Odor control composition and process
View Patent ↗The disclosure of this invention relates to odor control and more particularly, to a process and composition whereby household, institutional and industrial odors are eliminated wherein these odors are incorporated in a variety of substrates or are emitted from industrial sludges, gas side streams, waste water, etc. The odor control composition of this invention is a solution containing active ingredients which will provide or demand active Cl+ donor which may incorporate a suitable wetting agent. The solutions in this invention may further be buffered. The concentration of the Cl+ donor can be from about 0.1 to about 15 weight percent when used. The concentration of the wetting agent can be from about 0.1 to about 5%. The solutions of this invention are effective over a pH range of about 6-14, with a preferred pH range being from 8 to about 9.5. Solutions in accordance with this invention may further incorporate an effective amount of a synergist.
1. A process for controlling odor which is being emitted by a material which incorporates an odorous substance, comprising:
applying a solution containing an effective amount of a Cl+ donor selected from the group consisting of Chloramine B and N-chloro-4-carboxybenzenesulfonamide to the material;
wherein the solution has a pH of from about 6 to about 14 and further comprises an effective amount of low molecular weight alcohol.
2. The process of claim 1 , wherein the concentration of the Cl+ donor is from about 0.1 to about 10 weight percent.
3. The process of claim 1 , wherein the solution is buffered to a pH of from about 8 to about 9.5.
4. The process of claim 1 , wherein the solution is buffered with sodium bicarbonate.
5. The process of claim 1 , wherein the solution further contains a small percentage of a fragrance.
6. The process of claim 1 , wherein the low molecular weight alcohol is t-butanol.
7. The process of claim 1 , wherein the solution further incorporates an effective amount of a wetting agent which essentially does not react with the Cl+ donor.
8. The process of claim 7 , wherein the wetting agent is an anionic or nonionic wetting agent.
