Testing for the best: Detergent research at Persil

Persil is a detergent that sets itself particular challenges – and has been for some 100 years now. Purity, performance and the protection of textiles are at the centre of our research and development in order to achieve the best result for you – always.

The variety of materials and textile configurations has never been greater than today. All the more reason to do justice to these materials with a suitable detergent – so that you can enjoy your favourite pieces for the long term. Your textiles are to be clean and stain-free, colours should remain brilliant and the fabric should be as beautiful as on the first day.

In order to achieve that, a great many elaborate tests are conducted, because that's the only way we can ensure that we're offering you reliable quality.

A small overview of the different tests:

Frequently occurring soiling such as cocoa, make-up, lipstick,  and machine oil are applied to pieces of laundry with a special stain-applying machine. The even, almost identical stains result in ideal conditions for comparative washing tests that are conducted with 400 washing machines of various manufactures or various countries of origin.

That means we wash and then evaluate 2.2 million stains every year. We're able to check whether the textiles are affected by greying or whether the colours stay intact in our matching room under special, constant light conditions.  
In the climate chamber with constant humidity, the textiles are then tested for tensile strength, roughening of the surface and slubs.

These procedures enable us to realize our vision: to be a leader in brands and technologies that make life easier, better and more beautiful for you.
