  • Cyclodextrin inclusion complex of piperonyl butoxide
    Patent number: 4524068
    Abstract: The invention relates to new inclusion complexes of piperonyl butoxide formed with cyclodextrin.The new complex of the invention can be prepared by reacting cyclodextrin or a solution thereof formed with water and/or an organic solvent having 1-4 carbon atoms, preferably ethanol with piperonyl butoxide or a solution thereof formed with an organic solvent having 1-4 carbon atoms, preferably ethanol at a temperature between 20.degree. C. and 90.degree. C., whereby the piperonyl butoxide is used in an amount of 0.6-1.5 moles related to 1 mole of cyclodextrin.The complexes of the present invention synergize the pesticidal effect of known insecticides and fungicides to a much higher extent of known insecticides and fungicides to a much higher extent than piperonyl butoxide used per se.
