Appeal No. 1998-0654
Application No. 08/522,874
1. Shampoo compositions comprising:
(A) from about 0.5% to about 50% by weight of synthetic
surfactant;
(B) from about 0.05% to about 25% by weight of dispersed
water insoluble polymer latex particles having a glass
transition temperature of from about -20EC to about 10EC;
and
(C) water.
The examiner relies upon the following references as
evidence of obviousness:

Appellants' claimed invention is directed to a water-
based shampoo comprising a surfactant and dispersed water
insoluble polymer latex particles of the recited glass
transition temperature. According to appellants, they "have
found that styling shampoos provide improved styling polymer
deposition and performance by using dispersed latex styling
polymer particles, provided that the styling polymers are
dispersed rather than solubilized in the shampoo matrix and
provided that they have a selectively low Tg value as
described above" (sentence bridging pages 3 and 4 of principal
brief).
