Textiles must maintain appearance and functionality for a long service life.

Consumer-relevant testing for home laundry.

Customized testing plans focus on consumer- and practice-relevant test methods using naturally soiled domestic linen to support product claims.

Using comparative tests, we investigate diverse factors affecting the performance of detergent, cleaning products and appliances.

We assess the stain removal performance and different aspects of secondary detergency (e.g. material protection and pill formation) in accordance with European testing programs (EU Ecolabel, A.I.S.E. test protocol). 

We also examine washing and drying programs, appliances, modifications to appliances and care additives in detergents and fabric conditioners.

Comparative Product Tests:

  • Softness, through absolute and relative assessment

  • Drying capability/absorption capacity

  • Retention of color tone and surface protection

  • Legibility and clarity of packing information


  • Fabric conditioners

  • Conditioners

  • Dryer sheets


  • Neutral and objective performance comparison

  • Confirmation of special claims

  • Support in the selection of offers

  • Quality control
