  • Patent number: 8877696
    Abstract: A cleaning composition may comprise a pH-switchable sudsing system and a cleansing system. The pH-switchable sudsing system may comprise a primary sudsing agent in combination with a pH-switchable co-surfactant. The pH-switchable co-surfactant is selected from diamine molecules having a general formula R1R2—N—R3—N+(CH3)3X?, where R1 is a linear or branched C8 to C16 hydrocarbyl, R2 is a linear or branched C1 to C3 hydrocarbyl, R3 is a linear or branched C3 to C6 hydrocarbylene, and X is a counteranion. The tertiary amine nitrogen of the pH-switchable co-surfactant has a pKa value. When the tertiary amine nitrogen is unprotonated, the pH-switchable co-surfactant may provide a suds-boosting effect in washing solutions at a washing pH above the pKa. When the tertiary amine nitrogen is protonated, the pH-switchable co-surfactant may provide a suds-reducing benefit in rinse waters at a rinse pH below the pKa.
