The sorbitan ester and polysorbate series products under the Huana brand are all nonionic surfactants. Nonionic surfactants dissolved in water can help to remove dirt and grease from many different solids. Nonionic surfactant molecules have hydrophilic and hydrophobic effects. In cleaning products, the hydrophobic effect prevents dust and oil from entering the re-cleaned surface, while the hydrophilic effect helps disinfect the surface. This is why many household cleaners contain nonionic surfactants.
There are many types of surfactants with different properties, and their respective characteristics determine which cleaning products are most suitable and how they can adapt to water hardness. Nonionic surfactants have uncharged molecules, which makes them resistant to changes of water hardness and are very suitable for washing powder, toilet cleaner and detergent.
Washing powder has both anionic and non-ionic surfactants. Anionic surfactants have a negatively charged head, which gives them excellent cleaning performance and high foaming potential, and complements the resistance of nonionic surfactants to hard water inactivation. Toilet bowl cleaner must resist hard water. This is why most manual and automatic toilet cleaners use nonionic surfactants. In addition to resisting hard water deactivation, nonionic surfactants are also good at removing grease. This makes them very good at cleaning dishes. The hydrophobic effect mixes and captures the grease, and prevents the grease from reattaching to the tableware.
