Abstract (en)

[origin: WO9734834A1] Water clarifying compositions which are blends of one or more polymeric cation compounds and hydrogen peroxide. The polymeric cations are preferably polyquaternary ammonium compounds such as Q6/6, Q12/6, Q4/6 or PDED, or a cationic polymer such as PHMB. Combinations of two or more immiscible polymers may be preblended with concentrated hydrogen peroxide to provide shelf-stable, preblended compositions that may be applied as a single-dose product.
