Abstract
The disclosure relates to low foam cleaning compositions comprising quaternary ammonium compounds, as well as, methods of manufacturing and methods of using the low foam cleaning compositions. Beneficially the cleaning compositions are compatible with cleaning methods and apparatuses requiring low foam, including, but not limited to, machine warewash and clean-in-place. The cleaning compositions are particularly suitable for low temperature sanitizing applications.
Claims15
A cleaning composition comprising:
- from about 5 wt-% to about 40 wt. % of a quaternary ammonium compound;
- a polycarboxylic acid, sodium xylene sulfonate, and/or salt or mixture thereof with a concentration of about 5 wt-% and about 50 wt-%;
- wherein the polycarboxylic acid has at least two pKa values between about 2 and about 6;
- and
- wherein the composition is a concentrate and upon dissolving provides a log reduction of at least about 6 after a contact time of 30 seconds of contact time to S. aureus;
- and
- wherein the composition has a pH range of 5 to 9;
- wherein the composition is a solid and comprises one or more solidification aids present in a concentration of between 10 wt. % and about 80 wt. %;
- wherein the solidification aid comprises sodium chloride, a starch, a sugar, a C1-C10 alkylene glycol, a solid PEG, a solid PPG, a solid EP/PO, an amide, urea, an acetate, a borate, a phosphate, a silicate, a sulfonate, or a mixture thereof;
- and wherein the solidification aid comprises less than 0.5 wt-% sulfate;
- wherein the composition is free of alkyl polyglycoside.
