Wrexham, Denbighshire, Wales, Philip Alan Gilbert, Wirral, Cheshire, England-England (GB) (71 *) Leitzinger Oy (5U) Detergent Composition - Detergent Composition The present invention relates to a detergent composition comprising 5-30% by weight of orthophosphate as a building material.
Pesuaineseokset sisältävät pääaineosinaan pesuaktiivisia aineita ja runkoaineita. Tavallisin runkoainetyyppi on ollut natriumtripolyfos-faatti, muuta viime vuosina on esitetty, että tällaisten pesuaineiden runkoaaineiden käyttäminen voi johtaa eutrofikaatio-ongelmiin sisävesissä. On ehdotettu, että pesuaineiden runkoaineena voitaisiin .%äyttää muita kuin fosforia sisältäviä aineita tai vaihtoehtoisesti että voitaisiin pienentää fosforin määrää pesuaineseoksessa. Orto-fosfaattimateriaalin käyttö pesuaineiden runkoaineena on jo aikaisemmin ollut tunnettua. Nimitystä ortofosfaattimateriaali käytetään määrittelemään aine, joka antaa ortofosfaatti-ioneja liuokseen, pe-suaineseoksisa tällainen aine on tavallisesti osittain neutralisoidussa muodossa, esim. monovety- tai divetyortofosfaattina. Tavallisesti käytetään natriumsuolaa, mutta on myös mahdollista käyttää kalium- tai ammoniumsuoloja.Detergent mixtures contain detergent active ingredients and builders as their main ingredients. The most common type of aggregate has been sodium tripolyphosphate, and in recent years it has been suggested that the use of aggregates in such detergents can lead to eutrophication problems in inland waters. It has been suggested that non-phosphorus-containing substances could be used as detergent builders or, alternatively, that the amount of phosphorus in the detergent composition could be reduced. The use of ortho-phosphate material as a detergent bulking agent has been known in the past. The term orthophosphate material is used to define a substance that releases orthophosphate ions into solution, in detergent mixtures such a substance is usually in a partially neutralized form, e.g. as a monohydrogen or dihydrogen orthophosphate. Usually a sodium salt is used, but it is also possible to use potassium or ammonium salts.
Nyt on yllättäen havaittu, että ortofosfaattirunkoisten pesuainese- 2 60029 osten, jotka sisältävät aktiivisena aineena alkyylibentseenisulfo-naattia ja/tai alkoholisulfaattia, pesukykyä voidaan parantaa käyttämällä mainitun aktiivisen aineen lisäksi joko ionitonta aktiivista ainetta, esim. etoksyloitua alkoholia, tai vastaavasti alkyyli-eetterisulfaattia. Oletetaan, että tämä toisella aktiivisella aineella aikaansaatu pesukyvyn paraneminen johtuu tästä toisesta aktiivisesta aineesta, joka estää pesuaktiivisen aineen maa-alkalime-tallisuolojen saostumisen. On ymmärrettävä, että maa-alkali-ioneja on läsnä pesuliuoksen valmistamiseen käytetyssä vedessä. Jonkin mekanismin uskotaan saostavan yhdessä tai poistavan alkyylibentseeni-sulfonaattien kalsiumsuolat saostuneisiin kalsiumortofosfaattisuo-loihin liittyen. Kun korvataan jokin määriteltyjen substituentti-luokkien jäsen, estetään aktiivisen aineen irreversiibeli poistuminen pesuliuosjärjestelmästä. Nimitystä "irreversiibeli poistuminen" käytetään, koska aktiivinen aine poistuu liukenemattomana kal-siumsuolana, joka pysyy poissa pesujärjestelmästä vaikkakin kalsiumortof osfaatin saostuminen pienentää kalsiumionikonsentraatiota. Vaikutus on kemiallisesti reversiibeli, mutta ei normaalien pesuproses-sien aikana. Aktiiviset aineet ovat yleensä mukana natrium-, kalium-tai ammoniumsuoloina, mieluummin ensiksi mainittuina.It has now surprisingly been found that the washing performance of orthophosphate-based detergent compositions containing alkyl benzene sulphonate and / or alcohol sulphate as active ingredient can be improved by using, in addition to said active ingredient, either a non-ionic active substance, e.g. ethoxylated alcohol or alkyl ether, respectively. It is believed that this improvement in detergency provided by the second active agent is due to this second active agent, which prevents the precipitation of alkaline earth metal salts of the detergent agent. It is to be understood that alkaline earth ions are present in the water used to prepare the washing solution. One mechanism is believed to co-precipitate or remove the calcium salts of alkylbenzene sulfonates in association with the precipitated calcium orthophosphate salts. Replacing a member of a defined class of substituents prevents irreversible removal of the active agent from the wash solution system. The term "irreversible removal" is used because the active substance is removed as an insoluble calcium salt which remains out of the washing system, although the precipitation of calcium orthophosphate reduces the calcium ion concentration. The effect is chemically reversible, but not during normal washing processes. The active substances are generally present in the form of sodium, potassium or ammonium salts, preferably the former.
Keksinnön mukaiselle pesuaineelle on tunnusomaista se, että se orto-fosfaatin lisäksi sisältää 10-45 paino-% pesuaktiivista ainetta, jossa on alkoholisulfaattia, jonka kaava on R*CH2*S04*M, jossa R on 12-18 hiiliatominen alkyyliryhmä, ja alkoholieetterisulfaattia, jonka kaava on Ri*CH2(C2H40)xS04»M, jossa R^ on 10-16 hiiliatominen alkyyliryhmä, ja x on 1-5, suhteessa 2:1 - 1:10 ja M on alkalimetalli tai ammoniumioni.The detergent according to the invention is characterized in that it contains, in addition to the ortho-phosphate, 10 to 45% by weight of a detergent active ingredient with an alcohol sulphate of the formula R * CH2 * SO4 * M, in which R is an alkyl group having 12 to 18 carbon atoms, and an alcohol ether sulphate, of the formula R 1 * CH 2 (C 2 H 4 O) x SO 4 »M, wherein R 1 is an alkyl group of 10 to 16 carbon atoms, and x is 1 to 5, in a ratio of 2: 1 to 1:10 and M is an alkali metal or ammonium ion.
Valmis seos voi sisältää muita pesuaktiivisia aineita, joita on esim. kuvattu Schwartzin, Perryn ja Berchin kirjoissa "Surface Active Agents & Detergents" voluumit I ja II (julkaisija INterscience).The finished mixture may contain other detergent agents as described, for example, in Schwartz, Perry and Berch, "Surface Active Agents & Detergents" volumes I and II (published by INterscience).
Edullisesti pesuaktiivista aineta on mukana 10 - 25 %. Suositeltavaa on että alkoholisulfaatin alkyyliradikaali sisältää 14-18 hiiliatomia.Preferably 10 to 25% of detergent is present. It is preferred that the alkyl radical of the alcohol sulfate contain from 14 to 18 carbon atoms.
Alkoholisulfaatin suhde alkoholieetterisulfaattiin on 1:1 - 1:3.The ratio of alcohol sulfate to alcohol ether sulfate is 1: 1 to 1: 3.
