Dodecyl polyoxyethylene ether AC-1205 should be stored in a cool, dry, and well-ventilated dedicated warehouse. The recommended ambient temperature is +5°C to +35°C, protected from light and sealed. The shelf life is typically 2 years (from the date of production, under the recommended storage conditions).

Detailed Description

Dodecyl polyoxyethylene ether AC-1205 (also known as Lauryl polyoxyethylene ether (5EO), CAS No.: 26635-75-6) is a nonionic surfactant with relatively stable chemical properties. However, proper storage is crucial for maintaining product performance and safety. Improper storage may lead to moisture absorption, oxidative deterioration, or corrosion of packaging containers, thereby affecting core properties such as emulsification, dispersion, and wetting.

This product should be stored in a cool, dry, and well-ventilated dedicated warehouse. The ambient temperature is recommended to be maintained between +5°C and +35°C. Strictly protect from moisture and direct sunlight. The warehouse should be kept away from heat sources, ignition sources, and incompatible chemicals (such as strong oxidizers, strong acids, strong bases, etc.), and should be strictly isolated from food and feed. Containers must be kept sealed, with intact and clearly labeled packaging. Any unused material after opening must be promptly resealed to prevent air and moisture from entering.

It is recommended to use stainless steel, polyethylene, or lined protective coating containers for storage. Avoid using fragile glass containers or ordinary carbon steel containers for long-term storage. The storage area should be equipped with leak-proof trays or secondary containment, with impermeable flooring, and should have eyewash stations and emergency shower facilities. It is recommended to regularly inspect containers for any abnormalities such as leaks or swelling. If found, immediately move them to a safe area for handling.

Shelf Life Description

Under strict adherence to the above storage conditions, the recommended shelf life for Dodecyl polyoxyethylene ether AC-1205 is typically 2 years from the date of production. Products beyond the shelf life should not be used directly. It is recommended to perform re-inspection of key indicators such as appearance, pH value, cloud point, and emulsifying power before use. If the product shows signs of obvious color darkening, stratification, off-odor, or turbidity and precipitation, it may have deteriorated. Use should be stopped and the product should be disposed of according to hazardous waste regulations.

Precautions

This product is classified under GHS as Skin irritation (Category 2), Serious eye irritation (Category 2), and Hazardous to the aquatic environment with long-lasting effects (Category 3). The storage area should be equipped with complete safety protection facilities. Operators should wear chemical safety goggles, protective gloves (e.g., nitrile rubber), and appropriate protective clothing when handling. Waste products and contaminated packaging must be managed as hazardous waste. Do not discharge into drains or mix with household waste.
