E-Liquid Recipes: A Safety-First Guide to DIY Vape Juice in the UAE

|—|—|
| PG | 10–50% | Flavour carrier, throat hit, viscosity |
| VG | 40–80% | Vapour production, smoothness, sweetness |
| Flavour Concentrates | 5–20% | Taste and aroma |
| Nicotine (in PG/VG base) | Variable | Nicotine delivery |

A simple beginner recipe might look like this:

• 70% VG — for dense clouds and a smooth draw
• 18% PG — carries the flavour and adjusts viscosity
• 10% Strawberry Concentrate — the primary flavour
• 2% Sweetener (optional) — rounds out the taste
• Nicotine shot — added to reach the desired strength

The total must always equal 100%. Once you understand this framework, you can adapt any recipe to suit your device, nicotine preference, and flavour intensity.

Equipment Needed for DIY E-Liquid Mixing

Before attempting any e-liquid recipe, gather the following tools:

• Syringes or graduated pipettes (1 mL and 10 mL) — for precise measurement of each ingredient
• Empty e-liquid bottles (30 mL or 60 mL, PET or glass) — for mixing and storing
• Nitrile gloves — to protect your skin from concentrated nicotine
• A digital scale (accurate to 0.01g) — preferred by advanced mixers for weight-based accuracy
• Labels and a notebook — to record recipes and track steeping times

Accuracy is the single most important factor in DIY mixing. Eyeballing measurements leads to inconsistent flavour and, more critically, incorrect nicotine strength. A 1 mL syringe costs very little but makes the difference between a balanced recipe and an unvapable mess.

How to Calculate Nicotine Strength in Your Recipe

Nicotine is the ingredient that demands the most careful calculation. If you are mixing with a nicotine base (for example, 36 mg/mL in PG), you need to calculate exactly how much to add to reach your target strength.

The formula is straightforward:

(Target Strength × Total Volume) ÷ Nicotine Base Strength = Amount of Nicotine Base Needed

For example, to make 30 mL of e-liquid at 6 mg/mL using a 36 mg/mL nicotine base:

(6 × 30) ÷ 36 = 5 mL of nicotine base

That 5 mL displaces part of your PG or VG, so the remaining 25 mL is split between PG, VG, and flavour concentrates.

UAE Nicotine Regulations You Should Know

UAE regulations enforced through ESMA (Emirates Authority for Standardization and Metrology, now under MoIAT — Ministry of Industry and Advanced Technology) set important boundaries for e-liquid products:

• Maximum nicotine concentration: 20 mg/mL (2%) for freebase nicotine e-liquids sold through licensed retailers.
• All nicotine-containing e-liquids must pass ECAS (Emirates Conformity Assessment System) certification.
• Products must carry proper labelling including nicotine content, ingredient lists, and health warnings in Arabic and English.

These regulations apply to commercially sold products. For personal mixing, vapers should be aware that exceeding standard nicotine concentration limits increases health risks and may fall outside the scope of what is considered safe personal use.

Safety-First Mixing Practices

DIY e-liquid mixing involves handling chemicals that are safe when properly diluted but potentially harmful in concentrated form. Follow these safety rules every time you mix:

Handle Nicotine with Care

Concentrated nicotine is toxic. Skin contact with high-strength nicotine base can cause nausea, dizziness, and elevated heart rate. Always wear nitrile gloves, work in a well-ventilated area, and never touch your face or eyes while handling nicotine. If nicotine base spills on your skin, wash the area immediately with soap and water.

Keep Ingredients Away from Children and Pets

Nicotine is especially dangerous to children and animals. Store all nicotine-containing ingredients in childproof containers, kept in a locked cabinet well out of reach. Never leave mixing equipment or half-finished bottles unattended.

Use Food-Grade Ingredients Only

Only use PG, VG, and flavour concentrates that are specifically manufactured for vaping or food use. Industrial-grade propylene glycol or flavour compounds not intended for inhalation may contain impurities that are harmful when vaporised.

Label Everything

Every bottle should carry the flavour name, nicotine strength, PG/VG ratio, and the date it was mixed. Unlabelled bottles lead to confusion and accidental use of the wrong strength.

Step-by-Step: Mixing Your First E-Liquid Recipe

Here is a straightforward process for a 30 mL batch with a strawberry-menthol flavour at 6 mg/mL nicotine (using 36 mg/mL PG-based nicotine base):

Step 1: Prepare Your Recipe

Step 2: Measure Each Ingredient

Using a clean syringe for each ingredient, draw the exact amount and transfer it into your empty bottle. Start with the largest volume (VG) and work down to the smallest (flavour concentrates). This minimises cross-contamination between syringes.

Step 3: Cap and Shake

Seal the bottle tightly and shake vigorously for 30–60 seconds. The liquid will appear cloudy at first — this is normal, as the VG and PG are blending at the molecular level.

Step 4: Steep

Steeping is the process of letting flavour molecules fully bond with the base liquid over time. Some fruit flavours taste great after 24 hours, while dessert and tobacco flavours may need 1–2 weeks. Store your bottle in a cool, dark place (important in the UAE climate — avoid leaving e-liquid in a car or near a window). Shake the bottle once daily during steeping.

Step 5: Test and Adjust

After steeping, load the e-liquid into your device and take a few puffs. If the flavour is too weak, add 1–2% more concentrate in your next batch. If it is too strong, dilute with additional PG/VG base. Keep notes so you can refine the recipe over time.

Common PG/VG Recipe Ratios and What They Produce

Different recipes call for different PG/VG balances. Here is a practical reference:

Most pre-mixed e-liquids available in the UAE market use ratios between 40/60 and 50/50 to balance flavour and vapour across a range of devices. For example, the NASTY Nasty Juice 20mg/ml-30ml E-Liquid available on uaevape.store comes pre-mixed at a nicotine strength compliant with ESMA standards, offering a ready-to-use option for vapers who prefer not to mix from scratch.

Flavour Concentrate Categories for Recipe Building

When developing your own e-liquid recipes, understanding flavour concentrate categories helps you build balanced blends:

Single Fruit Concentrates

Strawberry, watermelon, mango, and blueberry are the most common starting points. Single-fruit concentrates are versatile — they work as standalone flavours or as building blocks for complex blends.

Cream and Dessert Notes

Vanilla custard, cheesecake, and graham cracker add richness and depth. These concentrates typically need longer steeping times (1–2 weeks) but reward patience with smooth, layered flavour.

Cooling Agents

Menthol, koolada, and ws-23 are not flavours themselves but cooling additives. A small amount (0.5–2%) transforms any fruit recipe into a refreshing “ice” variant — a style extremely popular among UAE vapers in the summer heat.

Tobacco Blends

Tobacco concentrates range from bright, cigarette-style profiles to dark, pipe-tobacco notes. These are useful for smokers transitioning to vaping who want a familiar base flavour, though they require the longest steeping times.

Steeping and Storage in the UAE Climate

The UAE’s high ambient temperatures accelerate certain chemical reactions in e-liquids — both good and bad. Nicotine oxidises faster in heat, causing liquids to darken more quickly than they would in cooler climates. While darkening alone does not mean the liquid has gone bad, it signals that the steeping process is progressing.

Practical storage tips for UAE vapers:

• Store mixed e-liquid in a cool, dark cabinet — not in a car, near a window, or next to kitchen appliances that generate heat
• If you mix in larger batches, consider refrigerating spare bottles between 2–8°C. Allow refrigerated liquid to return to room temperature before vaping to avoid condensation inside the bottle
• Keep bottles tightly sealed to minimise oxygen exposure, which accelerates nicotine degradation
• Label bottles with the mix date and use within 12 months for optimal flavour quality

DIY Mixing vs. Ready-Made E-Liquids: Which Is Right for You?

DIY mixing is not for everyone. Here is an honest comparison:

For many UAE vapers — especially those new to vaping — ready-made e-liquids offer a simpler, safer starting point. You can explore the E-LIQUIDS category on uaevape.store to find pre-mixed options that comply with UAE standards. DIY mixing becomes worthwhile once you have specific flavour preferences that commercial options cannot satisfy, or when you want to experiment with custom PG/VG ratios for a particular device.

Common DIY E-Liquid Mistakes to Avoid

1. Over-Flavouring

More concentrate does not mean better flavour. Most recipes perform best at 8–15% total flavouring. Exceeding 20% can produce a harsh, chemical taste and may damage coils faster.

2. Ignoring Nicotine Base Strength

Using the wrong nicotine base concentration in your calculations leads to a final product that is either far too strong or far too weak. Always double-check the strength printed on your nicotine base bottle before calculating.

3. Not Steeping Long Enough

Impatience is the number one reason new mixers give up on a promising recipe. Dessert and tobacco flavours in particular need 7–14 days to reach their full potential. If a recipe tastes flat or chemical-heavy after 24 hours, it may simply need more time.

4. Using Contaminated Equipment

Reusing syringes between different flavour concentrates without cleaning them leads to flavour cross-contamination. Use separate syringes or wash thoroughly with warm water and let dry completely between uses.

5. Mixing Without a Recipe

Improvising without recording percentages makes it impossible to reproduce a successful batch — or avoid repeating a failed one. Always write down every measurement.
