Abstract
The invention pertains to new composition and a method for increasing the solubility of various agricultural compounds in water at a low pH. The compounds included in this patent are typically not soluble at pH ranges less than 7 to produce commercially viable liquid concentrates. This method requires the use of tallowamine ethoxylates and phosphate esters to lower the pH of various compounds and also keep them soluble in water.
Claims26
A composition which consists essentially of:
- (a) at least one acid ester surfactant of the formula (I) or (II) ##STR15## where R.sup.1 is H or and alkyl or alkylaryl group R.sup.2 is H, alkyl or alkylaryl group,
- M is hydrogen, sodium or ammonium counterion,
- x, y, z, a, b and c are identical or different and are a number from 0 to 100, with the proviso that x+y+z+a+b+c is at least 2,
- (b) at least one amine containing surfactant and
- (c) at least one water soluble agricultural chemical.

A composition consisting essentially of:
- (a) at least one acid ester surfactant of the formula (I) or (II) ##STR18## where R.sup.1 is --H or an alkyl or alkylaryl group,
- R.sup.2 is --H or an alkyl or alkyl aryl group,
- M is hydrogen, sodium or ammonium counterion,
- x, y, z, a, b and c are identical or different and are a number from 0 to 100, with the proviso that the sum of x+y+z+a+b+c is at least 2,
