Say goodbye to polyquaternium stains with Smart Shield
Our R&D team has developed Smart Shield, a special liquid additive that prevents the formation of dark stains caused by polyquaternium-7 in shampoos and shower gels offered by hotels to guests. These stains are colourless and transparent, making them difficult to identify before washing. Smart Shield neutralises the positive charge of the polyquaternium molecule, resulting in no attraction of dirt to the polymer, thus avoiding rewashes and making laundry duties a breeze.
