Emulsifier A-110 (Polyoxyethylene Oleate / OEO-110) is a nonionic surfactant with natural oleic acid as the hydrophobic group and polyoxyethylene as the hydrophilic group. At room temperature, it appears as a light yellow to yellow transparent oily liquid, possessing excellent emulsifying power and system adaptability.
Detailed Description
Emulsifier A-110, chemically named Polyoxyethylene Oleate, trade name OEO-110 (CAS No.: 9004-96-0), also known as Polyethylene Glycol Oleate, PEG Oleate, Polyoxyethylene Oleate, and Polyoxyethylene (10) Oleate. This product is composed of natural oleic acid as the hydrophobic group and polyoxyethylene as the hydrophilic group. The hydrophilic chain segment in the molecular structure has a moderate length, making it a typical nonionic surfactant.
The core characteristics of this product are outstanding: it can rapidly emulsify various animal and vegetable oils, mineral oils, and organic solvents to form stable and fine O/W emulsions; it significantly reduces interfacial tension, promoting liquid spreading on surfaces such as fibers and metals, while effectively dispersing solid particles; it maintains structural stability and functional activity in acidic, alkaline, and hard water conditions without precipitation or stratification; it can be compounded with anionic, cationic, nonionic, and amphoteric surfactants in any proportion for synergistic enhancement; it integrates multiple functions such as emulsification, solubilization, lubrication, and antistatic properties, and produces low foam with quick defoaming during application.

Application Recommendations
Emulsifier A-110 has a wide range of applications, covering six major industrial directions:
- Textile Industry: Used as a core emulsifying component in wool oil, spinning oil, and pretreatment auxiliaries, imparting good cohesion and smoothness to fibers, reducing friction and breakage during carding and spinning.
- Cosmetics and Personal Care: Acts as a mild O/W emulsifier and solubilizer, suitable for creams, lotions, makeup removers, etc., capable of solubilizing fragrances and active ingredients, giving a light skin feel to products.
- Pesticide Formulations: Used in preparing emulsifiable concentrates, oil-in-water emulsions, and microemulsions, with good emulsifying ability for various organic solvents and technical materials, improving dilution stability and field spreading performance.
- Metalworking Fluids: Provides dual performance of emulsification and lubrication, used in cutting fluids, grinding fluids, and rust-proof emulsified oils, effectively cooling and protecting, extending tool life.
- Industrial Cleaners: Serves as a powerful degreasing component, rapidly stripping oil and dirt from metal, plastic, and other surfaces, low foaming and easy to rinse, suitable for spray and immersion processes.
- Emulsion Polymerization: Participates as a reactive emulsifier in polymerization systems such as acrylates and styrene-acrylic, improving the mechanical and electrolyte stability of the emulsion, widely used in coatings and adhesives.
Precautions
- Causes mild irritation to skin and eyes. It is recommended to wear nitrile rubber gloves (thickness >0.3mm) and tight-fitting safety goggles during operation.
- Store in a cool, dry, well-ventilated warehouse, keep the container tightly sealed, away from fire and heat sources, and avoid contact with strong oxidizers.
- Avoid freezing or prolonged exposure to high temperature environments. The recommended storage temperature is 5°C to 35°C.
- Do not dispose of waste into sewers or the environment. Dispose of through qualified waste treatment institutions in accordance with local regulations.
- In case of leakage, absorb with inert absorbent materials (e.g., sand, vermiculite) and collect, preventing entry into sewers or water bodies.
- In case of eye contact, flush immediately with plenty of water for at least 15 minutes. If persistent irritation or redness occurs, seek medical attention promptly.
- This product is not classified as dangerous goods. During transportation, ensure the container is sealed to prevent leakage.
