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 much attention due to its significant harm to human health. It may not only come from home decoration materials, new furniture, floors and various adhesives, but may also be hidden in certain daily consumer products, such as cosmetics, detergents and certain textiles. Long-term exposure to formaldehyde environment may cause irritation to the eyes, skin and respiratory tract, causing headaches, nausea, coughing and other discomfort symptoms, and in severe cases may even increase the risk of cancer. Therefore, developing effective formaldehyde removal technology to reduce formaldehyde concentrations in living and working environments has become an important issue in protecting public health.

[0003] Traditional space fragrance products, such as aromatherapy and air fresheners, have shown some effects in removing bad odors, toxic chemicals and toxic gases from the air, but their main mechanism of action is to cover up the odor in the air through the volatilization of fragrances, rather than fundamentally decomposing or removing harmful substances such as formaldehyde and bacteria. Although these products can temporarily improve indoor air quality, they cannot provide a lasting and good formaldehyde removal effect, nor can they meet consumers' higher pursuit of healthy and environmentally friendly life.

[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 scheme: a fragrance composition with formaldehyde removal function, comprising the following components in terms of mass percentage: 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 the above technical scheme, the top fragrance part, with the cooperation of pine needle oil, eucalyptus oil, rosemary oil, vetiver oil, elemi oil and lemon oil, brings people a fresh, comfortable and natural feeling. The body fragrance and tail fragrance are formulated by specific directional agents and modifiers, making the fragrance richer and more flexible, clear and lasting. On the other hand, through the complementarity and synergy of various components, efficient and coordinated purification of bacteria and formaldehyde is achieved. They have broad application prospects in the field of 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] Moreover, the mixed use of pine needle oil, eucalyptus oil, rosemary oil, vetiver oil, elemi oil, and lemon oil lies not only in their respective direct conversion capabilities to formaldehyde, but also in the complementarity and synergy between their components. The rich terpenes, alcohols, and aldehyde compounds contained in pine needle oil, eucalyptus oil, vetiver oil, and elemi oil interact with the active ingredients in lemon oil and rosemary oil to form a broad and complex system. For example, limonene in lemon oil can effectively promote the permeability of phenolic acids in rosemary oil, making it easier to reach the inside of bacterial cells or the tiny spaces where formaldehyde hides, thereby enhancing the overall antibacterial and formaldehyde removal efficiency; at the same time, 1,8-cineole in eucalyptus oil synergizes with the active ingredients in rosemary oil, significantly improving the antibacterial effect by destroying the cell walls and cell membranes of bacteria, and effectively reducing the formaldehyde produced by bacterial metabolism. This special system can provide a more comprehensive and efficient purification effect for different types of bacteria and formaldehyde molecules.

[0010] In addition, the mixed active ingredients in the special system also inhibit the metabolic process of bacteria by interfering with the respiratory chain or enzyme system of bacteria, thereby curbing the growth and reproduction of bacteria and reducing the risk of bacterial resistance. In terms of formaldehyde removal, the active ingredients in essential oils not only react chemically with formaldehyde to convert it into harmless substances, but also may lock formaldehyde molecules firmly in the oil through an adsorption mechanism, effectively reducing the concentration of indoor formaldehyde.

[0011] The fragrance composition with formaldehyde removal function provided in the present 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 fragrance composition with formaldehyde removal function of the present application to solid products such as perfume, fireless aromatherapy, and scented paper can significantly improve the formaldehyde removal effect of the product, increase the added value of the product, and meet the pursuit of modern people's quality of life. Compared with the commonly used aromatherapy products on the market, this fragrance composition with formaldehyde removal function not only improves the air quality by volatilizing the aroma, but also solves the formaldehyde pollution problem from the source, providing consumers with a safer, healthier and more environmentally friendly life 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 scheme, 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 the above technical solution, the types and dosages of solvents are further limited, so that pine needle oil, eucalyptus oil, rosemary oil, vetiver oil, elemi oil, and lemon oil can be better dispersed in the system and more fully dispersed in downstream solid aromatherapy products. When used later, the effective active ingredients have a good volatilization effect and are easier to contact and react with formaldehyde molecules, which helps to convert formaldehyde into harmless or low-toxic substances.

[0018] Isopropyl myristate and dipropylene glycol can also effectively resist the damage of oxidation, decomposition and other adverse factors to the active ingredients of pine needle oil, eucalyptus oil, rosemary oil, vetiver oil, elemi oil and lemon oil, thereby extending the shelf life of the flavor composition. In addition, these two solvents can also optimize the physical properties of the flavor composition, such as texture and fluidity, reduce the occurrence of stratification, precipitation and other phenomena, and ensure that the flavor maintains uniform and stable quality during storage and use. In addition, the specific solvent system can also enhance the fusion between the components of pine needle oil, eucalyptus oil, rosemary oil, vetiver oil, elemi oil and lemon oil, promote the interaction between molecules, and make the flavor system more stable and harmonious.

[0019] Preferably, the fixative comprises a mixture of one or more of musk de nata, 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 includes 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 flavor 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 agents, fixatives and modifiers 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 has a rich, fresh and pleasant fragrance. The top note is made of camphor, vetiver oil, elemi oil, lemon oil, pine needle oil, eucalyptus oil, and rosemary oil in a scientific ratio, giving people a fresh, comfortable, and natural feeling, as if they were in a lush forest. The body fragrance is made of methyl dihydrojasmonate, cashmeran, and synthetic oakmoss, making the fragrance richer and more agile; and the embellishment of cashmeran makes the fragrance more intense and sweet. The tail fragrance is made of musk tonkinensis, methyl cedarwood ketone, and ambergris, making the woody fragrance clear and lasting.

[0025] In a second aspect, the present application provides a method for preparing a fragrance composition having a formaldehyde removal function, using the following technical solution: A method for preparing a fragrance composition having a formaldehyde removal function comprises the following steps: Step 1: Dissolve various raw materials separately in a water bath; Step 2: Mix the raw materials dissolved in a water bath and mix them at 800-1200r / min until they are uniform; Step 3: Aging for 18-26 hours to obtain a fragrance composition with formaldehyde removal function.

[0026] In summary, this application has the following beneficial effects: 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 in a scientific ratio, giving 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, making the fragrance richer and more dynamic, 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, making the woody fragrance clear and lasting.

[0027] 2. This application can effectively neutralize harmful gases such as formaldehyde, destroy bacterial cell walls and cell membranes, and effectively reduce formaldehyde produced by bacterial metabolism through the synergistic effect of pine needle oil, eucalyptus oil, rosemary oil, vetiver oil, elemi oil, and lemon oil. It has a good formaldehyde removal effect in indoor environmental purification and creates a healthier and fresher living environment for users.

[0028] 3. In this application, isopropyl myristate and dipropylene glycol are preferably used as solvents, which effectively resist the damage of oxidation, decomposition and other adverse factors to the active ingredients of pine needle oil, eucalyptus oil, rosemary oil, vetiver oil, elemi oil and lemon oil, thereby extending the shelf life of the flavor composition. In addition, the physical properties of the flavor composition are optimized, the occurrence of stratification, precipitation and other phenomena is reduced, the fusion between the essential oil components is enhanced, the interaction between molecules is promoted, and the flavor system is more stable and harmonious.

[0067] Comparative Example 7 A flavor composition with formaldehyde removal function, which is different from Example 1 in that pine needle oil, eucalyptus oil, rosemary oil, vetiver oil and elemi oil are replaced by lemon oil.

[0068] Performance testing 1. Formaldehyde removal detection: In a 1.5 cubic meter transparent sealed container, the temperature is adjusted to 21°C and the humidity is 55%.

[0069] 350 grams of the fragrance composition with formaldehyde removal function is placed in a transparent sealed container.

[0070] Formaldehyde is injected into a transparent sealed container with a formaldehyde concentration of 1.02 mg / cubic meter.

[0071] Store in the presence of light for 24 hours.

[0072] After 24 hours, measure the remaining formaldehyde concentration and calculate the formaldehyde removal percentage according to the following formula.

[0073] Formaldehyde removal percentage = (initial formaldehyde concentration - residual formaldehyde concentration) / initial formaldehyde concentration The results are recorded in Table 2.

[0074] 2. Stability: The fragrance composition with formaldehyde removal function is stored at 50° C. and 95% humidity for 30 days.

[0075] After taking out, the formaldehyde removal test was performed again, and the formaldehyde removal percentage was recorded in Table 2.

[0076] 3. Fragrance evaluation: 10 experienced scent smellers were selected to evaluate the fragrance composition with formaldehyde removal function using the Fresh Nose Method. The number of people who thought it had "peculiar smell and was unpleasant" was recorded in Table 2.

[0077] Table 2 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 nose, and have a fresh and pleasant smell.

[0078] 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.

[0079] 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 have a certain effect of removing formaldehyde, it can be seen from the comparison that the percentage of formaldehyde removal of the fragrance compositions with formaldehyde removal function of Examples 1-5 is more than 86%, while the percentage of formaldehyde removal of the fragrance compositions with formaldehyde removal function of Comparative Examples 1-7 is only between 70-80%, which is obviously not as good as that of Examples 1-5.

[0080] Moreover, in terms of stability, the flavor compositions with formaldehyde removal function of Examples 1-5 were stored for a period of time under high temperature and high humidity conditions, and then formaldehyde removal tests were performed. The percentage of formaldehyde removal remained at a level similar to that before storage, with almost no change. This shows that the flavor compositions with formaldehyde removal function of Examples 1-5 have good stability. However, the flavor compositions with formaldehyde removal function of Comparative Examples 1-7 have a lower percentage of formaldehyde removal in the stability test, which has also decreased significantly compared to before storage, indicating that their stability is not good and is not as good as that of Examples 1-5.

[0081] When the specific combination of pine needle oil, eucalyptus oil, rosemary oil, vetiver oil, elemi oil and lemon oil was destroyed to different degrees in Comparative Examples 1-7, the obtained flavor composition with formaldehyde removal function could not achieve a good formaldehyde removal effect and had poor stability, indicating that the specific combination of pine needle oil, eucalyptus oil, rosemary oil, vetiver oil, elemi oil and lemon oil is indispensable.

[0082] While Examples 4-5 are based on Example 1, the types or dosages of the solvents are adjusted. Although Examples 4-5 are still better than Comparative Examples 1-7, they are slightly worse than Example 1. This indicates that if the specific types and dosages of the solvents can be further limited, the combination effects of pine needle oil, eucalyptus oil, rosemary oil, vetiver oil, elemi oil, and lemon oil can be more fully utilized, thereby improving the performance.

[0083] 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 modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
