  • Publication number: 20200022934
    Abstract: Sprayable compositions comprising a pyrethroid, a viscosity building agent, an emulsifier or surfactant, and an emollient are provided. The compositions have a viscosity that allows for delivery of the spray from a pressurized container such that the pyrethroid is administered in a consistent amount that uniformly covers the body of a subject. This obviates the need to rub the composition into the skin. In preferred embodiments, the pyrethroid is permethrin; the viscosity building agent is selected from the group consisting of carbomers, xanthan gum, or a combination thereof; the emulsifier or surfactant is selected from the group consisting of glyceryl mononstearate, PEG40 hydrogenated castor oil, cholesterol, steareth-10, steareth-20, and combinations thereof; and the emollient is selected from the group consisting of C12-C15 alkyl benzoates, diisopropyl adipate, silicon oil, mineral oil, or any combination thereof.

  • Publication number: 20150220927
    Abstract: Techniques and mechanisms to provide indemnification for a transaction involving communications between networked devices. In an embodiment, attestation logic of a first device sends to a second device attestation information to indicate a trustworthiness level of first device. Based on the attestation information, indemnification logic of the second device determines an indemnification value representing a cost of an indemnification for a first transaction. Indemnification logic of the first device receives the indemnification value and determines, based on the indemnification value, whether a participation in the transaction is to take place.
