Croda Launches Differentiated Tween 20 Polysorbates
March 10, 2014 Croda has launched a new series of polysorbates for the agricultural market that have the same ecological and toxicological benefits as the company’s widely-used Tween 20, but with differentiated performance and physical properties. These products will now allow formulators to have expanded adjuvant options without facing additional regulatory hurdles.
Polysorbates have consistently provided advantages in agricultural applications for over 40 years, with Tween 20 establishing itself as an effective agricultural spray adjuvant for built-in and tank-added applications. It was selected by formulators both for its preferred toxicological properties as well as its performance as a nonionic surfactant adjuvant. Tween 20 effectively delivers multiple adjuvant functionalities such as retention, enhanced uptake, humectancy, wetting and spreading properties making it a top choice in herbicides, fungicides and insecticides.
Croda states that their three new polysorbates, Tween 22, Tween 23 and Tween 24, have the same regulatory status benefits as Tween 20, while offering additional features such as enhanced surface activity for better wetting, lower EST and lower contact angle than Tween 20. The company has confirmed both improved performance with some hydrophilic herbicides and increased uptake with a Neonicotinoid insecticide based on recently generated biological data.
