Overview

ISO/FDIS 25202:2026 specifies an internationally recognized method for the determination of glutaraldehyde content in leather materials. Developed by the International Organization for Standardization (ISO) in collaboration with IULTCS, this standard establishes procedures for the chemical analysis and quantification of both free and released glutaraldehyde using liquid chromatography (LC).

Glutaraldehyde is widely used in leather processing for its tanning and disinfectant properties. Accurate determination of its content ensures the quality, safety, and regulatory compliance of leather goods. This standard serves leather manufacturers, testing laboratories, and quality assurance professionals seeking consistent and reliable results in glutaraldehyde analysis.

Key Topics

• Quantitative Chemical Analysis: The standard details a validated LC-based procedure for measuring glutaraldehyde levels in leather, including extraction, sample processing, and derivatization steps.
• Reagents and Apparatus: Guidance is provided on types and grades of chemicals required, including glutaraldehyde solutions, sodium dodecylsulfonate or sodium dodecylsulfate, dinitrophenylhydrazine (DNPH), and acetonitrile. It also specifies laboratory equipment such as thermostatically controlled water baths and LC systems with UV detection.
• Sample Preparation: Leather sampling should adhere to ISO 2418 and ISO 4044, ensuring representative and standardized test specimens.
• LC Calibration and Measurement: The standard describes preparation of calibration solutions and use of reversed-phase LC columns for separation and quantification. It also addresses the use of both direct and DNPH-derivatized glutaraldehyde standards.
• Expression and Calculation of Results: Results are expressed as the glutaraldehyde concentration in mg/kg of leather. Detailed calculation methods using calibration graphs are included.
• Precision and Quality Control: Annexes provide example LC conditions and collaborative study data that demonstrate the method’s reproducibility and detection limits.

Applications

• Leather Manufacturing: Enables tanneries and leather processors to monitor and control glutaraldehyde content, supporting product quality, compliance, and process optimization.
• Regulatory Compliance: Facilitates adherence to international chemical safety and product standards for leather goods.
• Product Testing and Quality Assurance: Provides standardized, reproducible test methods for quality control labs and conformity assessment bodies, ensuring consistent interpretation of results across organizations and jurisdictions.
• Research and Development: Supports innovation in leather processing by providing accurate analytical methods for evaluating alternative tanning chemicals and processes.

Related Standards

• ISO 2418: Leather - Chemical, physical, mechanical and fastness tests - Position and preparation of specimens for testing.
• ISO 3696: Water for analytical laboratory use - Specification and test methods.
• ISO 4044: Leather - Chemical tests - Preparation of chemical test samples.
• ISO 4787: Laboratory glass and plastic ware - Volumetric instruments - Methods for testing of capacity and for use.

By implementing ISO/FDIS 25202, stakeholders in the leather industry can ensure traceable, precise, and internationally recognized determination of glutaraldehyde content. This supports product safety, environmental compliance, and customer confidence in leather products worldwide.

4 Principle
Glutaraldehyde is separated and quantified as a derivative from other aldehydes and ketones by liquid
chromatography. Glutaraldehyde and hydrolysed glutaraldehyde are detected using this method.
The sample is extracted with a detergent solution at 40 °C. The eluate is mixed with 2,4-
dinitrophenylhydrazine, whereby aldehydes and ketones react to give the respective hydrazones. These are
separated by means of a reversed-phase LC method, detected at (355 ± 5) nm and quantified.
