Formula for Non Staining-Iodine ointment
Iodine (5% W/W)
Arachis oil
Yellow soft paraffin
Theory:
Iodine, due to staining, has poor consumer acceptability. When Iodine is combined with Arachis oil, it binds at the double bond present in the free fatty acids, i.e., oleic acid and linoleic acid, to form a non-staining product.
CH3 (CH2)7 CH=CH (CH2)7COOH + I2 ⇌ CH3 (CH2)7CHICHI (CH2)7COOH
