Abstract

Abstract Dilute dispersions of cationic fabric conditioners in water undergo creaming in the presence of dissolved electrolyte to form concentrated, readily dispersible creams having a spherulitic structure and typically containing from 8 to 50% by weight of fabric conditioner and 1 to 15% by weight of electrolyte.

Claims Analysis

Total Claims: 22
Claim 1
Independent Claim 61 words
A composition comprising: water; at least one cationic fabric conditioner having two C₁₅₋₂₂ alkyl and/or alkenyl groups, dispersed in the water; and dissolved electrolyte in a concentration sufficient (i) to form said fabric conditioner into an optically anisotropic spherulitic composition, and/or (ii) to cause creaming if it were present at said concentration in a more dilute dispersion of said fabric conditioner.
Claim 2
Dependent Claim 61 words
A composition comprising: water; at least one cationic fabric conditioner having two C₁₅₋₂₂ alkyl and/or alkenyl groups, dispersed in the water; and dissolved electrolyte in a concentration sufficient (i) to form said fabric conditioner into an optically anisotropic spherulitic composition, and/or (ii) to cause creaming if it were present at said concentration in a more dilute dispersion of said fabric conditioner.
Claim 3
Dependent Claim 42 words
A composition formed by dispersing at least one cationic fabric conditioner having two C₁₅₋₂₂ alkyl and/or alkenyl groups in water in the presence of sufficient electrolyte to cause creaming thereof, and separating the cream so formed from the rest of the liquid.
Claim 4
Dependent Claim 42 words
A composition formed by dispersing at least one cationic fabric conditioner having two C₁₅₋₂₂ alkyl and/or alkenyl groups in water in the presence of sufficient electrolyte to cause creaming thereof, and separating the cream so formed from the rest of the liquid.
Claim 5
Dependent Claim 15 words
A composition according to claim 2 wherein said separation is effected by centrifuging the dispersion.
Claim 6
Dependent Claim 56 words
A composition comprising: water; electrolyte dissolved in said water in a concentration greater than 1% by weight of said composition; and a cationic fabric conditioner comprising at least 40% by weight, based on the total active weight, of an amidoamine derivative having two C₁₅₋₂₂ alkyl and/or alkenyl groups, dispersed in the water as optically anisotropic spherulites.
Claim 7
Dependent Claim 56 words
A composition comprising: water; electrolyte dissolved in said water in a concentration greater than 1% by weight of said composition; and a cationic fabric conditioner comprising at least 40% by weight, based on the total active weight, of an amidoamine derivative having two C₁₅₋₂₂ alkyl and/or alkenyl groups, dispersed in the water as optically anisotropic spherulites.
Claim 8
Dependent Claim 43 words
A composition according to any foregoing claim wherein said fabric conditioner comprises at least 40% by weight of an amidoamine derivative, based on the total active weight, and is present in a concentration of from 18 to 50% by weight of said composition.
Claim 9
Dependent Claim 23 words
A composition according to claim 5 wherein the concentration of said fabric conditioner is from 20 to 40% by weight of said composition.
Claim 10
Dependent Claim 25 words
A compostion according to claim 6 wherein said fabric conditioner is present in a concentration of from 25 to 35% by weight of said composition.
Claim 11
Dependent Claim 45 words
A composition according to any foregoing claim wherein said fabric conditioner comprises at least 40% by weight of an amidoamine derivative, based on the total active weight, and said electrolyte is present in a concentration of from 3 to 15% by weight of the composition.
Claim 12
Dependent Claim 24 words
A composition according to claim 8 wherein said electrolyte is present in a concentration of from 5 to 12% by weight of said composition.
Claim 13
Independent Claim 39 words
A method of preparing a creamed fabric conditioner which comprises forming a dispersion of a cationic fabric conditioner in water in the presence of sufficient electrolyte to effect creaming of the fabric conditioner, and separating the cream so formed.
Claim 14
Independent Claim 39 words
A method of preparing a creamed fabric conditioner which comprises forming a dispersion of a cationic fabric conditioner in water in the presence of sufficient electrolyte to effect creaming of the fabric conditioner, and separating the cream so formed.
Claim 15
Dependent Claim 43 words
A method according to claim 10 wherein said dispersion initally contains from 2 to 18% by weight, based on the total weight of the dispersion of a fabric conditioner comprising at least 40%, based on the total active weight, of an amidoamine derivative.
Claim 16
Dependent Claim 24 words
A method according to claim 11 wherein the electrolyte is present in a concentration of from 3 to 15% by weight of said dispersion.
Claim 17
Independent Claim 17 words
A method according to any of claims 10 to 12 wherein said separation is effected by centrifuging.
Claim 18
Independent Claim 75 words
A method of preparing a concentrated fabric conditioner which comprises mixing together: a cationic fabric conditioner comprising at least 40%, based on the total active weight, of an amidoamine derivative; water; and electrolyte; in proportions adapted to provided a concentration of from 18 to 50% by weight, based on the total weight of the composition, of said fabric conditioner and from 1 to 15% based on the total weight of the composition of said electrolyte.
Claim 19
Independent Claim 75 words
A method of preparing a concentrated fabric conditioner which comprises mixing together: a cationic fabric conditioner comprising at least 40%, based on the total active weight, of an amidoamine derivative; water; and electrolyte; in proportions adapted to provided a concentration of from 18 to 50% by weight, based on the total weight of the composition, of said fabric conditioner and from 1 to 15% based on the total weight of the composition of said electrolyte.
Claim 20
Dependent Claim 50 words

Claim 21
Dependent Claim 16 words
A composition according to claim 14 containing from 5 to 30% by weight of a builder.
Claim 22
Dependent Claim 22 words
A composition according to any of claims 1 to 10 substantially as described herein with reference to any one of the examples.
