Oleic Acid Polyoxyethylene Ester A-105 (OEO-105) is a nonionic surfactant produced by the addition polymerization of ethylene oxide with natural oleic acid as the raw material. It appears as a light yellow to yellow oily liquid or paste, combining ester groups and polyoxyethylene chains, and is widely used in various industrial scenarios such as emulsification, wetting, and dispersion.
Detailed Description
Oleic Acid Polyoxyethylene Ester A-105 (abbreviated as OEO-105, CAS No.: 9004-96-0) is one of the core products of Haian Guoli Chemical Co., Ltd. Its aliases include Polyethylene Glycol Oleate, PEG Oleate, Oleic Acid Polyoxyethylene Ether Ester, and Polyoxyethylene Oleate Monoester. The product is prepared from natural oleic acid as the starting material through an ethylene oxide addition polymerization process. Its molecular structure contains both hydrophobic fatty acid ester groups and hydrophilic polyoxyethylene chains, endowing it with unique amphiphilic properties.
This product exhibits excellent interfacial activity in both aqueous and oil-phase systems. Its outstanding emulsifying ability enables the formation of stable emulsions with fine particle sizes from various oils and organic solvents. Its excellent wetting properties rapidly reduce interfacial tension, promoting the spreading of liquids on solid surfaces. Additionally, it possesses good dispersing properties, effectively dispersing solid particles and preventing secondary agglomeration. Furthermore, its nonionic structure provides chemical stability over a wide pH range, insensitivity to calcium and magnesium ions, and outstanding hard water resistance. It can also be used in combination with anionic, cationic, and other nonionic surfactants for synergistic effects.

Application Recommendations
Oleic Acid Polyoxyethylene Ester A-105, leveraging its excellent comprehensive performance, has mature applications in the following six major areas:
- Textile Dyeing and Finishing Auxiliaries — Used as a key component in pretreatment scouring agents, leveling agents, and post-finishing softeners to improve fabric treatment uniformity and hand feel. In pretreatment processes, it acts as an efficient wetting agent and penetrant to promote uniform fiber moisture absorption.
- Metalworking Fluids — Used in formulating emulsifiable oils, semi-synthetic and fully synthetic cutting fluids, and grinding fluids, providing emulsification, lubrication, and anti-rust functions to improve machining accuracy and extend tool life.
- Pesticide Emulsifiers — Exhibits excellent emulsification and dispersion effects on various pesticide active ingredients, suitable for pesticide emulsifiable concentrates, oil-in-water emulsions, and other formulations, enhancing the wetting and spreading ability of the spray liquid on crop surfaces.
- Industrial Cleaners — Effectively emulsifies and removes stubborn soils such as mineral oils, animal and vegetable oils, suitable for cleaning metal parts and equipment surfaces, with good detergency and low foaming properties.
- Leather Degreasing Agents — Penetrates deep into leather fibers to emulsify and remove natural oils, providing uniform and thorough degreasing without affecting subsequent leather processing performance.
- Cosmetic Ingredients — Serves as a mild emulsifier and emollient component suitable for developing creams, lotions, makeup removers, and other personal care products, with low skin irritation.
Precautions
- Skin/Eye Contact: Slightly irritating. It is recommended to wear nitrile or neoprene gloves and chemical safety goggles during handling. In case of contact, rinse immediately with plenty of running water.
- Storage Conditions: Store in a cool, dry, well-ventilated warehouse. Recommended storage temperature should not exceed 40°C. Avoid high temperatures and direct sunlight. Keep containers tightly sealed and separate from strong oxidizing agents.
- Packaging Materials: Compatible materials such as stainless steel, polyethylene, or lined steel drums are recommended. Avoid prolonged contact with metals such as copper or aluminum.
- Spill Handling: Prevent spills from entering drains, surface water, or soil. Collect with inert absorbent materials (e.g., sand, vermiculite) and dispose of as industrial waste in accordance with regulations.
- Waste Disposal: Dispose of in accordance with national and local hazardous waste management regulations. Incineration or biological treatment by a qualified waste treatment facility is recommended.
