Appeal No. 96-0937
Application 08/203,723
Advisory Action mailed November 30, 1994 (Paper No. 15). This leaves claims 1, 2, 4
through 6, 8, 11, 12, 14 through 16, 18 and 20 through 26 for our consideration.
Claim 1 is illustrative of the subject matter on appeal and reads as follows:
1. A hair care composition comprising:
(a) a hair styling/conditioning component comprising:
(i) from about 0.1% to about 10%, by weight of the composition, of a silicone
macromer-containing hair styling/conditioning copolymer, said silicone macromer,
molecular weight (weight average) of from about 1,000 to about 50,000, covalently
bonded to a nonsilicone organic polymer backbone or organic oligomeric portion of a
polymeric backbone, said copolymer having a molecular weight of from about 200,000
to about 1,000,000 and a Tg of at least about -20EC;
(ii) from about 0.1% to about 99.7%, by weight of the composition, of volatile
solvent in which said copolymer is soluble or dispersible, said volatile solvent being a
volatile silicone fluid which is immiscible in water, wherein said copolymer is solubilized
or dispersed in said volatile silicone fluid to provide a copolymer-volatile solvent
solution, and wherein, when said solution is dried, the copolymer separates into a
discontinuous phase which includes the silicone macromer and a continuous phase
which includes the nonsilicone organic polymer backbone or organic oligomeric portion;
and
(iii) a nonvolatile plasticizer that is safe for topical application to the hair and skin
of humans, wherein said composition has a plasticizer:copolymer weight ratio of from
about 1:20 to about 1:1 and said plasticizer is miscible with said copolymer-volatile
solvent solution and has a solubility parameter, *, of between about 7 and about 10
½
(calories/cc) ; and
(b) from about 65% to about 99.7% of an additional carrier vehicle which is water.
