At one of the tanneries, trials were carried out to test a concentrated washing-degreasing agent for raw wool washing - SN-Sh1R. The trials were made in accordance with the factory recipe. The result is positive: the content of residual fat was in the range of 0.6 - 0.85 %, which corresponds to the norm and the colour of the washed wool corresponded to the factory standard. The product meets the requirements of the factory and is not inferior in degreasing properties at the same concentrations to a similar competitive product. At the moment the factory is carrying out extended industrial tests of this product.
