ZeroCloud™ - The Future of Smoke-Free Vaping

What is ZeroCloud™

ZeroCloud™ is a proprietary invisible vapor technology developed by Hangsen. By optimizing the base liquid formulation, ZeroCloud™ reduces the formation of visible aerosol particles by more than 99.95% compared to conventional e-liquids, even under mouth-to-lung (MTL) vaping conditions.

How It Works

Innovation Through the E-liquid Reformulation

ZeroCloud™ takes a fundamentally different approach to vapor control. By restructuring the base liquid formulation and selectively substituting ingredients to produce visible aerosol during heating, it significantly lowers vapor output while fully preserving sensory satisfaction, including flavor intensity, throat hit, and nicotine delivery.

Why ZeroCloud™

In the early days of vaping, thick vapor was seen as a sign of power and satisfaction. But a segment of user expectations has quietly shifted. As vaping becomes more common in social and regulated settings, a growing number of users are seeking a more discreet experience, low visibility, and minimal disruption has become increasingly important.

The rise of nicotine pouches is the most compelling proof of this shift. These products, which produce no visible vapor and cause minimal disruption, have gained global popularity by meeting the growing demand for cleaner and more discreet nicotine delivery methods.

That’s why Hangsen developed ZeroCloud™, an advanced invisible vapor solution. It eliminates visible aerosol while preserving flavor, throat hit, and nicotine satisfaction.

While both ZeroCloud™ and nicotine pouches cater to the demand for discreet, smoke-free nicotine delivery, ZeroCloud™ offers a more complete and compelling experience. Inhalation provides faster nicotine absorption and a more familiar ritual for smokers, while also enabling a richer and fuller flavor experience that pouches can't match. For smokers, the familiar inhalation mechanism makes ZeroCloud™ products a more intuitive and accessible alternative.

Technical Highlights

1. Zero Visible Vapor in MTL Mode

Lab tests conducted under standardized MTL conditions demonstrate that ZeroCloud™ reduces the visible aerosol output by over 99.95% compared to traditional e-liquids, resulting in a nearly invisible vapor experience. 

Internal lab testing followed ISO/TR 20768:2018 puffing conditions, with results compared to a baseline 50VG e-liquid.

2. Lower Toxicological Risk and Secondhand Impact

Experimental toxicology tests showed a consistent reduction in cell inhibition rates for both ZeroCloud™ e-liquid and its aerosol emissions, indicating a lower cytotoxic profile compared to conventional e-liquids. 

In addition, vape devices using ZeroCloud™ e-liquid generate extremely limited secondhand aerosol during actual use, effectively reducing exposure to nicotine and toxicants. This contributes to cleaner air and upholds the public’s right to a healthy and shared environment.

Internal lab testing followed ISO 20768, CORESTA TR 84, and Health Canada T-115 protocols.

3. Stable Performance Over Time

Laboratory-based simulated aging tests demonstrated that ZeroCloud™ maintained exceptional stability across key physical and chemical properties, including pH, viscosity, nicotine content, and flavor integrity, with virtually no measurable degradation over time.

4. Full Flavor and Satisfaction

Compared to traditional e-liquids, ZeroCloud™ maintains a comparable flavor profile, with no noticeable decline in user satisfaction for most regular vapers. In multiple blind tests conducted across diverse control groups, including different devices, flavor profiles, and user groups, ZeroCloud™ showed minimal difference in flavor intensity and was virtually indistinguishable to non-expert users.

Comparative testing against other smoke-free vapes showed that ZeroCloud™ consistently outperformed in flavor delivery, throat hit, and overall nicotine satisfaction.

Where ZeroCloud™ Fits Best?

As global demand shifts toward cleaner and more discreet nicotine delivery systems, ZeroCloud™ offers a timely and versatile solution. It’s invisible and has a near-zero secondhand impact, unlocking new use cases across consumer segments and device formats.

1. Where Smoking Isn’t Welcome

In regions where smoking behavior is highly sensitive, tobacco companies often struggle to expand their footprint. In many of these markets, even if smoking is legal, public bias and cultural pressure make growth difficult. In some more restrictive countries, female smokers are rarely seen. Furthermore, in places where social norms emphasize respect for personal space and boundaries, young adult consumers tend to prefer more discreet methods of nicotine consumption.

ZeroCloud™ provides a more suitable solution, helps you overcome these limitations, and expand more effectively in markets where smokers encounter resistance.

2. Ideal for Indoor Use

In the extreme heat of the season, people often stay indoors to escape the heat. However, even in indoor areas without explicit smoking restrictions, minimal smoke emissions can trigger smoke detectors or cause discomfort to others.

ZeroCloud™ produces virtually no secondhand smoke and releases no detectable odor or harmful substances, so users don’t need to worry about triggering smoke alarms. This makes it an ideal solution for use in indoor environments.

ZeroCloud™ products are intended for use only in locations where e-cigarettes are permitted by local law.

3. Building a Clean and Understated Brand Identity

ZeroCloud™ delivers invisible vapor with virtually no secondhand presence. It creates a discreet profile that aligns with low-impact brand positioning. This makes it particularly suitable for specialized markets such as Australia, where vaping products are classified as therapeutic goods, distributed exclusively through pharmacy channels, and expected to uphold a clean and restrained brand image.

ZeroCloud™ products may contain nicotine and are not associated with any health or medical benefits.

4. Wearables and Ultra-Portable Formats

ZeroCloud™ shares the same core attributes with ultra-portable and wearable devices, such as card-style formats, wristband vapes, and smart textile-integrated models. By minimizing visible vapor, it enables these discreet form factors to fully realize their design and concealment potential.
