FIELD: chemistry.

SUBSTANCE: described is cleaning composition, which contains pH-dependent foaming system and cleaning system, and pH-dependent foaming system can contain initial foaming agent in combination with pH-dependent auxiliary surface-active substance, where pH-dependent auxiliary surface-active substance is selected from molecules of diamine, which have general formula R¹R²-N-R³-N⁺(CH₃)₃X^-, where R¹ represents linear or branched C₈-C₁₆ hydrocarbyl, R² represents linear or branched C₁-C₃ hydrocarbyl, R³ represents linear or branched C₃-C₆ hydrocarbylene, and X represents counterion.

EFFECT: intensification of foaming of pH-dependent auxiliary surface-active substance in pH washing and considerable suppression of foaming in pH rinsing.
