Method of making an opacified liquid detergent composition using a divalent cation solution

A method of making an opacified liquid detergent composition, said method comprising the steps of:

• A) combining at least one anionic surfactant, a fatty acid, and water to form a mixture having a transparent optical appearance;
• B) dissolving a calcium and/or magnesium salt into a solvent to form a salt solution comprising calcium and/or magnesium divalent cations;
• C) adding the salt solution comprising the calcium and/or magnesium divalent cations to mixture A;
• and
• opacifying the mixture as the calcium and/or magnesium divalent cations interact with the fatty acid and the anionic surfactant to form the opacified liquid detergent composition in the absence of a microplastic opacifier, the opacified liquid detergent composition having a turbidity value of greater than about 250 turbidity units (NTUs) measured utilizing a turbidity meter at about 24° C.;
• wherein:
• 1) the anionic surfactant is selected from the group consisting of linear alkylbenzene sulfonate, an alcohol ethoxy sulfate having a backbone including from 8 to 20 carbon atoms and ethoxylated with from about 1 to about 10 moles of ethylene oxide, and combinations thereof;
• 2) the calcium salt is selected from the group consisting of calcium chloride, calcium carbonate, calcium citrate, calcium lactate, calcium gluconate, calcium sulfite, calcium bisulfite, calcium sulfate, and combinations thereof, and the magnesium salt is selected from the group consisting of magnesium chloride, magnesium chloride hexahydrate, magnesium citrate, magnesium sulfite, magnesium bisulfite, magnesium sulfate, and combinations thereof;
• and
• 3) the fatty acid is obtained from palm kernel oil and has a backbone including from 12 to 20 carbon atoms.
