  • Use of a quaternary ammonium glycoside surfactant as an adjuvant for fertilizers or pesticides
    Patent number: 6881706
    Abstract: The present invention relates to the use of a quaternary ammonium glycoside surfactant as an adjuvant for fertilizers or pesticides, such as herbicides. The surfactant contains at least one hydrocarbon group with 6-24 carbon atoms and at least one quaternary ammonium group where at least one substituent is an alkyleneoxy containing group which is connected to a saccharide residue by a glycosidic bond. Also compositions containing pesticides or fertilizers are described. These quaternary ammonium glycoside surfactants have an essentially improved biodegradability. They also improve the uptake and efficacy of fertilizers and herbicides.

  • Use of amine compounds with improved biodegradability as adjuvants for pesticides and fertilizers
    Patent number: 6747164
    Abstract: The present invention relates to the use of an amino compound, which is an esteramine or an amidoamine surfactant with improved biodegradability, as an adjuvant for agrochemically active compounds such as pesticides or fertilizers. The adjuvant has Formula (I) where R1 is an aliphatic group containing 7-22 carbon atoms; EO is an ethyleneoxy group; Y is 0 or NH; R2 and R3 is independently CH2CH2OH or an alkyl group with 1-5 carbon atoms, preferably 1-3 carbon atoms; n is a number between 0-10; x is a number 0-1 provided that when Y is O, then x is 1, and when Y is NH, then x is O; and m is a number 2-6, preferably 2-3, provided that when Y is NH, then m is 3-6, preferably 3; or an adduct obtained by reacting one mole of the compound with 1-5 moles of an alkylene oxide having 2-3 carbon atoms.

  • Cationic sugar surfactants from ethoxylated ammonium compounds and reducing saccharides
    Patent number: 6503880
    Abstract: The present invention relates to cationic sugar surfactants with improved biodegradability that can be used as hydrotropes for surfactants, especially for nonionic alkylene oxide adducts in alkaline solutions, and as cleaners for hard surfaces. The cationic sugar surfactants contain at least one hydrocarbon group with 6-24 carbon atoms and at least one quaternary ammonium group where at least one substituent is an alkyleneoxy containing group which is connected to a saccharide residue by a glycosidic bond. They are obtained from ethoxylated quaternary ammounium compounds and reducing saccharides or alkyl glycosides.
