| Abstract: | A comparative study of the surface activity of different brands of oiling agents was conducted. It was found that the laminar
compositional instability, manifested by the nonmonotonic dependence of the surface tension of emulsions on their concentration
and/or a change in it during storage, is characteristic of all products investigated. Data indicating the characteristic nature
of the dependences of the surface tension of aqueous emulsions of oiling agents on the concentration and the possibility of
using them for identifying oiling agents were obtained.
