O. Brutskaya Belarusian State Technological University FOAM FORMATION IN AQUEOUS SOLUTIONS OF BINARY MIXTURES OF ANIONIC AND NONIONOGENIC SURFACE ACTIVE SUBSTANCES The influence of the concentration of a mixture of anionic (sodium laureth sulfate, ASCO 4-/70) and nonionic (diethanolamide coconut oil fatty acids, Rokamid KAD) surfactants on the foaming capacity of their aqueous solutions, stability and density of the foams were investigated. The ratio of nonionic and anionic surfactant was : 3 and : 5; surfactant concentration in the solution was varied in the range of g/l. Research was performed on Ross-Miles equipment (temperature 6 0 C). It is found that that foaming capacity was better and stability of foams was more significant with the ratio on : 3. The addiction between the foam number and density of foam was the following: with increasing foaming capacity the density of foam decreases. All foams prepared within the parameters studied are highly stable and their stability is more than 90%. In accordance with the requirements of STB foamy number of hygienic cleansers should not be less than 00 mm, and the foam stability not less than 80%. These requirements are obtained for ratios of nonionic and anionic surfactants of : 3 at a concentration of 0.5 g/l and more. Key words: mixture of anionic and nonionic surfactants, sodium laureth sulfate, coconut diethanolamides, fatty acids, foam foaming, foam stability, foam density ( ). - -,. - [, ], -,, ( ) - -,.
