E-liquid Testing

Know what you're buying

Totally Wicked Mark of E-liquid Excellence

With an ever-expanding e-liquid industry, and an ever-expanding body of knowledge regarding e-liquids, it is vitally important to understand exactly what you are buying.

To this end we offer a guarantee of e-liquid excellence for our customers. Our guarantee is not only our promise to you that we will always do over and above what is required of us, to ensure the best quality e-liquids, it is also a reassurance for you, enabling you to understand fully exactly how we manufacture our e-liquids, and the safeguards we have put into place.

All our 'Made in UK' ranges, are made by Totally Wicked in our own sector-leading facility. We know with full trace-ability where all our ingredients come from; they are all made to GMP (good manufacturing practice) standards and all are sourced from within the UK. We were one of the very first companies to use and continue to use pharmaceutical grade diluents and nicotine, and all our flavourings are GRAS (generally recognized as safe) food grade. The flavour concentrates we use have also been screened for inhalation suitability by a team of highly qualified scientists and toxicologists.

Our Titan and Patriot ranges, produced by our manufacturing partners, are also assured and tested to identical quality standards as our “made in the UK” e-liquid. We source our fluid from suppliers only where we have assured ourselves that we are content with the safety and quality they provide. We build long-term relationships, and we demand and assure both quality and consistency by working closely with all our suppliers. Indeed, we take the responsibility for the nicotine quality as seriously as having our UK pharmaceutical grade nicotine shipped to the USA for inclusion in our exclusive Patriot E-liquid range.

Our e-liquids have been thoroughly tested for flavour inhalation safety under a strict analysis regime specified by Dr Konstantinos Farsalinos, one of the world’s most eminent e-cigarette researchers. Totally Wicked e-liquid is certified free from diacetyl, 2,3-pentanedione, and acetoin by in-house validated GC-MS/FID analytical test methods (subject to LOQ of analytical method). See below links to laboratory certificates of analysis.

  • Our e-liquids are made in a sector-leading e-liquid manufacturing facility, using highly precise metering of quantities, effective quality systems, and in-house QC laboratory.
  • All batches are carefully sampled and recorded, with complete trace-ability to enable investigation or recall should any batch issue ever be detected.
  • We ensure we provide all the correct and required information and that the bottles comply with child-resistant ISO and CLP standards.

Our manufacturing standards, specifications and test regimes are constantly reviewed as research data drives the industry standards to higher levels, and we will be at the forefront of this.
