1. Nicotine from tobacco should be used with a purity of not less than 99%Nicotine is what we call nicotine. Currently, there are two sources of nicotine, which are extracted from tobacco leaves (or other plants) and chemically synthesized. Simply put, the extraction of nicotine means using chemical solvents to extract the nicotine already present in tobacco leaves, and then separate and purify it; the synthesis method mainly uses other non-nicotine raw materials for chemical synthesis, and does not need to use tobacco leaves.At present, only a few domestic companies have the technology to synthesize nicotine on a large scale, and the nicotine in e-cigarettes on sale comes from tobacco extraction.From the perspective of chemical analysis and testing of the final finished nicotine product, as long as the purity reachesMore than 99% is obtained from which route it is produced, and the impact on subsequent e-cigarette finished products is negligible.# p#pagination title #e#The new national standard clearly stipulates that the source of nicotine is the extraction method, and the tobacco raw materials required for the extraction method are strictly controlled.In line with the State Council order issued a few days agoThe core idea of "e-cigarettes are regulated with reference to traditional tobacco" is consistent. This regulation has a positive impact on consumers because it has unified requirements for the main raw materials of new tobacco,But it could become a new tobacco companyThe "stuck neck" problem will increase the requirements for enterprises 'supply chain and production cost control. The upstream supply chain management and production quality assurance system will becomeOne of the core competencies of future new tobacco companies。Synthetic nicotine tobacco oil may be used more for export in the future.2. Benzoate, tartrate, lactate, levulinate, malate and citrate salts of nicotine are allowed #p#pagination title #e#Nicotine salts are the general term for salts formed by combining nicotine and different acids. All salts shown in the national standard regulations indicate the source of the acids that can be used in tobacco oil that combine with nicotine to form salts. Due to the different properties and spatial structure of these acids, their ability to combine with nicotine during the atomization process is different, bringing a different inhalation experience.As a new tobacco company, finding the right acid within the range allowed by the national standard and the corresponding ratio are also very critical to the product experience.3. Other tobacco extracts should meet the requirements for tobacco flavorsTobacco flavor refers to a flavor blended with two or more flavors and other ingredients to enhance the style of tobacco products or improve tobacco quality. The national standard has a series of quality control indicators and testing methods for tobacco flavors. this regulationFirst of all, it was clarified that tobacco extracts can be used in e-cigarettes, providing more possibilities for e-cigarettes to benchmark the original taste of tobacco.#p#Pagination Title #e#4.& nbsp; Aerosol additives should not give the product a characteristic flavor that is tempting to minorsThis article puts forward one of the main needs for the development of tobacco oil technology, that is, to eliminate multiple flavors, allow e-cigarettes to benchmark with the original flavor of tobacco, and reduce the characteristics that are potentially attractive to minors from the perspective of the product itself.5. The nicotine concentration in the aerosolized substance should not exceed 20mg/g, and the total amount of nicotine should not exceed 200mg. Nicotine release should not exceed 0.2mg/puffNicotine concentration: The nicotine concentration of e-cigarette products corresponding to this regulation is2%, lower than the nicotine content in most cigarettes on the market, but slightly higher than the EU standard1.7%。After the introduction of the national standard regulations, all manufacturers will reduce the nicotine content of tobacco oil on sale, which may cause problems of insufficient detoxification. thereforeAchieving the best detoxification effect within the specified nicotine concentration range will become the core competitiveness of the manufacturer.# p#pagination title #e#Total amount of nicotine: The total amount of nicotine in a single cigarette is required to be no higher than200mg。Calculated based on the highest possible nicotine concentration of 20mg/g, a single cigarette cartridge should not exceed 200mgThe total amount of nicotine, i.e., a single cigarette cartridge cannot contain more than200/20=10g tobacco oil. According to the general specifications of closed small cigarettes (1-2gtobacco oil content)，The total amount of nicotine is much lower than the national standardEven if some brands subsequently plan to launch larger-capacity cigarettes, the total nicotine content will not exceed national standards. On the other hand, considering the possibility that the cigarette cartridge may be accidentally damaged, resulting in passive and direct contact with the smoke from the user's mouth, esophagus or other skin areas,The total limit of 200mg can also control the amount of nicotine a user can directly contact or swallow in a single time and avoid nicotine poisoning.Nicotine release: Since the e-cigarette liquid is heated and atomized into an aerosol for users to inhale, the final end product of the e-cigarette is an aerosol, and the amount of nicotine in the cigarette liquid cannot directly benchmark the amount of nicotine inhaled by users. Therefore, the national standard also stipulates the nicotine content in the aerosol. For all e-cigarette products, relevant testing should be carried out on the aerosol generated when the product is used in accordance with the national standard regulations to confirm that the nicotine in the aerosol does not exceed each inhale.0.2 mg to meet the specified standards. At the highest nicotine concentration of 20mg/gand the highest possible atomization efficiency100%To estimate, in the national standard test parameters per #p#pagination title #e#Under the condition of taking a puff for 30 seconds and inhaling 55mL per puff, the product under test is required to have an average of no more than 10mg of atomized tobacco oil per puff. At present, the average atomized tobacco oil per puff of conventional closed small cigarettes is 3-5mg, so this requirementIt also limits the possibility of the product using high power to increase nicotine delivery.6. E-cigarette products should be marked with:a) List of aerosol components, in descending order of mass fraction, with the lowest being 0.1%;b) The concentration of nicotine in the aerosol and the total amount of nicotine are expressed in "mg/g" and "mg" respectively;c) The volume of e-cigarette liquid or the mass of solid aerosol, expressed in "mL" and "g" respectively;d) Restriction signs for the use of hazardous substances in electronic and electrical products shall comply with SJ/T 11364;#p#Page Title #e#e) Health warnings shall comply with relevant regulations of relevant national administrative departments.There have been further regulations on industry packaging and information disclosure, and industry transparency has increased.The labeling requirements for the ingredient list are aligned with the EU TPD requirements.7. Provisions for temporary licensing of substances for aerosol additivesThis table stipulatesList of 122 temporarily licensed substances for aerosol additives and maximum usage quantities, there are clear specifications for the use of additives. The safety of the additives in the table has been confirmed at home and abroad, and have been widely used in the food field. These additives can be roughly divided into natural flavors (such as lemon oil, rose oil and rosemary oil), synthetic flavors (esters, aldehydes, ketones, etc.), extracts (coffee extract, cocoa extract), acids used to form nicotine salts (such as #p#pagination title #e#2) and preservatives (potassium sorbate) are the source of different flavors of e-cigarette products.The types and dosage regulations in the national standard not only provide consumers with more diversified products, but also ensure product safety.Restricting some irresponsible brands from launching snacks to tastes at willThis results in unnecessary attraction to minors and lays the foundation for the sustainable development of the industry.8. Interpretation of test requirements for known hazards that may be contained or generated by aerosolized substancesThe national standard stipulates the determination of the release amounts and determination methods of three aldehydes and butanediones in e-cigarette emissions (aerosols). These aldehydes and butanedione are harmful substances known to cause long-term irreversible diseases such as cancer and popcorn lungs. This national standard regulation puts forward requirements for product quality control of e-cigarette manufacturers. Not only should they not actively add butanedione as a flavoring agent for margarine flavors, they also require high standards of control over the atomization temperature of the product to prevent excessive heating of cigarette oil. Produce a large amount of aldehyde by-products. After the introduction of the national standard, consumers can be more assured of the quality of the products they purchase. #p#Pagination Title #e#9. When pressure occurs inside the e-cigarette smoking set due to battery failure, the pressure relief direction should be opposite to the suction direction, and the nozzle should be free from damage or displacement.In some extreme cases, e-cigarette batteries may fail, expand, etc. At this time, the user's personal safety needs to be guaranteed. Therefore, the new national standard requires brands to rethink the placement and assembly of the internal structure of the product when designing e-cigarettes in the future, and set pressure relief holes at the tail far away from the nozzle.10. E-cigarette smoking sets should have child-proof starting functions and protective functions to prevent accidental startingAt present, most e-cigarettes on the market are relatively simple to operate. They can be activated by putting them directly into the mouth and inhaling them. When parents are not paying attention, children may accidentally activate e-cigarettes, inhale them by mistake, etc. Therefore, the new national standard requires tobacco rods to add functions to prevent children from starting and protective functions to prevent accidental starting. For example, the operating steps for starting the tobacco rods are set to be more complicated. Relevant instructions on child protection functions should also be added to the instructions. #p#Pagination Title #e#The national standard as a whole is conducive to the healthy development of the industry, promoting the e-cigarette industry to continue to increase investment in scientific research, fulfill its social responsibilities, and contribute to the healthy development of the industry. Encourage with practitioners.
