How to Minimize Vaping Aerosols' Threat to Users' Safety

What Are Vaping Aerosols?

E-cigarettes have been popular as tobacco substitutes for many years; in simple terms, they are battery-powered devices that work by heating a liquid into an aerosol that the user inhales and exhales, which is also described as atomization. These aerosols are deposited and absorbed by the human respiratory system. Therefore, preventing harmful chemicals from entering the human body with aerosolized vapors is a significant research field in the vaping industry.

The Safety Threats of Atomization Mechanisms

1. Harmful Substance Generated During Atomization

In research published by Herrington and Myers (2015), approximately 60 to 70 compounds (unidentified and identified) were detected in each e-liquid tested. When the e-liquid is heated to an extremely high temperature, those compounds can be transformed into a wide variety of chemical components in the resulting aerosols.

Unfortunately, those chemicals could include heavy metal elements or other harmful substances. Those harmful particles would, together with aerosol vapors, flow into the human body.

2. Ceramic Coil Silica Dust Release

Two of the market's mainstream coil options are ceramic and cotton. Ceramic coils have several notable advantages, such as a long lifespan, no dry hits, and smoother taste. However, a major issue associated with ceramic coils is the unavoidable release of silica dust, which potentially has serious implications for users' health and safety. Considering this, ALD developed an advanced cotton coil technology platform, which provides high flavor consistency, better nicotine satisfaction, and safer vapor. Following thousands of experiments conducted by ALD during the development process, it was shown that carbonyls and heavy metal emissions from aerosols declined below the safe level.

The Solution to Creating Safer Vaping Aerosols

ALD has a deep commitment to the ongoing development of safer vaping solutions, aiming always to be at the forefront of a rapidly evolving industry. Naturally, minimizing the risks of vaping aerosols is a key area of focus.

1. Consistent Technology Improvement

ALD's research institute is continuously working on technological improvements in e-liquid development. In addition, enhancing the temperature control technology is also critical, as precise control will help guarantee that aerosols are generated without toxic chemicals.

2. Selecting the Most Appropriate Coil

As noted above, two mainstream coil types are ceramic and cotton, and there are significant 'pain points' of potential health risks associated with ceramic coils.

As a strong and viable alternative to ceramic coils, ALD offers cutting-edge cotton coil technology. Developed through a rigorous testing process, this technology creates a cleaner aerosol where the harmful substance emissions of the vapor are decreased to safe levels.

3. ALD's Vapor Safety Principle

ALD prioritizes users' safety. Our research institute conducted thousands of quantitative analyses on vapor aerosol, especially focusing on the avoidance of harmful substances, including aryl ketone, methanol, ethanol, and so on, to ensure that it would not hurt the human body. In addition, with specific reference to regulatory requirements such as TPD, AFNOR, and PMTA, ALD has developed its own robust vapor safety standards in order to confidently provide users with a fabulous vaping experience without health or safety threats.

The security of e-cig devices has always been a priority for the vaping industry. They carry a small fraction of the risk of cigarettes; although e-liquid and vapor contain some potentially harmful chemicals also found in cigarette smoke, they are at much lower levels. As tobacco substitutes, e-cig products will undoubtedly thrive in the tobacco markets in the coming years.
