What Are Extractables and Leachables in FDA Context?
Extractables are chemicals released from materials under extreme conditions, while leachables are those that migrate during normal product use. The FDA Extractables and Leachables Case Studies show that even small amounts of these substances can affect a product’s safety, performance, and chemical stability.
FDA testing guidelines focus on risk assessments, Analytical Evaluation Thresholds (AETs), and material compatibility. These ensure that every extractable and leachable compound is detected, measured, and reviewed for toxicological impact.

Complete documentation and traceable procedures are vital. Missing or inconsistent data can cause FDA rejections and product delays. By setting up a clear testing plan early in development, companies ensure compliance and save both time and resources.
Real FDA Extractables and Leachables Case Studies
Case Study 1: FDA E&L Testing for Biologic Packaging
A top biologics manufacturer faced FDA concerns about potential leachables in pre-filled syringes. Through detailed E&L testing, ResolveMass Laboratories identified minor silicone derivatives and polymer residues. After further controlled extractables testing, the FDA granted full product approval.
Key Takeaway: Early-stage E&L evaluation helps prevent FDA rejections and supports faster approvals.

This example shows that detailed chemical analysis during packaging validation can reduce risks, improve product safety, and strengthen regulatory trust.
Case Study 2: Medical Device Compliance Audit
During an FDA audit of a cardiovascular device, inspectors found incomplete E&L records. ResolveMass Laboratories designed a custom E&L study following ISO 10993-18 and USP <1663> standards. The company achieved full FDA compliance within eight weeks.
Outcome: Zero observations in the next FDA inspection.

This case highlights the importance of clear documentation, proper validation, and consistent monitoring. Starting E&L testing early ensures the device remains safe and compliant throughout its lifecycle.
Case Study 3: Drug Product Packaging Failure
A parenteral drug failed FDA submission due to unidentified extractables in polymer containers. ResolveMass Laboratories performed a multi-matrix E&L study and adjusted AET levels according to FDA standards. The revised data led to successful product approval and improved packaging reliability.
Lesson: Correct AET values are key to successful FDA E&L compliance.

FAQs on FDA Extractables and Leachables Case Studies
The main goal of FDA extractables and leachables testing is to ensure that materials used in packaging, containers, and delivery systems do not release harmful chemicals into the product. This testing protects patients from potential toxic exposure and confirms that the product remains stable, effective, and safe for use throughout its shelf life.
The FDA relies on internationally recognized standards such as USP <1663>/<1664>, ISO 10993-18, and ICH Q3D for extractables and leachables testing. These guidelines outline how to design studies, determine analytical thresholds, and conduct toxicological risk assessments. Following them ensures consistency and regulatory compliance across all product categories.
E&L testing should begin during the early stages of product development, ideally when materials are being selected. Early testing helps identify potential risks before large-scale production, reducing the chances of costly delays or regulatory setbacks later. Proactive planning ensures a smoother FDA approval process.
FDA Extractables and Leachables Case Studies often include a mix of advanced analytical tools like GC-MS, LC-MS, ICP-MS, FTIR, and TOF-MS. These techniques detect and quantify volatile, semi-volatile, and elemental impurities with high accuracy. Using multiple methods ensures reliable data and a comprehensive evaluation of all potential contaminants.
The Analytical Evaluation Threshold (AET) defines the lowest concentration level at which a leachable must be evaluated for safety. Setting an appropriate AET ensures that no harmful compounds go unnoticed during testing. Accurate AET calculations are vital for demonstrating toxicological control and achieving FDA approval.
Common extractables include plasticizers, antioxidants, residual monomers, and silicone oils originating from packaging or manufacturing materials. FDA Extractables and Leachables Case Studies show that identifying these compounds early helps manufacturers reformulate materials if needed, ensuring long-term product integrity and safety.
