How to Store Refined Glycerine Properly

Properly storing bulk glycerine guarantees that the product stays pure and effective for a long time. Below are the tips on how to do so.

Keep It in a Cool and Dry Area

Glycerine should be stored in a location that is neither too hot nor too cold. The area should remain at a stable temperature. Both extreme heat and cold can affect the glycerine's viscosity and overall quality. Therefore, it is best to store the chemical in a climate-controlled environment that is cool, dry, and free from direct sunlight.

Hydration

Since glycerine is highly hygroscopic, it will readily absorb moisture from the surrounding air. This is even if it is just a little bit. That is why it is vital to keep it inside a sealed, airtight container. Doing this prevents moisture absorption and guarantees that glycerine maintains its intended purity levels. It will also ensure that there is no leakage when transporting the chemical.

Keep It Away from Contaminants

Refined glycerine is susceptible to contamination from various substances. These substances include chemicals, heavy metals, and any materials that may have been in touch with it. That is why it is important to store glycerine away from such items. Also, ensure that the storage container is in good condition to avoid contamination with any residue on the container.

Regularly Check for Signs of Damage

If the glycerine is in a drums or any other type of equipment, the buyer should frequently check for any cracks, rust, or leakage. Doing this will guarantee that the glycerine remains safe and continue to be effective for a long time. Also, if there are any warning signs of the drum break or any other storage equipment leaking, it is important to fix them immediately.

Monitor Temperature and Humidity

Since temperature fluctuations can affect glycerine’s viscosity, it is important to regularly check them. Furthermore, humidity levels should also be kept within a reasonable range to prevent glycerine's hygroscopic nature from affecting its quality. Roughly a 20-degree temperature variation or a more significant humidity fluctuation is acceptable. However, try to avoid such occurrences if possible. Otherwise, just ensure that the environment where the glycerine is stored experiences neither extreme heat nor cold.
