Alkali-resistant Penetrant OEP-70 (Isomeric octanol polyoxyethylene ether phosphate) is an anionic surfactant. Proper storage is crucial for maintaining its penetration performance, alkali resistance stability, and overall product quality. Improper storage may lead to product stratification, decreased activity, or contamination, thereby affecting its effectiveness in high-alkali processes such as textile pretreatment, paper pulping, and industrial cleaning.
Regarding the shelf life, there is no explicit shelf life data marked in the database. Generally, for anionic surfactant products (such as phosphate esters), under strict compliance with storage conditions, the shelf life is 12 months from the date of manufacture. The validity period indicated on the product packaging label or the certificate of analysis (COA) provided by the supplier should be referenced. For products beyond the shelf life, it is recommended to conduct small-scale tests to verify performance before deciding whether to continue using them.
| Storage Element | Specific Requirements |
|---|---|
| Environmental Conditions | Cool, dry, well-ventilated warehouse, away from heat sources and ignition sources |
| Temperature Range | 5～40℃, avoid freezing (freezing may cause product stratification) |
| Container Status | Keep sealed to prevent moisture and contamination |
| Prohibited Co-storage | Avoid storage with strong oxidizers, strong acids, and strong alkalis |
| Isolation Requirements | Keep away from food, beverages, and animal feed |
| Shelf Life | Usually 12 months (subject to product label or COA data) |
After opening, use up promptly, and reseal the container immediately after each withdrawal to reduce prolonged contact with air. If the product stratifies or becomes turbid due to low temperature, allow it to slowly return to 15～30℃ and gently stir evenly before use. Do not heat directly. If significant changes in color, odor, or viscosity are observed, stop use and conduct quality verification.
