Method of making liquid laundry detergent formulation

A method of making a liquid laundry detergent formulation, consisting of:

• providing a liquid carrier, wherein the liquid carrier is water;
• providing a cleaning surfactant, wherein the cleaning surfactant consists of a mixture of an anionic surfactant and a nonionic surfactant,
• wherein the anionic surfactant is selected from the group consisting of alkyl sulfates, alkyl benzene sulfates, alkyl benzene sulfonic acids, alkyl benzene sulfonates, alkyl polyethoxy sulfates, alkoxylated alcohols, paraffin sulfonic acids, paraffin sulfonates, olefin sulfonic acids, olefin sulfonates, alpha-sulfocarboxylates, esters of alpha-sulfocarboxylates, alkyl glyceryl ether sulfonic acids, alkyl glyceryl ether sulfonates, sulfates of fatty acids, sulfonates of fatty acids, sulfonates of fatty acid esters, alkyl phenols, alkyl phenol polyethoxy ether sulfates, 2-acryloxy-alkane-1-sulfonic acid, 2-acryloxy-alkane-1-sulfonate, beta-alkyloxy alkane sulfonic acid, beta-alkyloxy alkane sulfonate, amine oxides and mixtures thereof;
• and
• wherein the nonionic surfactant is a secondary alcohol ethoxylate;
• and
• selecting a cleaning booster of Formula (I)
• wherein x is 3 to 10;
• wherein y is 5 to 20;
• wherein z is 5 to 30;
• wherein x+y+z≥18;
• wherein x≠z;
• wherein each R is a C7-9 alkyl group, wherein ≥75 wt % of the R groups are branched;
• wherein 99.5 to 100 wt % of the selected cleaning booster of Formula (I) is of Formula (II)
• wherein x is 5;
• wherein y is 9 to 15 and wherein z is 16 to 26;
• providing the selected cleaning booster of Formula (I);
• optionally providing an additive selected from the group consisting of
• an organic solvent selected from the group consisting of ethanol and propylene glycol;
• a builder selected from the group consisting of sodium bicarbonate, sodium carbonate, zeolites, sodium citrate, sodium tripolyphosphate and aminocarboxylates;
• a hydrotrope, wherein the hydrotrope is sodium xylene sulfonate;
• a foam control agent selected from a fatty acid and a polydimethylsiloxane;
• an enzyme selected from the group consisting of protease, cellulase, lipase, amylase and mannanases;
• a preservative;
• a perfume;
• a fluorescent whitening agent;
• a bleach selected from sodium percarbonate, sodium perborate and sodium hypochlorite;
• a dye;
• an additive polymer;
• and mixtures thereof;
• and
• adding the optional additive to the liquid carrier, the cleaning surfactant and the selected cleaning booster of Formula (I) to provide the liquid laundry detergent formulation.
