Patent ID: 8470742

Claim:
A method of making an agrochemical spray formulation, comprising: diluting a homogeneous and self-emulsifying oil-based agrochemical concentrate composition with water to form an agrochemical spray formulation that comprises an agrochemical; wherein the self-emulsifying oil-based agrochemical concentrate composition, comprises: a) from 30 to 60 parts by weight of at least one oil component; b) from 15 to 40 parts by weight of at least one non-surfactant saccharide, present in solution; and c) from 5 to 45 parts by weight of at least one non-ionic surfactant of the formula: R 1 —O-A n R 2 (I), or R 3 —N-(A n R 2 ) 2 (II); and d) at least one of the following additional components: i) from 1 to 20 parts by weight of at least one surfactant hydrocarbyl saccharide; ii) from 1 to 20 parts by weight of at least one anionic surfactant; or iii) from 1 to 20 parts by weight of at least one further non-ionic surfactant; wherein: R 1 represents a hydrocarbyl, hydrocarbonyl, or hydrocarbamidyl group having from 6 to 24 carbon atoms, a glycerol or polyglycerol group, or a sorbitan or sorbitol group; A represents a polyalkylene oxide unit containing an average of n alkylene oxide groups or mixed alkylene oxide groups, wherein the alkylene groups each have 2 to 8 carbon atoms; n represents between 0 and 40; R 2 represents hydrogen or hydrocarbonyl residue having 8 to 22 carbon atoms, or a polycarboxylic acid residue of malate, fumarate, maleate, succinate, or citrate, or an oligomer thereof; and R 3 represents a hydrocarbyl or hydrocarbonyl group having 8 to 22 carbon atoms; and wherein the total surfactant comprises from 10% to 50% by weight of the concentrate.
