Excess caustic levels have decreased over time due to improvements in manufacturing techniques. Household laundry bleach is a dilute aqueous solution of sodium hypochlorite (NaClO). Sodium hypochlorite decomposition rate is dependent on the total ionic strength of the product, temperature of the solution, pH, and transition metal content of the solution. When salt is dissolved in softened water, a brine is created; then, when the solution is electrolyzed, the brine forms a sodium hypochlorite solution and hydrogen gas.
