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.
