Abstract
Described herein is a cationic surfactant. Also described herein is a method of using the cationic surfactant, the method including using the cationic surfactant in laundry detergent compositions (for example in combination with an anionic surfactant, nonionic surfactant and/or enzyme).
Claims20
A laundry detergent composition, comprising at least one cationic surfactant of the formula X−
- wherein X represents an anionic counterion, n is from 1 to 5, R1 are independently from each other selected from the group consisting of —CH3, —C2H5, and —C3H7, R2 is selected from the group consisting of linear, branched or cyclic alkyl moieties with 4 to 18 C atoms and R3 independently from each other represent hydrogen, at least one enzyme, and optionally at least one compound selected from the group consisting of anionic surfactants and nonionic surfactants.
A method of using a cationic surfactant of the formula X−
- wherein X represents an anionic counterion, n is from 1 to 5, R1 are independently from each other selected from the group consisting of —CH3, —C2H5, and —C3H7, R2 is selected from the group consisting of linear, branched or cyclic alkyl moieties with 4 to 18 C atoms and R3 independently from each other represent hydrogen, the method comprising using the cationic surfactant for increasing enzyme stability in a laundry detergent composition comprising at least one enzyme.
