Storage & Handling

Shelf Life
12 months
Preservative System

COSMACOL AES-27-2-24 NE is supplied containing a small amount of preservative sufficient for transport and short term storage. If the product is stored for several weeks or months it is necessary to carry out regular check of microbial content. Furthermore careful precautions like clean sampling vessel, sterilized water for dilution, limit prolonged or too often repeated exposure to open air, etc. are necessary to maintain microbiological purity of the product.

Storage and Handling

COSMACOL AES-27-2-24 NE should be stored preferably in stainless steel or fiber glass tanks.

COSMACOL AES-27-2-24 NE must be stored at temperature below 40°C. Temperature above 45°C should be avoided, even briefly, because hydrolysis may occur with formation of sulphuric acid. Storage tanks must be heated with water warmed at a temperature below 50°C. The use of steam to warm up the product is absolutely prohibited. In addiction contact with acids could cause hydrolysis as well.

COSMACOL AES-27-2-24 NE is a clear liquid at room temperature and it can be easily pumped.
