Abstract
Hard surface, in particular glass, cleaners having an ease in wipe-out while providing good cleaning with a streak-free, glossy shine are described. The cleaner includes at least one fluorosurfactant including a fluorinated functional group with 2 to 6 carbon atoms, and a hydrophilic moiety; at least one non-fluorinated surfactant; a combination of solvents; a combination of cleaning agents; and water.
Claims10
A hard surface cleaner consisting of
- (a) about 0.001 to about 0.5 wt. % of at least one fluorinated surfactant having a fluorine-containing moiety having a formula of either linear or branched (1) F(CF2)n where “n” is 2-6 or (2) (C2F5)3, and a hydrophilic moiety;
- (b) a plurality of solvents of greater than 0 to about 7 wt. % of at least one C1-C3 alkanol, greater than 0 to about 5 wt. % of at least one ethylene glycol C1-6 alkyl ether, and greater than 0 to about 5 wt. % of at least one propylene glycol C1-6 alkyl ether;
- (c) a plurality of cleaning agents of greater than 0 to about 6 wt. % of at least one mono- or di-alkanolamine having a C1-3 carbon chain, and greater than 0 to about 5 wt. % of at least one ammonium, sodium or potassium hydroxide;
- (d) greater than 0 to about 5 wt. % of at least one anionic alkane or aromatic sulfonate or sulfate;
- (e) a balance to 100% of water;
- (f) optionally, a solubilizer;
- and
- (g) optionally, a fragrance and/or colorant;
- wherein said cleaner has a volatile organic content (VOC) of 3 or less, and is able to remove greasy soil and be removed from a surface treated with the cleaner without leaving a residual haze on the surface.

- about 1.9 to about 2.1 wt. % of isopropanol;
- about 0.15 to about 0.35 wt. % of propylene glycol propyl ether;

- about 0.4 to about 0.6 wt. % of isopropanolamine;
- about 0.2 to about 0.4 wt. % of ammonium hydroxide;
- about 0.1 to about 0.4 wt. % of alkali metal alkane sulfonate;
- a balance to 100 wt. % of water;
- and
- optionally, one or more of a solubilizer, fragrance and colorant;
- wherein said cleaner has a volatile organic content (VOC) of 3 or less, and is able to remove greasy soil and be removed from a surface treated with the cleaner without leaving behind a residual haze on the surface.
