Isooctanol Penetrant OE-35 (CAS No.: 68439-51-0) is a nonionic surfactant with isooctanol polyoxyethylene ether as the active ingredient. It is hygroscopic and has a melting point below -10°C. To ensure stable product quality, the following storage requirements must be strictly followed:
The ambient temperature should be controlled within 5–35°C, away from fire, heat sources, and direct sunlight. The warehouse should be kept dry, cool, and well-ventilated. After opening, the product must be resealed immediately to avoid prolonged exposure to humid air leading to moisture absorption and deterioration. Additionally, protect from freezing under extremely low temperatures.
The packaging materials are 50kg plastic drums, 200kg plastic drums, or IBC totes. It should be kept in original sealed condition. This product has good chemical stability (stable under normal conditions), but must be stored separately from incompatible substances such as strong acids and strong oxidizers to prevent accidental reactions. It is recommended to equip the storage area with leak-proof trays or secondary containment. Empty containers should also be disposed of properly.
| Parameter Name | Parameter Value | Remarks |
|---|---|---|
| Appearance | Colorless to slightly yellow | Liquid |
| pH value (1% aqueous solution) | 5.0~7.0 | Nearly neutral, non-corrosive to packaging materials |
| pH value (5% aqueous solution) | 5.0~7.0 | |
| Moisture content | ≤0.5% | Low moisture ensures storage stability |
| Melting point | <-10°C | Not easy to freeze or solidify even at low temperature |
| Flash point | >200°C | High flash point, not flammable at room temperature |
| Hygroscopicity | Hygroscopic | Must be sealed to protect from moisture |
| Chemical stability | Stable under normal conditions | No decomposition under normal storage |
The product database of Guoli Chemical has not yet provided the exact shelf life data for Isooctanol Penetrant OE-35. According to industry common practice, such nonionic surfactants (fatty alcohol polyoxyethylene ethers) under recommended storage conditions (sealed, protected from light, 5–35°C) can usually be stably stored for more than 12 months, and some products can maintain qualified performance for up to 24 months.
The actual shelf life is affected by various factors such as transportation process, storage temperature fluctuations, container sealing, etc. To ensure the effectiveness, it is recommended that users:
