Novel formulation additives, production and use thereof

Abstract

The invention relates to novel formulation additives of formula 1 and to the production and use thereof, in particular as adjuvants and additives for agrochemical formulations. A novel combination of known ether sulfates and cations allows products with superior characteristics to be obtained, such as pesticides with improved strength.
