| 摘要 |
Laundry detergent compositions giving improved oily soil detergency in the machine wash, especially on knitted cotton and knitted polyviscose fabrics, contain an anionic sulphonate surfactant and a zwitterionic betaine surfactant in a weight ratio of 2:1 to 99:1, preferably 3:1 to 25:1. The preferred anionic surfactant is linear alkylbenzene sulphonate and the preferred betaine surfactant is cocoamidopropyl betaine.
