Appeal No. 1997-3350
Application No. 08/522,164
Similar claims are under appeal in related applications
08/436,182 (Appeal No. 97-3332) and 08/449,956 (Appeal No. 97-
3389).
The instant 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. In addition, the present claims call for
the inclusion of a polyethylene glycol (PEG). Claim 1 is
representative:
1. A powder laundry detergent composition with improved cold
water residue properties, which is a granulated blend of
ingredients consisting essentially of (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, (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
where R is a C -C alkyl group, and n is an average number of
10 15
ethoxylate groups between about 1-9; and (c) between about 5-
