E-Liquid Testing Labs in the UK

E-Liquid Testing Labs in the UK

By Ekaterina Mironova

Vapers everywhere know that although the last part of the new TPD laws doesn't go into effect until May, most e-liquid wholesalers and resellers have already taken action to comply with them. It should be noted that despite the fact that there have been a lot of complaints about the law E-Liquid analysis is an essential part of protecting the public and guaranteeing E-Liquid high-quality standards. While most E-Liquid sellers strive to maintain excellence in the products they sell, these type of laws are necessary to protect the public from slackers who don't. Here are some of the practices which E-Liquid testing labs in the UK are currently following to ensure that the new rules are followed:

E-Liquid Analysis

When it comes to E-Liquid Analysis, most laboratories in the UK provide a wide range of options for your business needs, which include the basic standard batch testing, if you just want the bare essentials, to TPD-driven analysis, which is the ultimate in E-Liquid Analysis.

Standard Batch Testing

This is the simplest of the choices offered, however, you might want to go even further to be absolutely certain that you are meeting the requirements of TPD. Standard batch testing reveals the amount of nicotine present in the E-Liquid, and checks if there is any diacetyl, acetyl propionyl or acetone present. This process, as all available processes do, requires an expert team of knowledgeable, professional analytical chemists who work together with consultant toxicologists in order to locate those E-Liquid compounds which are possibly toxic, and to create proven ways for ferreting out these analytes in both vapor and liquid form.

Standard batch testing can supply further batch quality data which can come in handy, like specific gravity and product density, etc.

E-Liquid Laboratories

Many E-Liquid sellers and resellers are now building their own Analytical Laboratories which carry all the necessary tools to determine the chemicals in E-Liquid and emissions to TPD satisfaction. They use their own singular approaches, determined to be the best, plus varying ways of chemical testing and top notch instruments to find and resolve their client's TPD compliance difficulties.

In creating these laboratories, the companies aren't reluctant to spend big bucks either, providing, of course, that they can afford to do so. They are committed to staying in business and that means satisfying not only the demands of TPD, but their customers desires too. Thus they are even agreeable to investing yet more of their financial capital in new equipment as needed, plus delivering relatively inexpensive and timely analyses.

E-Liquid Batch Search

At least one well known laboratory has created a function which permits clients to see the entire analysis of their E-Liquids in a simple, user friendly way. With the development of this new technology, it is almost certain that other labs will be clamoring to learn its secret so that they can do the same for their clients.

Not only should the E-Liquid be analyzed, but should your brand of E-Liquid fail the tests required by TPD, the lab will then assist your company in reaching those standards, and yet keeping your unique flavor.

Technical Dossier

Under orders by the TPD a technical Dossier must be issued for all flavors of E-Liquid which are sent in to the Medical Health Regulatory Authority (MHRA).

One of the main demands for this dossier is that a complete Toxicological Risk Assessment (TRA) be conducted for each E-Liquid flavor. Any lab should be able to put together this Technical Dossier to prove that your business is in full compliance with the law.

  • Here are the services you should receive:
  • Complete analyses of your product
  • Toxicological Risk Assessments
  • Complete and accurate toxicological data sets
  • Complete and accurate Technical Dossier and submission

For the most part the TPD regulations are clear and concise, and meeting them isn't difficult, there is, however, one requirement that is a bit troubling. The Technical Dossier needs to:

  • Provide information concerning the administration which would include descriptions, address and all declarations.
  • Supply an entire set of toxicological data for every individual chemical component.
  • The entire chemical composition must be written out.
  • Send a Toxicological Risk Assessment for each product.

Toxicological Risk Assessment

  1. Toxicological Determination --Registered toxicological companies are used to create the toxicological ingredients of more than 300 single chemical components, which have been chosen because primarily they make up the base ingredients of most of the flavor concentrates out there. Every single chemical is evaluated for possible negative effects.
  1. Compositional Determination --Every E-Liquid must have its chemical makeup determined and tests must bear this out. Most laboratories have special equipment which performs the chemical composition analysis of all E-Liquid and vapor which passes through their doors before giving it their stamp of approval.
  1. Thermal Degradation --When e-cigarettes are in use, the atomizer coil can raise temperatures to 300 degrees or more. In the face of such extreme heat, some chemicals are apt to degrade. That's why it is essential to look into all possible methods of chemical degradation.
  1. Toxicological Risk Assessment --Taking advantage of the data collected in prior stages a full TPD compliant Toxicological Risk Assessment (TRA) is then done for the particular E-Liquid flavor the company wishes to promote.
  1. Submission --The Technical Dossier is checked and submitted to the MHRA.

Distinctions Between E-Liquid Testing Labs in the UK

The best laboratories for E-Liquid testing to make sure your products are TPD compliant have scientists who have made E-Liquid analysis their speciality, working in the lab's very own E-Liquid Analytical Laboratories. Thus they already have cultivated an interest in this type of chemical analysis and are experienced professionals who know exactly what they are doing.

Dealing With the TPD

All Analytical Laboratories should be precisely equipped to supply complete analytical services to guarantee their client's E-Liquid brand meets the standards set forth by Article 20 of the Tobacco Products Directive (TPD), which has been in effect since May 2016, and the future regulations which will become effective in May of 2017. They should also offer a Toxicological Health Assessment (THA) so that they can ensure TPD compliance with one time full service.
