Definitions
- the present invention relates to an all purpose or microemulsion cleaning composition containing a methyl ester ethoxylated cosurfactant.
- This invention relates to an improved all-purpose liquid cleaning composition or a microemulsion composition designed in particular for cleaning hard surfaces and which is effective in removing grease soil and/or bath soil and in leaving unrinsed surfaces with a shiny appearance.
- all-purpose liquid detergents have become widely accepted for cleaning hard surfaces, e.g., painted woodwork and panels, tiled walls, wash bowls, bathtubs, linoleum or tile floors, washable wall paper, etc..
- Such all-purpose liquids comprise clear and opaque aqueous mixtures of water-soluble synthetic organic detergents and water-soluble detergent builder salts.
- the present invention provides an improved, microemulsion liquid cleaning composition having improved interfacial tension which improves cleaning hard surface and is suitable for cleaning hard surfaces such as plastic, vitreous and metal surfaces having a shiny finish, oil stained floors, automotive engines and other engines. More particularly, the improved microemulsion cleaning compositions exhibit good grease soil removal properties due to the improved interfacial tensions, when used in diluted form and leave the cleaned surfaces shiny without the need of or requiring only minimal additional rinsing or wiping. The latter characteristic is evidenced by little or no visible residues on the unrinsed cleaned surfaces and, accordingly, overcomes one of the disadvantages of prior art products.
- This invention generally provides a stable, microemulsion hard surface cleaning composition especially effective in the removal of oily and greasy oil.
- the liquid cleaning or microemulsion composition includes, on a weight basis:
- 0.1 % to 2.5% more preferably 0.15% to 1 % of a fatty acid; 0J to 6%, more preferably 0.2% to 2% of magnesium sulfate heptahydrate;
- compositions do not contain choline chloride, polyethylene glycol, polyvinyl pyrrolidone, or a fully or partially esterified ethoxylated polyhydric alcohol and the composition does not contain a monoester having 8 to 20 carbon atoms which does not contain 6 or 8 ethoxylate groups or an organic diester having 10 to 40 carbon atoms which does not contain 6 or 8 ethoxylate groups such as isohexyl neopentanoate, PEG-8 distearate, PEG-12 distearate, isopropyl myrislate, myreth-3-myristate and laureth-2 (ethyl hexanoate).
- the composition also does not contain a C3-C6 aliphatic carboxylic acid or a glycol ether.
- the present invention relates to a stable microemulsion cleaning composition
- a stable microemulsion cleaning composition comprising approximately by weight: 0.5% to 6%, more preferably 1 % to 3% of a nonionic surfactant containing ethoxylate and or propoxylate groups, 0.1% to 8%, more preferably 1 % to 3% of an anionic surfactant, 0.5% to 8%, more preferably 1 % to 4% of a methyl ethoxylated ester cosurfactant, 0.1% to 2.5%, more preferably 0.15% to 1% of a fatty acid, 0.1% to 5%, more preferably 0.4% to 2% of a water insoluble perfume, essential oil or water insoluble organic compound having 8 to 18 carbon atoms, 0J to 6% of magnesium sulfate heptahydrate, and the balance being water, wherein the composition does not contain choline chloride, polyethylene glycol, polyvinyl pyrrolidone, or a fully or partially esterified ethoxy
- the role of the water insoluble hydrocarbon can be provided by a non-water-soluble perfume.
- a solubilizers such as alkali metal lower alkyl aryl sulfonate hydrotrope, triethanolamine, urea, etc.
- perfume dissolution especially at perfume levels of 1 % and higher, since perfumes are generally a mixture of fragrant essential oils and aromatic compounds which are generally not water- soluble. Therefore, by incorporating the perfume into the aqueous cleaning composition as the oil (hydrocarbon) phase of the ultimate o/w microemulsion composition, several different important advantages are achieved.
- the cosmetic properties of the ultimate cleaning composition are improved: the compositions are both clear (as a consequence of the formation of a microemulsion) and highly fragranced (as a consequence of the perfume level).
- an improved grease release effect and an improved grease removal capacity in neat (undiluted) usage of the dilute aspect or after dilution of the concentrate can be obtained without detergent builders or buffers or conventional grease removal solvents at neutral or acidic pH and at low levels of active ingredients while improved cleaning performance can also be achieved in diluted usage.
- perfume is used in its ordinary sense to refer to and include any non-water soluble fragrant substance or 5 mixture of substances including natural (i.e., obtained by extraction of flower, herb, blossom or plant), artificial (i.e., mixture of natural oils or oil constituents) and synthetically produced substance) odoriferous substances.
- perfumes are complex mixtures of blends of various organic compounds such as alcohols, aldehydes, ethers, aromatic compounds and varying amounts of essential oils (e.g., terpenes) such as from 0% to 80%, usually from 10% to 70% by weight, the essential oils themselves being volatile odoriferous compounds and also serving to dissolve the other components of the perfume.
- the precise composition of the perfume is of no particular consequence to cleaning performance so long as it meets the criteria of water immiscibility and having a pleasing odor.
- the perfume, as well as all other ingredients should be cosmetically acceptable, i.e., non-toxic, hypoallergenic, etc..
- the instant compositions show a marked improvement in ecotoxocity as compared to existing commercial products.
- the perfume in either the microemulsion composition or the microemulsion hard surface cleaning composition at the same previously defined concentrations that the perfume was used in either the microemulsion or the all purpose hard surface cleaning composition one can employ an essential oil or a water insoluble hydrocarbon having 6 to 18 carbon such as a paraffin or isoparaffin.

- compositions of this invention may often and preferably do contain one or more additional ingredients which serve to improve overall product performance.
- One such ingredient is an inorganic or organic salt of oxide of a multivalent metal cation, particularly Mg++.
- the metal salt or oxide provides several benefits including improved cleaning performance in dilute usage, particularly in soft water areas.
- Magnesium sulfate either anhydrous or hydrated (e.g., heptahydrate), is especially preferred as the magnesium salt.
- Good results also have been obtained with magnesium oxide, magnesium chloride, magnesium acetate, magnesium propionate and magnesium hydroxide.
- These magnesium salts can be used with formulations at neutral or acidic pH since magnesium hydroxide will not precipitate at these pH levels.
- compositions can include from 0.1% to 2.5%, preferably from 0.15% to 2.0% by weight of the composition of a C8-C22 fatty acid or fatty acid soap as a foam suppressant.
- the addition of fatty acid or fatty acid soap provides an improvement in the rinseability of the composition whether applied in neat or diluted form. Generally, however, it is necessary to increase the level of cosurfactant to maintain product stability when the fatty acid or soap is present. If more than 2.5 wt.

- up to 4% by weight of an opacifier may be added.
- the final essential ingredient in the inventive microemulsion liquid cleaning compositions having improved interfacial tension properties is water.
- the proportion of water in the microemulsion or all purpose hard surface cleaning composition compositions generally is in the range of 10% to 97%, preferably 70% to 97% by weight.
- the liquid microemulsion cleaning compositions exhibit stability at reduced and increased temperatures. More specifically, such compositions remain clear and stable in the range of 5°C to 50°C, especially 10°C to 43°C.
- Such compositions exhibit a pH in the acid or neutral range depending on intended end use.
- the liquids are readily pourable and exhibit a viscosity in the range of 6 to 60 milliPascal . second (mPas.) as measured at 25°C with a Brookfield RVT Viscometer using a #1 spindle rotating at 20 RPM.
- the viscosity is maintained in the range of 10 to 40 mPas.
- compositions are directly ready for use or can be diluted as desired and in either case no or only minimal rinsing is required and substantially no residue or streaks are left behind. Furthermore, because the compositions are free of detergent builders such as alkali metal polyphosphates they are environmentally acceptable and provide a better "shine" on cleaned hard surfaces.
- liquid compositions When intended for use in the neat form, the liquid compositions can be packaged under pressure in an aerosol container or in a pump-type sprayer for the so- called spray-and-wipe type of application.
- compositions as prepared are aqueous liquid formulations and since no particular mixing is required to form the compositions, the compositions are easily prepared simply by combining all the ingredients in a suitable vessel or container.
- the order of mixing the ingredients is not particularly important and generally the various ingredients can be added sequentially or all at once or in the form of aqueous solutions of each or all of the primary surfactants and methyl ethoxylated ester cosurfactants can be separately prepared and combined with each other.
- the magnesium salt, or other multivalent metal compound when present, can be added as an aqueous solution thereof or can be added directly. It is not necessary to use elevated temperatures in the formation step and room temperature is sufficient.
- compositions explicitly exclude alkali metal silicates and alkali metal builders such as alkali metal polyphosphates, alkali metal carbonates, alkali metal phosphonates and alkali metal citrates because these materials, if used in the instant composition, would cause the composition to have a high pH as well as leaving residue on the surface being cleaned.
