Polyethylene Glycol 400 Dioleate CAS 9005-07-6

Polyethylene Glycol 400 Dioleate (PEG 400 Dioleate) is a nonionic ester‑type surfactant used as an industrial ingredient in formulated chemical systems. Identified by CAS No. 9005-07-6, this material is produced by esterification of polyethylene glycol with oleic acid, resulting in a diester structure that provides emulsification, wetting, and dispersion functions. It is commonly applied in nonionic surfactant formulations where balanced hydrophilic‑lipophilic performance and formulation compatibility are required at the industrial processing level. Supply is available with competitive factory pricing, supports customized specifications, and includes MSDS, TDS, COA documentation for bulk supply.

Product Overview

PEG-400 Dioleate, also supplied as Polyethylene Glycol 400 Dioleate, is a nonionic diester surfactant prepared from polyethylene glycol and oleic acid. It is more appropriately positioned as an industrial surfactant and emulsifier raw material rather than as a consumer-facing finished ingredient.

This product is commonly used in oil-phase and water-in-oil systems where emulsification, wetting, dispersion, and lubricity are required. Technical documents such as COA, TDS, and SDS may be provided according to the supplied grade.
