Description
Sekvestreringsmiddel for vaskemiddel.Sequestering agent for detergent.
Foreliggende oppfinnelse vedrører et sekvestreringsmiddel for vaskemidler som inneholder persalter, og det særegne ved seks-vestreringsmidlet i henhold til oppfinnelsen er at det består av magnesium-glué.oheptomat. The present invention relates to a sequestering agent for detergents containing persalts, and the distinctive feature of the sequestering agent according to the invention is that it consists of magnesium glue.oheptomat.
Man vet at persalter som natriumperborat i husholdnings-vaskemidler, eller hydrogenperoksydholdig vann innen tekstilindustrien, fordelaktig inneholder et stabiliseringsmiddel som styrer spalt-ningen av peroksydforbindelsen, idet man ellers ville iaktta en nedsettelse av blekevirkningen og en kjemisk endring av cellulosefibrene. It is known that persalts such as sodium perborate in household detergents, or hydrogen peroxide-containing water in the textile industry, advantageously contain a stabilizer that controls the splitting of the peroxide compound, otherwise one would observe a reduction in the bleaching effect and a chemical change in the cellulose fibres.
For å avhjelpe disse ulemper har man anvendt magnesiumsilikatTo remedy these disadvantages, magnesium silicate has been used
og man har fordelaktig behandlet magnesiumsilikatet med et organisk komplekserende middel. and the magnesium silicate has advantageously been treated with an organic complexing agent.
Man har tidligere tilsatt vaskemidlene magnesiumsilikat, før eller etter tørking av vaskemidlene. Magnesiumsilikatet tilsatt på denne måte spiller en stabiliserende rolle ved at det hindrer en meget kraftig spaltning av persaltene og spesielt perboratet eller perkarbonatet i vaskeløsningene. Magnesium silicate has previously been added to the detergents, before or after drying the detergents. The magnesium silicate added in this way plays a stabilizing role in that it prevents a very strong decomposition of the persalts and especially the perborate or percarbonate in the washing solutions.
Man kjenner dårlig til mekanismen for denne virkning, men manThe mechanism for this effect is poorly understood, but man
har eksperimentelt fastslått at denne virkning ikke er til-strekkelig i nærvær av bestemte metallkationer som f.eks. av Cu, Ni, Fe eller Mn. have experimentally determined that this effect is not sufficient in the presence of certain metal cations such as e.g. of Cu, Ni, Fe or Mn.
Det er derfor man til vaskemidlene tilsetter et organisk komplekserende middel som natrium-etylendiamintetraacetat eller natrium- That is why an organic complexing agent such as sodium ethylenediaminetetraacetate or sodium
dietylentriaminpentaacetat.diethylene triamine pentaacetate.
Man har imidlertid på nytt fastslått at virkningen ikke er til-strekkelig overfor jern spesielt. However, it has once again been determined that the effect is not sufficient for iron in particular.
Man har iakttatt at fra pH omtrent 8-9 faller den sek;ye.strer-ende evne for EDTA eller DTPA overfor ferriioner hurtig. It has been observed that from a pH of approximately 8-9, the sequestering ability of EDTA or DTPA towards ferric ions falls rapidly.
Man vet'at et overskudd av komplekset Fe+++ EDTA, eller Fe+++ DTPA er skadelig overfor peroksydholdig vann og persalter. It is known that an excess of the complex Fe+++ EDTA, or Fe+++ DTPA is harmful to peroxide-containing water and persalts.
Man har siden lang tid tilbake kjent til at natriumglueonaterIt has long been known that sodium glueonates
og spesielt natriumglueoheptonat virker gunstig for sekyéstrering av jern i alkalisk miljø, og at disse forbindelser er biologisk nedbrytbare, og man har anvendt dem i vaskemidler, men man har også iakttatt at nærværet av peroksydforbindelser som perborater, peroksydholdig vann, perkarbonater, blir disse glueonater meget hurtig oksydert og blir inaktive som sekyjestreringsmidler. ■ and especially sodium glueoheptonate is beneficial for the sequestration of iron in an alkaline environment, and that these compounds are biodegradable, and they have been used in detergents, but it has also been observed that the presence of peroxide compounds such as perborates, peroxide-containing water, percarbonates, these glueonates become very quickly oxidized and become inactive as sequestering agents. ■
Den erkjennelse som ligger til grunn for den foreliggende oppfinnelse er at angjeldende magnesiumglucoheptonat, spesielt det rasemiske, avhjelper de nevnte ulemper. The realization that forms the basis of the present invention is that the magnesium glucoheptonate in question, especially the racemic one, remedies the aforementioned disadvantages.
Fordelaktig innføres som stabiliseringsmiddel magnesiumsilikatMagnesium silicate is advantageously introduced as a stabilizing agent
i molart forhold SiC^/MgO på mellom 1,5 og 3,5. Foretrukket tilsettes også organisk sekvestreringsmiddel fra gruppen av EDTA, DTPA og spesielt deres hydroksylerte derivater. in molar ratio SiC^/MgO of between 1.5 and 3.5. Preferably, an organic sequestering agent from the group of EDTA, DTPA and especially their hydroxylated derivatives is also added.
Forholdet mellom gram atomer. magnesium og antall mol glucoheptanat er foretrukket over 0,5 og er fordelaktig mellom 0,6 og 1,0. The ratio of gram atoms. magnesium and the number of moles of glucoheptanate is preferably above 0.5 and is advantageously between 0.6 and 1.0.
Forholdet mellom gramatomer"magnesium og antall mol organisk sekvestreringsmiddel er likeledes over 0,5 og helst mellom 0,6 The ratio between gram atoms of magnesium and the number of moles of organic sequestering agent is likewise above 0.5 and preferably between 0.6
og 2,0.and 2.0.
Oppfinnelsen er særlig anvendelig ved vaskemidler som inneholder persalter og har følgende sammensetning på vektbasis: The invention is particularly applicable to detergents that contain persalts and have the following composition on a weight basis:
5 til 40 % Na-perborat5 to 40% Na perborate
5 til 40 % STPP5 to 40% STPP
5 til 30 % overflateaktiv bestanddel5 to 30% surfactant
5 til 20 % av et Na-silikat med molforhold Si02/Na20 på mellom 1 og 4. 5 to 20% of a Na silicate with a SiO 2 /Na 2 O molar ratio of between 1 and 4.
Det er spesielt fordelaktig hvis vaskemidlet i henhold til oppfinnelsen inneholder natrium-silik'6'aluminat i vanlige mengder, dvs. 5 til 30 vektprosent. It is particularly advantageous if the detergent according to the invention contains sodium silica'6'aluminate in normal amounts, i.e. 5 to 30 percent by weight.
Foretrukket innføres 0,05 til 5 vektprosent av sekvestreringsmidlet i henhold til oppfinnelsen. Preferably, 0.05 to 5 percent by weight of the sequestering agent according to the invention is introduced.
Sekvestreringsmidlet kan innføres på flere måter i vaskemidlet. The sequestering agent can be introduced into the detergent in several ways.
Ved en enkel utførelsesform innføres sekvestreringsmidlet påIn a simple embodiment, the sequestering agent is introduced on
en bærer, idet blandingen omfatter Mg-sulfat, et organisk sekvestreringsmiddel av gruppen EDTA, DTPA og deres hydroksylerte derivater i form av deres natriumforbindelser, og natrium-glucoheptonat slik at magnesium kan menges i kompleks form, med forholdet gram-atomer: magnesium/molglu.coheptonat på mer enn 0,5 a carrier, the mixture comprising Mg-sulphate, an organic sequestering agent of the EDTA group, DTPA and their hydroxylated derivatives in the form of their sodium compounds, and sodium glucoheptonate so that magnesium can be mixed in complex form, with the ratio gram atoms: magnesium/molglu .coheptonate of more than 0.5
og forholdet gramåtomér magnesium/molsekvestreringsmiddel av gruppen EDTA, DTPA likeledes over 0,5, slik at sekvestrerings-midlene ikke fortrenger Mg i bæreren som fordelaktig ut-gjøres av Mg/silikat i molforhold på mellom 1,5 og 3,5. and the ratio gram-atom magnesium/mole sequestering agent of the group EDTA, DTPA likewise above 0.5, so that the sequestering agents do not displace Mg in the carrier, which advantageously consists of Mg/silicate in a molar ratio of between 1.5 and 3.5.
Man kan likeledes anvende forskjellige bærere, spesielt på basis av silisiumoksyd og silisiumoksydderivater. You can also use different carriers, especially on the basis of silicon oxide and silicon oxide derivatives.
Man kan likeledes fremstille sekvestreringsmidlet in situ i suspensjonen. I dette tilfelle kan sekvestreringsmidlet inn-føres i suspensjonen før avvanning. The sequestering agent can also be prepared in situ in the suspension. In this case, the sequestering agent can be introduced into the suspension before dewatering.

Man gjennomfører ved hjelp av en vaskeinnretning av typen "Terg-O-Tometer" ved 90°C med vann av hårdhet 22° Ch NF T90003 10 vaskinger med prøvestykker av hvit Krefeld-bomull i nærvær av to tilsmussede prøvestykker. Using a "Terg-O-Tometer" washing device at 90°C with water of hardness 22° Ch NF T90003, 10 washes are carried out with test pieces of white Krefeld cotton in the presence of two soiled test pieces.
Rotasjonshastigheten er 100 omdr./minutt. Varigheten av hver vasking er 10 minutter og varigheten av hver skylling er 2 minutter. The rotation speed is 100 rpm. The duration of each wash is 10 minutes and the duration of each rinse is 2 minutes.
Polymerisasjonsgraden (DP) av den vaskede hvite bomull bestemmes i henhold til fransk standard NF T 12005 ved at det som referanse 0 tas magnesiumsilikat med 8,5 % DTPA-Na. 1 sekvestreringsmidlet erstattes de 8,5 % DTPA-Na med 10 % Na glUGoheptonat. DP blir da -230, det vil si at man ikke iakttar noen forbedring men en nedbrytning. The degree of polymerization (DP) of the washed white cotton is determined according to French standard NF T 12005 by taking magnesium silicate with 8.5% DTPA-Na as reference 0. In the sequestering agent, the 8.5% DTPA-Na is replaced by 10% Na glUGoheptonate. DP then becomes -230, which means that no improvement is observed but a degradation.
Man erstatter deretter de 10 % Na-glucoheptonat i rekkefølge med de følgende to blandinger: a) 7 % DTPA-Mg + 3 % magnesiumglucoheptonat ved hjelp av den i det foregående angitte fremstillingsmåte. The 10% Na-glucoheptonate is then replaced in order with the following two mixtures: a) 7% DTPA-Mg + 3% magnesium glucoheptonate by means of the preparation method indicated above.
