Definitions
- the present invention relates to hard surface cleaning compositions.
- the compositions herein are specifically designed for the safe cleaning of marble, painted and lacquered surfaces, especially lacquered and painted wood.
- marble and lacquered surfaces are two types of surfaces which do require particular attention, when formulating cleaning compositions for their cleaning.
- marble is mainly composed of calcium carbonate, and is therefore incompatible with cleaning compositions which would be acidic, and/or which would comprise a builder.
- acidity would "dissolve” marble
- the builder whose function is specifically to bind ions which are present in water and dirt particles, would also bind the calcium in the marble, thereby turning the surface from very shiny to dull, as the introduced surface irregularities lower the reflectance of the surface.
- cleaning products formulated at neutral pH and which contain anionics surfactants also damage marble, probably because the anionic surfactants would also bind the calcium in the marble as described hereinabove.
- the formulation of an alkaline composition free of anionic surfactants would seem indicated in the present circumstances.
- an alkaline composition does not accommodate the cleaning of lacquered and painted surfaces, such as painted metal surfaces, or lacquered and painted wooden surfaces e.g. lacquered wooden floors.
- lacquers are typically made out of polyurethanes or polyacrylates or mixtures of both, and paint is mainly pigmented polyacrylates, polyvinylacetates or alkydresins. Indeed such surfaces are permanently damaged by alkalinity. Specifically, alkalinity would destroy the lacquer and therefore give the lacquered surface the appearance of dullness or a colour change. Thus it would appear that formulating a cleaning composition which is suitable for cleaning both marble and lacquered surfaces is hindered by incompatible pH requirements.
- a liquid composition which is suitable, i.e. safe, for the cleaning of both marble and lacquered surfaces, and which comprises an anionic surfactant so as to provide good cleaning performance, in particular which performs well on grease removal.
- a liquid composition which comprises at least one anionic surfactant, which is free of strong builders, which is formulated at a mildly acidic to mildly alkaline pH, and which comprises positive divalent ions in amounts so as to saturate the anionic surfactant in the composition.
- the mildly acidic to mildlly alkaline pH damages neither marble nor lacquers.
- the positive divalent ions in a saturating amount for the anionic surfactant prevents the damage on marble, while still allowing the anionic surfactant to perform its cleaning action.
- the present invention encompasses a liquid cleaning composition which comprises at least one anionic surfactant, which is free of strong builders, which is formulated at a mildly acidic to mildly alkaline pH, and which comprises positive divalent ions in an amount so as to saturate the anionic surfactant in the composition.
- the present invention further encompasses a method of cleaning marble or lacquered surfaces, where an effective amount of said composition is applied to clean said marble or lacquered surfaces, and said composition is removed.
