Abstract
An ectoparasiticidal composition is provided that comprises a mixture of a carrier and an active with an emulsifying agent. The carrier comprises non-volatile low viscosity siloxane and the active comprises a non-volatile high viscosity siloxane. The low viscosity siloxane and the high viscosity siloxane both have a closed cup flash point of at least 100° C. Preferably, both the low viscosity siloxane and the high viscosity siloxane comprise a dimeticone or a dimeticonol or a mixture of same, the the low viscosity siloxane having a viscosity in the range of 5 to 1000 centistokes inclusive and the high viscosity siloxane having a viscosity of at least 1000 centistokes.
