Overview
SIST EN 13435:2002 is a European standard published by the European Committee for Standardization (CEN) that provides a specialized analytical method for the determination of free amine content in alkyl dimethyl betaines. These compounds are widely used as surface active agents (surfactants) in cleaning products and personal care formulations. This standard establishes a repeatable laboratory procedure to precisely measure low levels of free amine, a critical quality parameter for surfactant producers and users in Europe and globally.
By stipulating a reliable method for detecting free amine content (ranging from 0.02 mmol to 1 mmol), SIST EN 13435:2002 enhances product quality assurance and ensures compliance with industry and regulatory requirements.
Key Topics
Surface Active Agents
The focus is on alkyl dimethyl betaines, a group of surfactants valued for their mildness and effectiveness in personal care and cleaning formulations.Analytical Method for Free Amine Content
The standard describes a potentiometric titration technique to determine the free amine level, differentiating it from other potential contaminants or reaction byproducts.Non-interference of Common Acids
Monochloroacetic acid, glycolic acid, and strong acids do not interfere with the determination, ensuring that the analysis remains specific to the free amine content.Precision and Repeatability The procedure's repeatability and reproducibility are validated through multi-laboratory testing, making it suitable for routine quality control and compliance monitoring.
Reporting Requirements SIST EN 13435:2002 instructs users on what information must be included in test reports, supporting traceability and transparency.
Applications
Quality Control in Surfactant Manufacturing
Producers use SIST EN 13435:2002 to ensure their alkyl dimethyl betaines meet specified free amine content limits, thus maintaining consistent product performance and avoiding adverse effects in end-use applications.Regulatory Compliance
The reliable determination of free amine content assists manufacturers in meeting both internal specifications and external regulatory standards for chemical content in detergents and personal care products.Research and Development Laboratories and R&D teams apply this standard method to benchmark new formulations or to validate process changes that could influence the free amine content in surfactant products.
Supplier and Buyer Assurance
Adoption of the SIST EN 13435:2002 testing protocol allows suppliers to substantiate product quality claims, while buyers gain confidence in the materials procured.
