Varastostabiloitu pesuaine, jonka valkaisuoininaisuuksia on tehostettu Tåmå keksinto koskee varastostabiloitua pesuainet-5 ta, jonka valkaisuoininaisuuksia on tehostettu, erityisesti talouspesuainetta valko- ja kirjopyykille, joka pesuaine sisaltaa 2-20 paino-% detergenttejå ja muita apuaineita, mukaanluettuna tayteaineet, ja jota kaytetaan pesukoneis-sa. ... ..The present invention relates to a stock-stabilized detergent with enhanced bleaching properties, in particular a household detergent for laundry and laundry, which detergent contains 2-20% by weight of detergents and other auxiliaries, including detergents. you. ... ..
10 Koska pesukoneiden kåytto yleistyy jatkuvasti, tay- tyy myos pesuaineen ominaisuudet sopeuttaa muuttuneisiin olosuhteisiin.10 As the use of washing machines is becoming more common, the properties of the detergent must also be adapted to the changed conditions.
Uudet pesuaineet ovat sen vuoksi yhdistelmiå deter-genteista, jotka toimivat pesuaktiivisina aineina, valkai-15 suaineista ja pesutehoa voimistavista lisaaineista, joita nimitetåån builderaineiksi, jotka ensinnakin pehmentavat pesuvetta ja toisaalta estavat epaorgaanisia suoloja saos-tumasta pestavien tekstiilien pinnalle ja saavat siten aikaan pestyjen tekstiilien pehmeån tunnun.The new detergents are therefore combinations of detergents which act as detergents, bleaches and detergents, which are called builder agents. feel.
20 Erittain hyvia builderaineita ovat polymeroidut fosfaatit, edullisesti natriumtripolyfosfaatti.Particularly good builder materials are polymerized phosphates, preferably sodium tripolyphosphate.
Kotitalouksien jatevesien sisaltåmien fosfaattien aiheuttaman jokien ja jårvien rehevoitymisvaaran vuoksi builderaineiksi on ehdotettu zeoliitteja.Due to the risk of eutrophication of rivers and lakes caused by phosphates in domestic wastewater, zeolites have been proposed as builder materials.
. 25 On osoittautunut, ettå .kåytettaessa zeoliitteja builderaineina pyykki menettaa useiden pesukertojen jal-keen toivotun pehmeyden. Lisaksi valmistuksen ja kåyton vålisena varastointiaikana pesuaine menettaa osittain pe-sutehoansa valkaisuaineen hajoamisen vuoksi.. It has been shown that when zeolites are used as builder, the laundry loses the desired softness after several washes. In addition, during storage between manufacture and use, the detergent loses some of its detergent effect due to the decomposition of the bleach.
30 Julkaisussa DE-3 416 669 Al on sen vuoksi ehdotet tu, etta pesuaineeseen lisatåån 1-20 paino-% kiteista kerrossilikaattia tai alkaalisilikaattia. Taten saatiin pyykkiin pehmea tuntu myos kåytettaessa zeoliitteja builder ina, pesuaineen varastointistabiilisuuteen tållå ei 35 kuitenkaan voitu vaikuttaa.DE-3 416 669 A1 therefore proposes that 1-20% by weight of crystalline layered silicate or alkali metal silicate is added to the detergent. Tate also got a soft feel on the laundry when using zeolites as a builder, however, the storage stability of the detergent could not be affected.
2 ' 923292 '92329
Taman vuoksi esilla olevan keksinnon tehtåvåna oli aikaansaada pesuaine, jonka varastointistabiilisuus on pa-rempi ja jonka valkaisuominaisuuksia on tehostettu ja joka samanaikaisesti sailyttåå pestyjen tekstiilien pehmean 5 tunnun.Therefore, it was an object of the present invention to provide a detergent which has better storage stability and has enhanced bleaching properties, while at the same time preserving the soft feel of the washed textiles.
Yllåttåvåsti havaittiin, etta varastostabiloitu pesuaine, jonka valkaisuominaisuuksia on tehostettu, saa-daan aikaan, kun pesuaine sisaltaa builderaineena 10 - 50 paino-%, edullisesti 20-35 paino-% kiteista kerrossili-10 kaattia, jonka yleinen kaava onIt has surprisingly been found that a stock-stabilized detergent with enhanced bleaching properties is obtained when the detergent contains 10 to 50% by weight, preferably 20 to 35% by weight, of crystalline layered silicate having the general formula as a builder.
NaMSi205 jossa M = Na tai H, ja valkaisuainetta, jolloin valkaisu-15 aineen måarå on mitattu siten, ettå pesuaine sisaltaa 0,5-4 paino-%, edullisesti 1,0 - 2,5 paino-% pesuaktii- vista happea (AVOX).NaMSi 2 O 5 where M = Na or H, and a bleaching agent, wherein the amount of bleaching agent is measured such that the detergent contains 0.5-4% by weight, preferably 1.0-2.5% by weight of detergent active oxygen (AVOX ).
Erittain hyvia tuloksia saatiin kun kiteinen ker-rossilikaatti vastasi Na2si3o5:n i-muotoa.Particularly good results were obtained when the crystalline layer silicate corresponded to the i-form of Na 2 Si 3 O 5.
20 a) Keksinnon mukaiselle pesuaineelle voi lisaksi edullisesti olla tunnusomaista, etta kiteisen kerrossili-kaatin partikkelien halkaisija vaihtelee vålillå 0,01 -1000 ^m, edullisesti valilla 1-20 ^m; b) kiteisen kerrossilikaatin ioninvaihtokapasiteet-25 ti on valilla 400 - 1200 mmol Na+/100 g vedetonta ainetta; c) valkaisuaine on natriumperboraattitetrahydraat-ti, natriumperboraattimonohydraatti ja/tai natriumperkar-bonaatti; d) se sisaltaa lisabuilderaineina epåorgaanisia 30 ja/tai orgaanisia fosfaatteja, boraatteja, sitraatteja, glukonaatteja, nitrilotrietikkahappoa (NTA) ja/tai imino-diasetaatteja aina 20 paino-%:iin asti; e) se koostuu agglomeraattipartikkeleista, joiden part ikke likoko on valilla 0,25 - 2,5 mm, ja on valmistettu 35 ruiskutussumusekoitusprosessilla;A) In addition, the detergent according to the invention can advantageously be characterized in that the particle diameter of the crystalline layered silicate varies between 0.01 and 1000 μm, preferably between 1 and 20 μm; b) the ion exchange capacities of the crystalline layered silicate are between 400 and 1200 mmol Na + / 100 g anhydrous substance; c) the bleaching agent is sodium perborate tetrahydrate, sodium perborate monohydrate and / or sodium percarbonate; (d) it contains up to 20% by weight of inorganic phosphates, borates, citrates, gluconates, nitrilotriacetic acid (NTA) and / or iminodiacetates as additional builder substances; e) it consists of agglomerate particles with a particle size between 0.25 and 2.5 mm and has been produced by a 35 spray mist mixing process;
