3‐[(3‐Cholamidopropyl)dimethylammonio]‐1‐propanesulfonate (CHAPS) is a zwitterionic detergent commonly utilized in protein biochemistry‐based applications. This study demonstrates for the first time the successful phase separation of CHAPS via salt addition. Elucidation of consolute solution temperature behavior and determination of binodal curve and tie‐line length (TLL) enabled the subsequent development of CHAPS‐based phase separation systems. The systems were then evaluated using a low‐molecular‐weight dye, Coomassie Brilliant Blue (CBB), and integral membrane protein, cytochrome P450 (CYP) 2C19.
