Smart shield protects your towels from polyquaternium stains

05/12/2019

Polyquaternium stains are a frustrating phenomenon in many laundries that wash hospitality linen. Polyquaternium-7 is often found in shampoo and shower gels which hotels offer to their guests. Unfortunately, this polymeer causes dark spots on freshly washed towels. What is even more frustrating is that these stains are transparent and colourless, making it difficult to identify them before washing. The result? Rewash.

To avoid these stains and the rewash associated with it, Christeyns developed Smart Shield, a special liquid that neutralises the positive charge of the polyquaternium-molecule. In this way, the dirt is no longer attracted to the polymer and stains will no longer appear.
