Abstract
Oil-based drift control compositions for pesticide or crop protection formulations, that comprise an oil phase, a water soluble polymer, at least one ethoxylated esteramine, at least one alkylbenzene sulfonate and at least one alkyl, aryl or alkylaryl ether phosphate, are readily emulsifiable and are able to maintain the efficacy of agricultural active ingredients applied together with said composition.
Claims8
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:
- 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.
