Abstract

Treatment compositions that include relatively low levels of an oligoamine. Related methods of use and preparation.

First claim

What is claimed is:

1. A treatment composition comprising:
from about 0.1% to about 0.4%, by weight of the treatment composition, of an oligoamine,
wherein the oligoamine is diethylenetriamine (DETA) according to

 or
Methylated DETA according to

 and

from about 5% to about 40%, by weight of the treatment composition, of a surfactant system,
wherein the surfactant system comprises an anionic surfactant,
wherein the anionic surfactant comprises linear alkyl benzene sulfonate (LAS), alkyl ethoxylated sulfate (AES), or mixtures thereof,

wherein the surfactant system further comprises an nonionic surfactant,
wherein the nonionic surfactant comprises alkoxylated fatty alcohols having from 12 to 14 carbon atoms, and an average of from about 7 to about 9 ethoxy groups;
an additional chelating agent selected from the group consisting of diethylenetriaminepentaacetic acid, methylglycinediacetic acid, glutamic-N,N-diacetic acid, any suitable derivative thereof; salts thereof; and mixtures thereof;
an additional treatment adjunct;
wherein the treatment composition is a liquid laundry detergent.

2. A treatment composition according to claim 1 , wherein the treatment composition comprises from about 0.1% to about 0.2%, by weight of the treatment composition, of the oligoamine.

3. A treatment composition according to claim 1 , wherein the additional treatment adjunct is selected from the group consisting of: a surfactant system, fabric conditioning active (FCA), 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, 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.

4. A treatment composition according to claim 1 , wherein the anionic surfactant is pre-neutralized with an alkali metal, an alkali earth metal, an amine, or mixtures thereof.

5. A treatment composition according to claim 1 , wherein the additional treatment adjunct comprises an antioxidant.

6. A treatment composition according to claim 1 , wherein the additional treatment adjunct comprises a whitening or brightening agent selected from the group consisting of a hueing agent, an optical brightener, and mixtures thereof.

7. A treatment composition according to claim 1 , wherein the oligoamine and the additional chelant are present in the treatment composition at a combined level of from about 0.1% to about 10%, by weight of the treatment composition.

8. A treatment composition according to claim 1 , wherein the weight ratio of the oligoamine to the additional chelant is from about 1:1 to about 1:50.

9. A treatment composition according to claim 1 , wherein the additional treatment adjunct comprises an enzyme selected from the group consisting of protease, amylase, lipase, cellulase, phosphodiesterase, pectate lyase, and mixtures thereof.

10. A treatment composition according to claim 1 , wherein the treatment composition is in a form selected from the group consisting of: a liquid composition, a granular composition, a single-compartment pouch, a multi-compartment pouch, a dissolvable sheet, a pastille or bead, a fibrous article, a tablet, a bar, a flake, a dryer sheet, and mixtures thereof.

11. A process of treating a surface, the process comprising the steps of:
providing a surface, and
contacting the surface with a composition according to claim 1 , optionally in the presence of water.
