Abstract
Alkaline sprayable aqueous compositions are disclosed. In particular, sprayable alkaline aqueous chlorine compositions including a surfactant system for modifying the viscosity of the composition, are combined with an alkalinity source and a chlorine source. Methods of cleaning having reduced amounts of airborne particulates of the composition during spray applications are also provided according to the invention, namely reduction of airborne particulates having a micron size of 10 or less within a breathing zone of a user of less than or equal to 60 particles/cm3.
Claims14
A method for reducing inhalation of particulate matter while cleaning a hard surface with a chlorine composition, the method comprising:
- forming an aqueous, ready-to-use, chlorine-based cleaning composition solution, comprising:
- from about 50 wt-% and about 99 wt-% water;
- at least one alkali metal hypochlorite present in an amount between about 0.1 wt-% and about 35 wt-%;
- from about 0.1 wt-% and about 10 wt-% an alkali metal alkalinity source;
- from about 10 wt-% to about 25 wt-% of a surfactant system comprising a first surfactant, a second surfactant and optionally a third surfactant, wherein the first surfactant is an alkyl amine oxide, the second surfactant is a C8-C20 alkane sulfonate, and the third surfactant is a C8-C12 carboxylate, wherein the actives ratio of the first surfactant to the second and optionally the third surfactant is at least about 2.1, and wherein the second surfactant and optionally the third surfactant are present in an amount of at least about 1.75% actives;
- applying the aqueous, ready-to-use, chlorine-based cleaning composition solution to a hard surface for a sufficient amount of time with a trigger sprayer;
- and
- reducing misting and inhalation of particulate matter, wherein the aqueous solution produces a total concentration of misting of particulate matter having a micron size of 10 or less within a breathing zone of a user of less than or equal to 60 particles/cm3.
