Heavy-Duty Liquids, Heavy-duty laundry liquids have gained much importance and much interest in the literature over the last few years. Products in the industry today include both built and nonbuilt heavy-duty liquids. Built heavy-duty liquids are those which contain a builder such as tetrapotassium pyrophosphate (TKPP) or sodium citrate in order to sequester calcium and magnesium hardness ions. Nonbuilt heavy-duty liquids contain no builders and make up for that shortage by considerably increased active contents in order to maintain performance(8-14). Built heavy-duty liquids can have either of the following types of formulations ...

Dishwashing foam stability performance of an LAS-based light-duty liquid (LDL) is strongly affected by the carbon chain distribution, by water hardness, and, under some conditions, by phenyl isomer distribution. Foaming characteristics of C)2 phenyl isomer blends have been reported previously for conditions where LAS is the single anionic surfactant in the formulation (phosphate-built laundry powder) and the level of residual water hardness is low [30,31]. Under these conditions the internal phenyl isomers of C,2 LAS gave better foam performance than the 2-phenyl isomer. 

The use of builders in liquid laundry formulations has effectively been restricted to citrates and fatty acid soaps (in isotropic compositions sold in the U.S. and Europe). Although liquid laundry products can contain tripolyphosphate, soda ash, NTA, and other common builders found in powder laundry, limitations on solubility (in a surfactant matrix) or regulatory concerns have restricted their utilization. There is a finite number of patents covering zeolite-built HDLDs, but problems...

Laundry detergents vary widely in compositions and particular uses and can be partial-built, complete-built, prewash, main wash, bleaching, or enzyme detergents. The liquid detergents can be structured or unstructured.
