Application No. 11/050,224
For the purpose of deciding grouping 1), we have selected claim 1 as
representative. 37 C.F.R. § 41.37(c)(1)(vii). It reads as follows:
1. A solid particulate laundry detergent composition comprising:
(a) from about 2wt% to about 20wt% clay;
(b) from about 0.5wt% to about 10wt% polydimethylsiloxane;
(c) from about 0.1wt% to about 5wt% flocculating component;
(d) from about 5wt% to about 25wt% anionic detersive surfactant;
(e) from about lwt% to about 22wt% zeolite;
(f) from about 12wt% to about 30wt% carbonate; and
wherein the polydimethylsiloxane is in a pre-emulsified form and
wherein the clay and polydimethylsiloxane are present together in the
composition in the form of a co-particulate admixture.
Separately argued claims 10, 11, 17, 24, and 25 depend on claim 1. They
read as follows:
10. A composition according to Claim 1, wherein the anionic detersive
surfactant comprises: (a) a linear or branched, substituted or unsubstituted, C10-13
alkyl benzene sulphonate; and (b) a linear or branched, substituted or
unsubstituted, C8-18 alkyl sulphate, and wherein the weight ratio of the alkyl
benzene sulphonate (a) to the alkyl sulphate (b) is greater than about 5: 1.
11. A composition according to Claim 1, wherein the composition comprises
from about 0.1wt% to about 5wt% polymeric polycarboxylate.
17. A composition according to Claim 1, wherein the polydimethylsiloxane
has a viscosity of from about 50,000cP to about 400,000cP, when measured at a
shear rate of 20s-1 and a temperature of 20°C.
24. The composition according to Claim 1, wherein the pre-emulsion form
has a viscosity of from 1,500cP to 50,000cP.
25. A composition according to Claim 1, wherein the pre-emulsion form has
a volume average primary droplet size of from 0.1 micrometers to 5,000
micrometers.
