Description
Oppfinnelsen vedrører stabil, i det vesentlige ikke-vandig, konsentrert tøymyknerblanding tilpasset for bruk i skyllesyklusen av en tøyvaskeprosess, og som er lett disper-gerbar i vann når den brukes, særlig i vaskemaskiner med automatiske tilførselsmekanismer. The invention relates to stable, substantially non-aqueous, concentrated fabric softener mixture adapted for use in the rinse cycle of a laundry process, and which is easily dispersible in water when used, particularly in washing machines with automatic feed mechanisms.
Blandinger som inneholder kvaternære ammoniumsalter med minst én langkjedet hydrocarbylgruppe er vanligvis-brukt for å gi tøymyknende fordeler når de anvendes i en tøyskyIling, se f.eks. US patentskrifter nr. 3 349 033, 3 644 203, 3 946 115, 3 997 453, 4 073 735 og 4 119 545. Mixtures containing quaternary ammonium salts with at least one long-chain hydrocarbyl group are commonly used to provide fabric softening benefits when used in a fabric rinse, see e.g. US Patent Nos. 3,349,033, 3,644,203, 3,946,115, 3,997,453, 4,073,735 and 4,119,545.
I de fleste vandige mykningsblandinger som inneholder kationiske kvaternære ammoniumforbindelser som aktive bestanddeler, har konsentrasjonen av slike kationiske forbindelser vanligvis vært begrenset til området fra ca. 3 til 6 vekt% In most aqueous softening compositions containing cationic quaternary ammonium compounds as active ingredients, the concentration of such cationic compounds has usually been limited to the range of about 3 to 6% by weight
(se US patentskrift nr. 3 904 533 og US patentskrift (see US patent no. 3,904,533 and US patent
nr. 3 920 565). En slik lav konsentrasjon er generelt nødvendig-gjort på grunn av det forhold at kationiske forbindelser danner geler i vannblandinger ved konsentrasjoner på over ca. 8%, og selv om bruken av elektrolytter for å senke viskositet i slike blandinger er kjent (se særlig US patentskrift nr. 4 199 545), er slike elektrolytter langt fra tilfredsstillende. Sett fra et funksjonelt synspunkt virker ikke elektrolyttene i nødvendig grad, særlig ved konsentrasjoner av kationiske forbindelser i nærheten av ca. 12 - 15%. Selv om virkningen av elektrolyttene kan forminske noe av geldanningsproblemet, er bruken av dem likevel langt fra tilfredsstillende når det gjelder å frem-skaffe en høykonsentrert vandig blanding av kationiske forbindelser som ikke danner gel eller i alvorlig grad endrer seg med hensyn til viskositet innenfor det vanlige området av tem-peraturer som man støter på ved bruken av disse, f.eks. ca. -18°C og opp til ca. 60°C, eller ved tilførselen i vaskemaskiner. no. 3 920 565). Such a low concentration is generally necessary due to the fact that cationic compounds form gels in water mixtures at concentrations above approx. 8%, and although the use of electrolytes to lower viscosity in such mixtures is known (see in particular US patent document no. 4,199,545), such electrolytes are far from satisfactory. Seen from a functional point of view, the electrolytes do not work to the required extent, especially at concentrations of cationic compounds in the vicinity of approx. 12 - 15%. Although the action of the electrolytes may reduce some of the gelation problem, their use is still far from satisfactory in providing a highly concentrated aqueous mixture of cationic compounds which does not gel or seriously changes in viscosity within the normal the range of temperatures encountered when using these, e.g. about. -18°C and up to approx. 60°C, or when feeding in washing machines.
Ved den vanlige bruk i automatiske vaskemaskiner i europeisk husholdning, plasserer brukeren tøymykneren for skyllesyklusen i en tilførselsenhet (f.eks. en tilførselsskuff) i maskinen. Ved bruken av maskinen, under skyllesyklusen, ut-settes så mykningsmiddelblandingen for en. strøm av kaldt vann for å overføre den til trommelen. Om vinteren, når mykner-blandingen og vannet som tilsettes tilførselsenheten kan være særlig kaldt, kan det være problemer ved at noe av blandingen ikke skylles fullstendig ut av tilførselsenheten under bruken av maskinen, og det kan bygges, opp en avleiring av blandingen etter gjentatte vaskesykluser slik at det kan bli nødvendig for brukeren å skylle tilførselsenheten med varmt vann. Dette problemet kan være spesielt alvorlig for høykonsentrerte myknerblandinger på grunn av det tidligere nevnte geldannings-problem, og også når et ikke-ionisk overflateaktivt . middel er tilstede sammen med den kationiske mykner ettersom det er en tilbøyelighet til at viskositeten av den ikke-ioniske forbindelse øker når den blandes med kaldt vann, slik at det dannes en gel. In common use in European household automatic washing machines, the user places the fabric softener for the rinse cycle in a supply unit (e.g. a supply drawer) in the machine. When using the machine, during the rinse cycle, the softener mixture is then exposed to a stream of cold water to transfer it to the drum. In winter, when the softener mixture and the water added to the dispenser can be particularly cold, there can be problems with some of the mixture not being completely flushed out of the dispenser during machine operation, and a deposit of the mixture can build up after repeated wash cycles so that it may be necessary for the user to rinse the supply unit with hot water. This problem can be particularly severe for highly concentrated plasticizer mixtures due to the previously mentioned gelation problem, and also when a nonionic surfactant. agent is present with the cationic plasticizer as there is a tendency for the viscosity of the non-ionic compound to increase when mixed with cold water to form a gel.
I britisk patentsøknad nr. 2 053 249A publisert 4. februar 1981, er det beskrevet kationiske tøymykningsblandinger som inneholder 15 til 60 vekt% kationisk mykner, 2 5 til 75 vekt% av et vandig medium og 0,5 til 40 vekt% av en nærmere angitt vannoppløselig polymer. British Patent Application No. 2,053,249A published on February 4, 1981, describes cationic fabric softening compositions containing 15 to 60% by weight of cationic softener, 25 to 75% by weight of an aqueous medium and 0.5 to 40% by weight of a indicated water-soluble polymer.
I US patentskrift nr. 4 351 737 er det beskrevet konsentrerte tøymyknere som inneholder både kationiske og ikke-ioniske myknere og et ikke-ionisk dispergeringsmiddel sammen med en oppløsningsmiddelblanding av en C-^-C-j-alkanol og en flytende glycol, polyglycol eller en alkylether derav. Hexylenglycol er ikke beskrevet. US Patent No. 4,351,737 describes concentrated fabric softeners containing both cationic and non-ionic softeners and a non-ionic dispersant together with a solvent mixture of a C-^-C-j-alkanol and a liquid glycol, polyglycol or an alkyl ether hence. Hexylene glycol is not described.
Det er nå funnet at dispergerbarheten i kaldt vann og utstrømningen fra automatiske tilførselsenheter, selv for høykonsentrert flytende blandinger av tøymykningsmidler som inneholder ikke-ionisk overflateaktivt middel, kan forbedres betydelig ved å erstatte en del av .eller hele den flytende bærer i den flytende, ikke-vandige myknerblanding med hexylenglycol. It has now been found that the dispersibility in cold water and the outflow from automatic dispensers, even of highly concentrated liquid mixtures of fabric softeners containing nonionic surfactants, can be significantly improved by substituting some or all of the liquid carrier for the liquid, non -aqueous plasticizer mixture with hexylene glycol.

Den eventuelle ikke-ioniske bestanddel i foreliggende blanding utgjør som nevnt fra 0 til 15 vekt%, fortrinnsvis fra 1 til 12 vekt%, av blandingen og kan generelt variere med den kationisk myknerforbindelse i et vektforhold mellom kationisk forbindelse og ikke-ionisk forbindelse som er fra 25:1 til 3:1, fortrinnsvis fra 12:1 til 6:1, og særlig foretrukket 10:1. Egnede ikke-ioniske forbindelser omfatter kondensater av ethylenoxyd og propylenoxyd (og blandinger derav) med C8-C20 alifatiske alkoholer og mono-, di- og tri-alkylfenoler (idet alkylrestene uavhengig av hverandre er C4-C12). Generelt er de ikke-ioniske forbindelser som her er foretrukket, ikke særlig hydrofile av natur og har en moderat hydrofil gruppe. Ved foreliggende oppfinnelse er denne gruppen fortrinnsvis en oxyethylkjede som vanligvis har minst 2 ende-oxyethylgrupper, selv om der kan være så mye som 200 mol oxyethylen pr. mol av den hydrofobe gruppe. The possible non-ionic component in the present mixture constitutes, as mentioned, from 0 to 15% by weight, preferably from 1 to 12% by weight, of the mixture and can generally vary with the cationic plasticizer compound in a weight ratio between cationic compound and non-ionic compound which is from 25:1 to 3:1, preferably from 12:1 to 6:1, and particularly preferably 10:1. Suitable non-ionic compounds include condensates of ethylene oxide and propylene oxide (and mixtures thereof) with C8-C20 aliphatic alcohols and mono-, di- and tri-alkylphenols (wherein the alkyl residues are independently C4-C12). In general, the nonionic compounds preferred herein are not particularly hydrophilic in nature and have a moderately hydrophilic group. In the present invention, this group is preferably an oxyethyl chain which usually has at least 2 terminal oxyethyl groups, although there may be as much as 200 mol of oxyethylene per moles of the hydrophobic group.
Særlig egnede ikke-ioniske overflateaktive midler omfatter en Cg-C-^ alifatisk alkohol som inneholder 8 mol kon-densert ethylenoxyd, en ethoxylert nonylfenol med 6 mol ethylenoxyd, en ethoxylert octylfenol med 4,5 mol ethylenoxyd og en Cg alifatisk alkohol med 7,5 mol ethylenoxyd. Particularly suitable nonionic surfactants include a Cg-C-3 aliphatic alcohol containing 8 moles of condensed ethylene oxide, an ethoxylated nonylphenol with 6 moles of ethylene oxide, an ethoxylated octylphenol with 4.5 moles of ethylene oxide and a Cg aliphatic alcohol with 7, 5 moles of ethylene oxide.
I tillegg til de ovenfor nevnte forbindelser i mykner-blandingene ifølge oppfinnelsen, kan det også være tatt med en rekke konvensjonelle, supplerende og eventuelle bestanddeler som ikke påvirker stabiliteten og/eller de funksjonelle egenskapene til de foreliggende blandinger på ugunstig måte. Således kan f.eks. de allestedsnærværende parfymer, fargestoffer, pigmenter, opakgjørere, germicider, optiske hvite-midler, antikorrosjonsmidler (f.eks. natriumsilikat), poly-merer, antistatiske midler og lignende være tilstede når de brukes, kan hver utgjøre f.eks. fra 0,01 til 5 vekt% av blandingen. In addition to the above-mentioned compounds in the plasticizer mixtures according to the invention, there may also be a number of conventional, supplementary and possible components which do not adversely affect the stability and/or the functional properties of the present mixtures. Thus, e.g. the ubiquitous perfumes, dyes, pigments, opacifiers, germicides, optical brighteners, anti-corrosion agents (e.g. sodium silicate), polymers, antistatic agents and the like are present when used, each may constitute e.g. from 0.01 to 5% by weight of the mixture.
Det vil selvfølgelig forståes at de fleste tilgjengelige kjemiske stoffer og særlig de som inneholder en hydrocarbyl-rest, generelt er blandinger av nært beslektede rester. Således behøver de langkjedede alkylsubstituenter (R) i de kationiske forbindelser som brukes ved oppfinnelsen, ikke bare være en carbonkjede med en bestemt lengde, men er snarere en blanding. I denne henseende kan et særlig nyttig kvaternært salt hvor alkylgruppene er avledet fra talg, inneholde ca. 35% C^g og 60% C-^g og mindre mengder og til og med også andre. På samme måte kan de alifatiske alkoholfor-løperne for de ikke-ioniske forbindelser som her er brukt, It will of course be understood that most available chemical substances and especially those containing a hydrocarbyl residue are generally mixtures of closely related residues. Thus, the long-chain alkyl substituents (R) in the cationic compounds used in the invention need not only be a carbon chain of a specific length, but are rather a mixture. In this respect, a particularly useful quaternary salt where the alkyl groups are derived from tallow can contain approx. 35% C^g and 60% C-^g and smaller amounts and even others as well. Similarly, the aliphatic alcohol precursors for the nonionic compounds used here can
ha en enkelt carbonkjedelengde, men igjen er det mer sannsynlig at de vil og kan være en blanding i et hvilket som helst mengdeforhold av forbindelsene med virksomme kjedelengder.: De tøymyknende blandinger ifølge oppfinnelsen bør ha viskositeter i området 10 til 250 centipoise, og fortrinnsvis 25 til 150 centipoise, i tillegg til sin essensielle vann-dispergerbarhet i skyllesyklusen (eller en eventuell annen fortynningsform før bruk). have a single carbon chain length, but again it is more likely that they will and can be a mixture in any quantitative ratio of the compounds with effective chain lengths.: The fabric softening compositions according to the invention should have viscosities in the range of 10 to 250 centipoise, and preferably 25 to 150 centipoise, in addition to its essential water dispersibility in the rinse cycle (or any other form of dilution before use).
Måten som hexylenglycolen, de øvrige eventuelle bærere, den kationiske myknerforbindelse og den eventuelle ioniske overflateaktive forbindelse, elektrolytten og de øvrige eventuelle konvensjonelle tilsetningsstoffer blandes på, er ikke spesielt kritisk, og det er heller ikke tilsetningsrekkefølgen. En viss grad av forsiktighet bør imidlertid utøves for å unngå overdreven oppvarmning for å begrense oppløsningsmiddelfor-dampningen og, hvilket er viktigere, holde seg under flamme-punkttemperaturen til bæreren og eventuelle andre lavtkokende væsker som kan være tilstede eller ført inn som bestanddeler The manner in which the hexylene glycol, the other optional carriers, the cationic plasticizer compound and the optional ionic surfactant compound, the electrolyte and the other optional conventional additives are mixed is not particularly critical, nor is the order of addition. However, some care should be taken to avoid excessive heating to limit solvent evaporation and, more importantly, to stay below the flash point temperature of the carrier and any other low boiling liquids that may be present or introduced as constituents
i mykneren og lignende. F.eks. er flammepunktet for hexylenglycol 93°C. Generelt er det imidlertid foretrukket å blande alle bestanddelene ved værelsetemperatur, f.eks. fra ca. 15 til 25°C eller lavere. in the softener and the like. E.g. the flash point of hexylene glycol is 93°C. In general, however, it is preferred to mix all the components at room temperature, e.g. from approx. 15 to 25°C or lower.
En egnet fremgangsmåte for fremstilling av blandingene ifølge oppfinnelsen omfatter oppløsning av ikke-ioniske og andre tilsetningsstoffer (f.eks. hvitemiddel, farge, parfyme, etc.) i bæreren og deretter tilsette denne blandingen til den kationiske forbindelse som fortrinnsvis foreligger i flytende form, f.eks. som en dispersjon i bæreren eller;' A suitable method for producing the mixtures according to the invention comprises dissolving non-ionic and other additives (e.g. bleach, colour, perfume, etc.) in the carrier and then adding this mixture to the cationic compound which is preferably in liquid form, e.g. as a dispersion in the carrier or;'
i en bestanddel av denne (f.eks. som en dispersjon i isopropanol). in a component thereof (e.g. as a dispersion in isopropanol).
Eksemplene nedenunder skal tjene til å illustrere foreliggende oppfinnelse. Med mindre annet er angitt, er alle mengdeandeler basert på vekt. The examples below shall serve to illustrate the present invention. Unless otherwise stated, all quantities are based on weight.
Eksempel 1 Example 1
Ved å følge fremgangsmåten beskrevet ovenfor ble 2 By following the procedure described above, 2
deler av en ethoxylert nonylfenol (som inneholder 6 mol ethylenoxyd) oppløst i ca. 75 deler hexylenglycol ved en tem-peratur på ca. 20°C. Til denne oppløsning ble det sakte tilsatt 20 deler l-methyl-l-((talgylamido)ethyl)-2-talgyl-4,5-dihydroimidazolinium-methylsulfat (75 % aktiv i isopropanol) under omrøring. Man fikk et stabilt produkt med en viskositet på ca. 100 eps. parts of an ethoxylated nonylphenol (containing 6 moles of ethylene oxide) dissolved in approx. 75 parts hexylene glycol at a temperature of approx. 20°C. To this solution was slowly added 20 parts of 1-methyl-1-((talgylamido)ethyl)-2-talgyl-4,5-dihydroimidazolinium methylsulfate (75% active in isopropanol) with stirring. A stable product was obtained with a viscosity of approx. 100 eps.
Eksempel 2 Example 2
Fremgangsmåten ifølge eksempel 1 ble gjentatt under anvendelse av følgende deler (A) kationisk forbindelse (aktiv), The procedure of Example 1 was repeated using the following parts (A) cationic compound (active),
(B) overflateaktiv forbindelse, (NaCl) og (C) hexylenglycol (B) surfactant compound, (NaCl) and (C) hexylene glycol
hexylenglycol/ethylenglycol i vektforholdet 3:1. hexylene glycol/ethylene glycol in the weight ratio 3:1.
Eksempel 3 Example 3
For å vise den forbedrede tilførselsevne for den hexylen-glycolbaserte:; flytende bærer for de konsentrerte mykningsblandinger, ble følgende blandinger A-E fremstilt: To demonstrate the improved delivery capability of the hexylene glycol based:; liquid carrier for the concentrated softening mixtures, the following mixtures A-E were prepared:
Følgende oppløsningsmidler ble brukt: The following solvents were used:
A - 10% isopropylalkohol og 21,9% diethylenglycol (sammenlign.) B - 10% hexylenglycol og 21,9% propylenglycol A - 10% isopropyl alcohol and 21.9% diethylene glycol (comp.) B - 10% hexylene glycol and 21.9% propylene glycol
C - 10% isopropylalkohol og 21,9% hexylenglycol C - 10% isopropyl alcohol and 21.9% hexylene glycol
D - 31,9% hexylenglycol D - 31.9% hexylene glycol
E - 31,9% propylenglycol (sammenligning) E - 31.9% propylene glycol (comparison)
Hver av de ovenfor nevnte myknerblandinger ble tilsatt tilførselsenheten i en typisk europeisk vaskemaskin, AEG-802, og etter 3 kumulative kok-vaskinger (tilførselsenheten ble fylt på nytt for hver vask), ble mengden av blandingen som var tilbake i tilførselsenheten målt. Resultatene er vist i Each of the above-mentioned softener mixtures was added to the feed unit of a typical European washing machine, AEG-802, and after 3 cumulative boil washes (the feed unit was refilled for each wash), the amount of mixture remaining in the feed unit was measured. The results are shown in
tabellen nedenunder som en prosent av den totale mengde som ble brukt (dvs. en trippel-dose): the table below as a percentage of the total amount used (ie a triple dose):
Av resultatene ovenfor kan det lett forståes at bruken av hexylenglycol i stedet for hele eller en del av de konvensjonelle ikke-vandige væskebærerne i tøymyknerblandinger for tilsetning til skyllingen, i stor grad forbedrer dispergerbarheten i kaldt vann og strømningen (tilførselsevnen), selv av konsentrerte blandinger som inneholder ikke-ioniske overflateaktive forbindelser. From the above results, it can be readily understood that the use of hexylene glycol in place of all or part of the conventional non-aqueous liquid carriers in fabric softener blends for addition to the rinse greatly improves cold water dispersibility and flowability (feedability), even of concentrated blends which contain non-ionic surfactant compounds.
Videre er de konsentrerte flytende tøymyknerblandinger ifølge oppfinnelsen stabile i lengre tidsperioder både ved lave, f.eks. 4°C, og høye, f.eks. 3 5°C, lagringstemperaturer, inkludert perioder med nedfrysing og opptining i løpet av 6 uker og mer. Furthermore, the concentrated liquid fabric softener mixtures according to the invention are stable for longer periods of time both at low, e.g. 4°C, and high, e.g. 3 5°C, storage temperatures, including periods of freezing and thawing during 6 weeks and more.
Blandingene ifølge oppfinnelsen har den ytterligere for-del at hexylenglycol er ikke-giftig, og blandingene er derfor sikre å bruke. The mixtures according to the invention have the further advantage that hexylene glycol is non-toxic, and the mixtures are therefore safe to use.
Selv om foreliggende blandinger primært er ment for direkte anvendelse i skylleperioden til automatiske vaskemaskiner, kan de også brukes i fortynnet form og ved manuell behandling, både i og utenfor vaskemaskinen. Although the present mixtures are primarily intended for direct use in the rinsing period of automatic washing machines, they can also be used in diluted form and during manual treatment, both inside and outside the washing machine.
Det skal også forståes at uttrykket "ikke-vandig" slik det her er brukt, betyr at det ikke er meningen å tilsette noe vann til blandingen, selv om mindre mengde vann, f.eks. opp til 5%, kan være tilstede som følge av tilsetning av bestemte bestanddeler, f.eks. fargestoffer, som vandige opp-løsninger, vannet som finnes i mykningsmidlet, etc. It is also to be understood that the term "non-aqueous" as used herein means that no water is intended to be added to the mixture, even if minor amounts of water, e.g. up to 5%, may be present as a result of the addition of certain components, e.g. dyes, such as aqueous solutions, the water contained in the softener, etc.
