Penetrant JFC-2 (isooctanol polyoxyethylene ether, CAS: 9002-93-1) is a nonionic surfactant with stable chemical properties. However, under improper storage conditions, it may absorb moisture, stratify, or deteriorate. According to the product safety data of Guoli Chemical, the core storage principles are avoid light, seal, control temperature, and prevent moisture. Ensure the container is intact and tightly closed to prevent the ingress of water and impurities. This product remains liquid below 10℃, but prolonged low temperatures may cause turbidity or stratification. After returning to room temperature and stirring evenly, it can generally be used.
Regarding shelf life, there is no clear shelf life parameter in the Guoli Chemical product database. Generally, for nonionic surfactants like isooctanol polyoxyethylene ether, under strict compliance with storage conditions, the shelf life from the date of production is typically 2 years. It is recommended that users regularly inspect the product's appearance (should be a colorless to slightly yellow transparent liquid). If severe turbidity, stratification, odor, or noticeable color deepening occurs, it may indicate that the product has deteriorated and should be stopped for use and quality tested. For products beyond the shelf life, it is advisable to conduct a small-sample test to confirm performance before deciding whether to continue use.

Handling Management: After each use, immediately seal the container to avoid prolonged exposure to air. It is recommended to use dedicated tools for extraction to prevent cross-contamination. For IBC totes or large packaging, use pump or valve dispensing to reduce the frequency of opening.
Regular Inspection: It is recommended to check the appearance and container seal integrity of in-stock products every quarter. If container deformation, leakage, or abnormal product appearance is found, isolate and evaluate promptly. During winter, especially pay attention to prevent the product from being kept below 5℃ for extended periods; if necessary, provide moderate insulation to the warehouse.
First In, First Out: Follow the "first in, first out" principle in warehouse management, prioritizing batches with earlier production dates to avoid product overstocking beyond shelf life. Each batch should retain complete inspection documents and batch traceability information.
