A method to prevent the degradation of water soluble film placed in contact with halogenated hydantoin or chlorinated cyanuric acid and an apparatus for disinfecting water systems. Halogenated 5,5-dialkyl hydantoin or chlorinated cyanuric acid is combined with a stabilizing agent to prevent the halogenated hydantoin or chlorinated cyanuric acid from discoloring or degrading a polymeric film which it may contact. The oxidizing agent includes alkaline hydroxide, alkaline carbonates, alkaline bicarbonates, alkaline phosphates, alkaline silicates, and alkaline borates. Polymeric films for which this is suitable include 2-hydroxy propyl cellulose and poly(vinyl alcohol).
A process for preventing the degradation of a water soluble polymer by halogenated hydantoins, comprising the steps of:
An apparatus for disinfecting water systems, comprising:
In a composition of halogenated 5,5-dialkyl hydantoin covered by a water soluble film, the improvement comprising combining with said halogenated 5,5-dialkyl hydantoin a stabilizing agent selected from the group consisting of an alkaline carbonate, an alkaline hydroxide, an alkaline bicarbonate, an alkaline phosphate, an alkaline silicate, an alkaline borate, and mixtures of these compounds, said stabilizing agent being present in an amount of at most about 5.0 weight % of said composition.
A process for preventing the degradation of a water soluble polymer by chlorinated cyanuric acid, comprising the steps of:
