Alkali-resistant penetrant AEP (Alcohol ethoxylate phosphate, CAS No.: 68439-39-4) is an anionic surfactant. According to the Globally Harmonized System (GHS) of Classification and Labelling of Chemicals, its hazard categories are Skin corrosion/irritation Category 2, Serious eye damage/eye irritation Category 2, and Hazardous to the aquatic environment - Acute hazard Category 3. The signal word is "Warning," and the main hazards are H315 (causes skin irritation), H319 (causes serious eye irritation), and H402 (harmful to aquatic life).
During operation, workers must receive specialized training and strictly follow operating procedures. Operations should be conducted in well-ventilated areas to avoid inhalation of vapors or mists. Core protective requirements include: must wear chemical protective gloves, protective clothing, protective eyewear/face shield (meeting P280 requirements), and the work area should be equipped with eyewash stations and emergency showers. After work, thoroughly wash skin and avoid releasing the product into the environment. Although this product is not flammable or explosive, it is recommended to use non-sparking tools and prevent electrostatic accumulation.
In case of accidental contact, immediately take the following first aid measures: For skin contact, immediately remove contaminated clothing and rinse thoroughly with plenty of running water and soap; if irritation persists, seek medical attention. For eye contact, immediately rinse with plenty of running water or saline for at least 15 minutes and seek medical attention immediately. For inhalation, quickly move to fresh air. For ingestion, rinse mouth with water, do not induce vomiting, and seek medical attention immediately. In case of spillage, wear protective equipment, absorb and collect with inert absorbent materials (such as dry sand, vermiculite), and do not discharge into sewers or water bodies.

Alkali-resistant penetrant AEP is widely used in textile dyeing and finishing (alkali-oxygen one-bath scouring and bleaching, cold pad-batch, mercerizing penetration), leather soaking and degreasing, papermaking deinking and cooking, and metal alkaline cleaning. In these applications, this product is often used in combination with high-concentration alkali or other auxiliaries. Compatibility testing is recommended before use to optimize the process formulation. The specific dosage should be determined based on process requirements and laboratory trials. The Guoli Chemical product database does not provide standard recommended dosages; users need to verify according to their own working conditions.
