Not wishing to jump the gun here but "the moon is made of green cheese"
Just because it has been written by you does not make it true. So Cogs, can you please supply your source for the statement that Latex gloves are not a barrier. data sheets that I have read relating to for example Aeroshell 560, do state that organophosphates are present but state that impervious gloves should be worn. If you are wearing latex gloves while handling this oil and after removing the gloves there is no oil underneath them how can the oil have penetrated your skin??
If you can provide a credible source we can act on the information. We need data not rumour!.
