NEFCHEM LCS116 is a liquid laundry sour with chlorine and alkali neutralizing power. This product performs dual function of neutralizing the alkali and residual chlorine in a single step wash process. It is an optimized formulation and even the excess dosage by accident will not lower the pH to an extent that it will damage the fabric. It prevents the yellowing (galling) of the fabric due to residual alkali left on the fabric and chlorine left during the wash cycle. It is based on bisulphite, which are very mild acidic solution and is used in the final rinse. These are also called antichlor.
