Step

What Happens

Ingredient Sourcing

Only the best ingredients are used—pharmaceutical-grade propylene glycol (PG), vegetable glycerin (VG), and pure nicotine to keep it safe and high quality.

Nicotine Extraction and Purity

Nicotine is cleaned and purified to make sure it’s free from anything harmful, so your vaping is smooth and safe.

Weighing and Measuring

Every ingredient is carefully measured to make sure the vape juice is just right and consistent every time.

Mixing Techniques

PG and VG are different thicknesses, so they’re mixed carefully to get a smooth and even blend.

Quality Control Testing

The juice is tested in a clean lab to check nicotine strength, and to make sure there’s nothing harmful like chemicals or contaminants.

Steeping/Ageing

The juice is left to rest so the flavours mix well and taste better.

Bottling and Packaging

The vape juice is put into bottles with child-proof caps and labelled clearly, following safety rules and regulations.

Batch Testing and Traceability

Each batch is tested and tracked to keep quality high and make sure any problems can be quickly fixed.

This careful process means every bottle of vape juice you use is safe, tasty, and reliable. Looking for premium vape juice you can trust? Check out our top-quality e-liquid range today! It includes Banana Ice, Berry Lemonade, Blue Fusion, and more.

Safety, Toxicology, and Regulatory Standards:

When it comes to vape juice, safety is the top priority. Manufacturers carefully study the chemical safety and toxicology of every ingredient to make sure they’re safe for inhalation. Strict rules and regulations are in place to protect consumers and keep the industry trustworthy. Here are the key areas that ensure vape juice meets the highest standards:

  • Chemical Safety and Toxicology: All ingredients in vape juice are tested to confirm they don’t contain harmful substances and are safe when heated and inhaled.
  • Regulatory Frameworks: Laws such as the Tobacco Products Directive (TPD) and the Tobacco and Related Products Regulations (TRPR) establish strict guidelines for the manufacture, packaging, and sale of vape products.
  • Good Manufacturing Practices (GMP) and ISO Certifications: Many manufacturers follow these international standards to keep production clean, safe, and consistent.
  • Independent Lab Testing and Certification: Third-party labs regularly test vape juice to verify nicotine levels, purity, and that no dangerous contaminants are present.
  • Ethical Marketing and Accurate Labelling: Honest labelling and responsible marketing practices help consumers make informed choices and prevent misleading claims.

By following these safety and regulatory standards, the vape industry works hard to provide products that you can trust.

Impact of VG/PG Ratios on Vape Juice and Device Compatibility:

The ratio of vegetable glycerin (VG) to propylene glycol (PG) in vape juice plays a big role in how it performs. Higher VG content creates thicker vapour clouds and a smoother throat hit, while higher PG gives stronger flavour and a sharper throat hit. Finding the right mixing ratios helps balance vapour production, flavour, and throat sensation to suit your preferences.

From a manufacturing point of view, different VG/PG ratios require careful handling because VG is much thicker than PG. Producers must adjust mixing methods to keep the vape juice consistency smooth and ensure even flavour throughout the batch. These technical details help maintain quality no matter the chosen ratio.

When it comes to device compatibility, high VG juices (like 70% VG or more) work best with sub-ohm tanks or advanced vaping devices that can handle thicker liquids and produce big clouds. Juices with higher PG, such as 50/50 blends, are perfect for Starter Kits, Pod Kits, Advanced Kits, MTL Kits, Sub-Ohm Kits, offering strong flavour and throat hit without clogging the device. Customising your e-liquid’s VG/PG ratio allows you to match it perfectly with your vaping device for the best experience.
