Abstract
Abstract A liquid, bleach softener composition for use in one or more of the wash, rinse and tumble dry cycles of a laundering process comprising a water soluble peroxy bleaching agent, at least 50% thereof being hydrogen peroxide, and a water soluble cationic nitrogen softener compound, at least 50% thereof being an aliphatic, quaternary ammonium compound and/or a cationic heterocyclic imide such as an imidazolinium or pyridinium compound in a weight ratio of softener to peroxy bleaching agent of about 5:7 to 5:1.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
106 words
A liquid bleach, fabric-softener composition beneficially adapted for use in one or more of the wash, rinse and tumble drying cycles of a fabric-laundering process consisting essentially of, by weight, from about 3 to 10% of water soluble peroxy bleaching agent, at least about 50% thereof being hydrogen peroxide and from about 3 to 25% of water soluble fabric softener compound, at least about 50% thereof being cationic amine softener, the weight ratio of softener to peroxy bleach being from about 5:7 to 5:1, the balance of said composition being water or a mixture of water with up to about 10% of water soluble lower alkanol.
Claim 2
Dependent Claim
106 words
A liquid bleach, fabric-softener composition beneficially adapted for use in one or more of the wash, rinse and tumble drying cycles of a fabric-laundering process consisting essentially of, by weight, from about 3 to 10% of water soluble peroxy bleaching agent, at least about 50% thereof being hydrogen peroxide and from about 3 to 25% of water soluble fabric softener compound, at least about 50% thereof being cationic amine softener, the weight ratio of softener to peroxy bleach being from about 5:7 to 5:1, the balance of said composition being water or a mixture of water with up to about 10% of water soluble lower alkanol.
Claim 3
Dependent Claim
15 words
A composition according to claim 1 wherein said bleaching agent consists entirely of hydrogen peroxide.
Claim 4
Dependent Claim
16 words
A composition according to claim 2 wherein said softener consists entirely of cationic amine softener agent.
Claim 5
Dependent Claim
13 words

Claim 6
Dependent Claim
12 words
A composition according to claim 3 wherein said softener is hexadecyltrimethyl-ammonium bromide.
Claim 7
Dependent Claim
13 words
A composition according to claim 3 wherein said softener is 1-methyl-1-(tallowamidoethyl)-2-tallow imidazolinium chloride.
Claim 8
Dependent Claim
14 words

Claim 14
Dependent Claim
30 words
A composition according to claim 1 containing up to 50% of a peroxy bleach compound selected from the group consisting of alkali metal and ammonium perborates, percarbonate, monopersulfates and monoperphosphates.
Claim 15
Dependent Claim
11 words
