PEG-1000/1500 (polyethylene glycol) is a white waxy solid at room temperature, with a melting point range of 37~54°C. Therefore, special attention should be paid to prevent the product from melting and caking when ambient temperature is high. According to the Guoli Chemical Product Database, this product is hygroscopic and must be stored in moisture-proof sealed packaging to isolate it from moisture in the air, preventing quality degradation due to moisture absorption.
The storage warehouse should be kept cool, dry, and well-ventilated, avoiding direct sunlight. The product should be kept away from incompatible substances such as strong oxidizers. Under recommended storage conditions, PEG-1000/1500 is chemically stable and its shelf life is guaranteed.

Given the low melting point of PEG-1000/1500 (37~54°C), during high-temperature transportation and storage in summer, it is recommended to keep the warehouse temperature below the product's melting point to avoid softening, deformation, or caking, which could affect subsequent use and weighing. Unused product after opening should be immediately resealed to prevent moisture absorption.
