Isotridecyl phosphate ester E-1306P is an acidic anionic phosphate surfactant (pH 5.0~7.0 for 1% aqueous solution, pH 2.0~4.0 for 5% aqueous solution) and is irritating. During the entire operation, personal protection must be prioritized: wear impermeable gloves and chemical safety goggles, and appropriate protective clothing to avoid direct contact with skin and eyes. The workplace should be well-ventilated; if natural ventilation is insufficient, local exhaust ventilation or respiratory protective equipment must be used to prevent inhalation of vapors or mists.
This product is harmful to aquatic life and must not be discharged untreated into sewers, surface water, or groundwater. Prevent any leaks or splashes that may contaminate water sources. The product is also highly hygroscopic; keep the container sealed to prevent deterioration due to air exposure. Store in a cool, dry, and well-ventilated environment. The recommended storage temperature range is 5°C to 40°C, avoiding freezing and high temperatures. Container materials should be corrosion-resistant and well-sealed, such as stainless steel or polyethylene.
In case of emergency, skin contact: rinse immediately with plenty of water and soap for at least 15 minutes; eye contact: hold eyelids open and rinse with plenty of water or saline for at least 15 minutes and seek medical attention promptly; inhalation: move to fresh air immediately, if breathing difficulties, administer oxygen and seek medical attention. In case of spillage, small spills: absorb with inert materials such as sand and collect; large spills: contain with dikes and transfer to dedicated waste containers. Wear protective equipment throughout and dispose of according to hazardous waste regulations.
