Cooling effect: How menthol and Koolada cool the vapor

The subtle difference: Coolness without mintFlavour

Many vapers appreciate the fresh sensation when inhaling, similar to that of menthol. However, not everyone is a fan of the characteristic minty taste.FlavourThis is where Koolada comes in: an additive developed to create a pure, cool sensation without the Flavour to alter the e-liquid. While menthol is a well-known ingredient, Koolada often works in the background to give fruity or sweet flavors a refreshing kick.

If the cold shock is too intense for you, you can... Ice-Easing the effect when vaping.

This article explains the fundamental differences between these two cooling agents. We explore how they affect the vaping experience, from the FlavourFrom personal perception to the effect in conjunction with modern hardware. This knowledge helps you to specifically find the e-liquid that perfectly matches your preferences for freshness.

What is menthol? The classic for icy freshness.

Menthol is an organic compound that occurs naturally in plants of the mint family. Due to its "Generally Recognized as Safe" (GRAS) status by FEMA (Flavor and Extract Manufacturers Association), menthol has been used safely in the food and pharmaceutical industries for decades.

In the context of e-liquids, menthol activates the cold receptors in the mouth and throat (known as TRPM8 receptors). The brain interprets this signal as cold, even though the physical temperature of the vapor remains unchanged. The crucial point with menthol, however, is that it is inextricably linked to its own distinctive aroma. FlavourThe profile is associated with a clear, often sharp mint note.

For lovers of this FlavourThat's ideal. Varieties with Terms such as "Ice", "Menthol" or "Mint" deliberately rely on this effect. A product like the ELFBAR 800 Blackberry Ice For example, it combines fruit flavor with a strong menthol finish. A potential drawback that we frequently see in user feedback is that very high concentrations of menthol can unpleasantly intensify the so-called "throat hit" (the scratchy feeling in the throat) for some users.

What is Koolada? Coolness without Flavour

Koolada is a collective term for synthetic cooling agents, primarily WS-23 (Methyl diisopropyl propionamide) as well as WS-3 and WS-5. These substances were originally developed to isolate the cooling effect of menthol without its Flavour or to take on a smell.

The mechanism of action is also based on the stimulation of TRPM8 receptors. However, in our internal sensory tests, we observed significant differences in perception:

• WS-23: Creates an immediate, intense cooling sensation in the front of the mouth and on the tongue.
• WS-3: It has a delayed effect, but its effects last longer in the back of the throat.

Koolada's biggest advantage is its FlavourNeutrality. It allows manufacturers to add a refreshing dimension to a peach or lemonade flavor without masking its original character. Because it enhances the throat hit compared to menthol Hardly affected, it is the first choice for vapers seeking a "frosty" experience without added harshness.

Menthol vs.Koolada: A direct comparison

Based on our application tests and chemical data sheets, we have summarized the most important differences for you:

The role of hardware: Mesh coils as "cooling accelerators"

The perceived cooling effect depends significantly on the e-cigarette used. Our observations from technical support show that devices with mesh coils massively increase the cooling effect.

Unlike traditional wire coils, mesh coils have a larger, grid-like surface area. This results in:

1. Higher aerosol levels: More particles of the cooling agent reach the receptors simultaneously.
2. Uniform evaporation: Prevents localized overheating, thus better preserving the subtle nuances of Koolada.

Practical tip: A liquid that is in a standard-Pod system The "mild-fresh" effect can be achieved in a mesh device like the ELFBAR The 800 V2 can cause an intense "brain freeze". If you are switching to mesh systems, we recommend starting with lower cooling levels.

DIY Guide: Safe Handling of Cooling Additives

If you want to mix or refine your own e-liquids (e.g., with the ELFA TURBO Refillable PodExtreme caution is advised. Cooling concentrates are highly effective.

Safety instructions for dosage:

• Protective equipment: Always wear gloves when handling highly concentrated WS-23 or menthol solutions. Skin contact can cause irritation.
• "Start Low, Go Slow": Start with maximum 0.5% (approx. 1 drop per 10 ml). An overdose can cause Flavour completely overwhelm the liquid and lead to an unpleasant stinging sensation in the throat.
• Storage: Store concentrates in a cool, dry place. Keep well out of reach of children and pets on.
• Do not use undiluted: Cooling agents are additives and must never be vaped or ingested undiluted.

Safety and quality: Regulatory background

Both menthol and WS-23 are considered permitted ingredients if the TPD (Tobacco Products Directive) guidelines are followed. In Germany, the Federal Institute for Risk Assessment (BfR) monitors compliance.BfR) the safety of e-cigarettes.

Important to know: While the toxicological data for the oral intake (Food/Drink) are very well documented, the research situation regarding long-term inhalation Synthetic refrigerants are still the subject of ongoing research. Reputable manufacturers such as ELFBAR Therefore, we only use ingredients that are subject to strict purity tests.You can find more details in our guide: "What is actually contained in the e-liquid of a disposable vape?"

Conclusion: The choice between menthol and koolada is a matter of personal preference. Menthol offers the full mint aroma, while koolada provides the "invisible" cooling sensation. Carefully test different concentrations to find your personal "sweet spot" for the perfect refreshment.
