  • Publication number: 20240287418
    Abstract: The present invention relates to cleaning compositions comprising at least one lipolytic enzyme having polyesterase activity and at least one cellulase. The cleaning compositions described herein are suitable for use in cleaning processes and include detergent compositions, such as laundry detergent compositions, in particular liquid laundry detergent compositions. The present invention further relates to a method for cleaning textiles and to the use of the cleaning composition according to the invention for removing stains as well as for reducing pilling effects and/or increasing the anti-graying effect of the cleaning composition. Furthermore, the invention is directed to the use of at least one lipolytic enzyme having polyesterase activity and at least one cellulase for synergistically improving the anti-pilling performance and/or anti-graying performance of a cleaning composition comprising lipolytic enzyme having polyesterase activity and cellulase.
