Quality – Our benchmark from the beginning
Quality that is second to none
When it comes to our products, we give quality, safety, transparency and purity the top priorities.
All our products are fully developed and manufactured in Germany. We ensure that all our ingredients are absolutely pure and we are the very first e-liquid manufacturer to have put in place a system that allows full traceability of our products. We can thus offer you not just high-quality e-liquids but also guarantee you a risk-free vaping experience.
Quality and safety
The name 'happy liquid' is synonymous with premium quality, safety and innovation in the vaping sector. All our flavor ingredients conform to the requirements of German foodstuff legislation and we continually strive to improve our products.
But our quality and safety claims are not just restricted to our ingredients ‒ we can also guarantee that our flasks are free of softening agents. Our holistic approach to quality management has set new standards in the German e-liquid manufacturing industry and ensures you will not be placed at risk when you vape our products.
"Test all things, and keep hold of the best."
Johann Wolfgang von Goethe (1749 - 1832)
German author, scientist and statesman
Nicotine and nicotine levels ‒ a strength for every vaper
We use only natural L-nicotinein its purest pharmaceutical quality in our happy liquid products. This produces the stimulating and relaxing effects otherwise experienced on smoking tobacco.
Our products come in five different nicotine strengths: From 'zero' for those who want to enjoy the pure taste only to 'high' for the heavier cigarette smoker.
Our nicotine levels:
- 'zero'(0 mg nicotine) for those who want to enjoy the pure taste
- 'extralight'(3 mg/ml) for very low nicotine requirements (available in the sub ohm range only)
- 'light'(6 mg/ml) for low to normal nicotine requirements
- 'medium'(12 mg/ml) for normal to moderate smokers
- 'high'(18 mg/ml) for heavy cigarette consumers
The various strengths are easily and safely recognizable from the individual label colors as well as the standard label imprints.
Please note that not all nicotine strengths are available with all base liquid variants.
Selecting the right nicotine strength
For those starting vaping or switching from smoking to vaping, selecting the right nicotine strength can be a bit of a problem. Every individual has a different nicotine requirement so that there is really no rule of thumb that can be used. In addition, the amount of nicotine released will be determined by the individual vaping technique and type of e-cigarette employed.
Ingredients and blend
It is not only quality and purity on which we place emphasis ‒ just as important to us is the flavor of our products.
- Propylene glycol (PG)
- Vegetable glycerin (VG)
- Bi-distilled water
- Flavoring(natural/nature-identical)
- Nicotine (except in 'zero' products)
The purity of our ingredients complies with the corresponding requirements of the relevant pharmacopoeias (DAB, EU, Ph, and USP). So you can rest assured you can vape safely. To ensure the best combinations of flavor, we use three liquid bases that we have developed in-house.
Our liquid bases
- PG bases (contain 80% propylene glycol, 10% vegetable glycerin and 10% bi-distilled water)
- VG bases (contain 60% vegetable glycerin, 20% propylene glycol and bi-distilled water)
- Sub ohm bases (contain 70% vegetable glycerin and 30% propylene glycol
Our PG range is particularly intense in terms of flavor. You'll experience the full taste and fine nuances. This is because PG is the substance in e-liquids that is mainly responsible for the transport of flavor. We only use PG in its purest form, the same as that used in cosmetic products such as toothpaste and creams.
Our VG range produces intensive vapor. However, the properties of vegetable glycerin mean that it is not suitable for use with all flavor variants. It tends to 'absorb' flavors that are too delicate, thus reducing their intensity. Our range thus only includes selected types of flavor in combination with higher level VG concentrations.
In the case of our sub ohm range we have created blends designed to enhance the vaping experience. Our sub ohm bases are also only available in certain selected flavor variants.
You can recognize our product bases by the designations on the labels ‒ either PG, VG or Ω.
Many of our liquids are also colorless. This is because we use no coloring agents whatsoever. The intensity of color is determined by the corresponding nicotine strength, among other factors.
The bases we produce are characterized by their outstanding flavor developmentand excellent generation of vapor on use in all commercially available vapes.
Development and production
Made in Germany: From the production of bases to filling and labeling ‒ every stage of manufacture is undertaken in our in-house laboratory.
Reliability: We source all our ingredients from dealers in Germany with whom we have already worked closely over years.
Transparency: We produce our bases from tested and certified ingredients. It is thus possible for us to ensure traceability and safety

Analysis and certificates
As far as we are concerned, all our customers have the right to transparency!
happy liquid is the world's first e-liquid manufacturer that has published studies and undertakes animal-free product testing. Our flavor ingredients are not only required to conform to the requirements of German foodstuff legislation but must also pass our stringent in-house quality tests. In addition, we also subject our products to Ames testing and can thus confirm that they have no mutagenic potential in the human body.
Research and development
We actively promote reasonable policies for the regulation of e-cigarettes and e-liquids. We thus already conformed to the corresponding requirements introduced with the revision of the Tobacco Products Directive (TPD2). To make sure we are always informed on latest developments, we regularly attend international congresses and provide funding for research.
