Hand dishwashing liquids (HDLs) are one of the most popular groups of household chemicals. They can be manufactured with the use of the coacervation process. The process can be performed with sodium chloride as a triggering agent. The study below analyzes the effect of the type of nonionic surfactant (adducts of ethylene oxide to lauryl alcohol) on the physicochemical and functional properties of HDLs in the coacervate form. It has been demonstrated that the type of nonionic surfactant used in the formula has an influence on the conditions of occurrence of the coacervation process and on the physicochemical and functional properties of finished HDLs in the coacervate form. Moreover, the studies have shown that a considerable number of starting active compounds used in the formulas are transferred into the coacervate phase as a consequence of the coacervation process.
