## Abstract

Treatment compositions that include a surfactant system and an oligoamine, the surfactant system including linear alkyl benzene sulfonate. Related methods of use and preparation of such compositions.

## Claims

### Claim 1

A treatment composition comprising an oligoamine, and a surfactant system,
wherein the oligoamine is diethylenetriamine (DETA) and is present at a level of about 0.01% to about 0.5%, by
weight of the treatment composition,
wherein the surfactant system is present at a level of from about 5% to about 50%, by weight of the composition,
wherein the surfactant system comprises linear alkyl benzene sulfonate (LAS) surfactant and alkyl ethoxylated carboxylate (AEC) surfactant,
wherein the weight ratio of LAS to AEC is from greater than about 75:25 to about 90:10,
wherein the alkyl group of the LAS comprises an average by weight of 11 to 13 carbon atoms,
wherein the surfactant system comprises from about 20% to about 90%, by weight of the surfactant system, of the LAS surfactant, and
wherein the treatment composition is a fabric care composition.

### Claim 2 (depends on 1)

A treatment composition according to claim 1, wherein the surfactant system further comprises alkyl ethoxylated sulfate (AES), nonionic ethoxylated alcohol, or mixtures thereof.

### Claim 3 (depends on 2)

A treatment composition according to claim 2, wherein the surfactant system comprises AES, wherein the weight ratio of LAS to AES is from about 10:90 to about 99:1.

### Claim 4 (depends on 2)

A treatment composition according to claim 2, wherein the surfactant system comprises nonionic ethoxylated alcohol surfactant, wherein the weight ratio of LAS to nonionic ethoxylated alcohol surfactant is from about 10:90 to about 99:1.

### Claim 5 (depends on 1)

A treatment composition according to claim 1, wherein the surfactant system further comprises a zwitterionic surfactant, wherein the zwitterionic surfactant comprises amine oxide.

### Claim 6 (depends on 1)

A treatment composition according to claim 1, wherein the treatment composition comprises an additional treatment adjunct selected from the group consisting of antioxidant, hueing agent, optical brightener, additional chelating agents, enzymes, fatty acids and/or salts thereof, encapsulated benefit agents, soil release polymers, builders, dye transfer inhibiting agents, dispersants, enzyme stabilizers, catalytic materials, bleaching agents, bleach catalysts, bleach activators, polymeric dispersing agents, soil removal/anti-redeposition agents, polymeric grease cleaning agents, amphiphilic copolymers, suds suppressors, aesthetic dyes, perfume, structure elasticizing agents, fabric softeners, carriers, fillers, hydrotropes, solvents, anti-microbial agents and/or preservatives, pH adjusting agents, processing aids, fillers, rheology modifiers, structurants, opacifiers, pearlescent agents, pigments, anti-corrosion agents, anti-tarnishing agents, antifoams, chlorine scavengers, and mixtures thereof.

### Claim 7 (depends on 6)

A treatment composition according to claim 6, wherein the additional treatment adjunct comprises an antioxidant.

### Claim 8 (depends on 6)

A treatment composition according to claim 6, wherein the additional treatment adjunct comprises an additional chelating agent.
