Pesticidal compositions of polyoxyalkylene alkylamine surfactants having reduced eye irritation
First Claim
1. An aqueous or water soluble composition comprising(a) a glyphosate herbicide in a herbicidally effective amount;
- (b) an amine surfactant component having the chemical structure ##STR8## wherein x is a number from about 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;
said amine surfactant component being in an amount sufficient to potentiate the glyphosate herbicidal activity; and
(c) an acidic compound having the chemical structure
space="preserve" listing-type="equation">R.sub.3 --O--(R.sub.4 O)m--X.sub.1wherein R3 is C8 -C20 alkyl or C8 -C20 alkylphenyl, R4 is C2 -C4 alkylene, m is a number from 0 to about 60, and X1 is selected from the group consisting of carboxylate, sulfate and phosphate;
said acidic compound being present in an amount sufficient to reduce the eye irritancy of the composition caused by component (b).

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, mono-or di-(polyoxyalkylene alkylphenol) 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.
