When encountering problems during the use of PEG-400, first refer to the product safety instructions for emergency handling, and then obtain professional technical support through the official channels of Guoli Chemical.
Detailed Explanation
Polyethylene glycol PEG-400, as a nonionic surfactant, has stable chemical properties and relatively high safety under normal temperature use. However, in practical applications, abnormal situations may still occur due to improper operation, substandard storage conditions, or compatibility issues with the formulation. Common problems include: quality degradation after moisture absorption, incompatibility with other components in the formulation, increased viscosity or even solidification at low temperatures, and discoloration due to excessive storage temperatures.
To address the above issues, start by checking the operation and storage steps: confirm that the container is sealed and stored in a cool, dry environment at 5°C to 30°C, away from strong oxidizers and strong acids and other incompatible substances, and avoid prolonged exposure to air. If the problem involves formulation issues, it is recommended to check whether there are components in the system that antagonize PEG-400, and adjust the addition sequence or ratio.
If the problem cannot be resolved through self-checking, Guoli Chemical provides professional technical support services. An experienced team of application engineers offers one-on-one solutions for specific problems, covering formulation optimization, process adjustment, and application testing.
Emergency Handling Guide
According to GHS classification, PEG-400 is not classified as a hazardous chemical, but in case of accidental exposure, follow the steps below:
| Type of Contact | Emergency Measures |
|---|
| Inhalation | Move the patient to fresh air and keep respiratory tract unobstructed; if symptoms persist, seek medical attention immediately. |
| Skin Contact | Remove contaminated clothing immediately and thoroughly rinse the affected area with plenty of water and soap. |
| Eye Contact | Hold eyelids open and rinse continuously with flowing water or saline solution for at least 15 minutes; seek medical examination as soon as possible. |
| Ingestion | Do not induce vomiting; rinse mouth thoroughly with water and seek medical attention immediately. |
| Spill Treatment | For small spills, cover with inert absorbent material (such as sand) and collect; for large spills, dike and transfer to a sealed dedicated container, and dispose of in accordance with local regulations. Prevent entry into sewers or waterways. |
