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 raw material. It has low risk under normal usage conditions. The acute oral toxicity LD50 > 5000 mg/kg (rat), classifying it as a low-toxicity substance. The product is not flammable and has good safety in storage and transportation. However, prolonged or repeated contact may cause skin defatting and dryness, and inhalation of high-temperature steam or mist may cause respiratory discomfort, so caution should not be taken lightly during operation.
This product has low toxicity to aquatic organisms, can be gradually biodegraded in water, and has no bioaccumulation, making it an environmentally friendly product. However, it should be noted that large spills may still cause temporary effects on local water bodies, and spilled material must not enter sewers, surface waters, or soil.
At extremely high temperatures, the product may decompose to produce carbon monoxide, carbon dioxide, and small amounts of irritating organic compounds. Therefore, contact with strong heat sources and open flames should be avoided. Keep separate from strong oxidizers (e.g., peroxides, concentrated nitric acid, permanganates) and avoid contact.
| Protection Area | Protection Requirement |
|---|---|
| Hand Protection | Wear chemical-resistant protective gloves, such as nitrile gloves or neoprene gloves |
| Eye/Face Protection | Wear splash-proof chemical safety goggles or face shield |
| Body Protection | Wear general work clothes or protective apron; wear chemical protective clothing if necessary |
| Respiratory Protection | No special protection required under normal operating conditions; if large amounts of vapor or aerosol are generated, wear a filter-type respirator |
| Engineering Controls | Maintain good general ventilation or local exhaust ventilation in the work area |
During operation, strictly follow these specifications: Avoid contact with eyes, skin, and clothing; do not eat, drink, or smoke; thoroughly wash hands and exposed skin after operation; store work clothes separately and do not take them out of the work area. Although not flammable, take conventional anti-static measures such as equipment grounding during pumping or stirring operations.
| Route of Exposure | Treatment |
|---|---|
| Skin Contact | Immediately remove contaminated clothing and rinse thoroughly with plenty of running water and soap for at least 15 minutes; if redness, pain, or persistent irritation occurs, seek medical attention |
| Eye Contact | Immediately open eyelids and rinse with plenty of running water or saline for at least 15 minutes, rolling the eyes to ensure thorough rinsing; seek medical attention immediately |
| Inhalation | Quickly move the person to fresh air and keep the airway open; if coughing, difficulty breathing, or other discomfort occurs, seek medical attention immediately |
| Ingestion | Rinse mouth immediately with water, do not induce vomiting to avoid aspiration into the respiratory tract; seek medical attention immediately and present the product safety data sheet or label |
Evacuate non-essential personnel from the spill area; personnel handling the spill should wear appropriate protective equipment; prevent spill from entering sewers, surface water, or soil; construct temporary dikes if necessary; cover and collect spilled liquid with inert absorbent materials (e.g., sand, vermiculite) and place in sealed containers; wash the contaminated area with plenty of water and detergent, and collect the wash water for proper disposal; dispose of residues as industrial waste in accordance with local regulations.
Suitable extinguishing agents: water mist, alcohol-resistant foam, dry chemical, or carbon dioxide. Do not use straight water streams on the spill. Firefighters must wear positive-pressure self-contained breathing apparatus and full protective gear. During firefighting, collect firefighting runoff to avoid discharge into the environment without treatment.
This product is widely used in textile printing and dyeing, metalworking fluids, pesticide emulsification, industrial cleaning, leather degreasing, and cosmetics. When used in formulations, it is recommended to determine the dosage according to specific process requirements. Due to its nonionic structure, it can be flexibly combined with anionic, cationic, and other nonionic surfactants to achieve synergistic effects. It exhibits stable performance in acidic and alkaline environments and has excellent hard water resistance, making it suitable for a variety of complex working conditions.
