Storage Environment Requirements: According to the product safety data provided by Guoli Chemical, this product is a nonionic surfactant with stable chemical properties and is not flammable. The primary storage principle is "cool, dry, and well-ventilated," and it must be kept away from any heat sources, sparks, and open flames. It is recommended to control the warehouse temperature below 40°C, especially avoiding direct sunlight and prolonged high-temperature exposure; otherwise, the product may experience color deepening (color darkening) or slow changes in physical and chemical properties, affecting its usage effectiveness.
Packaging and Isolation Requirements: Containers must always be kept sealed. After opening and taking out material, the container should be re-sealed immediately. This prevents the product from absorbing moisture from the air and also avoids dust or foreign matter falling in. For packaging materials, stainless steel drums, polyethylene (PE) drums, or steel drums with a lining coating are recommended. Avoid prolonged contact between the product and metals such as copper or aluminum to prevent potential chemical reactions. Additionally, this product must be strictly separated from strong oxidizers (such as peroxides, concentrated nitric acid, permanganates, etc.) to eliminate the risk of mixed storage.
Regarding Shelf Life: The product technical data does not explicitly list a specific shelf life. According to industry practices and the chemical stability of such nonionic surfactants (polyoxyethylene oleate), under strict compliance with the above storage conditions (sealed, away from light, cool, dry), unopened products can typically maintain stable performance for 1-2 years. It is recommended to follow the "first in, first out" inventory management principle. If the product has been stored for a long time or exhibits abnormalities such as stratification, significant color deepening, or off-odors, a small sample test should be conducted before use to confirm that key indicators (such as emulsifying power, pH value, etc.) still meet process requirements.
