Non-foaming organic surfactants as additives for tank mixture preparations in crop protection
View Patent ↗Use of special non-foaming alkoxylated alcohols alone or their mixture with polysiloxanes as tank mixture additive for crop protection composition formulations.
1. A method of reducing dynamic surface tension and/or foaming of a crop protection composition which comprises adding an alkoxylated alcohol of formula 1
R 1 O(SO) a (PO) b (EO) c (BO) d R 2 (Formula 1)
where
SO =styryloxy =—CH (C 6 H 5 ) —CH 2 —O— or
—CH 2 —CH(C 6 H 5 ) —O—,
PO =propyleneoxy =—CH (CH 3 ) —CH 2 —O— or
—CH 2 —CH (CH 3 ) —O—,
EO =ethyleneoxy =—CH 2 —CH 2 —O—,
BO =butyleneoxy =—CH 2 —CH 2 —CH 2 —CH 2 —O—,
a =0 to 1,
b =0.5 to 4,
c =1 to 5,
d =0 to 1 and
R 1 is a 3,5,5-trimethylhexyl radical,
R 2 is an alkyl radical having 1 to 4 carbon atoms, an acyl radical, or a (meth)acryloxy radical, or is a hydrogen radical, as a tank mixture additive to the crop protection formulation.
2. The method of reducing dynamic surface tension according to claim 1 , characterized in that R 1 in Formula 1 is a 3,5,5-trimethylhexyl radical and R 2 is a methyl radical or hydrogen radical.
3. The method of reducing dynamic surface tension of claim 1 , wherein the composition further comprises one or more crop protection compositions in tank mixtures.
4. The method of reducing dynamic surface tension of claim 3 , wherein the composition further comprises one or more crop protection compositions in tank mixtures for application to grasses and cereals.
5. The method of reducing dynamic surface tension of claim 1 , wherein the composition further comprises herbicides, fungicides or insecticides.
