What are the ingredients of LIQUA e-liquid?

By following the link you could find the summary of ingredients that are present in Liqua e-liquids currently sold in European Union with full compliance to the requirements of European Tobacco Products Directive 2014/40/EU (TPD)

General List of Ingredients and Maximum Concentration Limits

Limit of detection is 0.0001%. The actual content and concentration of each substance depends on the type of liquid, local country legislation and chemical legislation, such as REACH, and each liquid goes through the TPD notification process before being introduced for sales.

How and in which environment do you handle with ingredients?

Our cleanroom environment is GMP food industry level and ISO Level 7. Certified to ISO9001 standards. We wash all of our bottles, nozzles, and caps in 5 stages of ultrasound cleaning and ultrapure compressed air drying.

Different materials require different storage solutions. Most of them are contained in industrial refrigeration units with specific, ideal temperatures for each ingredient. We use a Zero Cross Contamination protocol for all materials to ensure 100% quality during the entire manufacturing process. That protocol ensures that different products never contact the same surface, tubings or tools. Dispensing is done through gravimetric measurements with 0.1% USP precision levels. Mixing results are controlled by multi-sampling from batches to ensure an even spread of material across the batch.

What nicotine level should I choose?

For cigarettes per day up to 10pcs, we recommend 6mg.
For 20 pcs/day, 12mg would be a good choice.
For 30 pcs/day, it will be 18mg.

What is PG and VG?

VG is Vegetable Glycerol, a safe food additive used in most of the food and also naturally exists in most of the organic food. It is sweet in taste and helps to produce more vapor.

PG is Propylene Glycol, a similar component to VG, it's used as a safe food additive and while less sweet, it makes more balanced taste.

VG is derived by extraction from plants as raw material. PG can be derived from VG, but normally as most of the organic chemicals, it's derived initially from fossil fuel (oil/gas).

What does "4S" mean?

LIQUA 4S stands for “For Smokers”. It is an innovation in vaping for smokers, the nicotine salts and matching device, that
- Delivers Full Nicotine Feel
- Works as Device and Liquid created for each other
LIQUA 4S is not just another device and e-liquid. This is the beginning of a completely new page in the vaping industry efforts of reaching hearts of Smokers.

What is the difference between LIQUA 4S Vinci and Voopoo Vinci R?

The device and atomizer for the LIQUA 4S Vinci device are specially made for the 4S solution. Electronic functions have been simplified to avoid the risk of potential wrong usage. On top of this - it’s a unique distinctive color combination of the product on the market.

Can I use other Voopoo atomizers? What about using different or other brands’ e-liquid?

LIQUA 4S Vinci includes specially designed atomizers that are tailored to work together with LIQUA 4S e-liquid. Although you can use another atomizer from the Vinci line - performance would be inferior to the task: leakage, wrong nicotine delivery, taste issues.

LIQUA 4S e-liquid is a unique product for the device. It has specially selected nicotine, the unique recipe of nicotine-salt, flavors matched with device performance, the safe formulation for the materials of the device with prolonged atomizer usage. While you technically can use another e-liquid - we strongly suggest against it.

How long can I use the LIQUA 4S Vinci replacement atomizer?

It is recommended to change to a new atomizer after every 2 bottles or at least when you feel that atomizer gives an off-smell. Life of an atomizer is seriously impacted by the amount of dust in the environment as well as the duration of puff and speed of inhalation.

With LIQUA 4S e-Liquid we did our best to ensure the balance between potential leakage and atomizer life as well as ensured full compatibility of flavor recipe with device materials.

How to use the LIQUA 4S Vinci device for the first time?

Install the atomizer. Take it out of the package and insert it from the bottom of the pod. Fill e-liquid into the pod. Pull out the silica gel plug according to the instructions, refill e-liquid through filling holes. Install the plug back making sure it’s sealed. It is recommended to keep it two thirds full. Install the pod into the battery. Ensure that it sits right. Wait for 5 minutes before the use of a new atomizer. If atomizer was used before - you don’t need to wait. Turn on the device. Make 5 fast consecutive clicks on the button until LED light will turn on. Make a puff. Press the button on the battery during the puff.

How long should I charge? How do I know if the battery is fully charged?

We suggest charging if the red LED signal is on(low battery) when pressing the button.

It takes around 1.5 hrs from completely out of battery to fully charged. Green LED is on and in a steady state when the battery is fully charged.

What to do if I break my pod?

You can purchase a replacement pod for Voopoo Vinci in the stores where LIQUA 4S is sold. It doesn’t have to be branded as LIQUA as long as it’s the Vinci or Vinci R replacement pod.

What is nicotine salt?

Nicotine Salt = Freebase Nicotine + Acid

In chemical terms, a salt results when an acid reacts with a base.

Freebase nicotine was invented by tobacco companies in the 1960’s. Freebase means that the nicotine is in the purest form compared to the other nicotine derivatives. This form of nicotine is used in cigarettes and many common nicotine replacement therapies (NRT’s). The form of nicotine ordinarily used in standard e-liquid is freebase nicotine.

What are the main ingredients of LIQUA 4S nicotine salt e-liquid?

Glycerol, Propylene Glycol, Nicotine Salt, Flavorings

LIQUA 4S salt is not just another nicotine salt - it's a unique recipe that we were gradually improving over 5 years.

What are the differences between Nicotine salt e-liquid and Freebase e-liquid?

The Harshness
Freebase Nicotine has a higher pH level which in turn affects the alkalinity. It causes a harsher throat-hit. Nicotine salt has lower alkalinity due to the acid which gives you smoother vaping experience.
The nicotine absorption rate into the blood

Nicotine Salt e-liquid has a faster absorption rate. The pH level is more suitable for absorption.

LIQUA 4S offers you the same nicotine delivery as cigarettes in combination with 4S devices and 4S e-liquid.

What are the benefits of nicotine salt e-liquid VS freebase nicotine e-liquid?

Smoother Throat Hit
Because of the acid in nicotine salt, it has a lower pH level and is therefore much more smooth and enjoyable. It is possible to choose higher nicotine strength.
Faster Absorption Rate
Nicotine salt e-liquid will enter the bloodstream faster than traditional e-liquid. It provides a blood absorption rate closer to an actual cigarette. It is a better solution in the transition period from cigarette to vaping if you try to quit cigarettes.
More Economical
With higher nicotine levels and better absorption, you will not need to consume as much e-liquid.

What devices are recommended to use with LIQUA 4S nicotine salt e-liquid?

LIQUA 4S nicotine salt e-liquid is ideal for the mid-power devices around 30W.

LIQUA 4S Vinci device, tailored to work together with LIQUA 4S e-liquid is coming soon.

What are those differences between LIQUA 4S nicotine salt and other salt in the market?

LIQUA 4S salt is not just another nicotine salt - it's a unique recipe that we were gradually improving over 5 years.

Safety First

We studied more than 30 nicotine salts to choose the best recipe.

Most salts on the market have dangerous STOT L1 for Eyes Damage. Others are highly unstable and irritate the digestive tract.

We are confident that our choice is by far the safest on the market. We have tested it internally and on the market for more than 5 years. Ritchy pioneers best practices for development, manufacturing, and quality check.

4S Nicotine Salt is the Proper Cigarette Substitute

It's impossible to make proper delivery of nicotine without nicotine salt. Salt needs to have properly balanced pH to have correct absorption.

The atomizer needs to be tuned for a proper peak of droplet size. Smokers need adjusted pairing of e-liquid and device power. The throat-hit vs nicotine delivery is the second most important factor. As usual, we spent a lot of time to ensure 2 years of product shelf-life.

We also achieved the lowest impact on taste performance in our nicotine salt.

Does LIQUA 4S nicotine salt e-liquid contain benzoic acid?

Benzoic acid is a common additive to food, drinks, and other products. But the high concentration of benzoic acid can irritate the eyes, skin, lungs, and digestive tract.

LIQUA is guaranteed to be free of benzoic acid. We prioritize users' safety, research and develop our own acid for the nicotine salt e-liquid.

How can I check the authenticity of LIQUA?

Every bottle of LIQUA has a united QR code located on package/bottle. Scan the code with any suitable application on your smartphone and you'll automatically verify the authenticity. Also you may enter authenticity code manually.

Do you use natural extracts?

It is popular in the vaping industry to claim ‘made with natural extracts’. The fact is that many natural extracts, when inhaled, contain impurities and harmful (though naturally occurring) chemicals such as diacetyl or acetoin. These levels can be anywhere from 100 to 1000 times the limits we set for ourselves. For this reason, we do not specifically favor natural extracts unless they meet our purity requirements.

For us, this often requires a more complicated compounding formulation from basic components to avoid unwanted materials in the final product, but we believe this method is worth it.

Do you use water in LIQUA e-liquid?

We don’t routinely use water in our products. We discovered very early in our careers that the atomization process is much worse with high water content, so we try to keep water content to a minimum. Some flavors do contain a small amount of water when particular components require its solving property.

How should I store LIQUA e-liquids?

Please out of direct sunlight in a dry condition at 15 to 25°C.

Keep out of reach of children.

Do LIQUA e-liquid contain alcohol?

Some of our flavors do contain alcohol, but not enough to have any effect on the consumer. Alcohol is normally used as a solvent for some of our raw materials, so it is a necessary part of the production process. In some cases, it’s a small part of the original natural extract that doesn’t pose any risk or perceivable effect.

How do you select reliable suppliers?

We have our own very strict standards for supplier selection and a rigorous validation process to ensure potential suppliers meet these requirements. We always check the history of our suppliers and personally visit almost all of them to verify their 9001/GMP standards. We run routine tests of all of our batches of e-liquid to ensure that the quality meets our standards. All quality control is done in our own fully-equipped laboratory.

How does LIQUA ensure the quality of PG/VG?

We only use the USP standard, Kosher certified PG and VG in our e-liquids. These provide minimum odor, which can influence the overall taste. Most manufacturers are not concerned with the smell of these ingredients, but we think it’s very important as these odors interfere with the taste perception of the e-liquid.

What is the quality of nicotine in LIQUA e-liquid?

Nicotine quality is of the utmost importance to us. People often don’t realize that bad nicotine can ruin the vaping experience. We only use nicotine with 99.9% purity, which is above USP pharmaceutical standards. Further, our nicotine has been treated to additional stages of distillation, lowering residual alkaloids and odor, resulting in the highest possible quality and best possible vape.
