Polyether L-42 (Poloxamer 122), as a polyoxypropylene polyoxyethylene block copolymer nonionic surfactant, has relatively stable chemical properties. However, improper storage may still lead to moisture absorption, discoloration, or performance degradation. Therefore, strictly following storage guidelines is crucial for ensuring product quality and extending service life.
In an ideal storage environment, the active ingredients of polyether L-42 can remain stable for a long time. This product is not classified as dangerous goods; it is non-flammable and non-explosive, but it should be kept away from heat sources and open flames. Extreme high or low temperatures may cause physical changes (such as viscosity changes, stratification, or crystallization). It is recommended to control the storage temperature between 5°C and 35°C, avoiding freezing or overheating.
Regarding shelf life, the Guoli Chemical product database does not currently provide specific shelf life parameters for this product. According to industry standards for poloxamer polyether nonionic surfactants, under the aforementioned storage conditions and with the container kept intact and sealed, the recommended usage period for polyether L-42 is typically 1-2 years from the date of manufacture. It is advisable to follow the batch production date and expiration date information on the product packaging label, use on a first-in-first-out basis, and use the product as soon as possible after opening.
