Dehydrated Castor Oil
Dehydrated Castor Oil (DCO) is a unique drying oil derived from castor oil through a dehydration process. Here are some key details: Unlike castor wax, which is created through hydrogenation, Dehydrated Castor Oil (DCO) is produced by removing moisture from castor oil. The process starts with extracting castor oil from the seeds of the Ricinus communis plant. The oil is then carefully heated under controlled conditions to remove water, which changes the molecular structure, enhancing its stability and reducing its susceptibility to oxidation. Catalysts are employed to speed up the dehydration process, ensuring the oil maintains its essential properties while increasing its concentration.
