I bought some Nix (permethrin) Cream Rinse with 1% Permethrin. How long do I need to keep it on my skin to treat scabies? Or is it strong enough to kill them?

Scabies treamtment. the recommended treat for scabies is 5% pernethrin in a cream form for 12hour, The cream rinse would not be enough, also worry about exposure to the solvant . I will not use it, also make sure diagnosis is correct .
