E-liquid Facts & FAQs

A necessary part of electronic cigarettes is e-liquid. With that in mind, we have provided this section of our site to give users all you need to know more about e-liquid. Here at Totally Wicked we understand that e-liquid is not a household term, it is even possible that people who have used e-liquid for a long time do not know the first thing about it; we have aimed to make the information as simple as possible so that everybody who wants to learn more can do so with ease. We hope that this will help all users to make an informed decision about the e-liquid they choose to vape.

Below are some frequently asked questions that should answer all of those things commonly asked. 

Frequently Asked E-liquid Questions

Here at Totally Wicked we are delighted to answer any questions our customers have regarding the e-liquid we manufacture in the USA, UK, or import from our international partners. The Product & Technical team fields questions that have been passed on by our customer service advisors on a daily basis, and we make it a priority to provide a detailed response that our customer service team may convey back to you.

The Totally Wicked Product & Technical team has extensive scientific and engineering experience, combined with high specification analytical facilities at our UK e-liquid manufacturing site. This investment and wide-ranging experience has enabled Totally Wicked to establish comprehensive technical data sets for each e-liquid product we supply to you.

We have listed below a snapshot of frequently asked e-liquid questions that our Product & Technical team has received. The list is not intended to be comprehensive, nor is it in any particular order of frequency or importance. We hope you find it informative, and please keep the questions coming!


What is e-liquid?

E-liquid is the liquid that fuels an electronic cigarette. It consists of three parts: the nicotine solution, the flavour and the diluent. These three parts create the vapour that is exhaled to mimic the smoke that you would see if you were to smoke traditional cigarettes.

What is nicotine?

One of the stimulants and addictive substances found in cigarettes. Remember though, nicotine is not the dangerous component of cigarettes. Nicotine, when used at the current strength, is safe to vape. We strive to provide the best possible quality nicotine bases for our fluids. In our UK or USA produced fluids or our mix your own nicotine solution, we only use UK manufactured Pharmaceutical grade nicotine. Indeed, we were the first company in 2009, to offer customers UK and USA sourced and manufactured e-liquid.

What is diluent?

The diluent performs two functions. Firstly, it is added to dilute the mixture of nicotine and flavours to the desired strength and secondly, it provides the constituent that produces the vapour. The vapour is inhaled and transports both the flavour and nicotine from the e-cig to the user. All our diluents are high-quality food grade.

What is e-liquid flavouring?

Nicotine has no discernible taste. Therefore to produce the taste in e-liquid a flavour needs to be added. There is an infinite number of flavours that can be used. We believe we stock not only some of the finest tasting and highest quality e-liquid flavourings but also one of the widest and most exciting ranges available. All our flavourings have been developed and made exclusively for Totally Wicked; you will not find them anywhere else!

What strength e-liquid should I use?

This is a difficult one to answer as each vaper is different. A general rule of thumb is if you are a new starter smoking 20 a day you should start with an e-liquid strength of around the 18mg/ml (1.8%). If you start into sub-ohm vaping or variable voltage or wattage you might want to lower your nicotine strength. The best bet is to try a variety and see which suits you best. 

What flavour e-liquid should I use?

Once again, this is personal preference. Some people will always stick to tobacco flavours so they have the complete sensation of smoking, others move away from tobacco flavours straight away. They go for some of the more exotic fruit or drink flavours. Take advantage of our e-liquid tiered pricing to trial a variety of flavours whilst getting great savings.

Has it been proven that flavoured e-liquids produce toxic levels of aldehydes?

No, definitely not! One study, accompanied by a grossly irresponsible press release, made headlines in some national newspapers late in 2016. The data presented was contradictory with other peer-reviewed scientific papers on e-cigarette emissions for flavoured e-liquid.

Our own emission testing program, which has included over 100 flavour combinations, also completely contradicts this study. We suspect the data set will not be reproducible by any other research group, and no validation of the data has been forthcoming. Dr Farsalinos, the eminent e-cigarette researcher, has obtained funding to precisely recreate this study to ascertain its validity. It should also be noted that this report was based on a select few USA manufactured e-liquids, for which we have no indication on the quality systems used in their manufacture.

Do Totally Wicked e-liquids contain alcohol (ethanol)?

When we ask if a product contains alcohol we are usually referring to the type we enjoy to drink (ethanol). There are other types of chemicals that can be used as flavour ingredients that are correctly described as “alcohols” in terms of their chemistry but are not intoxicating in the same way as ethanol.

Firstly, let us deal with UK manufactured e-liquid. Ethanol is included at very low levels as a flavour enhancer (approx. 0.1 % w/w) in Red Label Black Magic, Tobacco and Tobacco Menthol but is not present in any other Red Label or Diavlo flavours at quantifiable levels. Gold Standard flavour concentrates are alcohol-free (above trace levels).

For USA manufactured e-liquid, ethanol is included at low levels as a flavour enhancer in the following Totally Wicked Patriot E-liquid products: American Red Tobacco, Blimey, Blueberry, Caramel, D-Pip, Golden Fleece, Grape, Lemonade, Lemon Melon, Lemon Rush, Mixed Berry, Raspberry Reef, Strawberry, Strawberry Dream, Strawberry Kiwi, Strawberry Menthol, Sunburst Splash, Tiger’s Blood, Urban Kool.

Totally Wicked Titan e-liquids do not contain alcohol (above trace levels).

Should I vape when suffering from Chronic Obstructive Pulmonary Disease (COPD)?

COPD is a condition that most commonly affects middle aged or older adults who smoke or who have smoked. Breathing problems tend to get worse over time and can limit normal activities. The most effective treatment for COPD is to stop smoking. The best way for you to achieve this can only be determined following consultation with your Doctor or relevant healthcare professional.

Do Totally Wicked e-liquids contain diacetyl, acetyl propionyl, or acetoin?

Our quality control system ensures all e-liquid products (USA and UK) are free from diacetyl, acetyl propionyl, and acetoin (to established limit of quantification). We make this unequivocal guarantee to our customers.

Do Totally Wicked e-liquids contain sugar?

No. The two most common types of sugar in our diets are refined and fruit sugars, known as sucrose and fructose. Sucrose is the type of granulated sugar we use to sweeten coffee or bake cakes but it is not present as a flavour enhancer in any of our e-liquids. Some confectionary type flavours contain synthetic flavour enhancers maltol and ethyl maltol, but not refined sugar. Lactose is another type of disaccharide sugar that you may be familiar with as it is present in milk. Lactose is not used as an ingredient in any of our e-liquid products.

Are Totally Wicked e-liquids suitable for diabetics?

We can assure you that our e-liquid does not contain free sugar, the type associated with high blood sugar and diabetes. Free sugars are any sugars added to food or drink or found naturally in fruit juices, honey, and syrups. If you have any further concerns then we would advise you to consult your GP and/or healthcare professional.

Are Totally Wicked e-liquids suitable for vegans?

Our vegetable glycerine is derived from rapeseed, flavours are synthetic, and propylene glycol is a synthetic product which is not derived from any animal-related ingredient. This means no animal products or by-products are used in their manufacture. Therefore we can state that our e-liquid is suitable for vegan/vegetarian customers.

Does glycerine (VG) contain alcohol or animal fats?

Our UK supplied vegetable glycerine is derived from rapeseed, hence the name vegetable glycerine. Our USA manufactured e-liquid products contain glycerine derived from soya bean. Manufactured glycerine can be derived from animal fat, consequently, you would be correct to ask this question. Totally Wicked only use vegetable glycerine in our e-liquid products. All vegetable glycerine formulated in our products is pharmaceutical grade and contains no alcohol.

Do Totally Wicked e-liquids contain caffeine?

We do not and are, by regulation, not allowed to add caffeine to any UK manufactured e-liquid. Caffeine is not an ingredient in any of our internationally manufactured e-liquid.

Do Totally Wicked e-liquid flavours contain traces of nuts or nut oils?

Our flavour ingredients are produced only at Nut-Free Sites, and none of the materials used in their flavourings contain nuts or substances derived from nuts. This most pertinently applies to the Totally Wicked Diavlo Cyclops Bob flavoured e-liquid (Peanut butter).

Airway allergy advice: Do Totally Wicked e-liquids contain sulphites?

Based on the information disclosed to Totally Wicked for European Regulations (TRPR 2016), we can state our e-liquid do not contain sulphites.

Why is there occasional variation in flavoured e-liquid colour between batches?

There are several explanations for this observation, and they do not compromise the quality of the e-liquid product. The first is that higher concentration nicotine (e.g. 1.8 %) can slightly darken the colour of the e-liquid product, especially after storage at room temperature. This is an expected chemical process, one we have quantified in the lab, and has no impact on the product specification. The second explanation is that from time to time, a flavour concentrate that we purchase will vary in colour between each batch. American Red Tobacco flavouring is an example, one batch can be a straw yellow and the next will be a light brown. This colour variation is a result of the formulation process used by flavour manufacturers, and is accounted for in their own product specification. It has no impact on flavour quality, and our own internal QC checks are applied to each batch of flavour concentrate that we purchase. In the event of any flavour concentrate failing our internal QC tests, it is immediately quarantined and returned to the supplier pending a further investigation.
