Extractables and Leachables

Extractables and leachables studies establish the safety of an Electronic Nicotine Delivery Systems (ENDS) product by investigating, identifying and monitoring the wide variety of compounds that may be present in either the delivery device or the e-liquid; and which may therefore present an exposure risk to your end user. The study will inform which compounds have the potential to be present in your product, which compounds are positively identified in your product routinely, and which compounds may develop a presence in your product over its lifecycle. These compounds may find themselves in the aerosol inhaled by the end user, or be introduced to the end user by direct contact, such as oral contact with a mouthpiece. A well designed and implemented extractables and leachables study will demonstrate that all safety concerns have been considered and is key to a successful submission.

What is Extractables and Leachables analysis?

Extractables analysis of ENDS products

Extractables analysis is focused on an ENDS device or container and the materials used to form them. The objective of the study is to identify compounds that could potentially be extracted from a device or container under a range of conditions designed to interrogate the materials. Dependent upon the product profile, numerous extraction conditions may need to be employed to identify potential compounds, such as:

Leachables analysis of ENDS products

Following examination of the findings from the extractables study, a subsequent leachables study is conducted focusing on how your ENDS device and/or packaging material interacts with a specific e-liquid.

To ensure that the leachables study is tailored and relevant to the extractables identified, our in-house registered toxicologists will perform a toxicological assessment to identify the level of concern associated with any identified extractables.

Our on-site temperature and humidity controlled stability chambers will allow stability data to be obtained to meet the requirements for demonstration of shelf-life conditions. The objective of the leachables study is to identify and quantify analytes of concern that are confirmed to migrate from the device or container into the e-liquid, or to the end user by direct contact, under typical use.

Our team of experts will work to develop and validate methods for analysis of targeted leachables to ensure reliable and robust data specific to your product.

A study tailored to your ENDS product

Extractables and Leachables assessments are most effective when tailored to an individual product. At Broughton Nicotine Services we take the time to discuss your product with you to thoroughly understand your needs, timelines and resourcing requirements to support your regulatory submission. Upfront planning is essential as decisions made early in the process can have important implications later through the process.

Our team also understand that ensuring progress in line with agreed schedules is one of the highest priorities of ENDS companies. Hence we prioritize and adapt to respond to changes and achieve your agreed milestones.

Our team of experts, with their collective years of experience in the ENDS sector, including regulatory expertise, registered toxicologists, dedicated development and validation scientists, and an ENDS dedicated experienced analytical team, are focussed purely on this industry and have the level of understanding required to design your study with you to maximise the efficiency and value of the testing.
