linear silicone polyether, an ",T-diene crosslinked silicone elastomer, and a nonionic
organic emulsifier. The W/O emulsion is free of silicone elastomers prepared using
unsaturated compounds containing silicon atoms." [Specification, ¶ 7.]
2. Claim 7 is illustrative and reads (paragraphing added):
A composition comprising a water-in-oil (W/O) emulsion having a
discontinuous aqueous phase dispersed in a continuous oil phase,
the continuous oil phase of the W/O emulsion comprising
a linear silicone polyether,
the linear silicone polyether having a rake type structure
wherein the polyoxyethylene or polyoxyethylene-
polyoxypropylene copolymeric units are grafted onto a
siloxane backbone, or
the linear silicone polyether having an ABA block
copolymeric structure wherein A represents the polyether
portion and B represents the siloxane portion of an ABA
structure;
a non-emulsifying ",T-diene crosslinked silicone elastomer having
no oxyalkylene units in its structure; and
a nonionic organic emulsifier selected from the group consisting of
carboxylated alcohol ethoxylates, carboxylated alkylphenol
ethoxylates, ethoxylated alcohols, ethoxylated fatty acids,
ethoxylated fatty esters, ethoxylated fatty oils, glycerol esters,
polyglycerol fatty esters, ethoxylated glycerol esters, sorbitan
derivatives, sucrose esters and their derivatives, and glucose
esters and their derivatives;
the W/O emulsion being free of silicone elastomers prepared using
unsaturated compounds containing silicon atoms.
3. According to the specification (¶ 22),
...the term ",T-diene crosslinked silicone elastomer is intended to mean
",T-diene crosslinked silicone elastomers having no oxyalkylene units in
their structure. They have been referred to generally in the art as non-
