High-quality polyether F-6 (castor oil polyoxyethylene ether, CAS: 61791-12-6) is a stable non-ionic surfactant that is unlikely to have abnormalities under normal use conditions. However, in practical applications, problems may arise due to improper operating conditions, compatibility issues, or storage methods. When encountering problems, it is recommended to follow the steps below to troubleshoot and handle:
First, identify the type of problem. Common issues include: unsatisfactory defoaming effect (possibly due to insufficient dosage or system pH deviating from the applicable range), product stratification or turbidity (possibly due to solidification caused by low storage temperature, or deterioration due to high temperature exposure), incompatibility with other additives in the formulation (precipitation or flocculation), and personal safety issues caused by leakage or contact. Different problems correspond to different troubleshooting directions.
Second, consult the emergency treatment measures in the product safety instructions (see below). For emergencies involving personal contact (skin, eye contact or inhalation, ingestion), immediate first aid measures must be taken and medical attention sought promptly. For process or formulation issues, it is recommended to record detailed process conditions (temperature, pH, dosage, compatible components, etc.) and then contact the Guoli Chemical technical support team for professional analysis.
| Problem phenomenon | Possible cause | Recommended measure |
|---|---|---|
| Poor defoaming/inhibiting effect | Insufficient dosage; system temperature or pH exceeds applicable range; competition with anionic additives | Gradually increase dosage for testing; check if process conditions are within recommended range; optimize feeding sequence |
| Product stratification, turbidity or precipitation | Solidification due to low storage temperature; deterioration due to high temperature exposure; exceeding 12 months shelf life | Return to 5°C~35°C and stir evenly before trial; if deteriorated, dispose as waste |
| Incompatibility with formulation system | Adverse reaction with compatible components (strong acids, strong bases, strong oxidizers) | Confirm compatibility; adjust the order of adding components in the formulation; conduct small-scale test |
| Product color deepens | Use of inappropriate container materials such as copper or aluminum | Replace with stainless steel, glass or HDPE containers |
Skin contact: Immediately remove contaminated clothing, rinse with plenty of running water and mild soap for at least 15 minutes. If persistent redness or irritation occurs, seek medical attention.
Eye contact: Lift eyelids, rinse thoroughly with plenty of running water or saline solution for at least 15 minutes. If discomfort persists, seek medical attention immediately.
Inhalation discomfort: Quickly move to fresh air, keep airway unobstructed. If difficulty breathing, administer oxygen and seek medical attention promptly.
Ingestion: Rinse mouth with water, do not induce vomiting (unless directed by a professional), give a small amount of water to dilute, and seek medical attention as soon as possible, presenting the product label.
Leak handling: Use inert absorbent materials (diatomaceous earth, vermiculite, dry sand) to contain the leaking liquid, prevent entry into drains and soil, collect and dispose according to chemical waste regulations.
