Appeal No. 95-0415
Application 08/013,877
smoother coating on the skin after application of the composition
to the skin. See page 2 of the specification.
DISCUSSION
Claims 2-8 are separately argued as being patentably
distinct from the remaining claims. Thus, we will focus the
discussion on claims 1 and 2.
Cobb and Bolich each teach compositions which contain
combinations of volatile silicone fluids and silicone gums.
Clement teaches a composition which is topically applied to the
skin and contains volatile silicone carriers and silicone gums in
concentrations that fall within the ranges of claim 1.
Both Cobb and Bolich disclose the use of silicone fluids in
the disclosed compositions which are linear polydimethyl
siloxanes. The first embodiment of the alkylmethylsiloxane
ingredient of claim 1 herein is a genus of compounds which also
are linear polymeric siloxanes. They differ from the linear
compounds disclosed by both Cobb and Bolich by requiring at least
an ethyl group on the repeated silicone moiety.
It is reasonable to conclude that the close structurally
related ethyl and propyl homologs of the specifically disclosed
linear siloxane would possess similar physical properties and
