AGROCHEMICAL EMULSIONS Russian patent published in 2020 - IPC A01N25/02 A01N25/30 A01N43/40 A01P13/02 

FIELD: agriculture.

SUBSTANCE: agrochemical concentrate of the oil-in-water type emulsion includes: i) a discrete oily phase comprising at least one agrochemical oil-soluble active compound; ii) a continuous aqueous phase, optionally including at least one agrochemical water-soluble active compound; iii) surface-active emulsifier, which is an alkoxylated polyol, which optionally contains a terminal acyl group; and iv) having a lipophilic-hydrophilic balance (HLB) of more than 10 an auxiliary surfactant, wherein the surface-active emulsifier has a general structure (I) R¹*[(AO)_n-R²]_m, in which R¹ denotes a polyol residue, each said polyol contains m active hydrogen atoms, where m is an integer equal to at least 2; AO denotes an oxyalkylene group; each n independently denotes an integer ranging from 1 to 100; each R² independently denotes hydrogen or an acyl group of formula -C(O)R³, where each R³ independently denotes a residue of polyhydroxyalkylcarboxylic acid, polyhydroxyalkenylcarboxylic acid, hydroxyalkylcarboxylic acid, hydroxyalkenylcarboxylic acid, hydroxyalkylcarboxylic acid oligomer or hydroxyalkenylcarboxylic acid oligomer; and in which, on average, at least two groups of R² per molecule are alkanoyl groups.

EFFECT: invention enables to obtain concentrates which are stable in time and during storage at different temperatures.
