The stability of three-phase foams stabilized by particles and surfactants (surfactants) of various nature has been studied. The varying degree of hydrophobization of particles by short-chain surfactant hexylamine may be accompanied by a change in the properties of the dispersed system from high-strength and low-stability foams to structured low multiplicity. A decrease in the stability of foams stabilized by hydrophobized titanium oxide particles at a concentration of long-chain surfactant - cetylammonium bromide Cпав≥Сккм may be due to a decrease in the edge angle of wetting of solid particles.
