I am advised by the makers of Chemical sponges that whilst they told
me the product was a natural composition it does in fact contain
some traces of soap. Apparently the inclusion of soap, albeit in a
miniscule proportion (approximately 1 ounce to every 1000 pounds of sponge
manufactured) is designed to improve the containment properties.

My apologies to one and all for the misleading information supplied,
it was provided in good faith after talking with the makers.

Interestingly the makers also told me that the product relaunched
with the words 'chemical treated' actually ensured improved sales,
users apparently felt that it must clean better as a result.

The product does however contain no other chemical products.
