  • Patent number: 8747875
    Abstract: An insecticidal composition comprising stabilized pyrethrins or pyrethroids is provided. Such composition includes stabilizing effective amount of N,N-dialkyl fatty acid amide solvents and certain ultraviolet-light absorbers. In such composition, the pyrethrins or pyrethroid can retain their insecticidal activity for an acceptably long period of time. Therefore, an advantage of this invention is to provide a topical pyrethrins or pyrethroid based insecticide which can remain effective in light over a long time period. Another advantage of this invention is to provide a stabilized topical pyrethrins or pyrethroid insecticide insecticidal formulation containing a high concentration of the active pyrethrins or pyrethroid ingredient to minimize the volume of formulation required.

  • Patent number: 5909753
    Abstract: A dispenser is provided for separately storing and facilitating the mixture of separate components of a two-part composition. The dispenser includes a first container having a chamber for retaining one of the components and a second container having a chamber for retaining the other of the components and for mixing the components together to form the resultant two-part composition. A receptacle sleeve is provided and is mounted on the second container. The receptacle sleeve is adapted to secure the two containers together during periods of storage and transportation as well as to facilitate mixture of the components. The receptacle sleeve further serves to protect the user from exposure to the unmixed components as well as providing a drip-free spout in dispensing the composition. A method is further provided for alternately storing the separate components and admixing them together in one of the containers.
