AEROSIL® fumed silica for liquid formulations of agrochemical products

Liquid formulations of agrochemical products occupy an important share in the pesticides market. These formulations are developed to improve safe handling of the active ingredients. Examples for liquid formulations are emulsifiable concentrates (EC), oil dispersions (OD) or suspension concentrates (SC).

The use of AEROSIL® fumed silica supports very much these functionalities as a rheology modifier and anti-settling additive. As an efficient stabilizer AEROSIL® products prevent the agglomeration of active ingredients helping to ensure that they are evenly distributed and show a long-term stability.
