Liquid detergent compositions that include a mixture of ecologically-responsible surfactants

1. A detergent composition comprising:

an anionic detergent surfactant blend comprising alkyl ethoxylate sulfate (AES) and sodium lauryl sulfate (SLS), wherein a weight ratio of AES to SLS is from about 4:1 to about 1:4 and wherein the anionic detergent surfactant blend is present in an amount of about 2% to about 10% by weight of the detergent composition; and

a nonionic detergent surfactant comprising an alcohol ethoxylate (AE), wherein a weight ratio of the anionic detergent surfactant blend to nonionic detergent surfactant is from about 3:1 to about 1:3 and wherein the nonionic detergent surfactant blend is present in an amount of about 3% to about 15% by weight of the detergent composition;

water, and

citric acid;

wherein a bio-based carbon content of the detergent composition is from about 50% to about 100% by weight of the overall detergent composition; and

wherein the detergent composition has a viscosity of at least about 300 centipoise.

2. The detergent composition of claim 1 , wherein the detergent composition is formulated as a liquid detergent composition.

3. The detergent composition of claim 1 , wherein the detergent composition is formulated as a unit dose pack detergent composition.

4. The detergent composition of claim 1 , wherein the ratio of the AES to SLS is from about 3:1 to about 1:3.

5. The detergent composition of claim 4 , wherein the ratio of the AES to SLS is from about 2:1 to about 1:2.

6. The detergent composition of claim 1 , wherein the bio-based carbon content of the detergent composition is from about 60% to about 100%.

7. The detergent composition of claim 6 , wherein the bio-based carbon content of the detergent composition is from about 90% to about 100%.

8. The detergent composition of claim 1 , further comprising an additive comprising one or more of: enzymes, peroxy compounds, bleach activators, anti-redeposition agents, neutralizers, optical brighteners, foam inhibitors, chelators, bittering agents, dye transfer inhibitors, soil release agents, water softeners, electrolytes, pH regulators, graying inhibitors, anti-crease components, colorants, scents, processing aids, antimicrobial agents, and preservatives.

9. The detergent composition of claim 1 substantially excluding linear alkylbenzene sulfonate (LAS).

10. The detergent composition of claim 1 , wherein the citric acid is present in an amount of about 3% to about 5% by weight of the detergent composition.

11. A detergent composition comprising:

an anionic detergent surfactant blend comprising alkyl ethoxylate sulfate (AES) and sodium lauryl sulfate (SLS), wherein a weight ratio of AES to SLS is from about 4:1 to about 1:4 and wherein the anionic detergent surfactant blend is present in an amount of about 2% to about 10% by weight of the detergent composition; and

a nonionic detergent surfactant comprising an alcohol ethoxylate (AE), wherein a weight ratio of the anionic detergent surfactant blend to nonionic detergent surfactant is from about 3:1 to about 1:3 and wherein the nonionic detergent surfactant blend is present in an amount of about 3% to about 15% by weight of the detergent composition; and

citric acid present in an amount of about 3% to about 5% by weight of the detergent composition,

wherein a bio-based carbon content of the detergent composition is from about 50% to about 100% by weight of the overall detergent composition, and

wherein the detergent composition substantially excludes linear alkylbenzene sulfonate (LAS), and

wherein the detergent composition has a viscosity of at least about 300 centipoise.
