| − | Iodine number or “Iodine absorption value” expresses the percentage of iodine that is absorbed by the wax when treated with a suitable solution of iodine. It indicates the amount of unsaturated fat or wax acids, unsaturated esters, unsaturated hydrocarbons, and unsaturated alcohols inclusive of sterols and resins.[1] | + | Iodine number or “Iodine absorption value” expresses the percentage of iodine that is absorbed by the wax when treated with a suitable solution of iodine.

| − | Several variations of iodine value have been developed, although Hanus method, Wijs method and Hubl method are still widely used. The iodine number is determinated with a “carrier” for the iodine, in which case the solution may be iodine monochloride in glacial acetic acid (Wijs); iodine monobromide in glacial acetic acid (Hanus); or iodine-mercuric chloride in alcohol (Hubl).[1] | + | Several variations of iodine value have been developed, although Hanus method, Wijs method and Hubl method are still widely used.
