Appeal No. 1997-3389
Application No. 08/449,956
The present claims, like those in the related
applications, are directed to a laundry detergent composition
which includes, inter alia, a nonionic ethoxylated alcohol
surfactant and an anionic ethoxylated alcohol sulfate salt as
a second surfactant.
Appellants stipulate on page 5 of their Brief that the
appealed claims stand or fall together. Accordingly, we will
limit our consideration to claim 1, the sole independent
claim, which reads as follows:
1. A powder laundry detergent composition with improved cold
water residue properties, which is a granulated blend of
ingredients comprising (1) between about 40-90 weight percent
of a water-soluble detergent builder ingredient wherein at
least 72 weight percent of the detergent builder ingredient is
sodium carbonate; and (2) between about 5-40 weight percent of
a detergent active ingredient which is a surfactant blend
comprising (a) between about 40-80 weight percent, based on
the surfactant weight, of an anionic salt compound
corresponding to the formula:
R-O-(CH CH O) -SO M
2 2 n 3
where R is a C -C alkyl group, n is an average number of
10 15
ethoxylate groups between about 1-9, and M is an alkali metal
or ammonium cation, and (b) between about 20-60 weight
percent, based on surfactant weight, of a nonionic compound
corresponding to the formula:
R-O-(CH CH O) -H
2 2 n
