  • Patent number: 8877681
    Abstract: The present invention relates to the use of specific amphiphilic alkoxyates as synergistic adjuvant for agrotechnical applications. Suitable agrotechnical compositions are also described. Thus, the addition of such alkoxylates makes possible an accelerated uptake of active ingredients by the plant. The alkoxylates to be used are alkoxylates based on branched alcohols such as 2-propylheptanol, C13-oxo alcohols and C10-oxo alcohols.
    Type: Grant
    Filed: February 3, 2012
    Date of Patent: November 4, 2014
    Assignee: BASF SE
