US 6,586,366 B1 · Homogenous agrochemical concentrates and agrochemical formulations obtained therefrom

Abstract

Oil based emulsifiable concentrates include (a) at least one oil component; (b) at least one surfactant hydrocarboxyl saccharide, particularly a surfactant hydrocarbyl polysaccharide (HPS); and (c) at least one other non-ionic surfactant. The concentrates are typically homogeneous for at least 24 hours and emulsify readily on dilution into water. The concentrates preferably also include: (d) an antifoaming agent, especially a polysiloxane; and/or (e) at least one chemical agent specific to the intended use of the composition, such as an agrochemical, especially a herbicide, or a metal corrosion inhibitor. The concentrates can be diluted readily in water to give emulsion formulations which can be sprayed onto substrates, e.g. when the chemical agent is a herbicide, onto weeds.
