Description

LIQUID BUILT DETERGENT COMPOSITIONS This invention relates to liquid built detergent compositions and to their production and use.
In recent times, mainly for reasons of manufacturing economics, aqueous heavy duty built liquid detergents have made in-roads into the spray dried washing powder market with the result that much work has taken place both in relation to the physics and also to the chemistry of product formulation. Such built liquid detergents are often sold in 2 litre plastics bottles. Typical of such products are those described in GB-B-2123846, GB-B-2153839, EP-B0086614 and EP-B-0151884.
As a consequence of this commercial development the spray dried market sector has responded by the introduction of detergent concentrates which are very low in inert ingredients. This means that, without fillers and extenders, the product can be presented to the public with a so-called environmentally-friendly connotation and so that it can be claimed that in use the product is less polluting. This is because very much less product is used per washing machine load because of its strength. In addition the associated packaging can be significantly reduced in comparison to the traditional powder pack with a resulting saving in paper and board.
The use of diethanolamine dodecyl benzene sulphonate in an aqueous heavy duty detergent is mentioned in connection with Table 3 of AU-B-507431.
Another advance in detergent technology occurred when the heavy duty built liquid section of the market responded to the concentrated powder products. As a result there became available liquid detergent concentrates which are typically sold in 1 litre plastics bottles. In view of the greater detergent power of such concentrates the amount of concentrate needed for a typical washing machine load is often about one half of the volume of an aqueoue heavy duty built detergent needed for laundering the same load of washing. Hence a 1 litre battle of concentrate can be ueed Lu wash approximately a· many loads of washing ao a 2 litre bottle of a conventional aqueous heavy duty built liquid detergent. However, to date, this sector has basically been forced to formulate its products either as dispersions of inorganic builders in non-aqueous mixtures of non-ionic surfactants, as in BP-B-0030096 or EP-B-0120659, or as formulations of a non-ionic surfactant mixture in the onuleion otata with a saturated solution of one nr more builders using vegetable gums, or other emulsifying agents, ae stabilisers, ns in GB-A-2148926.
A problem arises with conventional non-aqueous built liquid detergent compositions which contain non-ionio surfaotants as the sole class of surfactant in that they tend to gel upon dispersion in water.
Xn the case of GB-A-2148926 the surfactants in the emulsion are non-ionic surfactants whereas, in the case of SF-B-0120659, claim 9 cites the presence of an anionic surfactant in the composition but the specification completely omits to teach its use in any of its Examples. This omission is because it is difficult in commerce no acquire anionia surfactants, such as sodium dodecyl benzene sulphonate, in the non-pasty solid state (any that do exist are normally offered in admixture with sodium sulphate to prevent the material from being sticky and balling together The prior art therefore does not make use of anionic aurfactanto in non-aqueous built detergent liquide and this is unfortunate because this class of detergent is one of the cheapest and most effective of all the commercially available surface active agents.
In the non-aqueous class cf liquid built detergent - 3 the water analogue of the built system of, for example, GB-B-2153839, is the class of anhydrous solvents known as the polyethylene glycols (P.E.Gs). Liquid members of this class are those with a molecular weight between about 100 and about 600, commonly called PBG.100, PBG.200, PEG.300 and so forth.
It would be desirable to produae a non-aqueous heavy duty built liquid detergent composition with an anionia surfactant as an integral part of the liquid phase in which the builders are dispersed by either rod, bead or ball milling. It would further be desirable to produae a non-aqueous heavy duty built liquid detergent composition whiah does not gel upon dispersion in water* The present invention accordingly seeks to provide a substantially anhydrous liquid built detergent composition containing an anionia surfaatant. It further seeks to provide a substantially anhydrous liquid built detergent composition which shows little or no tendency to gel upon dispersion in water.
According to the present invention there is provided a liquid built detergent composition comprising a substantially anhydrous organic liquid phase having uniformly distributed therein (i) an amine salt of an anionic surfactant acid which contains one or more sulphonic acid groups and (ii) a finely divided partioulate builder.
The organic liquid phase ie substantially anhydrous. In other words it is preferably devoid of added water and contains only that amount of water which is normally present in the ingredients used in production of the liquid built detergent composition of the invention. Henae a composition in accordance with the invention typically contains less than about 5% w/w water, more preferably less than about 2% w/w water, and even more preferably less than about 1% w/w water, e.g. about 0.5% w/w or less, down to about 0.1% w/w or less of water, based upon the total weight of the composition.
The organic liquid phase may include a watersoluble organic solvent. In this case there is provided a liquid built detergent composition comprising a watersoluble organic solvent phase having uniformly distributed therein (i) an amine salt of an anionic surfactant acid which contains one or more sulphonic acid groups and (ii) a finely divided particulate builder.
Normally a significant proportion of the amine salt of the anionic surfactant acid, and preferably all of it, is dissolved in the organic liquid phase, presumably in a form akin to the micelles typically found in aqueous detergent solutions, while the builder is insoluble in the organic liquid phase.
The water-soluble organic solvent may comprise a lower molecular weight alcohol, for example an alkanol containing from 1 to 6, or more preferably 2 to 4 carbon atoms, such as ethanol, n-propanol, iso-propanol. n-butanol or the like. Another suitable class of water-soluble organic solvents is liquid water-soluble organic compounds containing two or more hydroxy groups. Examples of such compounds include ethylene glycol,^propylene glycol, 1,4butylene glycol, 1,5-pentamethylene glycol, glycerol, polyalkylene glycols such as polyethylene glycol, polypropylene glycol, and mixed polyoxyalkylene ether glycols, such as polyoxyethylene-polyoxypropylene glycols, as well as mixtures of two or more thereof.
A preferred type of water-soluble organic solvent is the polyethylene glycols, of which those having molecular weights of at least about 150, for example molecular weights - 5 in the range of from about 200 to about 600, are preferred. However, any solvent that is liquid at ambient temperatures and below (e.g. down to about -10°C), that is water miscible, and that will allow dispersion of the amine salt of the anionic surfactant acid and of the builder can be used. Mixtures of water-soluble organic solvents can be used, if desired. For example, a mixture of an alkanol, such as ethanol or iso-propanol. and a polyethylene glycol can be used.
Normally it will be necessary to incorporate at most a minor amount only of an organic water-soluble solvent or of a mixture of organic solvents, for example, up to about 20% w/w of solvent based upon the total weight of the composition. A preferred range is from about 1% w/w up to about 15% w/w of solvent based upon the total weight of the composition.
One of the purposes for which this solvent, if present, is added may be to adjust the viscosity of the composition to a desired value. A useful degree of control over the viscosity of the composition can be achieved, in particular, by addition of a glycol such as a polyethylene glycol (e.g. polyethylene glycol PEG 200).
Amine salts useful in the practice of the present invention can be prepared by reacting an organic amine with an anionic surfactant acid containing one or more sulphonic acid groups.
Particularly preferred amines are alkanolamines, such as monoethanolamine, diethanolamine and triethanolamine, and heterocyclic monocyclic amines, such as morpholine.
In use the liquid built detergent compositions of the invention will be diluted with water. This dilution step may take place in the wash cycle of an automatic washing machine, for example. Since the builder is normally - 6 alkaline in nature and may typically contain an alkali metal ion, exchange of cations may occur upon dilution of the liquid built detergent composition with water. Thus the quaternary ammonium ion of the salt of the anionic surfactant acid present in the composition may, for example, undergo exchange with sodium ions from the builder. Hence the anions of the anionic surfactant acid may be associated in the resulting aqueous solution with, for example, sodium ions or the ions of another alkali metal, whilst the quaternary ammonium ion, may undergo hydrolysis to yield the free amine. Since some amines have pungent or unpleasant odours, it will normally be preferred to select as the amine salt of the anionic surfactant acid a material which upon hydrolysis of the quaternary ammonium ion does not release an amine with an unpleasant odour. For this reason preferred salts of anionic surfactant acids for use in the compositions of the invention contain alkanolammonium ions or morpholinium ions such as monoalkanolammonium, dialkanolammonium and trialkanolammonium salts of anionic surfactant acids, such as monoethanolammonium, diethanolammonium and triethanolammonium salts of anionic surfactant acids, and morpholinium salts of anionic surfactant acids.
As builder there can be used any of the known builders such as sodium metaphosphate, sodium paraphosphate, sodium tripolyphosphate, sodium silicate, sodium carbonate, a zeolite, a layer silicate, trisodium citrate, or a mixture of two or more thereof. It is beneficial to include an anhydrous material, such as anhydrous sodium carbonate, as an ingredient in the formulation of a non-aqueous liquid built detergent composition according to the invention because the anhydrous material absorbs water to form a solid hydrate of sodium carbonate. In this way any water present or formed in the composition, can be absorbed and the substantially non-aqueous nature of the composition is retained, in addition to the sodium carbonate being available to act as an alkaline builder.
Examples of surfactant acids include alkyl benzene sulphonic acids, in which the alkyl group contains from about 6 to about 20 carbon atoms, for example from 10 to 14 carbon atoms, primary or secondary alkyl sulphonic acids containing from about 10 to about 26 carbon atoms, for example from 10 to 14 carbon atoms, and alpha-olefin sulphonic acids obtained by sulphonation of an alpha-olefin containing, for example from about 10 to about 22 carbon atoms, such as a c16 to C|g olefin or a mixture containing same. Besides a material containing a sulphonic acid group there may also be used for the production of the amine salt or salts, usually in admixture with a material containing a sulphonic acid group, a sulphated fatty alcohol; typical sulphated fatty alcohols include those containing from about 10 to about 26 carbon atoms, for example a sulphated fatty alcohol mixture containing C^q, ^-14^ C16 ant^ ^18 alcohols. Typical of such a fatty alcohol mixture is one containing alcohols in the following proportions: C^q 3.0%, Cj2 57.0%, 20.0%, Cjg 9.0% and Cjg 11.0%.
The composition of the invention may further include one or more non-ionic surfactants. Typical nonionic surfactants include fatty acid monoethanolamides such as coconut fatty acid monoethanolamide, a typical formulation for which is a mixture of monoethanolamides of fatty acids as follows: Cg 0.5%, Cg 6.5%, C^q 6.0%, C^2 49.5%, 19.5%, C^g 8.5%, C^g (stearic) 2.0%, C-^g (oleic) 6.0%, and C^g (linoleic) 1.5%. Other suitable non-ionic surfactants include polyoxyalkylene ethers of alkanols, typically polyoxyethylene ethers of alkanols containing typically 3 or more ethylene oxide groups, for example from about 6 to about 20 ethylene oxide residues and based upon - 8 alkanols containing from about 6 to about 26 carbon atoms. Mixed polyoxyethylene oxypropylene ethers of alkanols can also be used; these can also be based on Cg to C2g alkanols and can contain from about 3 up to about 20 alkylene oxide residues, i.e. a mixture of ethylene oxide and propylene oxide residues. The alkanols and alkanol mixtures upon which such non-ionic surfactants are based can be produced by hydrogenation of methyl esters produced by transesterification of naturally occurring vegetable oils such as coconut oil, sunflower oil, palm oil, rape seed oil, and the like, or of animal fats, such as tallow or lard. A typical polyoxyethylene ether of an alkanol is based upon lauryl alcohol condensed with approximately 8 moles of ethylene oxide. Polyoxyalkylene ethers of alkylphenols are another type of non-ionic surfactant. Mixtures of non-ionic surfactants can be used.
The compositions of the present invention may include an amphoteric surfactant or a mixture of amphoteric surfactants. Typical amphoteric surfactants include dicarboxylated derivatives of oleic imidazoline, caprylo amphocarboxy glycinate, octyl imino dipropionate, octyl dimethyl betaine, complex coco iminodiglycinates, and fatty ampho polycarboxyglycinates. Often a mixture of amphoteric surfactant and non-ionic surfactant are present together in the compositions of the invention. The weight ratio of amphoteric surfactant to non-ionic surfactant may vary within wide limits, for example in the range of from about 1:100 to about 100:1.
Preferably a liquid built detergent composition according to the invention contains at least about 0.1% w/w of an amine salt of an anionic surfactant acid up to about 20% w/w or more, e.g. up to about 25% w/w, even more preferably from about 2% w/w up to about 15% w/w, based on the total weight of said composition. - 9 Preferably a liquid built detergent composition according to the invention comprises from about 0.1% w/w up to about 20% or more of a non-ionic surfactant or surfactants, of an amphoteric surfactant or surfactants, or of a mixture of non-ionic and amphoteric surfactants, even more preferably up to about 35% w/w or more, e.g. up to about 50% w/w, most preferably from about 2% up to about 35% w/w, based on the total weight of the composition.
A liquid built detergent composition according to the invention may further comprise a bleach and, optionally, a bleach activator. Typically such a composition may contain from about 0.1% w/w up to about 10% w/w or more, e.g. up to about 15% w/w of a bleach and, optionally, from about 0.03% w/w up to about 3% w/w or more, e.g. up to about 5% w/w of a bleach activator, based upon the total weight of the composition.
Other minor ingredients which may be included in the composition of the invention include preservatives, optical brighteners, fragrances, foam depressants, foam boosters and/or stabilisers, soaps, dyes, pigments, buffers, corrosion inhibition agents, sequestration agents, antiingestion agents, humectants, enzymes, enzyme stabilisers, fabric softeners, fabric conditioners, and the like.
Typical sequestration agents include ethylene diamine tetraacetic acid, nitrilotrioacetic acid, and acrylic-maleic copolymers such as those sold under the trade mark Polycarboxylate AMC. One or more of these minor ingredients can be included in the compositions of the invention as appropriate. Such other minor ingredients typically comprise not more than about 5% w/w each of the compositions of the invention, for example in the range of from about 0.001% w/w up to about 2% w/w each based upon the total weight of the composition.
The compositions of the invention may be formulated - 10 so as to have approximately the same laundering power as conventional aqueous heavy duty built liquid detergents. Preferably, however, the compositions of the invention will be formulated as concentrates which have several times, e.g. about 2 to about 5 times, the laundering power of conventional aqueous heavy duty built liquid detergents. To this end it is desirable to formulate the compositions as concentrates in which the solid components comprise in total at least about 30% w/w and preferably at least about 45% w/w up to about 50% w/w or even higher, based upon the weight of the composition.
The invention further provides a process for the production of a liquid built detergent composition which includes the step of reacting in an organic phase an anionic surfactant acid containing one or more free sulphonic acid groups with an amine. Such an amine may be a primary amine, a secondary amine, or a tertiary amine.
In one form of the process the reaction is carried out in an organic phase which includes a water-soluble organic solvent. In this case there is provided in accordance with the invention a process for the production of a liquid built detergent composition which includes the step of reacting an anionic surfactant acid containing one or more free sulphonic acid groups in an organic solvent phase comprising a water-soluble solvent with an amine. The amine may be a primary amine, a secondary amine, or a tertiary amine.
Hence the invention contemplates producing in-situ quantities of organic base salts of anionic surfactant sulphonic acids. By this means highly successful built liquids can be produced from solutions of an acid such as dodecylbenzene sulphonic acid in PEG 200 (polyethylene glycol 200), in alkylene oxide addition products, or in a blend of both. Such solutions may further contain anhydrous - ii non-ionic surfactants. The organic bases which were used were mono-, di-, and triethanolamine and morpholine but any primary, secondary or tertiary amine without an unpleasant odour can be used. From these materials very transparent pale yellow syrups can be produced which are excellent vehicles for carrying the silicate, carbonate, phosphate and polyphosphate builders which are to be micronised to give the non-aqueous built laundry liquids.
As an example of this technology the following solution was prepared:Dodecyl Benzene Sulphonic Acid 67.5 gms Fatty Alcohol Ethoxylate (4 moles of E.O) 15.0 gms Alkylene Oxide Addition Product (Marlox FK 64) 100.0 gms Polyethylene Glycol 200 75.0 gms (The word Marlox is a trade mark).
The above ingredients were simply stirred together in any order to give an amber syrup. This solution was then converted to the quaternary ammonium salt of the sulphonic acid by titration with one of the previously mentioned amines. The resulting syrups had the following viscosity: Viscosities at 25°C (mPa) Triethanolamine salt 275 Diethanolamine salt 247 Monoethanolamine salt 254 Morpholine salt 261 A further series of similar syrups can be prepared by omitting the polyethylene glycol or the fatty alcohol ethoxylate.
When any of these syrups was mixed with a builder such as sodium tripolyphosphate (35%), sodium silicate Soluble C powder or sodium carbonate (5% each) and micronised by milling, the result was a fully built pourable liquid laundry detergent. All the other usual minor - 12 ingredients could be added and are compatible, including soaps which can be formed in-situ by having a fatty acid in solution in the PEG mixture prior to titration with the amine.
The invention is further illustrated in the following Examples.
EXAMPLE 1 A liquid built detergent concentrate is produced from the following ingredients:IE 914108 - 13 % w/w Dodecyl Benzene Sulphonic Acid 11.5 Alkylene Oxide Addition Product (Marlox FK 64) 12.0 Alcohol Ethoxylate (4 moles E.O.) 3.0 Coconut Fatty Acid 5.2 Triethanolamine 8.5 Polyethylene Glycol (PEG 200) 12.0 Sub-total 52.2 Sodium Silicate (Soluble C powder) 5.0 Sodium Carbonate Anhydrous (Soda Ash) 5.0 Sodium Tripolyphosphate 35.0 Minor Ingredients 2.8 Sub-total 47♦8 Total 100.0 All the organics, with the exception of the triethanolamine, are mixed together to yield a dark amber syrup. To this is added enough triethanolamine for neutralisation; the approximate end point corresponds to the syrup colour becoming a lighter yellow. To this syrup are added all the other ingredients and the mixture is then micronised in a bead mill. In this preparation the presence of the sodium carbonate is bifunctional in that it acts both as an alkaline builder in the product and a drying agent.
