We provide chemical-technological testing and analysis services of the highest quality to ensure legal conformity and product safety in key sectors such as tattoo and permanent make-up, textile, furniture, leather, colourants, toys and the automotive industry.

With our test report and our CTL seal we aim to guarantee the safety and innocuousness of products. To achieve this we work with the utmost care - accredited, precise and innovative - and we stay close to our customers.

• Quality and precision: highest standards, confirmed by accreditation to DIN EN ISO/IEC 17025:2018.
• Family-run: at CTL everyone interacts as equals.
• Independence and impartiality: as an independent laboratory, with no ties to manufacturers, we guarantee objective and reliable results.
• Continuous innovation: we develop advanced test methods, for example for identifying azo dyes or distinguishing pigments from dyes.
• Global engagement: we work worldwide with customers and authorities and consistently meet the highest regulatory requirements.

Together with manufacturers and supervisory authorities we work to ensure that products are safe for people and animals. Our goal is to help our customers meet their social and environmental obligations, because our testing supports them in developing and validating high-quality, safe and responsible products. We also actively support the development of new products at every stage through our technical advice and analytical expertise.
