Abstract
Abstract An aqueous fabric softening composition containing less than 10% cationic softener also includes an alkoxylated fatty amine having up to 7 alkylene oxide groups per molecule, such as ethoxylated tallow amine at exemplified levels of 4.0 to 12.0%. The alkoxylated compound enhances the softening and anti-static properties of the composition.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
84 words
An aqueous fabric softening composition comprising: (i) an aqueous base; (ii) at least 1% to less than 10% by weight of a water-insoluble cationic fabric softener; and (iii) a nonionic material which comprises an alkylene oxide adduct of a fatty amine, the fatty amine containing at least 10 carbon atoms and the adduct containing an average of not more than 7 alkylene oxide groups per molecule, the total level of the cationic fabric softener and the nonionic material being at least 12% by weight.
Claim 2
Dependent Claim
84 words
An aqueous fabric softening composition comprising: (i) an aqueous base; (ii) at least 1% to less than 10% by weight of a water-insoluble cationic fabric softener; and (iii) a nonionic material which comprises an alkylene oxide adduct of a fatty amine, the fatty amine containing at least 10 carbon atoms and the adduct containing an average of not more than 7 alkylene oxide groups per molecule, the total level of the cationic fabric softener and the nonionic material being at least 12% by weight.
Claim 3
Dependent Claim
27 words
An aqueous fabric softening composition according to claim 1, wherein the level of said water-insoluble cationic fabric softener is more than 6% by weight of the composition.
Claim 4
Dependent Claim
25 words
An aqueous fabric softening composition according to claim 1, wherein the level of said nonionic material is less than 10% by weight of the composition.
Claim 5
Dependent Claim
26 words
An aqueous fabric softening composition according to claim 1, wherein the weight ratio of said cationic fabric softener to said nonionic material is at least 1:1.
Claim 6
Dependent Claim
25 words
An aqueous fabric softening composition according to claim 1, further comprising an electrolyte selected from ionic salts of lithium, magnesium, calcium, aluminium and mixtures thereof.
Claim 7
Dependent Claim
39 words
A process for preparing an aqueous fabric softening composition according to claim 1, the process comprising the step of dispersing a molten mixture of the cationic softener and the nonionic material in water with stirring to form a dispersion.
