It is used to make washing soap, metal soap, varnish, ink, welding materials, insulating materials, etc., and is used as a sizing agent for paper and a softener for increasing the adhesion of rubber.
We normally list 2 years as the shelf life in our COA, the real shelf life is actually much longer than 2 years if it's stocked in good condition (bags are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials).
