BACKGROUND
The Appellants’ invention relates to a self-thickened aqueous cleaning composition and process
of making. Claim 1 is representative of the subject matter on appeal and is reproduced below:
1. A self-thickened aqueous cleaning composition having a viscosity of from 50 to 700 cps at
60 rpm shear rate at 20EC, comprising from 1% to 25% by weight of the total composition of an alkyl
sulphate anionic surfactant derived from natural coconut oil, from 0.1% to 8% by weight of the total
composition of ammonium salts and from 0.5% to 25% by weight of the total composition of a
compound of the structure :
R -O [(R O) n (R O)m] R , wherein :1 2 3 4
- R is a C alkyl or alkenyl group;1 1-25
- R is a C aliphatic hydrocarbon chain;2 2-4
- R is a methyl or ethyl monosubstituted C -C aliphatic hydrocarbon chain;3 2 4
- R is a C alkyl or alkenyl or carboxyl chain, or H;4 1-25
- n is an integer of from 1 to 10;
- m is an integer of from 0 to 20;
or mixtures thereof.
