Isomeric Alcohol Ether Phosphate E-1310P (Isomeric Tridecanol Polyoxyethylene Ether Phosphate) is an anionic surfactant with relatively stable chemical properties, not prone to deterioration under normal storage conditions. To ensure the product quality is always at its best, storage management must strictly follow the recommended conditions. This product remains active over a wide pH range and has good tolerance to acids, alkalis, and hard water, but storage should still avoid incompatible substances.
Regarding the shelf life, according to the product standard of Guoli Chemical, under the premise of following the recommended storage conditions, the suggested shelf life for E-1310P is 12 months from the date of manufacture. For products beyond the shelf life, it is recommended to conduct a small-scale test before use to confirm that various performance indicators (such as wetting power, emulsifying power, pH value, etc.) still meet the application requirements before putting them into use. If the product shows changes such as delamination, increased turbidity, significant color deepening, or abnormal odor, it may indicate deterioration and should not be used further.
| Storage Factor | Specific Requirement |
|---|---|
| Temperature Range | Recommended 5°C to 40°C, avoid extreme high or low temperatures (low temperatures may cause increased viscosity or even solidification; high temperatures may accelerate ester bond hydrolysis) |
| Environmental Requirements | Cool, dry, well-ventilated, avoid direct sunlight and heat sources |
| Container Sealing | Keep the container tightly sealed to prevent moisture evaporation and impurity ingress |
| Suitable Container Materials | Stainless steel, Polyethylene (PE), Polypropylene (PP) |
| Prohibited Container Materials | Carbon steel, aluminum, copper (long-term contact may cause container corrosion or product discoloration) |
| Substances to Avoid | Strong oxidizers, strong acids, strong alkalis, and other incompatible substances |
| Warehouse Management | Follow the First-In-First-Out (FIFO) principle; warehouse floor should be equipped with bunds or spill containment facilities |
In actual use, it is recommended to seal the container immediately after each withdrawal to reduce the product's contact time with air, preventing moisture absorption and oxidation. For users purchasing in large quantities, the product can be divided into small packages to reduce the risk of contamination from frequent opening of large drums. If viscosity increases or slight turbidity occurs in low-temperature environments in winter, it is a normal physical phenomenon. After returning the product to room temperature (15-30°C) and moderate stirring, it can return to a normal transparent state without affecting the use effect.
