If problems occur during the use of OPE-108, it is recommended to immediately stop operation and perform emergency treatment according to safety instructions, while contacting the sales or technical representative of Haian Guoli Chemical Co., Ltd. for professional support.
Common problem self-check and troubleshooting directions
During the use of OPE-108 (Octylphenol Polyoxyethylene Ether), abnormal performance is usually related to system compatibility, process conditions, or storage status. According to Guoli Chemical's product data, you can first self-check the following common situations:
- Emulsification/dispersion effect not as expected: Check HLB value matching (this product has an HLB value of 13.5), confirm whether there are strong electrolytes or extreme pH environments in the system. Although this product is resistant to acids, alkalis, and hard water, extreme conditions still need to verify compatibility.
- Cloudiness or stratification: Check if the storage temperature exceeds 25°C for a long time. The cloud point of this product is 61~67°C (1% aqueous solution), but long-term high-temperature storage may affect stability. If appearance changes due to low temperature in winter, warm to room temperature and stir evenly before use.
- Abnormally high foam: This product is a low-foaming tendency product (foam height approximately 110mm/5min after 85mm by Ross-Miles method at 0.25% aqueous solution). If foam is too high, check for cross-contamination from other raw materials or excessive usage concentration.
- Poor compatibility with other components: This product has strong compatibility, but should avoid contact with strong oxidizing agents, strong alkalis, and active metals.
Emergency treatment (prioritize when personal safety is involved)
OPE-108 is classified as skin corrosion/irritation Category 1B and serious eye damage Category 1 hazardous substance. If personal contact occurs, the following measures must be taken immediately:
- Skin contact: Immediately remove contaminated clothing, rinse with plenty of running water for at least 15 minutes. If burns are obvious, continue rinsing and seek medical attention immediately.
- Eye contact: Immediately lift the eyelids, rinse thoroughly with plenty of running water or normal saline for at least 15 minutes, and seek medical attention promptly.
- Inhalation: Quickly move to fresh air, keep airway unobstructed. If breathing difficulty occurs, seek medical attention immediately.
- Leak treatment: Wear protective equipment, use inert materials such as sand to contain and collect, place in a sealed corrosion-resistant container, avoid entry into sewers.
