Appeal No. 2003-1914
Application No. 09/485,989
ii)- alkylamine alkoxylated with at least 5 alkoxy
moieties; and
iii)- block c-polymers [sic, copolymers] obtained by
copolymerisation of ethylene oxide and propylene oxide;
iv)- nonionic surfactants of the formula:
R2-Y-(C2H4O)z-H
wherein R2 is selected from the group consisting of
primary, secondary and branched chain alkyl and/or acyl
hydrocarbyl groups; primary, secondary and branched
chain alkenyl hydrocarbyl groups; and primary secondary
and branched chain alkyl- and alkenyl-substituted
phenolic hydrocarbyl groups; and wherein Y is O,-C(O)O,
and z is less than 9; and
v)- mixtures thereof;
wherein the total level of said nonionic alkoxylated surfactant
is less than 10% by weight of the composition.
The examiner relies upon the following references as
evidence of obviousness:
Billenstein et al. (EP '547) 0,043,547 Jan. 13, 1982
(European patent application)
Chang (EP '052) 0,309,052 Mar. 29, 1989
(European Patent application)
Appellants' claimed invention is directed to a clear fabric
softening composition comprising a softening compound, a
principal solvent having a ClogP of from 0.15 to 1.0, and a
nonionic alkoxylated surfactant selected from the recited group
of compounds. The nonionic alkoxylated surfactant is present in
an amount of less than 10% by weight of the composition.
