have included any two volatile carriers or obvious variants
thereof in a composition of the prior art in light of this

To the extent that the compositions of Cobb and Bolich are
taught to be used as shampoos and conditioners (see the examples
of both references) the methods of claims 13 and 14 would have

invention, have reasonably expected structurally similar
