The paper considers the influence of the nature of foaming agent on the properties of foams. Based on the analysis of the market of modern pore-forming additives, from the number of foaming agents the most widely used components, as well as novelties of the market, have been chosen. The technical characteristics of the foaming agents provided on the market are reviewed. The influence of foaming agent concentration, composition and base on the foam expansion, stability and density of foams is studied in the paper. The optimum ("working") concentrations of foaming additives are determined taking into account their stability. The stability of foams formed on the basis of working solutions in porous systems of various compositions is studied. Based on the complex of studies, the protein foaming agents are ranked according to the degree of their effectiveness, according to the data on the physical and technical properties of foams obtained on their basis.
