Triton X-100 (C
₁₄H
₂₂O(C
₂H
₄O)_n) is a nonionic surfactant that has a hydrophilic polyethylene oxide chain (on average it has 9.5 ethylene oxide units) and an aromatic hydrocarbon lipophilic or hydrophobic group. The hydrocarbon group is a 4-(1,1,3,3-tetramethylbutyl)-phenyl group. Triton X-100 is closely related to IGEPAL CA-630, which might differ from it mainly in having slightly shorter ethylene oxide chains. As a result, Triton X-100 is slightly more hydrophilic than Igepal CA-630 thus these two detergents may not be considered functionally interchangeable for most applications.^[3]

Triton X-100 was originally a registered trademark of Rohm & Haas Co. It was subsequently purchased by Union Carbide and then acquired by Dow Chemical Company upon the acquisition of Union Carbide. Soon afterward (in 2009), Dow also acquired Rohm & Haas Co.
