Hi Guys ,

Another one of the 'Holy Grail' topics so I 've got my tin hat on .

Here goes.

Some reading I have done suggests that Woolsafe accreditation is based on the level of alkalinity in a cleaning solution , as measured by titrating with a known acid solution.

Does anyone know if any practical testing is carried out , or if any practical testing was originally carried out to set the benchmark.

If it is only a titration this is a simple process which any lab technician could do and would presumambly save manufacturers a fortune .

Cheers,

Doug

I can only comment on some recent testing that was completed for one of our products, following the standard test as this was a "new" chemical, a series of dye bleed tests were carried out on 70 different type of wool carpet. the test proved the chemical was acceptable and able to carry the Woolsafe logo.

Products are tested for pH alkalinity and for the prescence of any oxidasation properties,

Woolsafe carried out extensive test in varification in testing before deciding on the actual methods of testing, to evaluate the correlation between Ph, Alkalinity, colour fastness, as associated in cleaning.

I would suggest for more information on the Woolsafe oganisation

www.woolsafe.org

Hope this helps

Nick,

Thanks for that , looks like I was doing Woolsafe a disservice.

Cheers,
