« Back Friday, November 14, 2008 Rhodia - The Soprophor® Series Tristyrylphenol-Based Surfactans for Agricultral Applications Tristyrylphenol (TSP)-based surfactants are a core component of Rhodia’s formulation additives portfolio. They are unique for the physicochemical properties they provide in formulations, and for their toxicological and ecotoxicological properties. TSP-based surfactants provide significant performance advantages over classic surfactants such as nonylphenol ethoxylates due to the unique size and structure of the hydrophobe. Nonionic Soprophor products are synthesized by ethoxylation or ethoxylation-propoxylation; anionics are prepared from ethoxylated tristyrylphenol by phosphation or sulfation. Rhodia’s extensive line of TSP-based surfactants provides formulators with the right tools to perfect any agrochemical formulation. Why Choose Soprophor® Surfactants: High Affinity for Active Ingredients Versatile Emulsifiers and Dispersants Excellent Colloidal Stability Lower Phytotoxicity (compared to nonylphenol 10EO) Good Toxicological Profile More Efficient in Milling Processes Due to Strong Interaction with Organic Active Ingredients For more information on the Soprophor Series, please contact your local Walsh sales representative.
