Stable Formulation of Easy Hydrolizing Actives Based on Specialty Silicas Shown on Malathion as a Modelling Substance.

Source

There are some active ingredients (a.i.) such as phosphoresters which can be hydrolyzed by even the small amount of water available from the surface of natural carriers or synthetic silica carriers. Dry formulations, i.e. wettable powders (WP) and dispersible granules (WG), cannot be formulated with these compounds (Ferch et al. 1990). It has been shown, that the controlled hydrophobicity of the surface of a new type of carrier silica can improve the stability of such a.i., thus, enabling the formulator to produce and apply stable WP and WG.
