Greying Tests
Ballast soil for redeposition/greying tests
„ Soil makes a difference! “
What is true for stain removal testing is even more true for assessing soil redeposition or rather: whiteness maintenance performance. Existing ballast soil systems with total soil quantities as for single wash tests may be used for such testing, but appear to require too many wash cycles to obtain significant results. An ideal redeposition test system replicates‚ ’real’ greying levels with less wash cycles:
„Accelerate don’t exaggerate!“
For some time now, the detergent industry has been searching for a greying test system that can be used to evaluate greying and whiteness maintenance effects within just a few wash cycles. To find the right solution was a challenge but in cooperation and with the expertise of the member companies of the wfk group we developed some greying donor products.
