Refined coconut oil 6501-98% (Ninol) is a high-purity coconut fatty acid diethanolamide nonionic surfactant, with good chemical stability, but storage conditions directly affect product color, active content, and performance. Improper storage may lead to color deepening, stratification, viscosity reduction, or microbial growth, thereby affecting core functions such as thickening and foam stabilization.
Regarding shelf life, there is no clear official shelf life data in this product database. However, according to common industry practice, similar high-purity alkanolamide products, stored in original sealed containers in a cool, dry place, typically have a shelf life of 12 to 24 months from the date of manufacture. It is recommended to refer to the production date and shelf life marked on the product packaging. For products beyond the shelf life, small-scale validation tests should be conducted before deciding whether to use them.
| Storage Factor | Specific Requirement | Description |
|---|---|---|
| Ambient Temperature | Recommended not exceeding 40°C, avoid freezing | High temperature accelerates amine value increase and color deepening; low temperature may cause product solidification or precipitation, but after thawing and stirring evenly, it can generally recover |
| Ambient Humidity | Cool, dry | The product has some hygroscopicity; moisture may affect active content and increase microbial risk |
| Ventilation Condition | Well-ventilated | Maintain air circulation in the warehouse to avoid accumulation of volatile substances |
| Container Status | Keep tightly sealed, prevent leakage | Use as soon as possible after opening, seal immediately after material removal; prolonged exposure to air will absorb moisture and carbon dioxide |
| Keep away from heat/fire sources | Must keep away | Although not flammable, heating may produce harmful gases |
| Incompatible substances | Store separately from strong oxidizers and acids | Contact with strong acids or strong oxidizers may cause chemical reactions, leading to product deterioration |
| Isolation requirements | Keep away from food, beverages, and animal feed | It is an industrial chemical and should not be mixed with food items |
To ensure the best performance of the product, it is recommended to follow the "first-in, first-out" inventory management principle. Each time material is taken, use clean and dry tools to avoid bringing water or impurities into the packaging drum. For large packages (e.g., 200kg drums), it can be divided into smaller containers for use to reduce the opening frequency of the large drum and minimize contamination risk.
If the product shows slight turbidity, stratification, or a small amount of sediment at the bottom during storage, it is usually a physical change. After ruling out microbial contamination, it can still be used normally after stirring evenly and passing small-scale tests. However, if there is obvious off-odor (rancid, ammonia-like, etc.), severe discoloration, or mold growth, discontinue use and dispose of in accordance with hazardous waste regulations.
