| abstract |
The present invention relates to a stabilized plant protecting agent suspension which can be characterized by containing 10 to 60% by weight of one or more active ingredients, 30 to 5% by weight of oily layer, 0 to 10% by weight of emulsifier, 10 to 20% by weight of conventionally used excipient and water needed to 100% by weight while by increasing solid concentration oil concentration decreases. The invention also provides a process for the preparation of a stabilized plant protecting agent suspension by adding oil and optionally an emulsifier and/or water containing layer to a suspension of a suitable particle size of the active ingredient and water soluble excipients, such as surfactants, optionally emulsifiers, dispersing agents, viscosity modifying agents, protective colloids and mixing together the suspension layer and the layer containing the oil with a stirrer of great shearing force and optionally adding to the obtained stabilized suspension further excipients, e.g. viscosity modifying agents, anti-foaming agent, protective colloid and dispersing agent. |
