How to store Lubailin/O-8? What is the shelf life?

Lubailin/O-8 should be stored in a cool, dry, and well-ventilated place, strictly sealed to prevent moisture. The shelf life is subject to the product label (typically 1-2 years under normal conditions), and a first-in, first-out management policy should be implemented.

Detailed Description

Lubailin/O-8 (Fatty alcohol polyoxyethylene (8) ether, CAS: 68439-49-6) is a nonionic surfactant, appearing as a milky white to light yellow paste with hygroscopic properties. Therefore, moisture-proof sealing during storage is key to ensuring product quality. The product exhibits excellent chemical stability in acids, alkalis, and high-concentration electrolyte salt solutions, but temperature and humidity control in the storage environment directly affect the maintenance of its appearance and performance.

According to the official safety data requirements of Guoli Chemical, the warehouse temperature should not exceed 30°C, and relative humidity should not exceed 75%. Containers must remain sealed to avoid moisture absorption, which could cause the paste to soften or reduce effective content. At the same time, keep away from fire, heat sources, and direct sunlight to prevent color deepening or performance degradation under high-temperature conditions.

Regarding shelf life, the database does not specify a specific duration; it shall be subject to the product label, and the first-in, first-out principle should be strictly followed. Referring to industry practices for similar fatty alcohol polyoxyethylene ether products, under the above storage conditions, the shelf life of unopened original packaging is typically 1 to 2 years. It is recommended that users check the production batch number and expiry date on the packaging drum upon receipt, and prioritize products approaching their expiry date.

Storage Conditions Overview

Application Recommendations

• Post-opening management: Immediately reseal the container after use to minimize product exposure to moisture in the air, preventing surface moisture absorption and clumping of the paste.
• Winter storage: The product's congealing point is about 10~15°C. At low temperatures, the paste will solidify and harden; this is a normal physical change. Before use, warm the drum in an ambient environment to natural temperature and stir evenly to restore performance without affecting product quality.
• First-in, first-out: Establish an inventory ledger and strictly implement the first-in, first-out management policy based on production batch numbers and arrival dates to avoid expiration during storage.

Precautions

• Handle with care during transportation to prevent damage to packaging drums, which could cause leakage or moisture absorption.
• Keep away from fire and heat sources; smoking is strictly prohibited in the work area. The product has a flash point above 150°C but is still a combustible chemical.
• In case of spillage, absorb small amounts with sand or vermiculite; for large spills, build a containment dike to collect the material, and do not discharge into sewers or water bodies (harmful to aquatic life with long-lasting effects).
• Operators in the storage area should wear protective gloves and goggles to avoid skin and eye contact.
