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.

A new standard to combat plastic waste in forests

With DIN SPEC 35808 “Tree Shelter for Forestry Applications,” the testing and research service provider Hohenstein, in collaboration with Rottenburg University of Forestry, as well as forestry authorities and industry partners, has established a clear framework for bio-based and fully biodegradable tree shelters. The pre-standard defines requirements and practical testing methods designed to reduce plastic waste in forests and strengthen the long-term protection of soil and the environment.

Hohenstein publishes 2025 Sustainability Report

The testing and research service provider Hohenstein has published its latest sustainability report, outlining key progress and strategic initiatives. The report focuses on ambitious CO₂ reduction targets, the company’s new mission statement and the systematic expansion of sustainable services for customers worldwide.

New DIN SPEC assesses environmental impact of textile fragments in soil

Textile products made from synthetic fibres, finished fabrics or dyed materials release fibre fragments into the environment at every stage of their life cycle. With the new DIN SPEC 19296, Hohenstein has developed a standardised testing method to analyse how these fragments behave in soil under natural conditions. Until now, little was known about their environmental behaviour or potential ecological effects once released.

Aachen Summer School: Textiles become smart through 3D printing and origami

From 21 to 29 September 2026, the Aachen Summer School will transform Institut für Textiltechnik (ITA) of RWTH Aachen University into a laboratory of the future: over the course of a week, students will use origami folding techniques and 3D printing to develop active textile structures capable of performing programmable movements. This interdisciplinary event combines theoretical foundations with practical prototyping – from digital modelling right through to functional textile prototypes.

25 years of medical devices: ITVP combines experience with innovation

ITV Denkendorf Produktservice GmbH (ITVP) is celebrating its 25th anniversary. On October 1, 2001, ITVP was founded as a subsidiary of the German Institutes of Textile and Fiber Research Denkendorf (DITF), Europe’s largest textile research center. This spin-off company made it possible to consolidate expertise in medical technology and significantly expand production, which had previously been initiated mostly in the DITF’s cleanrooms.

An eco-friendly alternative to fluorocarbon treatments

Protective and outdoor clothing derives its durable water-, dirt- and oil- repellent properties from the application of fluorinated polymers or per- and polyfluorinated low-molecular- weight chemicals (PFCs). The beneficial properties thus achieved on textiles are offset by environmental and human health risks. For manufacturers of sports, medical, protective and automotive textiles, researchers at the Sächsisches Textilforschungsinstitut e.V. and the Leibniz Institute for Polymer Research have developed liquid-applied dispersions and solutions to functionalise textiles without the use of fluorine.
