Aqueous solution properties of ZETESOL surfactant preparations

Abstract

Surface-active, optical and electrical proper ties of surfactant specimens ZETESOL ZN and ZETESOL MG water solution were investigated using various analysis methods (stalagmometry, turbidimetry, refractometry, conductometry). The quantitative characteristics of adsorption process such as the Langmuir’s maximum adsorption, the consta nts of Shishkovsky’s equation were calculated. It was determined that the specimens investigated have great surface activity on the frontier between surfactant specimens water solutions and air. The resu lts of obtained by turbidimetric method show that the specimens are colloidal systems and their critical concentration of micelle formation are coequal. The admixture (laureth-3, phenoxyethanol, sulfates of metals) have the positive influence on the effect of aggregation in colloidal solutions of surfactant specimens. The specimen ZETESOL MG has greater effect on micelle formation than the specimen ZETESOL ZN because of larger quantitive constant in its composition. The characteristic curves “electro conductivity – concentration of water solution of surfactant specimens” were carried out by conductometric method. The electrical properties of anionic specimens depend on the ionic qualitative composition of systems. It was established that electro-conductivity of ZETESOL MG water solutions is higher than that of ZETESOL ZN water solutions due to higher electrolyte (MgSO [4]) concentration. The investigations showed that the specimens ZETESOL group could be used in composition of hygienic detergents as foam-producing agents and stabilizers of foams.
