US Patent No. 11,655,432 B2 (Wei Sun); Henkel AG & Co. KGaA, Duesseldorf, has patented a detergent composition that contains:
• 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;
• 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.
The bio-based carbon content of the detergent composition is 50-100% by weight of the overall detergent composition. The detergent composition has a viscosity of at least about 300 centipoise.
