  • Patent number: 5683958
    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.

  • Patent number: 5668085
    Abstract: Aqueous concentrates containing glyphosate herbicide which on dilution give spray solutions having higher herbicidal unit activity than prior art solutions comprise:(a) solubilized glyphosate equivalent to at least 40 grams per liter of glyphosate acid;(b) a surfactant which is (i) an amine having the formula ##STR1## where R represents a straight- or branched-chain alkyl or alkenyl group having from about 8 to about 22 carbon atoms, A represents an alkylene group, for example an ethylene or propylene group, and n and n' are integers such that n+n' has a value of from about 2 to about 8, (ii) a mixture of such amines having different groups R, the average number of carbon atoms in the groups R being from about 8 to about 22, or (iii) a mixture of such amines having different values of n and n', n and n' being integers such that in the mixture the average value of n+n' is from about 2 to about 8, R having a single value or an average value as in a mixture (ii);and optionally (c) an agriculturally acceptable in

  • Patent number: 5652197
    Abstract: The composition of the invention comprises a glyphosate herbicide and a quaternary ammonium compound the latter having the formula ##STR1## wherein --EO-- means an ethylene oxide radical and --PO-- means a propylene oxide radical, R.sup.1 and R.sup.2 are each independently an alkyl group having from 1 to 3 carbon atoms; R.sup.3 is an alkyl group having from 1 to 3 carbon atoms, a group having the formula (EO).sub.m --H or a group having the formula EO--(PO).sub.m --H; n (in a compound in which R.sup.3 is an alkyl group) or n+m (in a compound in which R.sup.3 is a group having the formula EO--(PO).sub.m --H), has a value of from about 2 to about 20; and X.sup.- is a suitable anion.
