1. An oil-based drift control composition consisting of:
a) from 40 to 80% by weight (wt %) of an oil phase;
b) from 1 to 15 wt % of a water soluble polymer as drift reducing agent;
c) from 5 to 20 wt % of at least one ethoxylated esteramine of formula I:

OG Complex Work Unit Chemistry
wherein:
R, R′ and R″ are each independently alkylene group having from 1 to 8 carbon atoms;
X, Y and Z are selected among H, O—(CH2CH2O),H, O—(CH2CH2O)n-COR′″ or O—COR′″ and one of X, Y and Z is O—(CH2CH2O)n-COR′″ or O-COR′″;
wherein n=1-10;
R′″ is a saturated or unsaturated C6-C30 alkyl group, provided that:
i) when one among X, Y or Z is O—(CH2CH2O)nCOR′″, the other two substituents are each independently H or O—(CH2CH2O)nH—
ii) when one among X, Y or Z is O—COR′″, the other two substituents are H or O—(CH2CH2O)nH and at least one of them is O—(CH2CH2O)nH;
d) from 3 to 10 wt % of at least one alkylbenzene sulfonate;
e) from 0.5 to 5 wt % of at least one alkyl, aryl or alkylaryl ether phosphate;
f) from 0 to 15 wt % of water;
g) from 0.5 to 5 wt % of a thickening agent; and
h) from 0.5 to 15 wt % of a water soluble organic solvent.
