Surface disinfectant with residual biocidal property
A disinfectant formulation is provided imparting a residual biocidal property. The disinfectant formulation is used to treat a surface to impart a film having a capacity to quickly kill bacteria and other germs for at least 24 hours after deposit of the film on a treated surface. The disinfectant formulation comprises a polymer binder, wherein the polymer binder is an oxazoline homopolymer or an extended or a modified polymer based on an oxazoline homopolymer, and a biocidal compound. The disinfectant formulation further comprises a carrier. An article having the disinfectant formulation is provided as well as methods of making, using and applying the disinfectant formulation.
1. A disinfectant formulation imparting a residual biocidal property, the disinfectant formulation comprising:
0.2 weight % to 3 weight % of an oxazoline homopolymer having a structure of:
wherein
R 1 is hydroxyl,
R 2 is hydroxyl,
R 3 is alkyl and
n is in a range of 10 to 1,000,000;
0.2 weight % to 4 weight % of a quaternary ammonium compound having a structure of:
wherein
R 1 is methyl;
R 2 is C 8 -C 12 alkyl, or benzyl;
R 3 is methyl;
R 4 is C 8 -C 16 alkyl;
X − , an anion, is Cl;
and a carrier.
2. The disinfectant formulation according to claim 1 , wherein the disinfectant formulation is in a form of a liquid.
3. The disinfectant formulation according to claim 1 , wherein the carrier comprises a solvent or a mixture of solvents.
4. The disinfectant formulation according to claim 3 , wherein the solvent is selected from the group consisting of water, a low molecular weight alcohol, alkylene glycol ether, a terpene or terpene derivative, and a combination thereof.
