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.

ADD-ITC 2026 highlights strong industry participation

The Aachen-Dresden-Denkendorf International Textile Conference (ADD-ITC) 2026 will place a strong focus on the exchange between textile research and industry when it takes place on November 26–27, 2026, at the International Congress Center Dresden. According to the preliminary conference program, more than two-thirds of all presentations will be contributed by companies or jointly presented by industry and research institutions.

Novel flame-retardant and recyclable fiber-reinforced composite

Airplanes and passenger trains must meet strict safety requirements, including fire safety standards. This calls for materials that are flame-retardant, lightweight, robust, and scalable. Empa researchers, in collaboration with their industry partner Elantas, have now succeeded for the first time in making such a material – a composite – fully recyclable.

From smart jackets to laser technology: Mona Neubaur explores Textile Factory 7.0

As part of her summer tour, North Rhine-Westphalia’s Minister for Economic Affairs and Climate Action, Mona Neubaur, visited Textilfabrik 7.0 in Mönchengladbach to experience the project’s innovations first-hand. Under the motto “smart and clean”, the visit focused on innovative technologies and sustainable alternatives for textile production - from smart jackets to the decolourisation of textiles using fungal cultures.

25 years in the room: EDANA’s OUTLOOK™ returns to Cascais to shape a changing industry

The market does not wait, and it does not grant easy answers. Across the absorbent hygiene, personal care, and wipes sectors, business is undergoing a period of intense, necessary adjustment. New European rules on packaging, single-use items, product safety, and end-of-life are forcing companies to drop old assumptions about materials and performance. At the same time, producers must keep their goods safe, reliable, and affordable for the babies and aging adults, who rely on them every day.

Recover™ names Enes Adak and Fehmi Yüksel as Co-CEOs to accelerate its next growth phase

Recover™, a leading materials science company and global producer of consistent high-quality, recycled cotton fibers and circular material solutions at scale, today announced the appointment of Enes Adak and Fehmi Yüksel as Co-Chief Executive Officers. This leadership transition marks an important step in Recover’s evolution as the company enters its next stage of development.

Arc'teryx introduces System 0™, a new framework for the future of product design and circularity

Arc'teryx Equipment, the global design company specializing in technical high-performance apparel and equipment, today introduced System 0™, a new framework that reimagines how products can be designed, manufactured, used, repaired, and ultimately regenerated. System 0 represents the next evolution for sustainability in the outdoor industry, as it embeds circular thinking across an entire product lifecycle while maintaining the uncompromising performance standards that define the Arc’teryx brand.
