对氯间二甲苯酚（4-chloro-3,5-dimethylphenol）是一种抗菌化合物广泛用于控制革兰氏阳性菌，但对革兰氏阴性菌、结核分枝杆菌、真菌和病毒作用有限，常被添加至化妆品，消毒液，洗手液中。它也被广泛地应用于抗菌香皂中，比如滴露。研究表明，它透过对细胞膜电位进行干扰来达到抗菌作用

本物质对人类与其它哺乳动物没有显着毒性, 对鸟类基本无毒, 对淡水无脊椎动物有中等毒性, 对鱼类则有剧毒。 该物质是一种温和的皮肤刺激剂, 并可能在一些人中导致过敏反应; 常与氯化甲酚 (Chlorocresol) 有交叉过敏性。

Chloroxylenol (4-chloro-3,5-dimethylphenol) is a broad spectrum antimicrobial chemical compound used to control bacteria, algae, fungi and virus. It is used in hospitals and households for disinfection and sanitation. It is also commonly used in antibacterial soaps, wound-cleansing applications and household antiseptics such as Dettol liquid (to which it contributes its distinctive odor), cream and ointments. Studies have shown an antimicrobial activity which is enhanced by additives. Its antibacterial action is due to disruption of cell membrane potentials. Developed in Europe in the 1920s and used in the United States since the 1950s, Chloroxylenol is one of the most mature antimicrobial agents.
