MOA-5/AEO-5 (C12-14 fatty alcohol polyoxyethylene (5) ether) is a nonionic surfactant with stable chemical properties, but the ether bond in its molecular structure has certain hygroscopicity, so special attention must be paid to moisture-proofing and sealing during storage. According to data from Guoli Chemical, this product has a closed cup flash point >165°C and is not classified as a flammable dangerous good. It can be handled under general chemical transport conditions.
The appearance of this product is significantly affected by temperature: Above 25°C it is a colorless to slightly yellow transparent liquid; below about 20-25°C it gradually becomes a white paste. This is a normal physical phenomenon for fatty alcohol polyoxyethylene ether products and does not affect product quality. If low-temperature solidification occurs, warm the container slowly in a warm environment before use, never heat directly with an open flame.
Regarding shelf life, the Guoli Chemical product database currently does not provide official shelf life parameters. According to general industry experience, for nonionic surfactant products under unopened, compliant storage conditions, the recommended usage period is generally 1-2 years from the date of manufacture. Once opened, use as soon as possible to avoid moisture absorption and deterioration from prolonged exposure to air. For the shelf life of specific batches, refer to the product's COA (Certificate of Analysis) or directly consult the Guoli Chemical technical service team for confirmation.

During storage, it is recommended to follow the "first in, first out" principle and regularly check container sealing. If the product is not completely used after opening, transfer the remaining material to a smaller container to minimize headspace air, thereby reducing moisture absorption risk. If abnormal phenomena such as separation, increased turbidity, significant color darkening, or off-odor are observed, stop use and contact Guoli Chemical for quality confirmation.
