What is Triton X-114 (CAS 9036-19-5) and how does it differ from Triton X-100?

Triton X-114 (CAS 9036-19-5) is a nonionic octylphenol ethoxylate surfactant with a lower cloud point (approximately 23°C) compared to Triton X-100. This lower cloud point makes it suitable for temperature-driven phase separation applications, including membrane protein extraction and cold-process cleaning formulations.

What is the cloud point of Triton X-114 and why does it matter?

Triton X-114 has a cloud point of approximately 23°C, significantly lower than other common nonionic surfactants. This means the surfactant separates from aqueous solution above this temperature, enabling techniques such as temperature-induced phase partitioning and cold-water rinsing in industrial cleaning applications.

Is Triton X-114 suitable as a direct replacement for Triton X-100?

Not directly. While both are nonionic octylphenol ethoxylates, Triton X-114 has a shorter ethoxylate chain and lower cloud point, giving it different solubility, wetting, and phase behavior characteristics. Formulators should evaluate Triton X-114 based on the specific cloud point requirements of their formulation rather than treating it as a direct substitute.

What are the main industrial applications of Triton X-114?

Triton X-114 is used in nonionic surfactant formulations for industrial cleaning, emulsification, and laboratory biochemical separation. Its low cloud point is specifically leveraged in membrane protein extraction, detergent formulations requiring cold-water phase separation, and industrial processing systems where controlled surfactant solubility is needed.

What purity and packaging options are available for Triton X-114?

Triton X-114 is supplied at 70% active concentration. Standard packaging includes 200 kg iron drums and 50 kg plastic drums. Packaging can be adjusted based on shipment requirements. SDS, TDS, and COA can be provided according to the supplied grade.

What handling and storage considerations apply to Triton X-114?

Triton X-114 should be stored in a cool, dry area away from strong oxidizers. The material has a defined cloud point near room temperature, so storage temperature may affect its physical state. Refer to the SDS for detailed handling, personal protective equipment, and spill response guidance before use.
