The present invention provides a detergent composition comprising a quaternary ammonium compound of formula
R₁R₂R₃R₄N⁺ X⁻
wherein R₁ is C₈-C₁₆ alkyl, each of R₂, R₃ and R₄ is independently C₁-C₄ alkyl or hydroxy alkyl, benzyl, or - (C₂H₄₀)xH where x has a value from 2 to 5, not more than one of R₂, R₃ or R₄ being benzyl, and X is an anion, and a cellulase characterized in that said cellulase provides at least 10% removal of immobilized radio-active labelled carboxymethylcellulose according to the C14 CMC-method at 25 x 10⁻⁶% by weight of cellulase protein in the laundry test solution.
According to the present invention, a preferred cellulase consists of a homogeneous endoglucanase component which is immunoreactive with a monoclonal antibody raised against a partially purified = 43 kD cellulase derived from Humicola insolens DM 1800.
本发明提供了一种洗涤剂组合物,该组合物包含一种式如下的季铵盐化合物
R₁R₂R₃R₄N⁺ X-
其中 R₁ 是 C₈-C₁₆ 烷基,R₂、R₃ 和 R₄ 各自独立地是 C₁-C₄ 烷基或羟基烷基、苄基、或-(C₂H₄₀)xH 其中 x 的值为 2 至 5,R₂、R₃ 或 R₄ 中不多于一个为苄基,且 X 为阴离子、和一种纤维素酶,其特征在于,根据 C14 CMC 法,在洗衣测试溶液中纤维素酶蛋白的重量百分比为 25 x 10-⁶%时,所述纤维素酶对固定化放射性标记的羧甲基纤维素的去除率至少为 10%。
根据本发明,优选的纤维素酶由均匀的内切葡聚糖酶成分组成,该成分对部分纯化的 = 43 kD 纤维素酶具有免疫活性,该纤维素酶来自 Humicola insolens DM 1800。
