Detergenttests in the course of time

When it comes to the quality of detergent and cleaning products, one aspect is of paramount importance: do the substances ensure perfect cleanliness? Hohenstein has reliably carried out detergent tests for more than 50 yearsnow, thus makinga significant contribution to ensuring that the quality of detergents and washing agents is very hightoday.

After more than 30 years, Hohenstein is now saying goodbye to the established head of detergent testing, Roswitha Hild, as she retires. Dr Eva Gierling will now take over as her successor from 01/05/2019.

A lot has happened in the detergent market over the past 30 years. Amongst other things, Hohenstein has developed alternatives to the very time-consuming wash and weartests, which havea duration of 22 weeks and thus represents a costly factor for the manufacturers. New products also posed new challenges for the testing facilities. “In 1992, colour detergents entered the market as powder detergents,” remembers Roswitha Hild. “We had to develop new test procedures as, unlike heavy-duty detergents, they also contain an additive to prevent bleeding.”

Internationalisation has also increased significantly in recent years: when it comes to detergent tests, many customers, including global customers such as Dalli Werke, Mifa and Chemolux Germany, have relied on the expertise of Hohenstein for decades.

Dr Gerling is a graduate chemist and has worked for Hohenstein since 2010. She knows the industry: “Our customer structure is slow to change -once someone has worked with us, they often stay for decades.”

Hohenstein’s specialists still test the performance of products with tests of household laundry technology. By conducting comparative detergent tests, Hohenstein ensures improved market transparency, which both consumers as well as retailers and manufacturers expect today. In this regard, practical organisation of the test conditions and the inclusion of current standards and guidelines are particularly important.

Testing and research laboratory ensures safe and more sustainable products worldwide

For 80 years, Hohenstein has stood for independent testing, scientific expertise and practical solutions. Today, the testing and research service provider supports manufacturers and brands worldwide in making textiles, hardlines and medical devices safe, more sustainable and market-ready – thereby building trust among consumers. With an international presence and interdisciplinary expertise, Hohenstein supports its customers from production through to market launch, helping them navigate an environment of growing regulatory and societal demands.

A smarter way to verified Chemical Compliance

Hohenstein and GoBlu Drive Innovation in Sustainable Supply Chain Management As regulatory demands, customer expectations, and sustainability goals continue to grow, the ability to manage chemical compliance and data across complex supply chains has become critical. Hohenstein and The BHive® by GoBlu are initiating a strategic partnership to enhance chemical management in the textile sector. The collaboration delivers more than just a service – it provides an integrated, future-ready solution for brands, manufacturers and suppliers seeking trusted chemical management and credible sustainability.

Hohenstein achieves GLP Certification for Medical Device Testing

Since the middle of July, the testing service provider Hohenstein has been certified to conduct medical device testing in accordance with the internationally recognised Good Laboratory Practice (GLP) standard. This certification comprehensively covers chemical, physical and biological safety testing of medical devices.

Hohenstein supports Global Textile Scheme Initiative

Global testing and research provider Hohenstein has acquired shares in Global Textile Scheme GmbH (GTS). In this way, Hohenstein aims to support GTS in harmonizing and automating data exchange along the entire supply chain. The aim of the GTS initiative is to create an international standard for handling structured product data in the textile and apparel industry.

Award-winning research for sustainable carbon fibre cycles

Sustainable recycling of carbon fibres is possible through targeted electrochemical surface modification, which makes the sizing of carbon fibres resistant to solvolysis. ITA PhD student Sabina Dann was awarded the MSW Award from RWTH Aachen University for her master's thesis on this development. The award ceremony took place on 12 November 2025 in Aachen.

Kick-off for the Textile Production of the Future: Establishment of a Textile Technology and Development Centre in Mönchengladbach, Germany

The Institut für Textiltechnik (ITA) of RWTH Aachen University, together with its partners, is pleased to announce that it has received approval for its joint initiative, ‘Textile Factory 7.0’. The goal of the project is the establishment of a technology and development centre for the textile industry in Mönchengladbach.

Exchange data between textile companies openly, securely and cost-effectively without a central platform – ITA makes it possible

The Institut für Textiltechnik (ITA) of RWTH Aachen University has launched a new demonstrator for an open and secure data space in the textile industry at the Digital Innovation Centre Europe (DICE). For the first time, the demonstrator shows directly and clearly how companies can share their data securely with each other without the need for a central platform. Data exchange is based on shared, freely usable technical foundations.

Advancing the future of stretch: Fashion for Good launches new project to validate bio-based and recycled elastane

Launched today, Stretching Circularity is a collaborative project initiated by Fashion for Good dedicated to accelerating the adoption of lower-impact elastane alternatives that are compatible with circular textile systems. By validating bio-based and recycled elastane solutions through pilot-scale testing and demonstrator garments, the initiative aims to remove one of the most significant technical barriers to a circular textile economy.

Huixing acquires insolvent Mayer & Cie.

Insolvency proceedings for the circular knitting and braiding machine manufacturer Mayer & Cie. were opened on December 1, 2025. Immediately following the opening of proceedings, the complete cessation of business operations was initiated. Most employees were subsequently given notice effective the end of February 2026. The production of the remaining orders in the circular knitting segment is expected to be completed by the end of the month. As early as December 2025, Mayer & Cie.’s braiding machine division was sold to an Italian investor.
