-D
I CM-246M2 41-, Z, la HARD-SURFACE CLEANING COMPOSITIONS 7 C C cc Stephen Culshaw Eddy Uos Technical .eld The present invention relates to hard-surface cleaning compositions containing a binary mixture of an organic solvent and a narrowly defined organic chelating agent.
Background of the Invention ~-f
M
It is well known to formulate hard-surface cleaning compositions, containing organic solvents and chelating agents.
European Patent Applications 0 040 882, 0 080 749, 0 126 545 describe the use of solvents represented by mixtures of terpenes with benzyl alcohol or butyl carbitol, together with builders which are mainly polyphosphates, or nitrogen containing strong sequestrants like NTA.
EP 0 105 863 and U.S. Patent 3,591,510 describe the use of certain glycol ether derivatives as solvents in liquid cleansers, together with polyphosphate builders.
The above solvent/builder combinations have proven very effective; however, in recent years phosphates have come S° under scrutiny for environmental reasons, and other non-phosphate strong sequestering agents are also facing acceptability problems related to toxicity/environmental safety.
There is therefore a need for hard-surface-cleaning compositions which are effective and at the same time are not likely to raise safety concerns with regard to toxicology and environment.
S The present invention is based on the discovery that certain known chelating agents, when combined with a specific class of organic solvents, provide very good results in terms of soil-removal from hard surfaces, because of unexpected and beneficial chelant/solvent interaction, said known chelating agents being safe compounds constituted solely of carbon, hydrogen, and oxygen.
Carboxymethyltartronic acid has been described as .i detergency builder in U.S. Patent 3,865,755, and in DE-OS-2 549 741.
Oxydisuccinic acid and carboxymethyloxysuccinic acid are known in the same functionality, from U.S. 3,635,830, and 3,692,685.
3 Tetrahydrofuran tetracarboxylic acid is known as phosphate replacement builder from U.S. 3,580,852.
Diglycolic acid is known as sequestering agent in detergent compositions, from DE-OS 2 150 325.
i All above materials have not found great success as phosphate builder replacement in laundry detergent compositions, since their sequestering power has been considered as too weak.
None of the above detergent compositions encompass hard-surface cleaning compositions, and there has been no I .disclosure of the chelating agents described herein, in i combination with organic solvents according to the present i t i. invention, It has now been surprisingly discovered that the combination of the chelating agents herein with certain organic solvent provide very good results in terms of soil j removal from hard surfaces.
It is therefore the object of the present invention to provide efficient hard surface cleaning compositions containing the combination of a safe chelating agent, and a suitable organic solvent.
Summary of the Invention The iniPntinn relates to hard-surface cleaning compositions containing a binary mixture of or g olvent Shaving a boiling point equal to or e 90 0 C, and an organic chelating aa ontaining neither phosphorous nor -n-i f:.r46 ra h rhpi at-ing ajpnf-c hping qp1pri-Pri From 3a According to the present invention there is provided a hard surface cleaning composition containing from 1% to 20% of organic solvent having a boiling point above 90 0 C, said solvent being selected from the group of glycol ethers and diols having 6 to 16 carbon atoms in their molecular structure or the group of C 6

The non-phosphorous chelating agent The chelating agents for use in the present invention are hydrocarbon compounds which do not contain phosphorous or nitrogen, and where the chelating ability is provided by carboxylate groups.
Although such chelating agents are not considered as strong builders by detergent manufacturers, especially in comparison with phosphate builders, it has been surprisingly discovered that their combination with certain organic solvents leads to excellent soil removal action from hard surfaces.

A type of solvent especially suitable for the compositions herein comprises diols having, preferably from 8 to 12 carbon atoms in their molecular structure. Preferred S1 5 diol solvents have a solubility in water of from about 0.1 to about 20 g/100 g of water at S" 20°C. The most preferred diol solvents are 2,2,4-trimethyl-1,3-pentanediol and 2-ethyl-1,3-hexanediol.
I The glycol ethers may be selected from water-soluble CARBITOL® solvents or S water-soluble CELLOSOLVE® solvents. Water-soluble CARBITOL® solvents are compounds of the 2-(2-alkoxyethoxy)ethanol class wherein the alkoxy group is derived from ethyl, propyl, butyl, pentyl hexyl; a preferred water-soluble carbitol is 2-(2butoxyethoxy)ethanol also known as butyl carbitol. Preferred are also hexyl carbitol and 2-methyl pentyl carbitol. Water-soluble CELLUSOLVE® solvents are compounds of the 2-alkoxyethoxy ethanol class, wherein the alkoxy group is preferably butyl or S 25 hexyl.
Still in the glycol ether category, certain propylene-glycol derivatrives have been found to be particularly efficient in the present context; these species include i -n-butoxypropane-2-ol, and 1(2-n-butoxy-1-methylethoxy)propane-2-ol(butyoxypropoxypropanol), with the latter being especially preferred.
3 0 Mixtures of the above solvents can also be used, like Butyl carbitol and/or Benzyl alcohol together with diols and/or glycol ethers.
The organic solvent is preferably at levels of from 1% to 10% by weight of the total composition.
41 6 Chelating agent/solvent combination The benefits of the present compositions are derived from the combination of the specific organic chelating agents and organic solvents described hereinabove.
They are particularly noticeable in terms of calcium soap-soil removal from surfaces such as bathtub surfaces.
I In order to obtain such an effect, the weight ratio of organic solvent to chelating agent is in the range from 2/3 to 2/1, preferably 1/1 to 2/1.

Other optional ingredients are represented by conventional detergency builders, which may be used in addition to the chelating agent herein; compounds classifiable and well-known in the art as detergent builders include the nitrilotriacetates (NTA), polycarboxylates, citrates, water-soluble phosphates such as tri-polyphosphate and sodium ortho- and pyro--phosphates, silicates, ethylene diamine tetraacetate (EDTA), amino-polyphosphonates (DEQI'EST), phosphates and mixtures thereof.
Highly desirable ingredients for use herein are represented by conventional detergent hydrotropes. Eamples of suitable hydrotropes are urea, monoethanolamine, diethanolamine, triethanolamine and the sodium potassium, I ammonium and alkanol ammonium salts of xylene-, toluene-, I t f t. 1 ethylbenzene- and isopropyl-benzene sulfonates.
The hard-surface cleaning compositions of the invention may also contain an abrasive material.
S 'The abrasives suitable herein are selected from water-insoluble, non-gritty materials well-known in the literature for their relatively mild abrasive properties.
It is highly preferred that the abrasives used herein not be I undesirably "scratchy". Abrasive materials having a Mohs hardness in the range of about 7, or below, are typically used; abrasives having a Mohs hardness of 3, or below, can be used to avoid scratches on aluminum or stainless steel finishes. Suitable abrasives herein include inorganic materials, especially such materials as calcium carbonate and diatomaceous earth, as well as materials such as Fuller's earth, magnesium carbonate, China clay, attapulgite, calcium hydroxyapatite, calcium orthophosphate, dolomite and the like. The aforesaid inorganic materials can be qualified as "strong abrasives". Organic abrasives such as urea-formaldehyde, methyl methacrylate It melamine-formaldehyde resins, polyethylene spheres and i polyvinylchloride can be advantageously used in order to avoid scratching on certain surfaces, especially plastic surfaces.
j Typically, abrasives have a particle size range of 10-1000 microns and are used at concentrations of 5% to l in the compositions. Thickeners are frequently added to suspend the abrasives.
Thickeners will preferably be included in the compositions of the inventions, mainly in order to suspend j the abrasive; high levels of thickener are detrimental to the performance because they are difficult to rinse from the S 'cleaned surfaces. Accordingly, the level will be kept under Ij t preferably from 0.2% to Common thickeners such as i' the polyacrylates, xanthan gums, carboxymethyl celluloses, swellable smectite clays, and the like, can be used herein.
