Abstract
Rinse aids and sanitizing rinse aids for various applications, including institutional machine sanitizing are disclosed. In particular, concentrated and use compositions, such as concentrated liquid rinse aid compositions, employing a synergistic combination of a quaternary ammonium compound and anionic surfactant are disclosed. In particular, the present invention provides compositions and methods of a sanitizing rinse providing desired antimicrobial efficacy against a broad spectrum of gram negative microbes, suitable foaming profiles, and beneficial applications of use of the same, including low temperature sanitizing rinse are provided.
Claims6
A concentrated antimicrobial rinse aid composition consisting of:
- about 11 wt. % to about 30 wt. % of an antimicrobial quaternary ammonium compound consisting of a C12-C16 alkyl dimethyl benzyl ammonium chloride, didecyl dimethyl ammonium chloride, dioctyl dimethyl ammonium chloride, octyl decyl dimethyl ammonium chloride, or a combination thereof;
- from about 0.1 wt. % to about 20 wt. % of an anionic surfactant consisting of octanoic acid, decanoic acid, ethylhexanoic acid, lauric acid, or a combination thereof;
- and
- the remainder of the composition is an additional functional ingredient consisting of a thickener, viscosity modifier, solvent, solubility modifier, humectant, metal protecting agent, stabilizing agent, corrosion inhibitor, solidifying agent, sheeting agent, colorant, odorant, perfume, hydrotrope, coupler, defoamer, or a combination thereof;
- wherein the antimicrobial quaternary ammonium compound and the anionic surfactant form a complex without requiring nonionic surfactants, sequestrants, or chelating agents;
- and
- wherein the composition has a pH of 1 to 6.
