Storage & Handling

Storage and Handling

The product should be stored in a cool, dry and ventilated area in tightly closed containers below 40℃, protected from light and moisture. If the product is stored at a low temperature it may turn cloudy, solidify or form layers. It is therefore advisable to heat and thoroughly mix the contents of drums or containers before using in order to obtain a homogeneous product.

Surfactant has hygroscopicity, after opening the container, product quickly absorbs moisture from the environment, air will enter the container at the same time, it may result in the slow oxidation of products, and could eventually cause deep color or decreased pH value. So, drums or containers should be kept sealed and stored in a cool, dry place.

In above storage situations, for material in original, unopened, properly stored containers, the shelf life is two years from the production date.
