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.
Claims16
A water soluble surfactant composition comprising
- (a) an amine surfactant component having the chemical structure ##STR8## wherein x is a number from about 7 to about 19;
- n.sub.1 and n.sub.2 are numbers independently selected from 1 to about 30;
- the average sum of n.sub.1 and n.sub.2 is 2 or greater;
- and R.sub.1 and R.sub.2 are C.sub.2 -C.sub.4 alkylene radicals;
- said amine surfactant component being in an amount sufficient to cause unacceptable eye irritation during spraying of the composition;
- and
- (b) an effective eye irritation reducing amount of sulfated polyoxyalkylene alkylphenol surfactant component, optionally containing of 3% by weight or more of a ring sulfonated component, and having the chemical structure ##STR9## wherein m is a number up to about 60, R is C.sub.2 -C.sub.4 alkylene and R.sup.1 is a C.sub.8 -C.sub.20 alkyl group and being present in an amount sufficient to reduce the eye irritation.
A water soluble surfactant composition comprising
- (a) an amine surfactant component comprising an alkylamine having the chemical structure ##STR10## wherein x is a number from about 7 to about 19;
- n, and n.sub.2 are numbers independently selected from 1 to about 30;
- the average sum of n.sub.1 and n.sub.2 is 2 or greater;
- and R.sub.1 and R.sub.2 are C.sub.2 -C.sub.4 alkylene radicals;
- said amine surfactant component being in an amount sufficient to cause unacceptable eye irritation during spraying of the composition;
- and
- (b) an effective eye irritation reducing amount of a sulfated alcohol component having the chemical structure
- R.sub.3 --O--(R.sub.4 O)m--SO.sub.3
- wherein R.sub.3 is C.sub.8 -C.sub.20 alkyl, R.sub.4 is a C.sub.2 -C.sub.4 alkylene radical and m is a number 0 to 60 and being present in an amount sufficient to reduce the eye irritation.
A water soluble surfactant composition comprising:
- (a) an amine surfactant component having the chemical structure ##STR11## wherein x is a number from about 7 to about 19;
- n.sub.1 and n.sub.2 are numbers independently selected from 1 to about 30;
- the average sum of n.sub.1 and n.sub.2 is 2 or greater;
- R.sub.1 and R.sub.2 are C.sub.2 -C.sub.4 alkylene radicals, said amine surfactant component being in an amount sufficient to cause unacceptable eye irritation during spraying of the composition;
- and
- (b) an effective eye irritation reducing amount of a phosphate monoester or mixture of phosphate monoesters having the general formula ##STR12## wherein R.sup.1 is C.sub.8 -C.sub.20 alkyl or C.sub.8 -C.sub.20 alkylphenyl;
- R is C.sub.2 -C.sub.4 alkylene;
- m is zero or a number up to about 60;
- alone or in combination with a phosphate diester or mixture of phosphate diesters having the general formula:
- ##STR13## wherein R, R.sub.1, and m are as just described, provided the weight percentage of phosphate monoester (or monoesters) exceeds that of the phosphate diester (or diesters).
