Definitions
- the present invention relates to compositions for cleaning hard-surfaces, especially in-house hard-surfaces.
- compositions for cleaning hard-surfaces have been disclosed in the art. Much of the focus for such compositions has been on providing outstanding cleaning on a variety of surfaces and soils. For some specialised cleaners, such as glass cleaners, much effort has additionally been devoted to the formulation of so-called "streak-free" products, i.e. products which leave no or little visible residues after use.
- the object of the present invention is to formulate hard-surface cleaning compositions which clean and provide gloss to the cleaned surface. That is different from a "streak-free" composition, in that gloss additionally requires improved reflectance of light from the cleaned surface.
- a variety of products are commercially available for delivering gloss to surfaces, and they are disclosed for instance in US 3,960,575 and US 4,218,250. Both references recommend the use of various silicones for delivering gloss.
- Such compositions are not fully formulated hard-surface cleaners, so that they do not clean efficiently, and indeed the formulation of silicone in hard-surface cleaners has not shown any gloss benefits. See for instance EP 374 471 which discloses a hard-surface cleaning composition with, amongst other essentials, a silicone for improved resistance to soil redeposition.
- compositions may be used to clean in-house hard-surfaces made of a variety of material like glazed and non-glazed ceramic tiles, vinyl, linoleum, melamine, both in diluted and neat conditions.
- US 4784 786 discloses a composition for cleaning glass which can be readily applied to and removed from a soiled glass surface to leave the surface clean and free of streaking and cloudiness.
- Said compositions comprise amongst other ingredients, surfactants, glycol ether, an anionic polysulfonic acid and an anhydride compound comprising an olefin-maleic anhydride copolymer. No divalent counterions are disclosed.
- WO 94/26858 discloses a liquid hard-surface composition (pH 2-8) with nonionic surfactants (1-30%) and anionic polymers having an average molecular weight of less than 1 000 000. Said compositions bring a surprising initial cleaning benefit in addition to the anti-soiling benefit. Indeed, WO 94/26858 discloses that acrylic, methacrylic and maleic anhydride derivatives such as copolymers of styrene with maleic produce a streak-free finish after drying. No divalent counterions are disclosed.
- EP-A-658 184 discloses liquid or gel dishwashing detergent compositions containing alkyl amphocarboxylic acid (5%-95%) and magnesium or calcium salts (0.1%-4%), said compositions having a pH in a 10% solution in water at 20°C of 7 to 10.
- said compositions comprise co-surfactants, like nonionic surfactants (5%-95%).

- EP-A-162 033 further discloses that the level of calcium ions should be selected so that there is always some minimum level available for the enzyme, after allowing for complexation with fatty acids and the like in the composition.
- Sources of calcium ions are for example calcium chloride and/or calcium acetate. No hard-surface application is disclosed.
- EP-A-602 179 discloses that the addition of calcium salts to compositions containing a polyhydroxy fatty acid amide, and an anionic surfactant improves the removal of greasy soils while delivering good hand mildness.
- EP-A-602 179 discloses dishwashing compositions comprising an anionic surfactant (3%-95%), a polyhydroxy fatty acid amide (3%-40%) and calcium ions (0.1% to 3%).
- the compositions have a pH of from 5.5 to 10 in a 10% solution in water at 20°C.
- said compositions comprise polycarboxylate polymers having a molecular weight of 750 000 to 4 000 000 (0.1%-10%). No hard-surface cleaning application is disclosed.
- EP-A-670 884 discloses fully formulated liquid detergent compositions (pH 7.5-9.5) comprising a polyhydroxy fatty acid amide surfactant (5%-50%), a nonionic (5%-50%), a source of calcium (0.5%-2%) and soap.
- Optional ingredients are polycarboxylate builders such as copolymers of maleic anhydride with ethylene or vinyl methyl ether and polymeric polycarboxylic dispersing agents (0.1%-7%) that can be prepared by polymerizing or copolymerizing suitable unsaturated monomers including acrylic acid, maleic acid.
- Acrylic/maleic-based copolymers with a molecular weight of 2 000 to 100 000 are disclosed. No hard-surface application is disclosed.
- GB 1430 204 discloses compositions suitable to clean various soiled subtracts including hard-surfaces.
- Said compositions comprise a polymer (3%-35%) such as acrylic polymers and polycarbonates, optionally metal ions such as calcium or magnesium (0.1%-5%), and builders (0.1%-5%) such as copolymers of vinyl methyl ether and maleic anhydride, and carboxymethyl cellulose.
- a surfactant may be used as optional but no levels thereof are disclosed, let alone particular classes of surfactants.
- GB 1430 204 also discloses a process of cleaning a soiled surface, said process comprising the steps of applying to said surface said composition, allowing said composition to form a tacky film to which soils adhere, allowing said composition to dry, whereby as a result of said drying, said film fractures to form a removable residue and then removing said residue.
- the presence of the metal ions increases the brittleness of the film.
