For · "Cleaning paste with soluble abrasive." ψ J * 4

CLEANING PASTE WITH SOLUBLE ABRASIVE

The present invention relates to the formulation of a stable detergent composition for hard surfaces in the form of a non-pourable viscous cleaning composition, practically free of water, that is to say having a maximum percentage of water of 67 by weight, which comprises a gelled mixture of an organic liquid vehicle consisting essentially of organic solvents and nonionic surfactants containing an ethoxylated fatty acid as an essential component in the in situ gelling of said liquid vehicle, after addition of a small amount from about 0.7 to 1.571 by weight of sodium hydroxide. The addition of ingredients insoluble in the gel, in particular a water-soluble inorganic abrasive adjuvant, to the gelled mixture 15 forms a viscous paste containing a stable suspension of the relatively large particles of said abrasive.

The abrasive is insoluble in the gelled product, but soluble in water. Thus, after using this pasty product to clean a hard surface, the water used to rinse the detergent product dissolves both the gel and the abrasives, and does not leave an ash residue on or around the cleaned surfaces.

The prior art abounds in cleaning products for hard surfaces containing abrasives both in the form of cleaning powders and in liquid form.

Abrasives insoluble in water as major and essential detergent components in cleaning powders are well known, as described in U.5 patent. 3,850,833. However, it has been found that the use of said water-insoluble abrasives in hard surface cleaning powders 5 leaves an unpleasant ash residue on the cleaned surface. This problem has been dealt with in the prior art by replacing all or part of the insoluble abrasive with a water-soluble abrasive, which gives a composition in which the water-soluble components are entrained with the rinsing water, leaving practically no residue on the cleaned surface, as described in U.8 patent. 3,577,347. Another method for dealing with this abrasive residue problem is the use of a water-insoluble abrasive in powder or particulate form having maximum particle sizes less than 0.15 mm, and about BV. by weight of the abrasive particles having a diameter of about 0.037 mm or more for effective cleaning, and a small amount of an organic hydrotropic agent (eg sodium cumenesulfonate) to improve fat removal, such as described in US Patent 4,289.S40.

Similarly, a liquid detergent composition for hard surfaces containing water-insoluble abrasives suspended in an aqueous medium faces the problem of stability as well as the difficulty of completely removing the insoluble abrasive particles from the cleaned surface. These problems have been addressed in the prior art by preparing a high performance liquid detergent composition containing a water soluble builder salt having particles of colloidal size (less than 1 micron and generally 0.1 micron), dispersed in a aqueous medium containing an emulsifying agent Based on a fatty acid amide as described in US Pat. No. 4,057,506. Another means of treating the problem of stability is disclosed in US Pat. No. 3,522,186, where a water-insoluble abrasive dispersed in an aqueous medium containing tetrapotassium pyrophosphate, soda soap, diethanolamide is described. and about 0.25-1.5¾ methanol or ethanol to prevent separation of the aqueous liquid into two layers. Another way to tackle the stability problem is disclosed in US Pat. No. 4,051,055 in which an aqueous detergent composition for a hard surface containing a water-insoluble abrasive is suspended in a thickened aqueous medium with at least 17. d 'clay] 5 as a thickener, said thickened system preventing the separation of the abrasive from the liquid medium. The presence of fluorides increases the ability of the clay-thickened system to keep the abrasive particles in suspension.

US Patent 4,657,632 also describes a thickened aqueous cleaning product, free from syneresis (separation of solids from the liquid), which contains a water-insoluble abrasive suspended in an aqueous medium containing as oxide 25 colloidal alumina, inorganic salts of water-soluble alkali metals such as phosphates, polyphosphates, carbonates, etc., and about 0.5-3% of a surfactant and a halogenated bleaching agent. European Patent Application No. 0193.375 relates to the use of a water soluble salt which functions both as an abrasive and a detergent builder, such as sodium bicarbonate, sodium tripolyphosphate, etc. in a homogeneous, pourable aqueous detergent composition containing an abrasive for cleaning hard surfaces, and t 4 also containing a mixture of anionic and nonionic surfactants in a weight ratio of 1: 1 to 9: 1 of the anionic surfactant to the surfactant non-ionic.

A water-based cleaning agent for hard surfaces in paste form comprising 50-65% sodium bicarbonate and 50-35% by weight of water containing sodium chloride and a fatty acid diethanolamide CCi = -Cls) is described in the US patent

4,179,414.

A water-based gel containing at least 40% anionic surfactant and 2-10% of water-soluble adjuvant salts is described in U.S. Patent 4,107,067 as a laundry detergent composition in the form of a flowable gel.

US Patent 4,257,908 also describes a laundry detergent composition in stable flowable form, containing 25-55% of an adjuvant salt of phosphate type, 5-40% of an anionic surfactant in 30-50% of a aqueous medium containing alcohol according to a water: alcohol weight ratio of 5: 1 to 20: 1.

No. 3,981,826 also describes pasty or gelatinous non-aqueous liquid detergent compositions having cleaning properties and comprising a dispersion of a normally solid water-soluble anionic surfactant of an inorganic salt (adjuvant salt) water-soluble in solid particles and a suspending agent such as very bulky oxides (silica, magnesia, alumina or clay) in about 19-79% of a water-miscible organic liquid solvent such as a polyol (glycerol, ethylene glycol, etc. .), and possibly a lower mono-alcohol (ethanol, methanol, etc.). Another detergent composition for hard surfaces, gelled or grabbed Based on organic solvent, pourable and pourable, is described in US Pat. No. 3,865,756 and comprises a gelling agent which acts as an abrasive such as colloidal silica, alkaline adjuvant salt such as water-soluble phosphates and silicates, a surfactant, a water-insoluble abrasive, eg calcium silicate, and about 55-90% of a cleaning solvent

organic such as a significant amount of a mineral spirits based on aliphatic hydrocarbons mixed with 4-7% of ethylene glycol monobutyl ether. U.S. Patent 2,864,770 also describes a water-soluble aqueous thixotropic liquid detergent composition A

base of organic and pourable solvent which contains glycols and glycerol as organic solvent, an anionic surfactant, and a suspended phosphate adjuvant.

JC

However, none of the above-mentioned patents discloses a viscous, non-pourable detergent composition for hard surfaces, practically free of water, and comprising a gelled mixture of an organic liquid vehicle consisting essentially of water-soluble organic solvents and non-surfactants. -ionics containing an ethoxylated fatty acid as one of the surfactants, and a small amount of sodium hydroxide which reacts in situ with the ethoxylated fatty acid to form a clear non-flowable organic gel, and about 10 & 25% a water-soluble abrasive adjuvant suspended in said gelled vehicle.

It has now been found that the formulation of the new detergent composition of the present invention is based on the ability of ethoxylated fatty acid, especially ethoxylated lauric acid, to react with sodium hydroxide in organic media and form a gel with these media. Another feature of the present new formulation is the incorporation of a water-soluble abrasive material into the organic gelling mixture. This allows the preparation of viscous products containing inorganic solids suspended in a gelled organic vehicle. While this abrasive is insoluble in the gelled vehicle, it becomes soluble by diluting the product with water. Cleaning with the ποη-diluted product is helped by the weak abrasive action of the abrasive, especially sodium pyrophosphate. The overall product dissolves in water, leaving no ash residue on or around the cleaned surfaces. In addition, this abrasive becomes a "surfactant builder" when the product is used diluted. Household surfaces such as ceramic and Formica surfaces can be cleaned with the new products of this invention in the absence or presence of water without scratching the surface. This product, whether undiluted or diluted, has a significantly improved cleaning power due to the triple action of the organic solvent, non-ionic detergent and abrasive. In the diluted product, the abrasive dissolves in water 20 and becomes a detergency builder. The organic viscous product for hard surfaces according to the present invention can function as a sprayed detergent, degreasing cream and multi-use maintenance product for floors and walls. Cleaning tests of simulated floors show that, & 3 g / l of this cleaning product, the result is better than with the "Mr. Clean" product at 15 g / l. This results in the fact that 5 bottles of Mr. Clean equivalent to 1 bottle of this cleaning product.

Accordingly, the primary object of the present invention is to provide a novel viscous organic hard surface cleaner which comprises an ethoxylated fatty acid and sodium hydroxide dissolved in an organic vehicle which reacts in situ to form a gelled vehicle.

7

Another object of this invention is to provide a novel viscous organic cleaning composition containing an inorganic water-soluble particulate abrasive suspended in the gelled organic vehicle.

Yet another object of the present invention is to provide an organic gel containing an abrasive which dissolves in the water leaving no ash residue on or around the cleaned surfaces.

Yet another object of this invention is to provide a multipurpose cleaning product having a triple cleaning action.

Other objects, advantages and new features of the invention will appear partly in the description which follows, and partly in examining the following description or can be taught by practicing the present invention.

In order to achieve the above and other objects according to the present invention, the non-pourable organic gel detergent composition for hard surfaces of the invention contains about 65 to 80% by weight of an organic liquid carrier consisting essentially of about 15 A 35% by weight of a water-miscible organic solvent, about 35 to 70% of a rxri-imicjje surfactant mixture containing an ethoxylated fatty acid as one of the surfactants, and a small amount of about 0, 7 At 1.5% by weight of sodium hydroxide, which reacts in situ with ethoxylated fatty acid 30 to form a clear, non-flowable gelled vehicle, practically free of water and capable of suspending an inorganic particulate abrasive water soluble.

More specifically, the gelled organic composition of the present invention comprises about 65 A

"8 8051 by weight of a substantially anhydrous organic vehicle consisting essentially of about 15 to 3551 by weight of a water-soluble organic solvent and about 35 to 70% by weight of a nonionic surfactant mixture containing an ethoxylated fatty acid such as one of the surfactants, about 0.7 to 1.5% by weight of sodium hydroxide, gelled by in situ reaction of the ethoxylated fatty acid with sodium hydroxide; and about 10 to 25% by weight of an abrasive Csel adjuvant) particulate 10 water-soluble inorganic in uniform suspension in the gelled vehicle.

The water-miscible organic solvent is chosen from glycol ethers alkylated by lower alkyl groups, monoalcohols alkylated by lower alkyl groups, diols alkylated by lower alkyl groups, and mixtures thereof.

The detergents for hard surfaces of the present invention described are thick (viscous), clear, non-pourable and stable pastes, having a minimum viscosity of approximately 14,000-15,000 cps (14 - 15 Pa.s) measured with a viscometer Brookfield HATD. The viscosity of the gelled product gives a stable suspension of relatively large particles of water-soluble abrasives, that is to say larger than the particles of colloidal dimension. The product of the present invention has many applications as a multipurpose detergent. Undiluted with water, the product can be used as a cleaner for sinks and baths, and as a stain remover for hard soiled surfaces, producing a triple cleaning action due to the combined action of organic solvent, non-detergent ionic and abrasive, without leaving the usual ash residue with abrasive detergents. The new organic pastes of the present invention diluted with water can be used as a floor and wall care product. The new organic detergent pastes of the present invention can also be used as anhydrous hand detergents, in particular for mechanics and gardeners; for cleaning cooking vessels, pots etc. industrialists and communities.

The major essential component of the present non-pourable viscous detergent composition is the nonionic surfactant system which constitutes about 35 to 70V. by weight of a mixture of nonionic surfactants containing approximately 6 to 3BV. of an ethoxylated fatty acid, and about 10 A 64V. other nonionic ethoxylate surfactants which may be a fatty alcohol, an alkylphenol, a propylene oxide-propylene glycol condensation product, or a mixture thereof. More specifically, the additional nonionic ethoxylated surfactant can be chosen from a polyethylene oxide condensate of an alkylphenol having an alkyl group having 6 to 12 carbon atoms, a polyethylene oxide condensate of an alcohol aliphatic containing about 8 to 22 carbon atoms, a polyethylene oxide condensate of the condensation product of propylene oxide with propylene glycol with a molecular weight of about 1500 to 1800, and mixtures thereof. Typical examples of polyethylene oxide condensates of alkylphenol are nonylphenol condensed with about 9.5 moles of ethylene oxide per mole of nonylphenol, dodecylphenol condensed with about 12 moles of ethylene oxide per mole of phenol. Typical examples of ethoxylated alcohols include: about 6 moles of ethylene oxide condensed with one mole of tridecanol, myristyl alcohol condensed with about 10 moles of lotiethylene oxide, a C10-Ci- * fatty alcohol condensed with about 6 moles of ethylene oxide, a Cio-C14 alcohol condensed with 5 moles of ethylene oxide per mole of alcohol (CAlfonic 1012-60). Examples of polyethylene oxide condensates with the condensation product of propylene oxide with propylene glycol are commercially available as Pluronic surfactants marketed by the Wyandotte Chemicals Corporation. The liquid character of this product is maintained up to the point where the polyoxyethylene content is approximately 50% of the total weight of the condensation product. Examples of ethoxylated fatty acids include lauric, palmitic, stearic acids, etc., ethoxylated with about 5 to 10 ethylene oxides per mole of fatty acid. A preferred fatty acid ethoxylate is lauric acid having 9 ethylene oxides (CAlkasurf-L-9). The presence of ethoxylated fatty acid in the organic vehicle is essential for gel formation, for the in situ reaction in the organic solvent with sodium hydroxide to form a small amount of soap which thickens and gels organic liquid media. A small amount of sodium hydroxide causes a delayed hydrolysis followed by the geüfinaticn of the vehicle from the ethoxylated fatty acid.

Another essential component of the present cleaning composition is the water-miscible organic solvent in an amount of about 15 to 35% by weight of the total formulation. The organic solvent provides an organic medium for the in situ reaction between the ethoxylated fatty acid and sodium hydroxide for the gelation of the organic medium. Suitable water-miscible organic solvents include monoalcohols alkylated by lower alkyl groups, diols alkylated by lower alkyl groups (glycols), glycol ethers alkylated by lower alkyl groups, and mixtures thereof.

11

Examples of water-soluble lower monoalcohols are ethanol, isopropanol and butanol. Examples of suitable glycols are ethylene glycol, diethylene glycol (Carbitol), and propylene glycol. Examples of lower alkyl glycol ethers are the diethylene glycol monobutyl ether of formula: C ^ HgOCHzCHzOCHzCHzOH also known as Butyl Carbitol (Union Carbide), the ethylene glycol monobutyl ether of formula: C-tHgOCHzCHzQH etc . It is preferred to use a mixture of monoalcohols and diols, and even better a mixture of a monoalcohol, a diol and a glycol ether as the solvent for the nonionic surfactant mixture.

Another essential ingredient in the present viscous cleaning composition is a water soluble inorganic particulate abrasive suspended in the gelled vehicle, in an amount of from about 10 to 257 by weight of the total composition. The abrasive is insoluble in gel but soluble in water. The water-soluble abrasive particles are relatively large particles of about 1/2 mm in diameter. The viscosity of the gelled vehicle which is from one nd-branched 14,000 to 15,000 cs (14 to 15 Pa.s), is capable of irainteiir 'large particles in suspension. Suitable water soluble abrasives are selected from alkali metal phosphates, polyphosphates and carbonates. Examples of suitable water-soluble abrasives include pyrophosphates such as tetrasodium and tetrapotassium pyrophosphates, tripolyphosphates, tetrapolyphosphates, carbonates, etc. This abrasive becomes a surfactant adjuvant when the product is used diluted and is easily removed from the cleaned surface leaving no ash residue. Preferred abrasives include tetrasodium pyrophosphate and sodium carbonate.

12

The hard surface cleaning composition of the present invention may also contain minor amounts of conventional additional components to introduce any desirable characteristic, components which are compatible with the gel and do not adversely affect the structure of the gel. Suitable additives are dyes, perfumes, preservatives, antiseptics etc. These additives represent a maximum of 15% by weight of the composition.

The cleaning compositions of the present invention are generally prepared by mixing water-miscible organic solvent components with an ethoxylated fatty acid and at least one nonionic surfactant component to form a transparent, low viscosity liquid carrier; adding a solution of sodium hydroxide to the clear liquid vehicle and mixing until the liquid gels, which can last from a few minutes to several hours, depending on the quantities of components; and finally by adding to the gelled vehicle the hyposorbent h ^ drcsoldble, an adorant, ui parffun and all aifcæ usual additional ingredient, until the abrasive is uniformly dispersed within the gelled vehicle and that a paste be formed. The detergent composition is packaged in any suitable container, whether rigid or flexible. The dough can be extruded from a compressible container.

The final gelled cleaning product is a stable hard surface detergent with a thick creamy (viscous) appearance, practically anhydrous and having an alkaline pH in the range of about S to 11. It can be applied to the surface 3 clean in any suitable manner, ie with a sponge or cloth, then rinse the surface with water, without leaving 13 ash residue.
