Description

Technical Field

[0001] The present application relates to the field of flavors, and more specifically, to a flavor composition with formaldehyde removal function and a preparation method thereof. Background Art

[0002] Formaldehyde, a colorless gas with a strong pungent odor that is widely present in our daily lives, has attracted considerable attention due to its significant harm to human health. It can originate not only from home improvement materials, new furniture, flooring, and various adhesives, but can also be found in certain everyday consumer products, such as cosmetics, detergents, and certain textiles. Long-term exposure to formaldehyde can cause irritation to the eyes, skin, and respiratory tract, leading to symptoms such as headaches, nausea, and coughing, and in severe cases, may even increase the risk of cancer. Therefore, developing effective formaldehyde removal technologies to reduce formaldehyde concentrations in living and working environments has become a critical issue in protecting public health.

[0003] Traditional space fragrance products, such as aromatherapy and air fresheners, are somewhat effective in removing foul odors, toxic chemicals, and gases from the air. However, their primary mechanism of action is to mask odors through the evaporation of fragrances, rather than fundamentally breaking down or removing harmful substances such as formaldehyde and bacteria. While these products can temporarily improve indoor air quality, they lack the ability to provide lasting, effective formaldehyde removal, nor do they meet consumers' growing demands for healthier and more environmentally friendly lifestyles.

[0004] Given the prevalence and potential hazards of formaldehyde, as well as the urgent market demand for efficient formaldehyde removal products, there is still room for improvement. Summary of the Invention

[0005] In order to improve the formaldehyde removal effect of a fragrance composition, the present application provides a fragrance composition with formaldehyde removal function and a preparation method thereof.

[0006] In the first aspect, the present application provides a fragrance composition with formaldehyde removal function, adopting the following technical solution: a fragrance composition with formaldehyde removal function, comprising the following components in percentage by mass: 0.1-1% vetiver oil, 0.05-0.5% elemi oil, 1-5% lemon oil, 3-8% pine needle oil, 1-5% eucalyptus oil, 3-8% rosemary oil, 28-32% ambergris, 0.05-0.2% thymol, 0.1-1% camphor, 3-8% modifier, 2-7% fixative and solvent.

[0007] By adopting this technical solution, the top note, combined with pine needle oil, eucalyptus oil, rosemary oil, vetiver oil, elemi oil, and lemon oil, creates a refreshing, comfortable, and natural feeling. The body and base notes, blended with specific directing agents and modifiers, enrich the fragrance with a vibrant, clear, and long-lasting aroma. Furthermore, through the complementary and synergistic effects of these ingredients, highly effective and synergistic purification of bacteria and formaldehyde is achieved. These products have broad application prospects in indoor air purification and health protection, providing strong support for creating a healthier and fresher indoor environment.

[0008] Specifically, lemon oil is rich in ingredients such as limonene, whose methyl and methylene groups are extremely active; rosemary oil contains phenolic acids such as rosmarinic acid and carnosic acid; the above active ingredients can effectively neutralize harmful gases such as formaldehyde, and play a good role in removing formaldehyde.

[0009] Furthermore, the combination of pine needle oil, eucalyptus oil, rosemary oil, vetiver oil, elemi oil, and lemon oil is not only beneficial for their individual direct formaldehyde conversion capabilities, but also for the complementary and synergistic effects of their components. The rich terpenes, alcohols, and aldehydes contained in pine needle oil, eucalyptus oil, vetiver oil, and elemi oil interact with the active ingredients in lemon and rosemary oils to form a comprehensive and complex system. For example, the limonene in lemon oil effectively enhances the penetration of phenolic acids in rosemary oil, allowing them to more easily reach the interior of bacterial cells or the tiny spaces where formaldehyde hides, thereby enhancing the overall antibacterial and formaldehyde-removing efficacy. At the same time, the 1,8-cineole in eucalyptus oil synergizes with the active ingredients in rosemary oil to significantly enhance the antibacterial effect by destroying bacterial cell walls and membranes, effectively reducing formaldehyde produced by bacterial metabolism. This unique system targets different types of bacteria and formaldehyde molecules, providing a more comprehensive and efficient purification effect.

[0010] Furthermore, the blend of active ingredients in this specialized system inhibits bacterial metabolism by disrupting their respiratory or enzyme systems, thereby curbing their growth and reproduction and reducing the risk of bacterial resistance. Regarding formaldehyde removal, the active ingredients in the essential oils not only chemically react with formaldehyde, converting it into harmless substances, but also, through adsorption, securely lock formaldehyde molecules within the oil, effectively reducing indoor formaldehyde concentrations.

[0011] The fragrance composition with formaldehyde removal function provided in this application not only retains the aroma characteristics of traditional fragrances, but also combines specific formaldehyde removal ingredients. It can effectively decompose and remove formaldehyde molecules in the air while emitting a pleasant aroma, thereby providing consumers with an indoor environment that is both fragrant and healthy.

[0012] Adding the formaldehyde-removing fragrance composition of this application to solid products such as ointments, flameless incense, and scented paper sheets can significantly improve the formaldehyde-removing efficacy of the products, increase the added value of the products, and meet the modern people's pursuit of quality of life. Compared with commonly used aromatherapy products on the market, this formaldehyde-removing fragrance composition not only improves air quality by volatile aroma, but also solves the formaldehyde pollution problem at the source, providing consumers with a safer, healthier, and more environmentally friendly lifestyle choice.

[0013] Preferably, according to the mass percentage of the essence composition with formaldehyde removal function, vetiver oil is 0.1-0.2%, elemi oil is 0.1-0.5%, lemon oil is 3-5%, pine needle oil is 5-8%, eucalyptus oil is 3-5%, and rosemary oil is 5-8%.

[0014] By adopting the above technical solution, the dosage and coordination effect of pine needle oil, eucalyptus oil, rosemary oil, vetiver oil, elemi oil, and lemon oil in the system are further limited, so that the effective active ingredients among the six can play a more sufficient synergistic role, thereby enhancing the effect of removing formaldehyde and also improving the stability of the composition.

[0015] Preferably, the solvent comprises a mixture of one or more of isopropyl myristate and dipropylene glycol.

[0016] Preferably, the solvent is isopropyl myristate and dipropylene glycol. According to the mass percentage of the flavor composition with formaldehyde removal function, isopropyl myristate is 1-5%, and dipropylene glycol is 35-45%.

[0017] By adopting this technical solution, the types and dosages of solvents can be further limited, achieving a better dispersion of pine needle oil, eucalyptus oil, rosemary oil, vetiver oil, elemi oil, and lemon oil within the system, allowing for more complete dispersion in downstream solid aromatherapy products. During subsequent use, the active ingredients volatilize effectively and are more readily exposed to and react with formaldehyde molecules, helping to convert the formaldehyde into harmless or less toxic substances.

[0018] Isopropyl myristate and dipropylene glycol can also effectively protect the active ingredients in pine needle oil, eucalyptus oil, rosemary oil, vetiver oil, elemi oil, and lemon oil from oxidation and decomposition, thereby extending the shelf life of the fragrance composition. Furthermore, these two solvents can optimize the physical properties of the fragrance composition, such as texture and fluidity, reducing stratification and precipitation, ensuring uniform and stable quality during storage and use. Furthermore, this specific solvent system can enhance the compatibility of the ingredients in pine needle oil, eucalyptus oil, rosemary oil, vetiver oil, elemi oil, and lemon oil, promoting intermolecular interactions and making the fragrance system more stable and harmonious.

[0019] Preferably, the fixative comprises a mixture of one or more of musk deodorant, synthetic oakmoss, and cashmeran.

[0020] Preferably, the fixative is musk deodorant, synthetic oak moss, and cashmeran. According to the mass percentage of the fragrance composition with formaldehyde removal function, musk deodorant is 1-5%, synthetic oak moss is 0.1-1%, and cashmeran is 1-5%.

[0021] Preferably, the modifier comprises a mixture of one or more of methyl cedryl ketone and methyl dihydrojasmonate.

[0022] Preferably, the modifier is methyl cedryl ketone and methyl dihydrojasmonate. According to the mass percentage of the fragrance composition with formaldehyde removal function, methyl cedryl ketone is 1-5%, and methyl dihydrojasmonate is 1-3%.

[0023] By adopting the above technical solution, the specific types of main fragrance, fixative and modifier are further limited, giving the fragrance a comfortable and refreshing aroma, and improving the overall quality and stability of the fragrance.

[0024] In summary, this product boasts a rich, refreshing, and pleasant aroma. The top note, a scientifically formulated blend of camphor, vetiver oil, elemi oil, lemon oil, pine needle oil, eucalyptus oil, and rosemary oil, evokes a refreshing, soothing, and natural feeling, as if transported to a lush forest. The body note, a blend of methyl dihydrojasmonate, cashmeran, and synthetic oakmoss, enriches the fragrance with a vibrant and dynamic character. The addition of cashmeran adds a richer, sweeter aroma. The base note, a blend of toniferum, methyl cedarwood ketone, and ambergris, creates a clear, long-lasting woody aroma.

[0025] In a second aspect, the present application provides a method for preparing a fragrance composition having formaldehyde removal function, using the following technical solution:

[0026] A method for preparing a fragrance composition with formaldehyde removal function comprises the following steps:

[0027] Step 1: Dissolve various raw materials separately in a water bath;

[0028] Step 2: Mix the raw materials dissolved in a water bath and mix them at 800-1200 r / min until uniform;

[0029] Step 3: Aging for 18-26 hours to obtain a fragrance composition with formaldehyde removal function.

[0030] In summary, this application has the following beneficial effects:

[0031] 1. The top note of this product is made of camphor, vetiver oil, elemi oil, top-grade lemon oil, pine needle oil, eucalyptus oil, and rosemary oil, which are scientifically blended. It gives people a fresh, comfortable, and natural feeling, as if they are in a lush forest. The body fragrance is made of methyl dihydrojasmonate, cashmeran, and synthetic oakmoss, which makes the fragrance richer and more lively, and the embellishment of cashmeran makes the fragrance more intense and sweet. The base note is made of musk denatonium, methyl cedarwood ketone, and ambergris, which makes the woody fragrance clear and lasting.

[0032] 2. This application can effectively neutralize harmful gases such as formaldehyde through the synergistic effect of pine needle oil, eucalyptus oil, rosemary oil, vetiver oil, elemi oil, and lemon oil, destroy the cell walls and cell membranes of bacteria, and effectively reduce the formaldehyde produced by bacterial metabolism. It has a good formaldehyde removal effect in indoor environmental purification and creates a healthier and fresher living environment for users.

[0033] 3. The preferred solvents used in this application are isopropyl myristate and dipropylene glycol, which effectively protect the active ingredients of pine needle oil, eucalyptus oil, rosemary oil, vetiver oil, elemi oil, and lemon oil from oxidation and decomposition, thereby extending the shelf life of the fragrance composition. Furthermore, the physical properties of the fragrance composition are optimized, reducing the occurrence of stratification and precipitation, enhancing the compatibility of the essential oil components, and promoting intermolecular interactions, resulting in a more stable and harmonious fragrance system.

[0092] Performance testing

[0093] 1. Formaldehyde removal detection:

[0094] In a 1.5 cubic meter transparent sealed container, the temperature is adjusted to 21°C and the humidity is 55%.

[0095] 350 grams of the fragrance composition with formaldehyde removal function is placed in a transparent sealed container.

[0096] Formaldehyde was injected into a transparent sealed container with a formaldehyde concentration of 1.02 mg / m3.

[0097] Store in the presence of light for 24 hours.

[0098] After 24 hours, measure the remaining formaldehyde concentration and calculate the formaldehyde removal percentage according to the following formula.

[0099] Formaldehyde removal percentage = (initial formaldehyde concentration - residual formaldehyde concentration) / initial formaldehyde concentration

[0100] The results are recorded in Table 2.

[0101] 2. Stability: The fragrance composition with formaldehyde removal function was stored at 50°C and 95% humidity for 30 days.

[0102] After removal, formaldehyde removal test was performed again, and the percentage of formaldehyde removal was recorded in Table 2.

[0103] 3. Fragrance evaluation: 10 experienced scent masters were selected to evaluate the fragrance composition with formaldehyde removal function using the "Qingqi Ru Nis" method. The number of people who thought it had "peculiar smell or was very unpleasant" was recorded in Table 2.

[0104] Table 2

[0105]

[0106]

[0107] According to the test data in Table 2, the fragrance compositions with formaldehyde removal function of Examples 1-5 and Comparative Examples 1-7 have no peculiar smell, are pleasant to the touch, and have a fresh and pleasant smell.

[0108] The flavor compositions with formaldehyde removal function of Comparative Examples 1-6 are based on Example 1, with pine needle oil, eucalyptus oil, rosemary oil, vetiver oil, elemi oil, and lemon oil replaced by other oils; Comparative Example 7 is based on Example 1, with lemon oil being the only vegetable oil.

[0109] According to the formaldehyde removal test in Table 2, although the fragrance compositions with formaldehyde removal function of Examples 1-5 and Comparative Examples 1-7 all have a certain formaldehyde removal effect, a comparison shows that the formaldehyde removal percentages of the fragrance compositions with formaldehyde removal function of Examples 1-5 are all above 86%, while the formaldehyde removal percentages of the fragrance compositions with formaldehyde removal function of Comparative Examples 1-7 are only between 70-80%, which is significantly inferior to that of Examples 1-5.

[0110] Furthermore, regarding stability, the formaldehyde removal percentages of the formaldehyde-removing fragrance compositions of Examples 1-5 remained similar to pre-storage levels after being stored under high temperature and high humidity conditions for a period of time, with little change in formaldehyde removal testing. This demonstrates that the formaldehyde-removing fragrance compositions of Examples 1-5 possess excellent stability. However, the formaldehyde-removal percentages of the formaldehyde-removing fragrance compositions of Comparative Examples 1-7 were lower in the stability test, showing a significant decrease compared to pre-storage levels, indicating poor stability and not as good as that of Examples 1-5.

[0111] In Comparative Examples 1-7, when the specific combination of pine needle oil, eucalyptus oil, rosemary oil, vetiver oil, elemi oil, and lemon oil was subjected to varying degrees of deterioration, the resulting formaldehyde-removing fragrance composition failed to effectively remove formaldehyde and also had poor stability. This demonstrates that the specific combination of pine needle oil, eucalyptus oil, rosemary oil, vetiver oil, elemi oil, and lemon oil is essential.

[0112] Examples 4-5, based on Example 1, adjusted the type and amount of solvents used. Although Examples 4-5 were still superior to Comparative Examples 1-7, they were slightly inferior to Example 1. This suggests that further limiting the specific type and amount of solvents can further enhance the combined effects of pine needle oil, eucalyptus oil, rosemary oil, vetiver oil, elemi oil, and lemon oil, thereby improving performance.

[0113] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
