(B) consists of 2-60% NaHCO3; 0-6% NaCl, KCl, MgCl2, MgSO4, Na2SO4 or K2SO4; 2-60% humectant (II); 0.1-5% thickener stabiliser (i.e. cellulose gum and/or Mg/Al silicate); 1-30% stabiliser-polishing agent (i.e. bentonite, TiO2, SiO2 and/or MgO) and purified water. (II) is glycerin, sorbitol, polyethylene glycol, polypropylene glycol and/or ethoxylated or propoxylated lower fatty alcohol. The two components are mixed immediately before use. Alternatively component (A) can comprise (i) 0.1-10% H2O2; 0.05-5% (I); 2-80% polyol and water, or (2) 2-25% urea peroxidase; 0-5% (I) and the balance glycerin.
