Emulsifier A-110 (Oil Polyoxyethylene Ester/OEO-110) is a nonionic surfactant with natural oleic acid as the hydrophobic group and polyoxyethylene as the hydrophilic group. At room temperature, it is a light yellow to yellow transparent oily liquid, integrating multiple functions such as emulsification, wetting, dispersion, solubilization, lubrication, and antistatic properties.
Detailed Description
Emulsifier A-110, chemical name Oil Polyoxyethylene Ester, product code OEO-110 (CAS No.: 9004-96-0), also known as Polyethylene Glycol Oleate, PEG Oleate, Polyoxyethylene Oleate, Polyoxyethylene (10) Oleate. This product belongs to nonionic surfactants. In its molecular structure, naturally sourced oleic acid serves as the hydrophobic group, and polyoxyethylene (PEG) chain segments act as the hydrophilic group. The length of the hydrophilic chain is designed to be moderate, achieving an excellent balance between emulsifying power and system adaptability.
This product possesses efficient emulsifying capability and broad chemical tolerance. It can maintain structural stability in acidic, alkaline, and hard water conditions without precipitation or stratification. It also exhibits low foaming tendency—producing minimal foam during application and defoaming quickly, making it particularly suitable for industrial cleaning and circulating systems. Its compatibility is outstanding; it can be compounded with anionic, cationic, nonionic, and amphoteric surfactants in any proportion for synergistic enhancement, enabling flexible construction of composite formulation systems.
In terms of safety and environmental protection, Emulsifier A-110 has very low acute oral toxicity (LD50>2000 mg/kg), classified as practically non-toxic. It has good biodegradability and is categorized as a non-hazardous substance, with lenient transport and storage conditions. It is only mildly irritating to skin and eyes; conventional operations recommend wearing gloves and goggles.

Application Suggestions
Emulsifier A-110, with its multifunctional integrated characteristics, has broad and mature applications in the following six major fields:
- Textile Industry: Used as a core emulsifying component in wool lubricants, spinning oil agents, and pretreatment auxiliaries, providing excellent emulsification, wetting, and antistatic properties, reducing friction and broken ends during carding and spinning, improving the smoothness and bundling of fiber bundles.
- Cosmetics and Personal Care: Serves as a mild O/W emulsifier and solubilizer, suitable for creams, lotions, makeup removers, etc., stabilizing emulsion systems, solubilizing fragrances and active ingredients, imparting a light skin feel.
- Pesticide Formulations: Used in preparing emulsifiable concentrates, aqueous emulsions, microemulsions, with good emulsifying ability for various organic solvents and technical materials, improving the dilution stability of the spray solution and field spreading and penetration performance, enhancing efficacy.
- Metalworking Fluids: Provides both emulsification and lubrication properties, used in cutting fluids, grinding fluids, and rust-proof emulsified oils, effectively cooling and protecting, extending tool life and improving workpiece surface finish.
- Industrial Cleaners: Acts as a powerful degreasing component with excellent detergency and dispersing ability, effective in removing mineral oils and animal/vegetable oils, suitable for hard surface cleaning and metal parts degreasing, low foaming and easy to rinse.
- Emulsion Polymerization: Participates as a primary emulsifier in polymerization systems such as acrylates, styrene-acrylic, etc., improving the mechanical and electrolyte stability of the emulsion, enhancing the adhesion, water resistance, and film-forming properties of the polymer, widely used in coatings and adhesive systems.
Precautions
- It is recommended to wear chemical protective gloves (such as nitrile rubber, thickness >0.3 mm) and safety goggles during operation to avoid direct skin and eye contact.
- Avoid inhalation of vapors or aerosols; use appropriate respiratory protection if ventilation is insufficient.
- Store in a cool, dry, well-ventilated warehouse. Recommended temperature 5°C to 35°C, prevent freezing or excessive heat that may cause product deterioration.
- Keep containers tightly closed, away from fire and heat sources, avoid contact with strong oxidizing agents.
- In case of leakage, collect with inert absorbent materials (such as sand, vermiculite); do not pour into drains or the environment.
- If accidentally gets into eyes, rinse immediately with plenty of water for at least 15 minutes and seek medical attention; for skin contact, wash thoroughly with soap and water.
- This product is not classified as dangerous goods, but during transport, ensure containers are tightly sealed to prevent leakage.
