Description

Technical Field

[0001] This invention relates to the field of air purification technology, specifically to an indoor nicotine elimination compound formula, its preparation method, and its application. Background Technology

[0002] Smoking is prevalent in indoor environments, whether in homes, offices, or public entertainment venues such as internet cafes and card rooms. The smoke produced by cigarettes contains a large amount of nicotine, which adheres to tiny particles in the air and spreads throughout the room with airflow, also accumulating on furniture surfaces, fabric fibers, and walls. Prolonged exposure to such an environment means that nicotine is continuously released into the air, causing serious harm to human health. Studies have shown that nicotine irritates the respiratory mucosa, triggering symptoms such as coughing and wheezing, increasing the risk of respiratory diseases; it also affects the cardiovascular system, leading to increased blood pressure and heart rate, increasing the incidence of heart disease and stroke.

[0003] Currently, there are various products and methods available on the market for eliminating indoor nicotine. Air purifiers are a common example, primarily removing nicotine and other pollutants from the air through filtration and adsorption. However, air purifiers are relatively expensive, and their filters require regular replacement, increasing operating costs. Furthermore, some air purifiers can only purify the air in a localized area, offering limited effectiveness in eliminating nicotine from an entire room.

[0004] Chemical smoke removers are also a common method, as they can quickly remove smoke odors. However, some chemical smoke removers contain harmful chemicals such as benzene and formaldehyde. Long-term use of these chemical smoke removers can leave harmful substances indoors, causing secondary harm to human health.

[0005] There are also some natural plant-based smoke-removing products that mainly use the aroma of plant essential oils to mask the smell of smoke. However, most of these products rely solely on the masking effect of essential oils and are not very effective at eliminating nicotine, thus failing to fundamentally solve the problem of indoor nicotine pollution.

[0006] Therefore, developing a low-cost, safe, and effective compound formulation for eliminating indoor nicotine is of great practical significance. Summary of the Invention

[0007] The purpose of this invention is to provide an indoor nicotine elimination compound formula, its preparation method, and its application. This formula consists of natural plant essential oils, tea polyphenols, activated carbon powder, solvents, and optional auxiliary ingredients. Through the synergistic effect of multiple components, it can efficiently adsorb and decompose nicotine in the air, while simultaneously improving the indoor odor environment.

[0008] This invention proposes an indoor nicotine elimination compound formula, its preparation method, and its application. The compound formula is scientifically formulated from a variety of natural plant extracts and functional ingredients. Lemon oil, lavender oil, and linalool, as a natural essential oil system, work synergistically through their unique chemical components to both mask smoke odor and chemically react with nicotine, disrupting its molecular structure. Tea polyphenols, as the core adsorption and decomposition component, contain active substances such as EGCG that effectively capture and degrade nicotine, while activated carbon powder further removes nicotine molecules from the air through physical adsorption. Deionized water is used as a solvent to ensure uniform dispersion of all components. The optional ingredient menthol, added in the range of 0.2%-1.5%, adjusts the aroma intensity while providing a cooling sensation and enhancing the user experience. The mass percentages of each component have been repeatedly verified through experiments to ensure optimal purification effect at low cost. This formula, through the organic combination of natural plant ingredients and functional materials, overcomes the limitations of traditional air purification products that rely on a single mechanism. Lemon oil contains d-limonene, which has strong oxidizing properties and can accelerate the chemical decomposition of nicotine; lavender oil contains α-pinene, which reduces the volatility of nicotine through physical encapsulation; and tea polyphenols, through their dual action (adsorption + decomposition), significantly improve purification efficiency. Activated carbon powder has a high specific surface area (≥1200m²). 2 The combination of g / g and a suitable particle size (200-400 mesh) allows it to achieve maximum adsorption capacity with limited dosage. Furthermore, the synergistic effect of the components in the formulation enables the product to maintain highly efficient purification while avoiding the risk of chemical residues, making it particularly suitable for homes and medical settings where safety requirements are high.

[0009] Furthermore, the lemon oil is a natural essential oil extracted from the peel of citrus fruits (Citrus spp.), with d-limonene as its core component. This component is chemically reactive and can break down the benzene ring structure of nicotine through oxidation, converting it into harmless small molecule compounds. The concentration of d-limonene directly affects the purification efficiency of the formula; therefore, it must be derived from high-quality citrus peels and purified through distillation to retain its active ingredients. The strong oxidizing properties of d-limonene make it a key component in breaking down nicotine. Compared to other plant essential oils, lemon oil exhibits significant catalytic activity even at lower concentrations, and its refreshing fruity aroma effectively neutralizes smoke odors, improving the indoor environment. In addition, the biodegradability of natural lemon oil avoids secondary pollution, meeting environmental protection requirements.

[0010] Furthermore, lavender oil is extracted from the inflorescence of plants in the genus *Lavandula* of the Lamiaceae family, and its α-pinene content must be ≥35%. α-Pinene is a natural monoterpene compound that can bind to nicotine molecules through an addition reaction, reducing its free state in the air. Lavender oil not only provides a pleasant aroma, but its calming effect can also alleviate the irritation caused by smoking environments. The physical encapsulation effect of α-pinene slows down the evaporation rate of nicotine, prolonging the duration of action of the formulated ingredients. The low volatility of lavender oil allows it to maintain a stable aroma output during long-term storage, making it suitable for commercial spaces requiring continuous air purification. In addition, lavender's natural antibacterial properties can inhibit bacterial growth, indirectly improving air quality.

[0011] Furthermore, linalool, as a terpene compound, requires an optical purity of ≥98%. High-purity linalool ensures aroma harmony in formulations and promotes nicotine breakdown through weak interactions with nicotine molecules. Linalool's chemical stability allows it to optimize both functionality and sensory experience in formulations. Linalool with an optical purity of ≥98% avoids interference from isomers on purification effects, while its gentle woody aroma forms a layered fragrance combination with lemon and lavender oils, meeting personalized needs in different scenarios. In addition, linalool's antibacterial activity synergizes with other ingredients in the formulation, further improving air hygiene levels.

[0012] Furthermore, tea polyphenols are mainly composed of catechin compounds, with EGCG (epigallocatechin gallate) content ≥40%. EGCG, as a potent antioxidant, can not only directly chelate with nicotine but also inhibit its biological activity, reducing damage to the human cardiovascular system. A high EGCG content significantly enhances the formulation's chemical adsorption capacity; its multi-hydroxyl structure can form a hydrogen bond network, firmly capturing nicotine molecules. Experimental data shows that tea polyphenols with an EGCG content ≥40% can increase the nicotine decomposition rate by more than 30%, and its safety has been certified by food safety standards, making it suitable for food contact applications.

[0013] Furthermore, the activated carbon powder must have a specific surface area ≥1200m². 2 / g, particle size distribution 200-400 mesh. High specific surface area provides ample adsorption sites, while the moderate particle size ensures uniform dispersion in solution, preventing sedimentation. The porous structure of activated carbon can physically trap nicotine molecules, extending purification time. Specific surface area ≥1200m² 2 The activated carbon powder at / g exhibits an adsorption efficiency exceeding 90% for particles larger than 0.3μm, effectively removing suspended nicotine particles from the air. Its 200-400 mesh particle size distribution prevents clumping during stirring, ensuring the fluidity and stability of the solution. This specification of activated carbon strikes a balance between cost and performance, making it suitable for large-scale industrial production.

[0014] Furthermore, the preparation method includes the following key steps: a) Pretreatment of deionized water at a constant temperature of 25±2℃ to avoid temperature fluctuations affecting the activity of the components; b) Adding tea polyphenols and activated charcoal powder sequentially while stirring at 200-300 r / min, and continuing stirring for 40-60 minutes to ensure thorough mixing; c) Adjusting the stirring speed to 250-350 r / min, slowly adding lemon oil, lavender oil, linalool, and menthol, and continuing stirring for 30-40 minutes to prevent loss of essential oils through evaporation; d) After standing for 1-2 hours, filtering using a 0.45μm microporous membrane to remove undissolved particles; e) Filling the filtrate into gamma-ray sterilized glass bottles and sealing for storage. The gradient stirring process (200-300 r / min to 250-350 r / min) effectively avoids the aggregation of high-viscosity components, ensuring uniform dispersion of each component. 0.45μm membrane filtration can retain 99.9% of microorganisms and impurities, improving product purity. Gamma ray sterilization technology enables aseptic filling without introducing chemical residues, ensuring product safety.

[0015] Furthermore, in step b), the temperature at which tea polyphenols are added needs to be controlled at 18-22℃, and the feeding rate of activated carbon powder is 50-80 g / min. Temperature control prevents the oxidation and deactivation of tea polyphenols, while the feeding rate ensures their complete dissolution in deionized water. The low-temperature environment of 18-22℃ maintains the chemical stability of tea polyphenols, avoiding degradation of active ingredients caused by high temperatures. The feeding rate of 50-80 g / min ensures uniform dispersion of activated carbon powder, preventing precipitation problems caused by excessively high local concentrations. This combination of parameters ensures that the formulation remains uniform throughout the preparation process, improving the efficiency of mass production.

[0016] Furthermore, the compound formula is formulated into a spray, which is applied at a rate of 3-6 ml / m² in indoor areas with a smoky smell. 2 Apply the spray using a fine mist spray, maintaining a ventilation rate of 0.3-0.5 m / s after spraying. The atomized particle diameter of the spray should be controlled within 5-10 μm to ensure uniform coverage of the target area by the active ingredient. 3-6 ml / m 2 The dosage has been experimentally verified to reduce local nicotine concentration by more than 60% within 10 minutes. A ventilation rate of 0.3-0.5 m / s accelerates solvent evaporation while avoiding excessive dilution of the active ingredient. The 5-10 μm atomized particles penetrate deep into fabric fibers and furniture surfaces, removing adsorbed nicotine and achieving deep purification.

[0017] Furthermore, the compound formulation is injected into an open container and heated to 10-20m. 2 Within the space, apply 0.5-1.0 g / m³. 3The dosage is allowed to evaporate naturally. Maintain an ambient humidity of 40%-60% during use. Avoid direct sunlight during the evaporation process to prevent degradation of photosensitive components. 0.5-1.0 g / m³ 3 The dosage design balances purification efficiency and economy, with a single application providing continuous protection for 4-6 hours. Ambient humidity of 40%-60% activates the antioxidant activity of tea polyphenols, increasing their decomposition rate. This application method is suitable for open spaces such as living rooms and conference rooms, allowing users to achieve all-day air purification without complicated operations.

[0018] The beneficial effects of this invention are:

[0019] The indoor nicotine elimination compound formula and its application scheme provided by this invention achieve efficient degradation of nicotine and improved environmental friendliness through the synergistic effect of multiple components. Firstly, the natural plant essential oils (lemon oil, lavender oil, and linalool) used in the formula not only give the product a pleasant aroma, but their active ingredients can also chemically react with nicotine, destroying its molecular structure. For example, d-limonene in lemon oil has strong oxidizing properties, which can promote the oxidative decomposition of nicotine into harmless substances; α-pinene in lavender oil reduces the volatility of nicotine through an addition reaction. Secondly, tea polyphenols, as natural antioxidants, can not only physically adsorb nicotine molecules, but their EGCG component can also inhibit the biological activity of nicotine, reducing its toxic effects on the human body. The addition of activated carbon powder further enhances the adsorption capacity, with its high specific surface area (≥1200m²). 2 The particle size distribution of 200-400 mesh (g / g) ensures effective capture of fine particulate matter. Furthermore, the proportions of each component in the formulation have been optimized; the ratio of lemon oil (6%-9%), lavender oil (4%-7%), and linalool (3%-6%) has been experimentally verified to maximize decomposition efficiency while maintaining aroma harmony.

[0020] In terms of preparation method, this invention employs a gradient stirring process (initially increasing the rotation speed from 200-300 r / min to 250-350 r / min), combined with staged feeding (first adding tea polyphenols and activated carbon powder, then adding essential oil components), effectively avoiding agglomeration between components and ensuring the uniformity and stability of the solution. Precision filtration through a 0.45 μm microporous membrane further removes any potential impurities, improving the purity of the product. In terms of application, this invention offers flexible usage: the spray formulation is suitable for rapid treatment of locally high-concentration polluted areas (3-6 ml per square meter), while the open container evaporation method is suitable for long-term maintenance of spatial air quality (one container per 10-20 square meters). Experimental data shows that after spraying 25 ml of solution in a closed room, the nicotine concentration decreased from 2.8 mg / m³. 3 Reduced to 0.4 mg / m³ 3It only takes 40 minutes and still maintains significant effects in complex environments such as card rooms.

[0021] Compared to existing technologies, the core advantages of this invention are: 1) It avoids the risk of chemical residues through the combination of natural ingredients, aligning with the concept of health and environmental protection; 2) The synergistic effect of multiple mechanisms (adsorption, decomposition, and masking) achieves comprehensive elimination of nicotine; 3) The preparation process is simple and controllable, with low raw material costs (the main components are commercially available food-grade raw materials), facilitating large-scale production; 4) It has a wide range of applications, suitable for both daily household purification and centralized treatment needs in commercial settings. Example tests show that this formula, in a 20-square-meter chess and card room, only requires spraying 60ml of solution to reduce the nicotine concentration from 3.8mg / m² within 1.5 hours. 3 Reduced to 0.6 mg / m³ 3 Furthermore, it leaves no irritating odor residue. In summary, this invention provides an efficient, safe, and economical innovative solution for indoor nicotine pollution control. Detailed Implementation
