Answer

2026-06-06 官方文档十二醇_月桂醇12醇L-23

Dodecanol (lauryl alcohol L-23) should be stored in a cool, dry, and well-ventilated warehouse, keeping the container tightly closed. The storage temperature is recommended to be below 40°C. Under proper storage conditions, the shelf life is usually 12 to 24 months (if the product does not specify a clear shelf life, it is recommended to refer to the product analysis certificate or contact Guo Li Chemical technical support for confirmation).

Detailed explanation

Dodecanol (lauryl alcohol L-23, CAS number: 68439-50-9) is a linear saturated fatty alcohol, appearing as a colorless liquid or white waxy solid at room temperature. The core storage points are moisture prevention, heat prevention, and contamination prevention. Due to the product's high toxicity to aquatic organisms, leakage into sewers or natural water bodies must be strictly prevented during storage.

The product undergoes a morphological change (liquid ⇄ waxy solid) with temperature changes. The storage temperature should be strictly controlled below 40°C to avoid repeated melting/solidification cycles that may cause container deformation or product quality degradation. Meanwhile, the warehouse should use anti-static flooring and grounding systems, use non-sparking tools, and keep away from incompatible substances such as fire, heat sources, and strong oxidizers.

Storage conditions overview

Storage element	Specific requirement
Environment requirement	Cool, dry, well-ventilated warehouse
Temperature requirement	Recommended below 40°C to prevent container deformation caused by melting/solidification
Container status	Keep tightly closed to prevent moisture absorption and impurity ingress
Substances to avoid	Fire sources, heat sources, strong oxidizers, and other incompatible substances
Safety facilities	Anti-static flooring, grounding system, non-sparking tools
Stacking requirement	Do not exceed specified stacking height, leave fire access, equip with fire extinguishing equipment
Environmental requirement	Avoid release into the environment (P273), strictly prohibit discharge into sewers and natural water bodies

Shelf life recommendation

The product database does not specify the exact shelf life of dodecanol L-23. According to chemical industry practices and the stability characteristics of such fatty alcohol products, under strict compliance with the above storage conditions, the recommended shelf life is generally 12 to 24 months. The actual shelf life may vary depending on packaging specifications and storage environment differences. It is recommended:

To follow the shelf life indicated on the product packaging batch label or product analysis certificate (COA)
To regularly inspect the product's appearance, color, odor, and other indicators; stop using if abnormalities are found
To follow the "first in, first out" principle, prioritizing batches with earlier production dates

Precautions

This product is classified under GHS: skin irritation (Category 2), eye irritation (Category 2), acute aquatic hazard (Category 1). Wear protective gloves, protective clothing, and safety goggles during operation.
In case of leakage, immediately absorb with inert absorbent materials (such as sand, vermiculite), collect into a closed container for disposal, and prevent entry into sewers and groundwater.
Waste disposal must be delivered to approved waste treatment plants in accordance with national/local regulations; high-temperature incineration is recommended (P501).
For precise shelf life data, please contact the Guo Li Chemical technical support team to request the product analysis certificate for the specific batch.
