Surfactant Composition for Laundry Application

US Patent No. 11,505,766 B2 (Daniel Thomas Piorkowski); Henkel AG & Co. KGaA has patented a liquid laundry detergent composition comprising a Diallyldialkylammonium chloride (DADMAC) acrylic acid co-polymer; water; active surfactant surfactant comprising an alcohol ethoxysulfate (AES), a linear alkylbenzene sulfonate (LAS), and a non-ionic surfactant (NI).

The composition has a turbidity of about 50 NTUs or less.

The weight ratio of the AES, LAS, and NI falls within a four-sided region of a ternary plot. The four-sided region is defined by four points of the ratio of AES:NI:LAS:
(i) 0.85:0:0.15;
(ii) 0.85:0.15:0;
(iii) 0.4:0.6:0;
(iv) 0.4:0:0.6.
