PEG600MO, full name Polyethylene Glycol 600 Monooleate, also known as PEG-600 Monooleate or Polyoxyethylene (600) monooleate, belongs to the category of nonionic surfactants. The product typically appears as a light yellow to yellow liquid or paste. It is produced by esterification of polyethylene glycol (PEG-600) with natural oleic acid. Its molecular structure contains both hydrophilic polyoxyethylene segments and lipophilic long-chain fatty acid ester groups, thus providing balanced hydrophilic-lipophilic properties.
As a classic nonionic surfactant, PEG600MO maintains stable performance over a wide pH range and under high water hardness conditions, and is not easily deactivated. It has good compatibility with anionic, cationic and amphoteric surfactants, offering high formulation flexibility. In addition, the product possesses multiple functions including wetting, dispersing, solubilizing and lubricating, allowing a single component to meet various process requirements, thus simplifying formulation design. Because it is derived from natural fatty acids, it is relatively mild and low-irritating, and is especially widely used in personal care products.

Personal Care & Cosmetics: As an O/W emulsifier and solubilizer, widely used in creams, lotions, cleansing oils and facial cleansers to help uniformly disperse oil-soluble active ingredients in water-based formulations, while imparting good skin feel and fine texture.
Textile Industry: Used as an antistatic agent and softener finishing agent, effectively reducing friction between fibers, imparting soft and smooth hand feel, reducing static accumulation during processing. Suitable for finishing processes of various fibers.
Metalworking Fluids: Serves as emulsifier and lubricant in cutting fluids, grinding fluids, etc., promoting stable dispersion of oil components in water, providing auxiliary lubrication, helping extend tool life and improve machined surface quality.
Pesticide Formulations: As a pesticide emulsifier, helps uniformly disperse pesticide active ingredients in aqueous systems, improving wetting and spreading ability of the spray solution, thereby enhancing field application efficacy.
Industrial Cleaners: Suitable for various aqueous industrial cleaning formulations, exhibiting significant emulsifying and dispersing effects on mineral oils, animal and vegetable oils, enhancing detergency efficiency and helping prevent redeposition of soils.
Pharmaceutical Industry: As a solubilizer for poorly soluble drugs, improving dispersion state and dissolution rate, potentially enhancing bioavailability or formulation stability, applicable to oral and topical drug systems.
