Abstract:
A method of quenching formaldehyde comprising:(a) providing a composition and an aqueous solution containing formaldehyde, wherein the composition comprises:(i) a first agent capable of reacting with formaldehyde, and(ii) a second agent capable of substantially preventing the first agent from reacting with formaldehyde,wherein, if the composition is contacted with formaldehyde, then the second agent substantially prevents the first agent from reacting with the contacted formaldehyde for a finite period of time, and after the finite period of time, the first agent reacts with the contacted formaldehyde;(b) contacting the composition with the aqueous solution, thereby causing the first agent to react with the formaldehyde in the aqueous solution, and thereby quenching the formaldehyde.
