Abstract
Abstract A fabric conditioning composition comprises a fabric conditioning agent including a cationic fabric softening material, together with an inorganic material capable of precipitating a metal hydroxide or hydrated oxide at a pH of about 7.5 of less in water. The latter material is preferably aluminum chlorhydrate. A typical composition contains about 4% quaternary ammonium cationic fabric softener and from 0.5% to 1.5% aluminum chlorhydrate. The compositions are useful as rinse products and give improved fabric softness in the presence of anionic carry-over from the wash.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
87 words
A fabric conditioning composition in liquid form comprising from about 0.5% to about 60% by weight of a fabric conditioning agent which includes at least one cationic fabric softening material, characterized in that the composition further comprises from about 0.1% to about 8% by weight of an inorganic polymeric material capable of precipitating a metal hydroxide or hydrated oxide at a pH of about 7.5 or less in water, the weight ratio of the fabric conditioning agent to the inorganic polymeric material being at least about 1.5:1.
Claim 2
Dependent Claim
87 words
A fabric conditioning composition in liquid form comprising from about 0.5% to about 60% by weight of a fabric conditioning agent which includes at least one cationic fabric softening material, characterized in that the composition further comprises from about 0.1% to about 8% by weight of an inorganic polymeric material capable of precipitating a metal hydroxide or hydrated oxide at a pH of about 7.5 or less in water, the weight ratio of the fabric conditioning agent to the inorganic polymeric material being at least about 1.5:1.
Claim 3
Dependent Claim
28 words
A fabric conditioning composition according to claim 1, characterised in that the inorganic polymeric material has critical coagulation concentration (as hereinbefore defined) of at least about 0.1 M.
Claim 4
Dependent Claim
29 words
A fabric conditioning composition according to claim 1, characterised in that the inorganic polymeric material has a critical coagulation concentration (as herebefore defined) of at least about 0.2 M.
Claim 5
Dependent Claim
27 words
A fabric conditioning composition according to claim 1, characterised in that the inorganic polymeric material is selected from compounds of aluminium, titanium and zirconium, and mixtures thereof.
Claim 6
Dependent Claim
31 words
A fabric conditioning composition according to claim 1, characterised in that the weight ratio of the fabric conditioning agent to the inorganic polymeric material is between about 4:1 and about 20:1.
Claim 7
Dependent Claim
43 words
A fabric conditioning composition according to claim 1, characterized in that the fabric conditioning agent comprises a mixture of at least one cationic fabric softening material with at least one nonionic fabric softening material in a weight ratio of at least about 1:1.
Claim 8
Dependent Claim
62 words
A fabric conditioning composition according to claim 1, in liquid form, characterised by containing an aqueous base, from about 0.5% to about 30% by weight of the fabric conditioning agent and from about 0.1% to about 2.5% by weight of the inorganic polymeric material, the weight ratio of the fabric conditioning agent to the inorganic polymeric material being less than about 40:1.
Claim 9
Dependent Claim
59 words
A fabric conditioning composition according to claim 1, in liquid form, characterised by containing an aqueous base, from about 10% to about 60% by weight of the fabric conditioning agent and sufficient of the inorganic polymeric material to yield a weight ratio of the fabric conditioning agent to the inorganic polymeric material of between about 3:1 and about 80:1.
Claim 10
Dependent Claim
21 words
A fabric conditioning composition according to claim 7 or 8, characterised by having a pH between about 4.0 and about 6.0.
Claim 11
Dependent Claim
