On reflection, I've changed my mind a bit following some research. Apparently H, it's made by Jeyes Limited, Brunel Way, Thetford, Norfolk, IP24 1HF. Co-incidentally, I drove through Thetford on Sunday and I did wonder why the denizens of that historic market town were walking round like Burgess Meredith, The Penguin in Batman.
Anyhow, I've discovered that it was medicated with San Izal Disinfectant, a powerful phenolic germicide, the ingredients of which are: Aqua, Propylene glycol, Phenoxyethanol, Aloe barbadensis, Polysorbate 20, Myrtrimonium Bromide, Methylparaben, Sorbic Acid, Disodium Cocoamphodiacetate, Disodium Phosphate, Parfum, Laurtrimonium Bromide, Citric Acid, Potassium Sorbate, Sodium Benzoate, Sodium Chloride.
Izal had other features too mind. My Dad once showed me how to make a kazoo out of a sheet of Izal and a comb, and it was used as tracing paper by impoverished artists. But you'll remember it was crap for blowing your nose on.
Basically then, it was a grown up paper for grown up men's arses and we really shouldn't have been given it to use at school, someone would be on an offenders register for that these days. We were rubbing that little lot into our nether regions for years and it's a relic from an age when Craven A was good for your throat. And we wonder why we have this trouble today.
So if you do use it again, remember not to do the first wipe with the shiny side.
