Description

Technical Field

[0001] This application relates to the field of fragrance technology, and more specifically, to a fragrance composition for oral care and cleaning and a method for preparing the same. Background Technology

[0002] In today's society, people's pursuit of quality of life has made oral care a key part of daily health management. Oral health is directly related to all aspects of life, from enjoying food and expressing oneself verbally to projecting confidence in social situations. Currently, the oral care and cleaning product market is booming, with a wide variety of products available, including toothpaste, mouthwash, dental floss, and oral sprays.

[0003] In oral care products, fragrances can give the product a fresh and pleasant taste, masking any bitterness or powdery taste that may be produced by abrasives, detergents, or other ingredients, thus enhancing the enjoyment of brushing or rinsing. At the same time, fragrances help to keep breath fresh for longer by neutralizing odor molecules in the mouth (such as food residue and bacterial metabolites). Therefore, the use of fragrances greatly enhances the user experience.

[0004] Regarding the aforementioned technologies, the inventors believe that although the fragrances in oral care cleaning products can bring about the above-mentioned effects, due to the special nature of the oral environment, the fragrances are accelerated to decompose and volatilize due to saliva washing, chewing activities and pH changes, resulting in a short-lasting fragrance after cleaning and difficulty in maintaining a fresh state of the mouth for a long time, which cannot meet people's needs in long-term social and work scenarios.

[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 fragrance retention time of fragrances after application in oral care cleaning products, so that the fragrance can remain in the mouth for a long time and keep the mouth fresh, this application provides a fragrance composition for oral care cleaning and a method for preparing the same.

[0007] In a first aspect, this application provides a fragrance composition for oral care and cleaning, employing the following technical solution: A fragrance composition for oral care and cleaning, made from raw materials comprising the following parts by weight: 5-10 parts of linalool; 5-10 parts Asian peppermint oil; 10-50 parts of synthetic menthol; 10-50 parts of fragrance solvent; 1-5 parts of methyl dihydrojasmonic acid; 1-5 parts of benzyl acetate; 1-5 parts of phenylethanol; 1-5 parts of linalyl acetate; 1-5 parts of cis-jasmone.

[0008] By employing the above-mentioned technical solutions, the combination of Asian peppermint oil and synthetic menthol provides an instant cooling sensation through high volatility, while simultaneously suppressing bad breath, functioning as a top note freshening layer. Linalool provides a lily-of-the-valley-like fresh floral base, synergizing with the rose sweetness of phenethyl alcohol to mimic the sweet main aroma of camellia; benzyl acetate enhances the three-dimensionality of the floral fragrance, synergizing with cis-jasmone to elevate the natural layers of the aroma and maintain the main camellia aroma; it functions as a core body fragrance layer. The cyclopentenone skeleton of dihydrojasmonate and the monoterpene ester structure of linaloacetate form a gradient volatility system, enabling long-lasting fragrance release. Furthermore, in the oral environment, the two associate through hydrogen bonds, reducing overall volatility, and bind to salivary mucins to form a sustained-release film layer. This allows the fragrance to maintain stability under the influence of saliva rinsing, chewing activities, and pH changes, thus significantly improving the retention time of the fragrance after application to oral care products, allowing the aroma to linger in the mouth for a long time and continuously maintain fresh breath.

[0009] Preferably, the raw materials also contain 5-10 parts by weight of functional additive A, wherein the functional additive A is composed of benzyl salicylate and bicarbonate particles, and the weight ratio of benzyl salicylate to bicarbonate particles is 1:(1.8-2.6).

[0010] By employing the above technical solution, bicarbonate particles can neutralize the acidic environment of the oral cavity, inhibit odors produced by bacterial metabolism, and protect fragrance components from acidic degradation. Furthermore, the bicarbonate ions generated by ionization bind to oral glycoproteins, forming an alkaline sustained-release layer and prolonging the residence time of aroma molecules. Benzyl salicylate, with a boiling point of 300℃, can significantly reduce the overall volatility of the fragrance, extending the release time of the main camellia fragrance components (such as linalool and phenylethyl alcohol). Moreover, the benzyl ring and ester group of benzyl salicylate give it both lipophilic and weakly hydrophilic properties, allowing it to simultaneously bind to… Oral mucosal proteins and sebum secretions form a sustained-release film, thus achieving long-lasting fragrance. When benzyl salicylate and bicarbonate particles are used as functional additive A, they can exert excellent synergistic effects. The ionic bonding structure formed by the bicarbonate particles and benzyl salicylate, and the micron-level rough surface of the combination promote the adhesion of fragrance molecules to the oral mucosa, can significantly improve the fragrance retention time after the application of oral care products, and finally obtain a fragrance composition with excellent application quality for oral care.

[0011] Preferably, the weight ratio of benzyl salicylate to bicarbonate particles is 1:2.2.

[0012] By adopting the above technical solution, when benzyl salicylate and bicarbonate particles are used in combination at the above weight ratio, the synergistic effect is excellent. Not only can they fully cooperate with other raw materials, but they can also be uniformly dispersed in the fragrance mixture system, thereby ensuring that a fragrance composition with better quality for oral care is obtained.

[0013] Preferably, the bicarbonate particles have a porous spherical structure with a particle size of 10-50 μm, an average pore diameter of 0.1-1 μm, and a porosity of 60-80%.

[0014] By adopting the above technical solution, the bicarbonate particles are selected with a porous spherical structure, which can improve the loading of fragrance molecules. The average pore diameter is 0.1-1μm and the porosity is 60-80%. In addition to further optimizing and improving the loading of fragrance molecules, it can also form a pH buffer reservoir, continuously release bicarbonate ions, and exert a stable and continuous corresponding effect. At the same time, if the particle size of the bicarbonate particles is too small, they will be easily dissolved by saliva, and if they are too large, they will reduce the adhesion to the mucous membrane. The size of 10-50μm can ensure that it plays an excellent stabilizing role in the application process.

[0015] Preferably, the raw materials also contain 2-5 parts by weight of functional additive B, which is composed of propolis and betaine, and the weight ratio of propolis to betaine is 1:(0.1-0.3).

[0016] By adopting the above technical solutions, the ester components of propolis can form a 0.5-2μm breathable protective film in the oral cavity, encapsulating and slowly releasing the aroma components, thus prolonging the aroma residue time. Furthermore, its film-forming properties reduce the aroma loss rate caused by saliva rinsing. Betaine carries water molecules to the oral mucosa surface, improving the solubility of the fragrance components and maintaining oral pH stability, preventing the hydrolysis of aroma components caused by an acidic environment. When propolis and betaine are used as functional adjuvant B, the zwitterionic structure of betaine electrostatically adsorbs with propolis, enhancing the dispersion stability of the aroma components in saliva. This significantly reduces the impact of saliva rinsing, chewing activities, and pH changes on the fragrance composition, thereby significantly extending the fragrance retention time after applying oral care products and maintaining a fresh breath.

[0017] Preferably, the weight ratio of propolis to betaine is 1:0.2.

[0018] By adopting the above technical solution, when propolis and betaine are used in combination at the above weight ratio, the synergistic effect is excellent. Not only can they fully cooperate with other raw materials, but they can also be evenly dispersed in the fragrance mixture system, thereby ensuring that a fragrance composition with better quality for oral care and cleaning is obtained.

[0019] Preferably, the fragrance solvent is dipropylene glycol.

[0020] By adopting the above technical solution, dipropylene glycol has good co-solubility with water, oil and hydrocarbons. It can not only dissolve and carry fragrance components, so that they are evenly distributed in the product, but also prolong the fragrance retention time. At the same time, due to its low volatility and good stability, it can ensure that the fragrance is continuously released during the use of the product.

[0021] Secondly, this application provides a method for preparing a fragrance composition for oral care and cleaning, using the following technical solution: A method for preparing a fragrance composition for oral care and cleaning includes the following steps: (1) Prepare raw materials containing linalool, Asian peppermint oil, synthetic menthol, fragrance solvent, methyl dihydrojasmonate, benzyl acetate, phenylethanol, linalool acetate and cis-jasmone according to the weight ratio; (2) Place each raw material in step (1) into a mixing container and mix them. After mixing evenly, homogenize the resulting liquid under high pressure to obtain a fragrance composition for oral care.

[0022] By adopting the above technical solution and preparation method, the operation process is simple, the production is stable, the product quality is excellent, the overall applicability is good, and it is suitable for large-scale industrial production.

[0023] In summary, this application has the following beneficial effects: 1. This application forms a gradient volatile system by using the cyclopentenone skeleton of dihydrojasmonate methyl ester and the monoterpene ester structure of linalyl acetate to form a sustained-release film layer through hydrogen bonding in the oral environment and binding with salivary mucin. This can significantly improve the fragrance retention time after the application of oral care and cleaning products, allowing the fragrance to remain in the oral cavity for a long time and continuously maintain oral freshness. 2. By using functional additive A, which consists of benzyl salicylate and bicarbonate particles, and functional additive B, which consists of propolis and betaine, this application can significantly reduce the influence of saliva rinsing, chewing activities and pH changes on the fragrance composition, thereby significantly improving the fragrance retention time after the application of oral care cleaning products and maintaining a fresh mouth.

[0049] Performance testing test samples: The fragrance compositions for oral care and cleaning obtained in Examples 1-20 were selected as test samples 1-20, and the fragrance compositions for oral care and cleaning obtained in Comparative Examples 1-3 were selected as control samples 1-3.

[0050] Test methods: Commercially available Xinmeike antibacterial mouthwash, which contains no added alcohol or fragrance, was used as the base for the mouthwash. 0.2% by weight of a fragrance composition for oral care was added, and the mixture was then used to obtain the mouthwash sample. Commercially available Anatomicals toothpaste, which is free of pigments, preservatives, and fragrance, was also used as the toothpaste base. 0.2% by weight of a fragrance composition for oral care was added, and the mixture was then used to obtain the toothpaste sample. Forty-six volunteers were selected and randomly divided into 23 groups of two, with half males and half females. The mouthwash and toothpaste samples prepared from test samples 1-20 and control samples 1-3 were used. The mouthwash sample was used 12 mL each time and brushed in the mouth for 45 seconds. The toothpaste sample was used 0.5 g each time and brushed for 2 minutes. The mouthwash and toothpaste samples were tested 1 day apart. According to the national standard GB / T 14454.2-2008 "Fragrance Evaluation Method", five sensory evaluators were selected and tested using the triangulation method to ensure that they could quickly and accurately distinguish different aroma concentrations. The sensory evaluators measured the lasting fragrance time of volunteers after using mouthwash and toothpaste samples. The average value for each group of volunteers was recorded as the final lasting fragrance time, and the results are recorded in Table 2.

[0051] Table 2 Test results of test samples 1-20 and control samples 1-3 As can be seen from Examples 1-3 and Comparative Examples 1-3, and Table 2, the combination of methyl dihydrojasmonate and linalyl acetate in the fragrance composition for oral care can prolong the fragrance's retention in the mouth. The lasting fragrance time of the mouthwash sample and the toothpaste sample obtained in the above application tests were significantly improved. If either methyl dihydrojasmonate or linalyl acetate is added alone, although it can bring about a corresponding improvement, the improvement is limited, and the sum of the improvement brought by the individual use of the two is far less than the improvement brought by the combination of the two. It can be seen that the combination of methyl dihydrojasmonate and linalyl acetate can bring about a synergistic effect in the fragrance composition for oral care, thereby significantly improving the fragrance's retention time after application of oral care products.

[0052] As can be seen from Examples 1 and 4-8 and Table 2, the use of functional additive A, composed of benzyl salicylate and bicarbonate particles, can further improve the fragrance retention time of the fragrance composition after application in oral care cleaning products. Furthermore, as can be seen from Examples 9-10 and Table 2, the bicarbonate particles have a porous spherical structure with a particle size of 10-50 μm, an average pore diameter of 0.1-1 μm, and a porosity of 60-80%, ensuring that the bicarbonate particles and benzyl salicylate exert excellent effects when combined. Finally, as can be seen from Examples 11-12 and Table 2, the bicarbonate particles and benzyl salicylate have a synergistic effect, significantly improving the lasting fragrance time of the mouthwash sample and the toothpaste sample obtained in the above tests.

[0053] As can be seen from Examples 1 and 13-17, and Table 2, the use of functional additive B, composed of propolis and betaine, significantly reduces the impact of saliva rinsing, chewing activity, and pH changes on the fragrance composition, thereby further improving the lasting fragrance time. Furthermore, as can be seen from Examples 18-19 and Table 2, propolis and betaine have a synergistic effect, significantly improving the lasting fragrance time of the mouthwash and toothpaste samples tested above. Finally, as can be seen from Example 20 and Table 2, the combined use of functional additives A and B results in a significant synergistic effect (1+1>2), leading to a higher quality fragrance composition for oral care.

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.
