Description
Titel: Vloeibare wasverzachtersamenstellingen.Title: Liquid fabric softener compositions.
De uitvinding heeft betrekking op vloeibare waterige wasverzachtersamenstellingen op basis van biologisch afbreekbare kationogene wasverzachters.The invention relates to liquid aqueous fabric softener compositions based on biodegradable cationic fabric softeners.
Wasverzachters worden al meer dan 25 jaar toegepast voor het nabehandelen van gewassen textielprodukten. Wasverzachtersamenstellingen bestaan uit waterige dispersies van kationogene wasverzachters. Gewoonlijk bevatten deze samenstellingen ook nog een aantal hulpstoffen zoals vetalcoholen, vetzuren, emulgatoren, geurstoffen, kleurstoffen, conserveermiddelen en elektrolyten.Fabric softeners have been used for the after-treatment of washed textile products for more than 25 years. Fabric softener compositions consist of aqueous dispersions of cationic fabric softeners. Usually, these compositions also contain a number of auxiliary substances such as fatty alcohols, fatty acids, emulsifiers, fragrances, dyes, preservatives and electrolytes.
Wasverzachtersamenstellingen worden meestal na het wasproces toegevoegd aan het laatste spoelwater in een wasmachine. De kationogene wasverzachters worden door de anionische textielvezels geadsorbeerd en verlenen aan het gedroogde textielprodukt de gewenste zachte "greep" en antistatische eigenschappen. Daarnaast heeft de toepassing van wasverzachtersamenstellingen nog andere gunstige effecten op het gedroogde textielprodukt, zoals een aangename geur, een verbeterde strijkbaarheid en een hogere slijtvastheid.Fabric softener compositions are usually added to the final rinse water in a washing machine after the washing process. The cationic fabric softeners are adsorbed by the anionic textile fibers and impart the desired soft "grip" and anti-static properties to the dried textile product. In addition, the use of fabric softener compositions has other beneficial effects on the dried textile product, such as a pleasant odor, improved ironability and higher abrasion resistance.
De in de wasverzachtersamenstellingen aanwezige vetzuren en/of vetalcoholen hebben een gunstige invloed op de zachtheid van het gedroogde textielprodukt (functie als co-softeners). Daarnaast spelen deze verbindingen een rol bij het stabiliseren van de viscositeit van de wasverzachtersamenstellingenThe fatty acids and / or fatty alcohols present in the fabric softener compositions favorably affect the softness of the dried textile product (function as co-softeners). In addition, these compounds play a role in stabilizing the viscosity of the fabric softener compositions
Bekende wasverzachters zijn de kwatemaire ammoniumzouten zoals distearyldimethylammoniumchloride (DSDMAC) en bepaalde imidazoliniumzouten zoals alkylmethylimidazoliniumchloride.Known fabric softeners are the quaternary ammonium salts such as distearyl dimethyl ammonium chloride (DSDMAC) and certain imidazolinium salts such as alkyl methyl imidazolinium chloride.
Tot omstreeks 1990 werden nagenoeg uitsluitend wasverzachters gebruikt die slecht biologisch afbreekbaar zijn.Until about 1990 almost exclusively fabric softeners were used that are poorly biodegradable.
In veel landen wil de consument vloeibare wasverzachtersamenstellingen gebruiken die een visceuze textuur bezitten. Een visceuze waterige samenstelling met niet-biologisch afbreekbare wasverzachters kan verkregen worden door aan- passing van het produktproces, door toepassing van geschikte vetzuren of vetalcoholen en/of door toepassing van bepaalde verdikkingsmiddelen. Volgens het Europese octrooischrift 51.983 worden guargom, bepaalde guargomderivaten, polyacryl-amiden en polyvinylacetaat toegepast als verdikkingsmiddel in vloeibare wasverzachtersamenstellingen. in dit octrooischrift wordt vermeld dat kationogene guargomprodukten niet geschikt zijn omdat er flokkulatie van de kationogene wasverzachters optreedt (blz. 2, laatste alinea). De toegepaste verdikkingsmiddelen moeten ervoor zorgen dat de viscositeit van de visceuze wasverzachtersamenstellingen bij langdurig bewaren niet in ongewenste mate verandert.In many countries, consumers want to use liquid fabric softener compositions that have a viscous texture. A viscous aqueous composition with non-biodegradable fabric softeners can be obtained by adjusting the product process, by using suitable fatty acids or fatty alcohols and / or by using certain thickeners. According to European Patent 51,983, guar gum, certain guar gum derivatives, polyacrylamides and polyvinyl acetate are used as a thickener in liquid fabric softener compositions. this patent discloses that cationic guar gum products are unsuitable because the cationic fabric softeners are subject to flocculation (page 2, last paragraph). The thickening agents used must ensure that the viscosity of the viscous fabric softener compositions does not change undesirably during long-term storage.
De toepassing van biologisch niet-afbreekbare wasverzachters en hulpstoffen stuit op steeds meer weerstand vanwege de milieuproblemen die zij veroorzaken. Daarom zijn inmiddels door diverse producenten biologisch afbreekbare wasverzachters op de markt gebracht. Deze biologisch afbreekbare wasverzachters zijn onder andere beschreven in de Europese octrooiaanvragen 293.953 en 293.955 en in het Amerikaanse octrooischrift 4.789.491. Vloeibare wasverzachtersamenstellingen, die biologisch afbreekbare wasverzachters bevatten, zijn echter vaak onvoldoende stabiel gedurende bewaren (zie de Europese octrooiaanvrage 293.953, pag. 2, regels 26-28 en het Amerikaanse octrooischrift 4.789.491, kolom 1, regels 44-48) . Er is dus behoefte aan verdikkingsmiddelen voor deze wasverzachtersamenstellingen die biologisch afbreekbaar zijn en die de viscositeit van deze samenstellingen gedurende langere tijd stabiliseren.The use of biologically non-degradable fabric softeners and auxiliary materials is meeting increasing resistance because of the environmental problems they cause. That is why biodegradable fabric softeners have now been marketed by various manufacturers. These biodegradable fabric softeners are described, inter alia, in European Patent Applications 293,953 and 293,955 and in U.S. Patent 4,789,491. However, liquid fabric softener compositions containing biodegradable fabric softeners are often insufficiently stable during storage (see European Patent Application 293,953, page 2, lines 26-28 and U.S. Patent 4,789,491, column 1, lines 44-48). Thus, there is a need for thickeners for these fabric softener compositions that are biodegradable and that stabilize the viscosity of these compositions over time.
Volgens het Amerikaanse octrooischrift 4.789.491 kan men in wasverzachtersamenstellingen, die biologisch afbreekbare wasverzachters bevatten, als verdikkingsmiddelen cellulose-ethers, bepaalde synthetische polymeren (polyvinylalcohol, polycarboxypolymeren) of kationogene guargomderivaten toepassen (kolom 12, regels 32-38) . Bezwaren tegen deze verdikkingsmiddelen zijn hun hoge prijs en/of hun geringe biologische afbreekbaarheid.According to U.S. Patent No. 4,789,491, fabric softener compositions containing biodegradable fabric softeners may use cellulose ethers, certain synthetic polymers (polyvinyl alcohol, polycarboxy polymers) or cationic guar gum derivatives (column 12, lines 32-38) as thickeners. Objections to these thickeners are their high price and / or their low biodegradability.
Aanvraagster heeft nu gevonden, dat als verdikkingsmiddel in vloeibare wasverzachtersamenstellingen, die biologisch afbreekbare wasverzachters bevatten, met voordeel kationogene zetmeelprodukten toegepast kunnen worden. Deze kationogene zetmelen zijn relatief goedkoop en zijn in hoge mate biologisch afbreekbaar.The applicant has now found that as thickener in liquid fabric softener compositions containing biodegradable fabric softeners it is advantageous to use cationic starch products. These cationic starches are relatively inexpensive and are highly biodegradable.
De uitvinding heeft derhalve betrekking op vloeibare waterige wasverzachtersamenstellingen op basis van biologisch afbreekbare wasverzachters, waarbij als verdikkingsmiddel verstij fseld kationogeen zetmeel in de samenstelling aanwezig is.The invention therefore relates to liquid aqueous fabric softener compositions based on biodegradable fabric softeners, in which thickened cationic starch is present as thickener in the composition.
Gebleken is, dat samenstellingen met kationogeen zetmeel als verdikkingsmiddel een verrassend hoge viscositeit bezitten. Dit betekent dat voor het vervaardigen van samenstellingen met een bepaalde gewenste viscositeit relatief weinig kationogeen zetmeel nodig is.It has been found that compositions with cationic starch as a thickener have a surprisingly high viscosity. This means that relatively little cationic starch is required to produce compositions with a certain desired viscosity.
De waterige samenstellingen volgens de uitvinding bezitten een watergehalte van bij voorkeur 60 tot 97 gew.%. De pH van de wasverzachtersamenstelling volgens de uitvinding ligt gewoonlijk tussen 1 en 5 en bij voorkeur tussen 2 en 4.The aqueous compositions of the invention have a water content of preferably 60 to 97% by weight. The pH of the fabric softener composition of the invention is usually between 1 and 5 and preferably between 2 and 4.
De gewenste pH kan door middel van zuren ingesteld worden.The desired pH can be adjusted by means of acids.
Methoden voor het vervaardigen van kationogeen zetmeel worden beschreven door D.B. Solarek; Cationic Starches in het boek van O.B. Wurzburg (Ed), Modified Starches: Properties and Uses, CRC Press, Ine., Boca Raton, Florida, 1986, pag.Methods of making cationic starch are described by D.B. Solarek; Cationic Starches in the book by O.B. Wurzburg (Ed), Modified Starches: Properties and Uses, CRC Press, Ine., Boca Raton, Florida, 1986, p.
113-130. Als uitgangsmateriaal voor de vervaardiging van het volgens de uitvinding toe te passen kationogene zetmeel kunnen alle zetmeelsoorten toegepast worden zoals aardappelzetmeel, maïszetmeel, tarwezetmeel, tapioca-zetmeel, erwtenzetmeel en de zetmeelsoorten die een amylopectinegehalte hebben van meer dan 95 gew.% (op droge stof) . Vóór, na of tijdens de kationiseringsreactie kan het zetmeel fysisch, chemisch en/of enzymatisch gemodificeerd worden. De uitdrukking "kationogeen zetmeel" als hierin gebruikt omvat tevens deze additioneel gemodificeerde zetmeelprodukten. De substitutiegraad (DS) van het volgens de uitvinding toe te passen kationogene zetmeel ligt bij voorkeur tussen 0,005 en 0,5 en liefst tussen 0,01 en 0,2. De hoeveelheid volgens de uitvinding toe te passen kationogeen zetmeel (droge stof) ligt bij voorkeur tussen 0,1 en 5 gew.% en liefst tussen 0,2 en 1,5 gew.%, berekend op het gewicht van de vloeibare waterige wasverzachtersamenstelling.113-130. All starches such as potato starch, corn starch, wheat starch, tapioca starch, pea starch and the starches having an amylopectin content of more than 95% by weight (on dry matter) can be used as starting material for the manufacture of the cationic starch to be used according to the invention. ). Before, after or during the cationization reaction, the starch can be modified physically, chemically and / or enzymatically. The term "cationic starch" as used herein also includes these additionally modified starch products. The degree of substitution (DS) of the cationic starch to be used according to the invention is preferably between 0.005 and 0.5 and most preferably between 0.01 and 0.2. The amount of cationic starch (dry matter) to be used according to the invention is preferably between 0.1 and 5% by weight and most preferably between 0.2 and 1.5% by weight, based on the weight of the liquid aqueous fabric softener composition.
De vloeibare waterige wasverzachtersamenstelling kan verder nog diverse hulpstoffen en additieven bevatten zoals geurstoffen, kleurstoffen, conserveermiddelen, elektrolyten, dispergeermiddelen, emulgatoren, vetzuren, vetzuuralcoholen, zouten en niet-ionogene oppervlakte-actieve verbindingen.The liquid aqueous fabric softener composition may further contain various auxiliaries and additives such as fragrances, dyes, preservatives, electrolytes, dispersants, emulsifiers, fatty acids, fatty acid alcohols, salts and non-ionic surfactants.
Het volgens de uitvinding toe te passen kationogene zetmeel wordt bij voorkeur eerst verstijfseld in water, waarna de verkregen zetmeeloplossing (eventueel na afkoeling) onder roeren wordt gemengd met een waterige dispersie van de biologisch afbreekbare wasverzachter. Men kan ook voorverstij fseld kationogeen zetmeel (als droog produkt of na oplossen in water) mengen met de waterige wasverzachter-dispersies.The cationic starch to be used according to the invention is preferably first gelatinized in water, after which the resulting starch solution (optionally after cooling) is mixed with an aqueous dispersion of the biodegradable fabric softener with stirring. It is also possible to mix pre-gelatinized cationic starch (as dry product or after dissolving in water) with the aqueous fabric softener dispersions.
