Evaluation of cobalt presence in textile colourants
The evaluation of cobalt presence in textile colorants is a critical step in ensuring the safety and compliance of products with international standards. Cobalt, often used as a component in certain dye formulations, can pose health risks if it leaches into clothing or other textiles during wear. This service involves precise analysis to determine whether cobalt is present at levels that could be harmful.
Our approach begins with detailed sample preparation where the colorant is extracted from the fabric under controlled conditions. We employ advanced analytical techniques such as Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for accurate detection and quantification of cobalt. This method allows us to measure trace amounts of cobalt down to parts per billion levels, ensuring reliable results.
The testing process also includes the use of leaching tests which simulate real-world conditions under which textiles might come into contact with human skin or other materials. These tests help assess whether any cobalt could be released from the fabric during normal wear and wash cycles. Our laboratory adheres strictly to international standards such as ISO 14362-1, which provides guidelines for determining migration of elements from textile materials.
Once testing is complete, we provide comprehensive reports detailing our findings including concentrations detected, compliance status against relevant regulations like the REACH Regulation (EC) No 1907/2006, and recommendations if levels exceed safe thresholds. This information is invaluable for quality managers looking to maintain high standards of product safety.
In addition to regulatory compliance, understanding cobalt content helps brands meet consumer expectations regarding sustainability and responsible sourcing practices. By identifying potential issues early on in the supply chain or during development stages, companies can make informed decisions about ingredient selection and process improvements. Our team works closely with clients throughout this service ensuring all necessary steps are taken efficiently.
