How to store environmentally friendly penetrating agent JFC? How long is its shelf life?

Environmentally friendly penetrating agent JFC should be stored in a cool, dry, and well-ventilated environment at 5°C to 40°C, and the container must be kept sealed; the database does not indicate a specific shelf life, and before use after long-term storage, be sure to check whether the product properties are normal.

Detailed Description

Environmentally friendly penetrating agent JFC (fatty alcohol polyoxyethylene ether, CAS: 68439-50-9) is a nonionic surfactant with good chemical stability under normal conditions and resistance to acid and alkali. However, it has hygroscopicity, so moisture-proofing and container sealing during storage are key to ensuring product quality. This product is a non-flammable liquid with a flash point greater than 150°C (closed cup), non-explosive, but still needs to be kept away from high temperatures and ignition sources.

Regarding the shelf life, the Guoli Chemical product database does not have a specific marking for this parameter. According to general experience in the nonionic surfactant industry, under the premise of strictly meeting the recommended storage conditions, it can usually be stably stored for 1 to 2 years. The most critical principle clearly stated in the database is: Before use after long-term storage, check whether the product properties are normal, such as whether the appearance is still a colorless to slightly yellow transparent liquid, and whether there is any abnormal condition like layering or turbidity.

Pre-Use Inspection Recommendations

For products stored for a long time, perform the following checks before use:

• Observe whether the appearance remains colorless to slightly yellow transparent liquid, without turbidity, layering, sedimentation, or discoloration.
• Check whether the container is intact and sealed, with no signs of leakage, and confirm that the product has not absorbed moisture and deteriorated.
• If necessary, take a sample for small-scale test to verify whether the penetrating power (standard value ≤5 seconds) and emulsifying performance meet the process requirements.
• If the product properties are abnormal (such as layering, turbidity, or significantly deepened color), stop using and consult Guoli Chemical technicians.

Precautions

• This product causes skin irritation (H315) and serious eye irritation (H319). Wear protective gloves and goggles when handling.
• This product is harmful to aquatic life with long-lasting effects (H412). Do not discharge directly into sewers, surface water, or soil.
• Packaging specifications: 50kg plastic drum, 200kg plastic drum, IBC tote. Choose the appropriate packaging according to the usage to reduce long-term exposure after opening.
• The warehouse should be equipped with emergency eyewash and shower equipment for emergency use.
