Herbicidal compositions of polyoxyalkylene alkylamine surfactants having reduced eye irritation
First Claim
1. An aqueous concentrate herbicidal composition comprising(a) about 5% to about 50% by weight of a water soluble salt of glyphosate;
- (b) an amine surfactant component consisting of (i) one or more compounds having the chemical structure ##STR8## wherein x is a number from 7 to about 19, n1 and n2 are numbers independently selected from 1 to about 30, the average sum of n1 and n2 is 2 or greater, and R1 and R2 are C2 -C4 alkylene radicals; and
(ii) one or more glycols selected from ethylene glycol, propylene glycol, polyethylene glycol and polypropylene glycol in an amount of zero to about 30% by weight of the amine surfactant component;
said amine surfactant component being in an amount sufficient to cause unacceptable eye irritation;
(c) an effective eye irritation reducing amount of a phosphate surfactant component consisting of a phosphate monoester or mixture of phosphate monoesters having the chemical structure ##STR9## where R7 is C8 -C20 alkyl or C8 -C20 alkylphenyl, R is C2 -C4 alkylene, and m is a number from zero to about 60;
alone or in combination with a phosphate diester or mixture of phosphate diesters having the chemical structure ##STR10## where R7, R and m are as defined immediately above; and
(d) water in an amount sufficient to provide a stable aqueous solution of the salt of glyphosate in presence of the amine and phosphate surfactant components.

Abstract
There are provided compositions of certain polyoxyalkylene alkylamine surfactants having eye irritation reduced by the addition of an effective amount of a sulfated polyoxyalkylene alkylphenol alcohol sulfate, polyoxyalkylene alcohol sulfate, mono- or dialcohol phosphate mono- or di-(polyoxyalkylene alcohol) phosphate, polyoxyalkylene alkylphenol carboxylate or polyoxyalkylene alcohol carboxylate surfactant. Also provided are pesticidal, particularly herbicidal, compositions comprising polyoxyalkylene alkylamine surfactants having eye irritation reduced by addition of these eye irritation reducing compounds.
