E-liquids, also known as vape juice, are the essential component of the vaping experience. Whether you’re new to vaping or a seasoned pro, understanding the different types of e-liquids, their benefits, and key specifications will help you find the perfect juice for your device. Let’s explore the different types of e-liquids, the benefits of each, and provide information on TPD regulations, nicotine strengths, VG/PG ratios, bottle sizes, shortfills, and longfills.

Types of Nicotine based E-Liquids

E-liquids come in a variety of types, each offering distinct flavours and experiences. The most common types of e-liquids are:

1. Freebase Nicotine E-Liquids
2. Nicotine Salt E-Liquids

Let’s dive into each type.

1. Freebase Nicotine E-Liquids

What Are Freebase Nicotine E-Liquids? Freebase nicotine is the most commonly used form of nicotine in e-liquids. It is the purest form of nicotine and is typically extracted from tobacco leaves. Freebase nicotine e-liquids are known for providing a stronger throat hit, making them a popular choice among long-time smokers.

Benefits of Freebase Nicotine E-Liquids:

• Strong Throat Hit: Provides a noticeable throat hit, similar to the sensation of smoking a traditional cigarette.
• Wide Range of Flavours: Freebase nicotine e-liquids are available in a vast array of flavours, from fruits and desserts to menthols and tobaccos.
• Customizable Nicotine Strength: You can find freebase nicotine e-liquids in a variety of nicotine strengths, allowing you to adjust your vaping experience.

2. Nicotine Salt E-Liquids

What Are Nicotine Salt E-Liquids? Nicotine salt (or salt nicotine) is a newer form of nicotine used in e-liquids. It is naturally found in tobacco leaves and is processed to create a smoother vaping experience. Nicotine salt e-liquids provide a faster nicotine absorption rate, which mimics the sensation of smoking a cigarette more closely than freebase nicotine.

Benefits of Nicotine Salt E-Liquids:

• Smoother Throat Hit: Nicotine salts provide a smoother throat hit, even at higher nicotine strengths, which is ideal for newer vapers or those looking to avoid harshness.
• Faster Nicotine Absorption: Nicotine salt e-liquids are absorbed faster, delivering quicker satisfaction with less vaping.
• Ideal for Low-Wattage Devices: Nicotine salts work well with pod systems and other low-wattage devices, making them perfect for portable and discreet vaping.

TPD Compliance for E-Liquids

The Tobacco Products Directive (TPD) is a European regulation designed to ensure that vaping products meet specific safety and quality standards. Key TPD guidelines include:

• Max 10ml Bottles for Nicotine E-Liquids: E-liquids containing nicotine must be sold in bottles of no more than 10ml to comply with TPD regulations.
• Childproof Caps: All nicotine-containing e-liquids must be sold with childproof caps to prevent accidental ingestion.
• Nicotine Strength Limits: E-liquids containing nicotine must not exceed 20mg/ml.

These regulations help ensure that e-liquids are safe for consumers while keeping vaping within legal boundaries.

Nicotine Strengths in E-Liquids

Nicotine strength is one of the most important factors to consider when choosing an e-liquid. The right nicotine strength will depend on your vaping style, your previous smoking habits, and personal preference. Here’s a breakdown of common nicotine strengths:

• 0mg Nicotine: No nicotine, ideal for those who want to enjoy the flavour of e-liquids without any nicotine content.
• 3mg Nicotine: A mild nicotine strength, perfect for those who don’t need a strong hit but still want some nicotine satisfaction.
• 6mg Nicotine: Slightly stronger, this strength is ideal for light smokers or those transitioning from cigarettes.
• 12mg Nicotine: Suitable for moderate smokers or those who prefer a more noticeable throat hit.
• 18mg and 20mg Nicotine: High nicotine strengths for heavy smokers or those who require a stronger nicotine hit to satisfy cravings.

Nicotine strengths are available in both freebase and nicotine salt e-liquids.

VG/PG Ratios in E-Liquids

The VG (Vegetable Glycerin) and PG (Propylene Glycol) ratios in e-liquids determine the consistency, throat hit, and vapour production. Here's what each ratio means:

• VG (Vegetable Glycerin): VG is a thicker liquid that produces larger vapour clouds. It’s smoother on the throat, making it ideal for sub-ohm vaping and cloud chasers.
• PG (Propylene Glycol): PG provides a stronger throat hit and is often used to mimic the sensation of smoking a traditional cigarette. It carries flavour more effectively but produces less vapour.

Common VG/PG Ratios:

• 70/30 VG/PG: A good balance for sub-ohm vaping, producing thick clouds and a smooth throat hit.
• 50/50 VG/PG: Perfect for pod systems and low-wattage devices, providing a balanced throat hit and good flavour delivery.
• 80/20 VG/PG: Used primarily in high-wattage mods for cloud chasing, providing huge vapour production with a lighter throat hit.

Shortfills & Longfills

E-liquids come in various bottle sizes, but two of the most popular are shortfills and longfills.

Shortfill E-Liquids:
Shortfill e-liquids are bottles that are filled to 50ml or 80ml but contain no nicotine, leaving room for a nicotine shot (or booster) to be added. They are ideal for those who prefer larger bottles and want to customize their nicotine strength.

• 80ml of flavoured liquid in a 100ml bottle with space for 2x 10ml nicotine shots.
• 50ml of flavoured liquid in a 60ml bottle with space for 1x 10ml nicotine shot.

Longfill E-Liquids:
Longfill e-liquids typically come in 60ml bottles with concentrated flavours. They allow room for adding a nicotine shots & base mix, making it easy to achieve your desired nicotine strength without compromising on flavour.

Benefits of Shortfills and Longfills:

• Customizable Nicotine Strength: Both shortfills and longfills allow you to tailor your nicotine strength by adding nicotine shots.
• Cost-Effective: These larger bottles are often more economical than smaller, pre-filled bottles.
• Variety of Flavours: Both types offer a wide range of flavour options, allowing for greater variety in your vaping experience.

Conclusion

Choosing the right e-liquid is a critical aspect of the vaping experience. From freebase nicotine e-liquids to nicotine salts e-liquids, each type offers unique benefits suited to different preferences. With the right nicotine strength, VG/PG ratio, and bottle size, you can customise your vaping experience to match your needs. Understanding TPD compliance ensures that you're purchasing safe, legal products, while the flexibility of shortfills and longfills allows for a personalized vape juice creation. Whether you’re a beginner or an experienced vaper, the world of e-liquids has something for everyone.
