Abstract
Detergent compositions are disclosed which comprise a fabric softening, smectite-type clay. The clay is treated with organic humectants to enhance the softening benefit.
[EP0313146A2]
Description
61 3 4 5 i * t- DETERGFWT COMPOSITIONS The present invention relates to detergent compositions containing a fabric-softening amount of a smectite-type clay. The clay is present in the form of 5 agglomerates which comprise from 0.5% to 30% of an organic humectant.
British Patent 1,572,815 discloses a detergent composition based on soap and a curd-dispersing agent. The compositions comprise from 4% to 25% of a 10 smectite-type clay. The clay is agglomerated with water, an aqueous electrolyte solution, a nonionic surfactant, or an aqeuous solution of an organic adhesiue. Examples I- 2 of such adhesives include dextrin, gelatine, carboxymethyl-cellulose, starch, carboxymethyl starch, and alkwl and hyroxy al kyl substituted celluloses and ,J starches. The agglomerates ©re disclosed to minimize dustiness while the full softening potential of the clay is preserved.
British Patent 1,167,037 discloses clays that have been treated with alkanolamine salts and an organic humectant. The treated clays are disclosed to hydrate 10 rapidly and to develop viscosity in a short period of time as compared to untreated clays.
European Patent Application 164 797 discloses detergent compositions comprising agglomerates of smectite clay which are sprayed with a dispensing aid such as quaternary aasiooiuax 15 compounds.
French Patent Application 2 524 903 discloses detergent compositions comprising agglomerates of clay with binders such as sodium silicate, gums, resins and organic polymers.
European Patent Application 287344, published on 19th October, 2o 1988, is a part of the prior art according to Article 54(3) EPC. It discloses softening clay in intisaate contact with a nonionic surfactant system.
British Patent 1,400,898 discloses detergent compositions comprising, as a fabric softening ingredient, a smectite-type clay.
It is now well recognised in the detergent industry that claws of the type disclosed in British Patent 1,400,898 prouide significant fabric softening benefits when used in a laundry detergent. Yet, it is equally well recognized that deposition of these clays onto th® fabrics during the laundering process is far from complete; in feet, under typical European laundry conditions, less than half of the available clay is deposited onto the fabrics, the remainder being rinsed away with the laundry liquor during the subsequent rinsing steps. Moreouer. the softening effect obtained as a result of the clay deposition is affected by factors that ar© not well understood.
It is, therefore, an object of the present invention to pretreat fabric-softening clays so as to increase the softening benefit obtained.
Summary of the Invention The present invention relates to the granular detergent compositions comprising a) conventional detergent ingredients; and b) clay ©gglotnerates comprising from 60% to 99.5% smectite-type clay and from 30% to 0.5% of an organic humectant. The humectan"ts are selected fronK glycerol, ethylene glycol, propylene glycol, dimers and trimers of glycerol and mixtures thereof. Highly preferred agglomerates further comprise, by weight of the claw, from 0.005% to 20% of © claw flocculating agent.
Pre-f erred claw flocculating agents are polymers like poly(ethylene oxide), poly(acryl amide) and poly(acrylate), having a weight average molefcular weight of from 100.000 to iO million. Host preferred are poly (ethylene oxide) polymers having a molecular weight (weight average) in the range lSO.000 to 5 million.
Detailed Description of the Invention The detergent compositions of the present invention comprise conventional detersive surfactants, conventional detergent builders and, optionally, other conventional detergent ingredients. The compositions further comprise a fabric-softening amount, typically from l% to 3 5% by weight preferably from 3% to 15% by weight of the detergent composition, of the fabric-softening clay agglomerates herein.
Percentages herein are percentages by ujeight of the detergent compositions, unless otherwise specified.
Detergent Ingredients Detersive Surfactants - The compositions of this 5 invention will typically contain organic surface-actiue agents ("surfactants") to provide the usual cleaning benefits associated with the use of such materials. Detersiue surfactants useful herein include well-known synthetic anionic, nonionic, amphoteric and zwitterionic 10 surfactants. Typical of these are the alkyl benzene sulfonates, alkyl- and alkvlether sulfates, paraffin sulfonates, olefin sulfonates, alkoxylated (especially ethoxylated) alcohols and alkyl phenols, amine oxides, alpha-sulfonates of fatty acids and of fatty acid esters, 15 and the like, which are uell-knoujn from the detergency art. In general, such detersiue surfactants contain an alkyl group in the Cg-C,g range; the anionic detersiue surfactants can be used in the form of their sodium, potassium or triethanolammonium salts; the nonionics 20 generally contain from about S to about 17 ethylene oxide groups. U.S. Patent 3 995 669 contains 'detailed listing of such typical detersive surfactants.
C, -C,, alkyl benzene sulfonates, C,_-C_. 11 10 12 18 paraffin-sulfonates and alkyl sulfates, and the 25 ethoxylated alcohols and alkyl phenols ©re especially preferred in the compositions of the present type. Also useful herein as the surfactant are the water- soluble soaps, e.g. the common sodium and potassium coconut or tallow soaps well-known in the art.
The surfactant component can comprise as little as 1% of the compositions herein, but preferably the composi- 6 tions will contain 5% to 40%, preferably 10% to 30%, of surfactant. Mixtures of the ethoxylated nonionics with anionics such as the alkyl benzene sulfonates, alkyl sulfates and paraffin sulfonates are preferred for 5 through-the-wash cleansing of a broad spectrum of soils and stains from fabrics.
Detersiue Adjuncts - The composition herein can contain other ingredients which aid in their cleaning performance. For example, it is highly preferred that 10 through-the-was h detergent compositions contain a detergent builder and/or metal ion sequestrant. Compounds classifiable and well-known in the art as detergent builders include the nitrilotriacetates, polycarboxylates, citrates, carbonates, zeolites, water-soluble phosphates such as 15 tri-polyphosphate and sodium ortho- and pyro-phosphates, silicates, and mixtures thereof. Metal ion sequestrants include all of the above, plus materials like ethylenediainine tetraacetate, the ami no-poly phosphonates (DEQUEST) ©nd a wide variety of other 20 poly-functional organic acids and salts too numerous to mention in detail here. See U.S. Patent 3 579 454 for typical examples of the use of such materials in various cleaning compositions. In general, the builder/sequestrant will comprise about 0.5% to 45% of the 25 composition. The i-10 micron size zeolite (e.g. zeolite A) builders disclosed in German patent 2 422 655 are especially preferred for use in low-phosphate compositions.
Particularly suitable phosphate-free builders are ether carboxylase mixtures comprising ? a) from 1% to 99% of a tartrate monosuccinate component ot the structure HOCH CH 0 — CH CH2 COOX COOK COOK COOK wherein X is H or salt-forming cation; and b) from 1% to 99% by weight of a tartrate disuccinate component of the structure : CH2 CH 0 —CH' CH 0 CH CH2 COOK COOK COOX COOX COOX COOX uiherein X is H or a salt-forming cation.
Builder systems of this type are more fully disclosed 10 in U.S. patent W° 4,663,071.
Typical detergent compositions contain from 5% to 35% of this builder system.
The laundry compositions herein also preferably contain enzymes to enhance their through-the-wash cleaning 15 performance on a variety of soils and stains. Amylase and protease enzymes suitable for use In detergents are mell-known in the art and in commercially available liquid and granular detergents. Commercial detersiue enzymes (preferably a mixture of amylase and protease) ©re 20 typically used at levels of 0.001% to 2%, and higher, in the present compositions. Detergent cellulase enzymes 8 provide both cleaning and softening benefits, particularly to cotton fabrics. These enzymes are highly desirable in the detergent compositions of this invention.
The compositions herein can contain other ingredients 5 which aid in their cleaning performance. For example, the compositions herein can advantageously contain a bleaching agent, especially a peroxyacid bleaching agent. In the context of the present invention, the term peroxyacid bleaching agent encompasses both peroxyacids per se and 10 systems which are able to yield peroxyacids i_n situ.
Peroxyacids per se are meant to include the alkaline and alkaline-earth metal salts thereof. Peroxyacids and diperoxyacids are commonly used; examples are diperoxydodecanoic acid (DPDA) or peroxyphthalic acid.
Systems capable of deliuering peracids in situ consist of a peroxygen bleaching agent and an activator thereof.
The peroxygen bleaching agents are those capable of yielding hydrogen peroxide in an aqueous solution; these 20 compounds are u;ell-known in the art, and include hydrogen peroxide, alkali-metal peroxides, organic peroxide bleaching agents such as urea peroxide, inorganic persalt bleaching agents such as alkali metal perborates, percarbonates, perphosphates, persilicates, and the like.
Preferred are sodium perborate, commercially available in the form of mono- and tetra-hydrates, sodium carbonate peroxyhydrate, sodium pyrophosphate peroxyhydrate and urea peroxyhydrate.
The liberated hydrogen peroxide reacts with a bleach 30 activator to form the peroxyacid bleach. Classes of 9 bleach activators include esters, Amides, imidazoles, oximes, and carbonates. In these classes, preferred materials include methyl o-acetoxy benzoates; sodium-p-acetoxy benzene sulfonates such as sodium 5 4-nonanoxyloxybenzene sulfonate; sodiurn-4-octanoylox y benzene sulfonate, and sodium-4-decanoyloxybenzenesulfonate : biophenol A diacetate; tetra acetyl ethylene diamine; tetra acetyl hexemethylene diamine; tetra acetyl methylene diamine.
Other highly preferred peroxygen bleach activators which are disclosed in U.S. Patents 4,483, 778 and 4,539, 130 are alpha-substituted alkyl or alkenyl esters, such as sodium-4(2-chiorooctanoyloxy)benzene sulfonate, sodium 4-(3,5,5-trimethyl hexanoyloxy)benzene sulfonate.
Suitable peroxyacids are also peroxygen bleach activators such as described in published European Patent Application W° 0 116 571, i.e., compounds of the general type RXAOOH and RXAL, wherein R is a hydroxcarbyl group, X is a hetero-atom, A is a carbonyl bridging group and L is a leaving group, especially oxybenzenesulfonate.
Other highly desirable detergent ingredients for use in the detergent compositions of the present invention are quaternary ammonium compounds of the formula R„RcR-R_MtX~, wherein R, is alfcvl having 4 b 0 / ^ from 8 to 20, preferably from 12-18 carbon atoms, is alkyl having from 1 to 10 carbon atoms, and and R„, are each C, to Cs alkvl preferably methyl : X~ is an J, anion, e.g. chloride. Examples of such quaternary ammonium compounds include C , „-C, ... a 1 kw 1 trlrnethyl I 4 I «■» ammonium chloride and cocoalkyl trimethyl ammonium methosulfate. The quaternary ammonium compounds can be used at levels from 0.5% to 5%, preferably from 1% to 3%. 1! 0 The fabric softening clay Smectite-type clays are uiidely used as fabric softening ingredients in detergent compositions. Most of these claws haue a cation exchange capacity of at least 50 5 meq/iOOg.
Flontmorrillonite clays are commonly used for this purpose. It appears, however, that certain hectorite clays provide better fabric softening performance than the more commonly used montmorillonites. The hectorites 10 exhibiting this superior fabric softening performance are hectorites of natural origin hauing a lath-type shape.
According to the present invention, the fabric < softening clay is present in the form of agglomerates. These agglomerates comprise, in addition to the clay, an 15 organic humectant. The agglomerates optionally further comprise a polymeric clay flocculating agent. Typically, the agglomerates comprise by weight of the agglomerate, from 60% to 99.5% of the clay; from 0.5% to 30% of the humectant; and from 0% to 10% of the clay flocculating 20 agent. Preferably, the agglomerates further contain a heauy metal sequestering agent. Examples include heavy metal chelators, like EDTA and ethylenediarnine tetramethylene phosphonic acid (EDTP). The agglomerates typically contain from 0.1% to 10% of the chelator.
The humectant The humectants are selected from glycerol, ethylene glycol, propylene glycol and the dimers and trimers ox glycerol and mixtures thereof.
The clay agglomerates comprise from 0.S% to 30%, preferably From 2% to 15%, of the humectant.
The optional clay flocculating agent Clay-flocculating agents are not commonly used in detergent compositions. On the contrary, one is inclined TO to use clay dispersants, which aid in removing clay stains from fabrics. Flocculating agents are, houjeuer, very well known in other industries like oil i«je 11 drilling, and for ore flotation in metallurgy. Most of these materials are fairly long chain polymers and copolymers derived from 15 such monomers as ethylene oxide, acrvlamide, acrylic acid, dirnethylamino ethyl met ha cry late , vinyl alcohol, vinyl pyrrolidone, ethylene imine. Gums, like guar gum, are suitable as well.
Preferred are polymers of ethylene oxide, acryl 20 amide, or acrylic acid. It has been found that these polymers dramatically enhance the deposition of a fabric softening clay if their molecular weights (weight average) are in the range of from 100,000 to 10 million. Preferred are such polymers having a (weight average) molecular 25 weight of from 150.000 to 5 million.
The most preferred polymer is poly (ethylene oxide). Molecular weight distributions can be readily determined using gel permeation chromatography, against standards of poly (ethylene oxide) of narrow molecular weight 30 distributions. 1 2 The clay agglomerates herein comprise, by weight of the clay, from 0% to 20% clay flocculating agent, 6 preferably from 0.05% to 20% by weight of the clay if the molecular weight is 150.000 - 800.000 and from 0.005% to V 5 2% by weight of the clay if its molecular weight is from 800.000 to 5 million.
Additional softening ingredients The detergent compositions of the present inuention may further contain, in addition to the clay material, other softening ingredients. Suitable examples include amines of the formula R„R_R_N, wherein R„ is 12 3 lo to C2Q hydrocarbyl, R^ is to C2Q hydrocarbyl, and R3 is Cj to hydrocarbyl or hydrogen. A preferred amine of this type is dital]owmethylamine .
Preferably, the softening amine is present as a complex with a fatty acid of the formula RCOOH, wherein R is a 0^ to C2Q alkyl or alkenyl. It is desirable that the amine/fatty acid complex be present in the form of microfine particles, hauing a particle size in the range 20 of from, e.g. , 0.1 to 20 micrometers. These amine/fatty acid complexes are disclosed more fully in European Patent Application N° 0 133 804. Preferred are compositions that contain from 1% to 10% of the amine.
Suitable are also complexes of the aboue described 25 amine and phosphate esters of the formula R „0 OH and HO OH OR, OR, I 3 wherein Rg and R^ are C^alkyl, or ethoxylated ©1ky1 groups of the general formula alkyl-(OCH CH ) , wherein the alkyl substituent is 2 ^ 0 C (""C?o' preferably C^-C^ ^, and y Is an integer of 5 1 to 15, preferably 2-10, most preferably 2-5.
V Amine/phosphate ester complexes of this type are more fully disclosed in European Patent Application N° 0 168 889 „ Further examples of optional softening ingredients 10 include the softening amides of the formula R^qR, ^COR, 2, wherein R1Q and R?1 are independently selected from C^-C^ alkyl, alkenyl, hydroxy alkyl, aryl, and alkyl-aryl groups; is hydrogen, or a Cj-C^^ alkyl or alkenyl, an aryl or 15 alkyl-aryl group. Preferred examples of these amides are ditallow acetamide and ditallow benxamide. Good results are obtained when the amides are present in the composition in the form of a composite with a fatty acid or with a phosphate ester, as described hereinbefore for 20 the softening amines.
The amides are present in the composition at l%~10% by weight.
Suitable softening ingredients are also the amines disclosed in U.K. Patent Application G8 2 173 827, 25 in particular the substituted cyclic amines disclosed therein. Suitable are imidazolines of the general formula l-(higher alkyl) amido (lower alkyl)-2-(higher alkyl)imidazoline wherein higher alkyl is alkyl haying from 12 to 22 carbon atoms, and lower alkyl is alkyl 30 hawing from 1 to 4 carbon atoms.
L A preferred cyclic amine is l-tallowamidoethyl-2-tallowimida2oline. Preferred S 4 compositions contain from 1% to 10% of the substituted cyclic amine.
The amine and amide softening ingredients may be added as a dry powder to a detergent granule, or may be 5 sprayed onto the detergent granule or onto a carrier, either in melted or in dissolved form. An example of a suitable carrier is perborate monohydrate.
Moreover, the compositions herein can contain, in addition to ingredients already mentioned, various other 10 optional ingredients typically used in commercial products to provide aesthetic or additional product performance benefits. Typical ingredients include pH regulants, perfumes, dyes, bleach, optical brighteners, soil suspending agents, hydrotropes and gel-control agents, 15 freeze-thaw stabilizers, bactericides, preservatives, suds control agents, bleach activators and the like.
In a through-the-wash mode, the compositions are typically used at a concentration of at least 400 ppm, preferably 0.05% to 1.5%, in an aqueous laundry bath at pH 20 7-11 to launder fabrics. The laundering can be carried out over the range from 5°C to the boil, with excellent results.
Industrial Application The agglomeration process Itself may be performed using 25 any of the techniques and apparatus which are conventional in the art (see e.g. "A review of Detergent Agglomeration" - M.J. DOLAW, HAPPI, April 1987 p 64-85). It can be batchwise or continuous. The optimum operating conditions (preferred granule size and moisture level) can be found 30 by trial adjustments of process parameters such as the liquid spray-on leuel, rate and droplet size, the residence time, etc.
I: 5 EXAMPLE 1 40 kg of a commercial smectite clay (CEC BO meq/lOOg.) i were sprayed with 5 1. of a 40% by weight aqueous solution of glycerol in a Lodige drum agglomerator. After drying V' and sieging, the following agglomerate composition was obtained : Smectite clay (anh.) 81.9% Glycerol 4.1% Moisture 14.0% Granulometry : 212 jjjn (65 mesh) < min. 80% < 850 (20 mesh) .
A reference agglomerate, i.e. no glycerol was made in the same way. 1 5 Both agglomerates were dry mixed with a spray-dried granular detergent to yield the following compositions: LAS ST P P EDT A Brightener Sodium silicate Suds suppressor NA.CO, 2 3 PB4 Proteolytic enzyme (*) 7 24 0.2 0.2 6.0 0.4 10.0 20.0 0.5 7 24 0.2 0.2 6.0 0. 4 10.0 20.0 0.5 Wa2S04 H2° balance 93.5 93 . 5 1 6 Clay/ glycerol agglomerates 6.5 Clay Reference agglomerate — 6.5 100.0 100.0 (*) Dry mixed The compositions ft and B were then used to wash 4 Kg clean fabric loads in a MIELE washing machine. The water hardness was 3.0 mmol (Ca*~ -f- Mg "r"r)/l and the detergent concentration was 10 g/1. Clean terry towel tracers were added to permit evaluation of 1 cycle and cumulative (4 cycles) softening performance. Softness tracers were line dried prior to assessment .by expert judges. ft 0 > 4 panel score units (p.s.u.) scale was used for grading, in which 0 means no difference and 4 stands for a very big difference.
Composition A was rated better for softness than B : 1 cycle tracers 0.6 p.s.u. (s) 4 cycle tracers 0.8 p.s.u. (s) (s) Differences are statistically significant at 95% confidence level.
It can thus be seen that composition A, in accordance with the invention is superior in fabric softening performance to the prior art composition A.
The following agglomerate compositions are obtained, using the procedure outlined under Example 1 ii in iu g Smectite clay (anh.) 79.5% 83.4% 81% 74% , Ethylene glycol 8.0% 2.1% - 6 % Sorbitol - 4% - Polyethylene oxide (1) - - - 5 % Moisture 12.5% 14.5% 15% 13 % EDTP - - 2 % (1) hauing weight average molecular weight of about 300.000.
The clay agglomerates may also be incorporated in a laundry additive, as such or with the aid of a water soluble and/or insoluble carrier such as e.g. a sheet or a pouch. These agglomerates, as such or with a suitable carrier, can then be added to the wash liquor on top of a 15 conventional detergent composition. The laundry additive preferably also contains one or more of the additional softening ingredients specified before. The additive may thus be used in conjunction with detergent compositions that themselves do not contain such a clay and/or these 20 other softening ingredients.
