Abstract

Claims (15)

1 . A concentrated micellar disinfectant/sanitizer solution consisting of, by weight percentage of the concentrated disinfectant/sanitizer solution:

(a) from about 1% to about 50%, by weight, of a quaternary ammonium compound having the following general formula (I):

R 1 R 2 R 3 R 4 N+X−

wherein, R 1 , R 2 , R 3 and R 4 represent independently of each other, alkyl groups, aliphatic groups, aromatic groups, alkoxy groups, polyoxyalkylene groups, alkylamido groups, hydroxyalkyl groups, aryl groups, and H + ions, each with from 1 to 22 carbon atoms, with the proviso that at least one of the groups R 1 , R 2 , R 3 and R 4 has at least eight carbon atoms and wherein X − represents an anion;

(b) from about 0.1% to about 20%, by weight, of cinnamaldehyde;

(c) from about 0.1% to about 30%, by weight, of a surfactant selected from: nonionic surfactant, cationic surfactant and combinations thereof;

(d) from about 50% to about 75%, by weight, of a main solvent, wherein the main solvent is water;

(e) from about 0.5% to about 40%, by weight, of a co-Solvent selected from: ethers, alcohols, glycols, glycol ethers, glycol ether acetates, glycol diethers, polyols, hydrogels, and combinations thereof; and

optionally,

(f) one or more stability enhancers selected rom: radical scavenger, pH adjuster and combinations thereof; and

wherein the concentrated disinfectant/sanitizer solution is clear.

2 . A ready-to-use disinfectant solution comprising one ounce of the concentrated disinfectant/sanitizer solution of claim 1 that has been diluted with 128 ounces of water.

3 . A ready-to-use sanitizer solution comprising one ounce of the concentrated disinfectant/sanitizer solution of claim 1 that has been diluted with 256 ounces of water.

4 . The concentrated disinfectant/sanitizer solution of claim 1 , said surfactant comprising an HLB value of from about 8 to about 60.

5 . The concentrated disinfectant/sanitizer solution of claim 1 , said co-solvent being selected from 2 (2-butoxyethoxy) ethanol, polyethylene glycol, propylene glycol, 2-propanol, glycerine, or combinations thereof.
