In the increasing market of wet wipes for Hard Surface Cleaning, more and more diversification can be observed. Consequently, wet wipes producers are constantly looking for new claims and innovative performance effects. This can be achieved through design of the wipe material as such, or the choice of ingredients for the liquid phase.
Key parameter in the design of specialty polymers is the surface modification of both soft and hard surfaces. In this lecture, two polymers with the focus on potential application benefits in hard surface cleaning wet wipes shall be presented.
The first polymer is designed to be able to prevent surfactant residues on shiny surfaces. As wet wipes are usually used without a subsequent rinsing step, the feature of leaving the surface streak-free is highly important, especially when using the products on glossy glass and ceramic surfaces.
The second polymer is known as a Soil Release Polymer, broadly used in laundry detergents. These polyester based polymers are known to be able to modify polyester fabrics. When applying these polymers to wet wipes, the wipe will be hydrophilized, facilitating the wetting performance. Soil Release Polymers in addition have a strong dispersion power, and help to remove greasy stains. Being very mild to the human skin, these polymers can readily be used in applications with direct hand contact.
