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 amine-containing surfactants and organic acids to lower the pH of various compounds and also keep them soluble in water.
Claims56
A composition comprising of:
- (a) a carboxylic acid or phosphorus containing acid providing that the phosphorus containing acid is not a glyphosate,
- (b) an amine containing surfactant and
- (c) at least one water soluble agricultural chemical,
- with the proviso that the composition contains less than 3 percent by weight of phosphate ester surfactant and the proviso that if a carboxylic acid and glyphosate are present, then said glyphosate and carboxylic acid are in a weight/weight ratio of glyphosate to carboxylic acid in a 8:1 to about 2:1.

A composition comprising:
- (a) a phosphorus containing acid providing that the phosphorus containing acid is not a glyphosate,
- (b) an amine containing surfactant and
- (c) at least one water soluble agricultural chemical,
- with the proviso that the composition contains less than 3 percent by weight of phosphate ester surfactant.
1 more element
A composition comprising:
- (a) a phosphorus containing acid providing that the phosphorus containing acid is not a glyphosate,
- (b) an amine containing surfactant of the formula:
- 8
- where x, y, a, b, c, d, r, and s are independently a number from 0-100, with the proviso that the sum of a+b+c+d+r+s+x+y must be at least 4 and
- (c) at least one water soluble agricultural chemical,
- with the proviso that the composition contains less than 3 percent by weight of phosphate ester surfactant.

A composition comprising of:
- (a) a carboxylic acid or phosphorus containing acid providing that the phosphorus containing acid is not a glyphosate,
- (b) an amine containing surfactant and
- (c) at least one water soluble agricultural chemical,
- with the proviso that the composition contains less than 3 percent by weight of phosphate ester surfactant and the proviso that if a carboxylic acid is used for said component (a) and a glyphosate is used for said component (c), then said carboxylic acid is present in an amount that does not effectively reduce eye irritation.
