  • Acidic hard surface cleaners comprising alkylpyrrolidones
    Patent number: 11603509
    Abstract: The need for an acidic liquid hard surface cleaning composition which provides improved removal of grease residues, while still being effective at removing limes-scale, is met by formulating an acidic liquid hard surface cleaning composition with an alkyl pyrrolidone, and additional nonionic surfactant selected from the group consisting of: alkoxylated nonionic surfactant, alkyl polyglucoside, and mixtures thereof, while limiting the amount of anionic surfactant present.
    Type: Grant
    Filed: April 18, 2019
    Date of Patent: March 14, 2023
    Assignee: The Procter & Gamble Company
    Inventors: Raphael Angeline Alfons Ceulemans, Stefanos Kantaridis
  • Alkaline hard surface cleaners comprising alkylpyrrolidones
    Patent number: 11555164
    Abstract: The need for an all-purpose hard surface cleaning composition which provides improved removal of greasy soap scum and water-marks, especially on inclined surfaces, is met by formulating an alkaline composition with an alkyl pyrrolidone, and a co-surfactant selected from the group consisting of: an amine oxide surfactant; a betaine surfactant; and mixtures thereof.
