Comparative product tests – for greater market transparency
Just how good is your product really – when compared directly with the competition or with your previous model? Hohenstein’s comparative product tests provide you with the answer: objectively, transparently and based on scientifically sound testing methods.
We examine the quality-determining and consumer-relevant characteristics of your product in a direct comparison – with competitors’ products, with new developments or with successor products to existing items. This provides you with:
- neutral proof of quality for your customers
- an objective basis for decision-making regarding your internal quality control and product development
- clear insights into your product’s strengths, weaknesses and potential for improvement
Verifiable results to back up your marketing claims
Claims such as ‘removes stains particularly thoroughly’, ‘particularly long-lasting’ or ‘cleans particularly effectively’ are only convincing if they can be substantiated – both to consumers and to retailers and competitors.
Comparative product tests by Hohenstein provide you with precisely this evidence: as an independent, accredited testing laboratory, we underpin your advertising claims with objective, reproducible test results. This enables you to scientifically substantiate your product communication, meet regulatory requirements and build trust with your customers.
You can also display positive test results directly on the product: with a Hohenstein Quality Label or a test certificate that makes your verified product quality immediately recognisable to consumers.
Specifically for cosmetic products, we also offer our own claim support service: Using mini-application tests (use tests) on panellists, we assess the effectiveness of your products in a real-world setting, supplemented by a labelling review to ensure compliance with regulatory requirements – such as the EU Cosmetics Regulation (EC) No 1223/2009. This provides you with bespoke, consumer-focused testing services backed by the full confidence of an accredited, independent testing laboratory.
Standardised testing methods – or tailored precisely to your product
Wherever possible, we use standardised test methods, for example in accordance with DIN, EN or ISO. This ensures that our results are comparable, reproducible and widely recognised. Our wide range of physical and chemical tests forms the basis for this.
However, there is not always a suitable standard for every product and every issue. In such cases, we adapt or modify existing test methods as required – or work with you to develop a bespoke test plan that realistically simulates the actual conditions under which your product is used. For properties that can only be assessed on humans, we also carry out human trials with specially trained panellists. This ensures you receive meaningful results, even for innovative or highly specialised products.
A wide range of products that can be tested
We have been carrying out comparative product tests on behalf of manufacturers, retailers and consumer organisations since the 1950s. This experience has led to the development of a testing portfolio that extends far beyond traditional textiles:
- Textiles and clothing
e.g. softshell jackets, men’s shirts, denim, bed linen, sports and functional clothing - Textile-related consumer goods
e.g. paper handkerchiefs, kitchen roll, lint rollers, school bags - Household appliances (white goods)
e.g. washing machines and tumble dryers – tested using our globally unique, real-world testing system.
Related topics: Domestic textile care - Detergents and laundry agents
e.g. all-purpose and colour detergents, stain removers, fabric conditioners – tested in accordance with standardised procedures such as the EU Ecolabel, IKW recommendations and the Detergent Europe Test Protocol (formerly A.I.S.E.)
