Abstract
A structured liquid detergent composition includes water, an anionic detergent surfactant, and a nonionic detergent surfactant. A ratio of the anionic detergent surfactant to the nonionic detergent surfactant is from about 0.5 to about 20. The structured liquid detergent composition further includes a zwitterionic or amphoteric surfactant and a bacterial-derived cellulose network. The structured liquid detergent composition exhibits improved rheological properties.
Claims11
A structured liquid detergent composition comprising:
- water;
- anionic detergent surfactant consisting of alcohol ether sulfate in the amount of about 1% to about 6% by weight of the detergent composition and linear alkylbenzene sulfonate in the amount of about 1% to about 11% by weight of the detergent composition;
- a nonionic detergent surfactant, wherein a weight ratio of the anionic detergent surfactant to the nonionic detergent surfactant is from about 0.5 to about 15;
- a zwitterionic or amphoteric detergent surfactant in an amount of about 0.1% to about 30% by weight of the detergent composition, wherein the zwitterionic or amphoteric detergent surfactant comprises cocoamidopropyl betaine (CAPB) in an amount of about 1% by weight of the detergent composition;
- and
- a bacterial-derived cellulose network present in an amount of about 0.002% to about 0.2%, by weight of the overall structured liquid detergent composition,
- wherein the composition has a storage modulus G′ and oscillatory yield stress of from about 0.5 Pa to about 1.5 Pa.
