Nicotine salts have rapidly become the preferred choice in the vaping industry, favoured for their smoother vape and faster nicotine absorption. Found in almost all disposables and as the most popular e-liquid type in our vape shop, their widespread adoption highlights their effectiveness.
However, personal experiences can vary significantly. For example, I’ve found that nicotine salts with salicylic acid cause me to sneeze and cough, unlike those based on benzoic acid. This article explores why some nicotine salts may feel harsher and how individual sensitivities can affect your vaping experience with various different nic salts.
Understanding Nicotine Salts
What are Nicotine Salts?
Nicotine salts are a form of nicotine found in leaf tobacco. They are utilised in vaping products to more closely mimic the natural nicotine absorption process than traditional freebase nicotine. This is achieved by adding acids such as salicylic acid or benzoic acid, which bind to the nicotine, allowing for a smoother throat hit and quicker absorption into the bloodstream.
Why are Nicotine Salts Popular?
The popularity of nicotine salts in vaping arises from their ability to provide a satisfying nicotine hit without the harshness associated with higher nicotine levels in freebase solutions. This makes them particularly appealing to both new and seasoned vapers who are looking for an effective alternative to smoking.
Salicylic Acid vs. Benzoic Acid in Nicotine Salts
Salicylic Acid in Nicotine Salts
Salicylic acid is considered by some manufacturers as a premium additive in nicotine salts. It is often touted for its supposed superior stabilisation properties. However, it is also associated with a harsher throat hit, which can be a drawback for users looking for a smooth vaping experience.
Why Manufacturers Choose Salicylic Acid: Salicylic acid is selected by some manufacturers for its unique properties that are believed to enhance the performance and stability of nicotine salts. This organic acid is touted for its supposed superior stabilisation properties, which include:
- Enhanced Stability: Salicylic acid is thought to stabilize nicotine in its salt form more effectively than other acids. This enhanced stability can prolong the shelf life of the e-liquid and maintain the integrity of the nicotine, providing a consistent experience over time.
- Unique Sensory Profile: Manufacturers may also choose salicylic acid due to its impact on the sensory aspects of the vaping experience. It can alter the flavour profile in subtle ways that might be preferred in certain formulations, potentially enhancing the overall taste and sensation.
- Marketing Appeal: The use of salicylic acid can be a selling point, particularly in markets where consumers are looking for premium or distinctively different products. By branding their nicotine salts as containing a ‘premium’ ingredient like salicylic acid, manufacturers tap into consumer desires for exclusive and high-quality products.
Drawbacks of Salicylic Acid:
Despite these perceived benefits, salicylic acid comes with its drawbacks, primarily related to user experience:
Harsher Throat Hit: While salicylic acid can offer enhanced stability and potentially richer flavours, it is also associated with a harsher throat hit. This can be uncomfortable for users who prefer a smoother vaping experience. The harshness can detract from the enjoyment and may lead to irritation of the throat, which is less ideal for users transitioning from traditional cigarettes or those using vaping as a nicotine replacement therapy.
Potential Sensitivities: As noted from personal experiences and consumer feedback, salicylic acid may trigger more pronounced physical reactions such as sneezing and coughing. These reactions suggest that some users could be more sensitive to salicylic acid compared to other additives, which might limit its suitability for a broader audience.
Benzoic Acid in Nicotine Salts
On the other hand, benzoic acid is widely used because it tends to provide a more balanced throat hit and enhances nicotine delivery, making it less harsh than salicylic acid. Brands like Bar Juice 5000 utilise benzoic acid to create cost-effective and user-friendly vaping experiences. Its widespread use and acceptance in the market reflect its effectiveness in creating a pleasant vaping experience.
Why Manufacturers Choose Benzoic Acid: Benzoic acid is a popular choice among manufacturers for several compelling reasons. It offers a balance of effective nicotine delivery and user comfort, making it a staple in many popular vaping products:
- Enhanced Nicotine Delivery: Benzoic acid is known for its ability to lower the pH level of nicotine solutions, which results in increased bioavailability. This means that nicotine is absorbed more efficiently by the body, providing a satisfying hit without the need for extremely high nicotine concentrations.
- Smoother Throat Hit: One of the key advantages of using benzoic acid in nicotine salts is its ability to provide a smoother throat hit compared to other acids like salicylic acid. This makes it ideal for users who are looking for a pleasant vaping experience without the harshness that can sometimes accompany higher nicotine levels.
- Flavour Preservation: Benzoic acid is less likely to alter the flavour profiles of e-liquids. This characteristic is crucial for maintaining the integrity of the intended flavours, allowing for a more enjoyable and consistent vaping experience across different products.
- Market Appeal: The use of benzoic acid can enhance the market appeal of nicotine salts. Products formulated with benzoic acid are often marketed as smoother and more user-friendly, attracting a broader range of consumers, from beginners to seasoned vapers.
Drawbacks of Benzoic Acid:
While benzoic acid is generally well-received, it is not without its challenges:
Chemical Sensitivity: Although less harsh than salicylic acid, benzoic acid can still cause sensitivity in some users. Symptoms such as mild throat irritation or a slight cough can occur, particularly with prolonged use or high concentrations.
Regulatory Scrutiny: As with any additive, the inclusion of benzoic acid in vaping products can draw regulatory scrutiny. The EU’s Tobacco Products Directive (TPD) imposes strict limits on the concentration of benzoic acid in nicotine salt e-liquids, capping it at 1.0 mg/ml.
These limits are designed to minimize health risks while allowing for the beneficial effects of smoother nicotine delivery. Similar regulations are observed in other regions, with local variations based on health risk assessments (Public Health) (European Medicines Agency (EMA)).
Currently, there are no specific regulations or standardized concentration limits, such as the 1.0 mg/ml cap that exists for benzoic acid, specifically targeting the use of salicylic acid in nicotine salts for vaping. This difference likely stems from the fact that benzoic acid is far more commonly used in nicotine salt formulations, making it the focus of regulatory frameworks like the EU’s Tobacco Products Directive (TPD).
Salicylic acid is regulated under general chemical safety and consumer product laws, which apply broadly to substances used in consumer goods, including vaping products. These regulations require that any concentration of salicylic acid used in e-liquids must be safe for inhalation and must be clearly labelled on the product. However, specific concentration limits for salicylic acid in vaping products, akin to those for benzoic acid, are not widely established or enforced at this time.
Manufacturers using salicylic acid in their nicotine salts would need to ensure that their products comply with overarching safety standards but without the specific concentration caps that are in place for benzoic acid. This might be due to its less frequent use and possibly a different risk profile than benzoic acid.
For precise information and updates, manufacturers and stakeholders typically consult the latest regulatory guidelines from bodies such as the MHRA in the United Kingdom and the EMA in Europe, which outline permissible ingredients and their acceptable concentrations in consumer products, including vaping devices and e-liquids.

How Do You Know What Acid a Specific Nicotine Salt Vape Juice Is Made With?
Determining the specific acid used in a nicotine salt vape juice can be challenging, as manufacturers do not always provide this information on the product label. This lack of transparency can be frustrating for vapers who have a preference for either benzoic acid or salicylic acid due to differences in throat hit, smoothness, or personal sensitivities.
Challenges in Identifying the Acid Used:
- Incomplete Labeling: Unfortunately, many vape juice manufacturers do not specify the type of acid used to create the nicotine salts on their product labels. This omission can make it difficult for consumers who prefer a particular type of nicotine salt to make informed purchasing decisions. The absence of this information is likely because the specific acid type is not widely seen as a major selling point by many brands.
- Lack of Industry Standardization: There is no industry-wide standard requiring manufacturers to disclose the acid type used in nicotine salts. This means that even if some brands do provide this information, it is not consistently available across all products, further complicating the process for consumers.
Future Plans for Improved Transparency:
Recognizing the importance of this information, we are actively working towards including the type of acid used in all our nicotine salts in the future. This initiative aims to help customers find exactly what they want based on their preferences and needs.
