Leachable: Chemical species that migrate from a packaging/delivery system, packaging component, or packaging material of construction into an associated drug product formulation under normal conditions of use or during accelerated drug product stability studies. Leachables are typically a subset of extractables or are derived from extractables.
Extractables and Leachables Information - Thermo Fisher Scientific
Leachables are chemical species that make their way into the product under normal product, application or storage conditions. There is generally an overlap such that the leachables involved may be classified as a subset of the extractables.
What is a Leachable? For a medical device: A leachable is a “substance that is released from a medical device or material during its clinical use”. From: ISO/DIS 10993-18:2018(E). ISO/TC 194/SC /WG 14. Biological evaluation of medical devices —Part 18: Chemical characterization of medical device materials within a risk management process
Leaching (chemistry) - Wikipedia
Leaching is the process of a solute becoming detached or extracted from its carrier substance by way of a solvent. [1] Leaching is a naturally occurring process which scientists have adapted for a variety of applications with a variety of methods.
Extractables and Leachables - US Pharmacopeia (USP)
Extractables and Leachables (E&Ls) are a subset of impurities derived from manufacturing systems, container closure systems, drug product delivery systems, and other packaging material that chemically react with drug product components, including Active Pharmaceutical Ingredients (API) and excipients.

A Short Introduction to Extractables and Leachables in …
Extractable and leachable (E&L) impurities can occur when drug products interact with a wide and complex range of packaging, drug delivery, and manufacturing components. But a lack of internationally-agreed guidance on E&Ls is hampering our efforts to understand them.
Extractables are chemical species that migrate from packaging or container materials into the contents when exposed to certain solvents under exaggerated temperature and time conditions. Leachables are chemical species that make their way into the …
Extractables & Leachables in single-use systems
Leachables are compounds that leach into the drug product from the container-closure system, be it from elastomeric, polymer, other plastic components, or coating materials. Leaching is mainly a result of direct contact with the formulation.
