Cognis Offers Disponil NG, Non-Ionic Surfactants
Cognis has launched Disponil NG series of APEO-free, VOC-free and FDA-approved surfactants. In accordance with Cognis Greenovating strategy, the Disponil NG series seeks to bring sustainability and performance together: based on renewable raw materials, the Disponil NG series offers several benefits in the emulsion polymerization process as well as in end users applications, such as being gel-free, showing fast foam decay and having low pour points. The Disponil NG series of surfactants are based on modified natural and renewable-based fatty alcohols combining performance, handling and environmental soundness, according to the company. The Disponil NG series comprises surfactants that are suitable for all types of latices as in-process non-ionic or as post-stabilization surfactants. They show excellent phase behavior, meaning that when diluted with water, there are no gel phases over the entire concentration range. Additionally, they ensure rapid foam collapse in the surfactant solution as well as the finished latex, and they have low pour points even lower than -15C. These properties result in easier handling and reduced energy consumption during latex production compared to traditional surfactants. Emulsion production times are reduced, and the manufacturing process can continue even at very low temperatures.
