Abstract
A composition comprises from 0.1 to 30 wt-% of one or more amino acids, 0.1 to 30 wt-% of one or more surfactants, and optionally one or more hydrotropes. The amino acids may be selected from arginine (“ARG”), lysine (“LYS”), histidine (“HIS”), glycine (“GLY”), or combinations thereof. The composition can be formulated as a cleaning composition, such as a hard surface cleaner, a floor cleaner, or a degreaser. The composition can be used in a method for treating a surface, where the composition is applied to the surface and allowed to remain on the surface for a length of time, and the surface is then wiped.
Claims6
A method of removing soil from a hard surface, the method comprising:
- a. applying a cleaning composition to a soil on the hard surface, the cleaning composition comprising:
- i. about 0.1 to 8 wt-% lysine,
- ii. about 15 to 40 wt-% anionic surfactant comprising an alkyl benzene sulfonic acid and a xylene sulfonic acid, or salts thereof, present in a ratio of at least 3 parts of alkyl benzene sulfonic acid for every part of xylene sulfonic acid,
- iii. about 0.3 to 2 wt-% an inorganic magnesium salt selected from the group of magnesium chloride, magnesium nitrate, magnesium sulfate, and magnesium oxide,
- iv. water, and
- v. from about 0.5 to about 20 wt-% organic solvent,
- wherein the composition is free of an alkanolamine and wherein the inorganic magnesium salt is present in no greater than 1 part of magnesium for every part of the anionic surfactant on a molar basis;
- b. allowing the cleaning composition to remain on the hard surface for a length of time;
- and
- c. removing the cleaning composition and soil from the surface.
