Abstract
Abstract Liquid detergent compositions having improved softening and detergency properties comprising an alkyl glycoside, as the sole softening agent, a nonionic surfactant and an anionic surfactant as the three essential ingredients; and a method of simultaneously cleaning and softening without reducing brightener and detergency performance, which comprises treating fabrics with said composition in the wash cycle of the laundering operation.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
86 words
A method of simultaneously cleansing and softening fabrics without reducing brightener and detergency performance which comprises treating fabrics with an aqueous liquid detergent composition consisting essentially of about 6 to 30% by weight of a C 8 -C 23 alkyl mono- or polyglycoside as the sole softening agent in a nonionic-anionic surfactant system consisting of a major amount of about 15-30% by weight of a nonionic surfactant and a lesser amount of about 4-12% of an anionic surfactant, in the wash cycle of the laundering operation.
Claim 2
Independent Claim
86 words
A method of simultaneously cleansing and softening fabrics without reducing brightener and detergency performance which comprises treating fabrics with an aqueous liquid detergent composition consisting essentially of about 6 to 30% by weight of a C 8 -C 23 alkyl mono- or polyglycoside as the sole softening agent in a nonionic-anionic surfactant system consisting of a major amount of about 15-30% by weight of a nonionic surfactant and a lesser amount of about 4-12% of an anionic surfactant, in the wash cycle of the laundering operation.
Claim 3
Dependent Claim
13 words
The method according to claim 1 wherein said composition also contains a brightener.
Claim 4
Dependent Claim
16 words
The method according to claim 1, wherein the glycoside is C 12 -C 13 alkyl glycoside.
Claim 5
Dependent Claim
16 words
The method according to claim 1, wherein the glycoside is C 12 -C 13 alkyl triglycoside.
Claim 6
Dependent Claim
35 words
The method according to claim 1 wherein the alkyl mono- or polyglycoside has a saturated or unsaturated, branched or straight chain alkyl group and a hydrophilic glycoside group containing 1 to 10 reducing saccharide radicals.
Claim 7
Dependent Claim
34 words
The method according to claim 1, wherein the nonionic surfactant is selected from the group consisting of primary aliphatic alcohol ethoxylates, secondary aliphatic alcohol ethoxylates, alkylphenol ethoxylates, alcohol ethylene-oxide-propylene oxide condensates and mixtures thereof.
Claim 8
Dependent Claim
26 words
The method according to claim 7, wherein the nonionic surfactant is a C 12 -C 15 aliphatic alcohol having 7 ethylene-oxy groups per mole of alcohol.
Claim 9
Dependent Claim
27 words
The method according to claim 1, wherein the anionic surfactant is selected from the group consisting of alkyl benzene sulfonates, alcohol ether sulfates and ethoxylated alcohol sulfates.
Claim 10
Dependent Claim
15 words
The method according to claim 9, wherein the anionic surfactant is sodium dodecyl benzene sulfonate.
Claim 11
Dependent Claim
22 words
The method according to claim 1, wherein the anionic surfactant content is less than 50% by weight of the nonionic surfactant content.
Claim 12
Independent Claim
82 words
A method of simultaneously cleansing and softening fabrics without reducing brightener and detergency performance which comprises treating fabrics with an aqueous liquid detergent composition consisting essentially of about 6 to 30% by weight of a methyl mono- or polyglycoside as the sole softening agent in a nonionic-anionic surfactant system consisting of a major amount of about 15-30% by weight of a nonionic surfactant and a lesser amount of about 4-12% of an anionic surfactant, in the wash cycle of the laundering operation.
Claim 13
Independent Claim
82 words
A method of simultaneously cleansing and softening fabrics without reducing brightener and detergency performance which comprises treating fabrics with an aqueous liquid detergent composition consisting essentially of about 6 to 30% by weight of a methyl mono- or polyglycoside as the sole softening agent in a nonionic-anionic surfactant system consisting of a major amount of about 15-30% by weight of a nonionic surfactant and a lesser amount of about 4-12% of an anionic surfactant, in the wash cycle of the laundering operation.
Claim 14
Dependent Claim
13 words
The method according to claim 11 wherein said composition also contains a brightener.
Claim 15
Dependent Claim
18 words
The method according to claim 12 wherein the hydrophilic glycoside group contains 1 to 10 reducing saccharide radical.
Claim 16
Dependent Claim
34 words
The method according to claim 11, wherein the nonionic surfactant is selected from the group consisting of primary aliphatic alcohol ethoxylates, secondary aliphatic alcohol ethoxylates, alkylphenol ethoxylates, alcohol ethylene-oxide-propylene oxide condensates and mixtures thereof.
Claim 17
Dependent Claim
26 words
The method according to claim 14, wherein the nonionic surfactant is a C 12 -C 15 aliphatic alcohol having 7 ethylene-oxy groups per mole of alcohol.
Claim 18
Dependent Claim
27 words
The method according to claim 11, wherein the anionic surfactant is selected from the group consisting of alkyl benzene sulfonates, alcohol ether sulfates and ethoxylated alcohol sulfates.

Claim 20
Dependent Claim
22 words
The method according to claim 11, wherein the anionic surfactant content is less than 50% by weight of the nonionic surfactant content.
