162] As can be seen from Examples 1, 28-29, and 31, and Table 2, the use of modified starch, compared with the same starch raw material, exhibits a more excellent stabilizing effect when combined with maltodextrin and gum arabic, greatly reducing the irritation of the marine mint toothpaste flavor to the oral mucosa. Furthermore, as can be seen from Example 30 and Table 2, the introduction of cyclic adenosine monophosphate during the modification process can assist in the physiological regulation of the user's oral cavity, greatly reducing the irritation caused by complex mixed flavor bases and improving the user experience for people with sensitive mouths.

[0163] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
