astor,
If it is oilatum, you can be rest assured as it does not have tar... the major ingredients of it should be something called parrafin (or white parrafin). Are you using the one with 消毒成份 or the plain bathing gel. If it is plain bathing gel, it is using the same ingredients used in Aqueous Cream and Emulsifying Ointment. Matthew and Muichu used to use oilatum, but I switched to Emulsifying Ointment when the weather becomes so dry that even Oilatum cannot help. It works. Besides, Emulsifying Ointment is much cheaper than Oilatum.
