Aqueous adjuvant concentrates with improved spray drift properties

摘要

Aqueous adjuvant concentrate with improved spray drift properties and method for its preparation comprising the steps of: i) dissolving from 15 to 30% by weight, on the weight of the final concentrate, of ammonium sulfate in water; ii) adding to the solution from 1 to 10% by weight, on the weight of the final concentrate, of anionic esters of alkyl polyglycosides; iii) dispersing in the solution from 2 to 10% by weight, on the weight of the final concentrate, of hydroxypropyl guar or hydroxypropyl guar acetate; iiii) adding ammonium sulfate to the dispersion to reach an ammonium sulfate final concentration comprised between 33 and 40% by weight.

主权项

1. An aqueous adjuvant concentrate comprising from about 33 to about 40% by weight of ammonium sulfate, from about 1 to about 10% by weight of anionic esters of alkyl polyglycosides and from about 2 to about 10% by weight of hydroxypropyl guar or hydroxypropyl guar acetate;
wherein the aqueous adjuvant concentrate is pourable, does not include a suspending aid or water soluble organic solvent, and the hydroxypropyl guar or hydroxypropyl guar acetate is in dispersed form.
