NZ 600551 The disclosure relates to an emulsified concentrate for a macroemulsifiable phytosanitary composition comprising: more than 90 wt% of at least one hydrocarbon mixture having a distillation cut greater than 250 DEG C, said emulsifiable concentrate comprising less than 20 wt% n-paraffins, less than 1 wt% aromatics, and from 1 to 4 wt% of a mixture of at least two surfactants TA1 and TA2 such that TA2 is more hydrophobic than TA1 for a difference in HLB between TA1 and TA2 varying from 3 to 11 and the HLB of the mixture of which varies from 6 to 10 and comprising from 0.0001% to 1% by weight of water, wherein the surfactant TA1 is chosen from the polyalkoxylated carboxylic acids, comprising a carbon chain with 16 to 20 carbon atoms having at least one olefin bond, each polyalkoxylated group comprising from 3 to 15 alkoxylated radicals, itself comprising from 1 to 4 carbons per oxygen atom, the HLB of said TA1 varying from 5 to 16 and the surfactant TA2 is chosen from sorbitan mono- and/or polycarboxylates, polyethoxyated sorbitan mono- and/or polycarboxylates, glycerol mono- and/or polyethoxylated, polyethoxylated glycerol mono- and/or polycarboxylates, each polycarboxylate group comprising 1 to 3 carbon chains of 12 to 20 carbon atoms having at least one olefin bond, the polyethoxylated group comprising 1 to 5 ethoxylated groups, the HLB of said TA2 varying from 1 to 11 preferably, the surfactant TA1 is chosen from the polyethoxylated oleic acids comprising from 4 to 8 ethoxylated radicals and the surfactant TA2 is a sorbitan monooleate or a glycerol monooleate or their mixture.
