OP-13 Octylphenol Ethoxylate (CAS: 9036-19-5) is a non-ionic surfactant with relatively stable chemical properties. However, improper storage can lead to moisture absorption, oxidation, or performance degradation. To ensure that its core functions such as emulsification, wetting, and dispersion remain at optimal levels within the usage period, strict storage management according to specified conditions is essential.
The storage environment is critical to the quality of OP-13. The product appears as a light yellow to colorless transparent viscous liquid or paste. Under low temperature conditions, it may become more viscous or even solidify; this is a physical change and does not affect product quality. However, it is recommended to store within the temperature range to avoid repeated freeze-thaw cycles. High temperatures may accelerate oxidation, leading to darker color and reduced active content. Additionally, due to its hygroscopic nature, the container must be kept sealed to prevent moisture and impurities from entering.
Regarding shelf life, there is no specific value for this product in the Guoli Chemical product database. Generally, for octylphenol ethoxylate non-ionic surfactants, the shelf life is 12 to 24 months from the date of manufacture when stored unopened under strict conditions. It is recommended that users refer to the shelf life indicated on the product packaging label and the COA (Certificate of Analysis) as the primary reference, and perform necessary performance verification before use.
