Abstract
Disinfectant/sanitizer solutions contain aldehyde, surfactant, a quaternary ammonium compound, a main solvent and a co-solvent. Clear disinfectant/sanitizer solutions are made by adding the components of the solutions in a certain order and mixing them together. Concentrated disinfectant/sanitizer solutions can be diluted prior to being applied to a hard surface. Disinfectant/Sanitizer solutions are in the form of a liquid or spray. Liquid disinfectant/sanitizer solutions may be applied to a hard surface using a wipe impregnated or wetted with the solutions.
Claims21
A disinfectant/sanitizer solution comprising by weight percentage of the disinfectant/sanitizer solution of:
- (a) from about 1% to about 50% of a quaternary ammonium compound having the following general formula (I):
- R1R2R3R4N+X−
- wherein, R1, R2, R3 and R4 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 R1, R2, R3 and R4 has at least eight carbon atoms and wherein X− represents an anion;
- (b) from about 0.1% to about 25% of an aldehyde;
- (c) from about 0.1% to about 30% of a surfactant selected from:
- nonionic surfactant, cationic surfactant and combinations thereof;
- (d) from about 30% to about 90%, from about 34% to about 89%, from about 40% to about 80% or from about 50% to about 75% of a Main Solvent;
- and
- (e) from about 0.5% to about 40%, from about 1% to about 30% or from about 2% to about 20% of a Co-Solvent.
A method of making a disinfectant/sanitizer solution, the method comprising:
- (a) adding to a mixing vessel in the following order:
- a Main Solvent, a Co-Solvent, an aldehyde and a surfactant, and stirring them together;
- (b) adding a quaternary ammonium compound to the mixing vessel, the quaternary ammonium compound having the following general formula (I):
- R1R2R3R4N+X−
- wherein, R1, R2, R3 and R4 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 R1, R2, R3 and R4 has at least eight carbon atoms and wherein X− represents an anion;
- and
- (c) stirring until a clear disinfectant/sanitizer solution is generated in the mixing vessel.
A disinfectant/sanitizer solution comprising by weight percentage of the concentrated disinfectant/sanitizer solution:
- (a) from about 5% to about 20% of a quaternary ammonium compound having the following general formula (I):
- R1R2R3R4N+X−
- wherein, R1, R2, R3 and R4 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 R1, R2, R3 and R4 has at least eight carbon atoms and wherein X− represents an anion;
- (b) from about 2% to about 15% cinnamaldehyde;
- (c) from about 2% to about 10% of a surfactant selected from:
- nonionic surfactant, cationic surfactant and combinations thereof;
- (d) from about 50% to about 75% water;
- and
- (e) from about 2% to about 20% of a Co-Solvent selected from:
- ethers;
- alcohols;
- glycols;
- glycol ethers, glycol ether acetates, glycol diethers;
- polyols;
- hydrogels;
- and combinations thereof
- wherein the disinfectant/sanitizer solution is clear.
