Quaternary ammonium compounds：四氨化物,四級胺的家族總稱,陽性界面活性劑（cationic surface active agents）：又稱為四級銨化合物（quaternary ammonium compounds；QACs）、陽性肥皂（陽離子肥皂，cationic soap），或逆性肥皂（invert soap）。
主要由一個氮原子鍵結四烷基所形成的化合物。目前市面大多數為烷基苯亞基化氯（alkyl benzalkonium chlorides）或是西曲溴銨（Cetrimide），可黏在細菌的細胞膜上，造成孔洞，來達到抑菌的效果。其對gram-positive的細菌的殺菌效果較 gram-negative細菌為佳，但對於黴菌，TB菌，細菌孢子類的抑菌效果就很弱。也因此容易滋生gram-negative細菌。但因其對皮膚的刺激較少，故可用於清潔皮膚表面，燒傷病人亦合用。目前市面上，常見於去頭皮洗髮水、美琪藥皂、隱形眼鏡消毒藥水，並可作化妝品防腐劑。其目前被美國食品藥物管理局暫時歸類成第三級（category IIISE）的殺菌洗手劑，代表其安全性及有效性仍須進一步證實。
四價胺化合物(Quaternary ammonium compounds)：許多四價胺化合物經常與其它殺菌劑(如酒精)混合使用，對細菌營養體和含脂病毒有效，某些種類，如 benzalkonium chloride 可當做防腐劑。某些四價胺化合物殺菌活性受到有機物、水的硬度、和陰離子清潔劑的影響而降低，使用此類化合物做為消毒劑，標的物應先進行清洗工作。四價胺化合物不易進行生物分解，易累積於環境中。
Quaternary Ammonium Compounds ，又叫做四級物，在鹼性ph值下能表現最大的活性。它會和有機物質結合而限制其作用。 四級物的主要優點是低組織毒性和高作用速度。最大的缺點是當有機物質存在時，會明顯降低其活性。水中的礦物質也會減少它的效果。重複接觸會造成皮膚乾燥化。並且帶負電的肥皂和陰離子清潔劑會中和它們的抗微生物效果。
