Description

Derr foreliggende opfindelse angår en hidtil ukendt håndvaskepasta, fortrinsvis til fjernelse af tilsmudsning med farvestoffer. Håndvaskepastaen ifølge opfindelsen er vandfri og indeholder reduktions-5 midler og et vandfrit oxidationsmiddel, og den er ejendommelig ved, at den som oxidationsmiddel indeholder 5-15 vægt?0 af et natriumperborat, som er overtrukket med siliconolie . i et vægtforhold mellem natriumperborat og siliconeolie på mellem 2:1 og 4:1.The present invention relates to a novel hand-washing paste, preferably for removing staining with dyes. The handwash paste of the invention is anhydrous and contains reducing agents and an anhydrous oxidizing agent, and is characterized in that it contains as an oxidizing agent 5-15 wt.% Of a sodium perborate coated with silicone oil. in a weight ratio of sodium perborate to silicone oil of between 2: 1 and 4: 1.

10 I den tyske patentskrift 1031460 beskrives for første gang en pasta til håndvask, hvor befugtnings-midlet først dannes i brugsøjeblikket. I denne bliver den syre, der er basis for den vaskeaktive substans, på simpel måde indarbejdet i en oliefase på grund 15 af dens olieopløselighed. f.eks. lader den syre, der opstår ved kondensation af fedtsyre med sarkosin, sig indarbejde i en naturlig planteolie, som ricinusolie, idet der til forbedring af konsistensen yderligere kan tilsættes metalsæber. I dette grundmateriale 20 lader en blanding af soda, natriumdithionit og pimpstenspulver sig indarbejde. Disse uorganiske bestanddele bliver omgivet af olie fasen på en sådan mådg at en reaktion med syren under saltdannelse ikke er mulig.10 German Patent Specification 1031460 describes for the first time a hand-washing paste in which the wetting agent is first formed at the moment of use. In this, the acid which is the basis of the detergent active substance is simply incorporated into an oil phase due to its oil solubility. eg. For example, the acid produced by the condensation of fatty acid with sarcosine is incorporated into a natural plant oil, such as castor oil, with the addition of metal soaps to improve the consistency. In this basic material 20 a mixture of soda, sodium dithionite and pumice powder is incorporated. These inorganic constituents are surrounded by the oil phase in such a way that a reaction with the acid during salt formation is not possible.

Selv små mængder vand bliver emulgeret på en sådan 25 måde, at de ikke bevirker en for tidlig igangsætning af reaktionen. Når pastaen påføres hænderne, og der tilføres vand, så sker neutraliseringen under dannelse af det virksomme befugningsmiddel, ligesom udvikling af svovldioxid indtræder.Even small amounts of water are emulsified in such a way that they do not cause premature initiation of the reaction. When the paste is applied to the hands and water is added, the neutralization takes place to form the active wetting agent, just as sulfur dioxide development occurs.

30 Det har nu overraskende vist sig, at den blegende og følgelig den rensende virkning af en vaskepasta med samme sammensætning som i det tyske patentskrift 1031460, som f.eks. indeholder butylglycol, lauridit, emulan, hexylenglycol, fyrrenåleolie, lanolin, 35 triethanolamin, aerosil, pimpstensmel og et vandfrit reduktionsmiddel, som natriumdithionit, kan forøges væsentligt ved, at der samtidig tilblandes granuleret 230 Surprisingly, it has now been found that the bleaching and consequently the purifying effect of a washing paste of the same composition as in German Patent Specification 1031460, e.g. contains butyl glycol, lauridite, emulane, hexylene glycol, pine oil, lanolin, triethanolamine, aerosil, pumice flour and an anhydrous reducing agent such as sodium dithionite can be significantly increased by simultaneously mixing granulated 2

natriumperborat overtrukket med siliconolie, som oxidationsmiddel.sodium perborate coated with silicone oil as the oxidizing agent.

Natriumperboratgranulatet har fortrinsvis en partikkelstørrelse, der svarer til det anvendte 5 pimpsten, hvilken ligger i størrelsesområdet: fra 30 til 60 |.i (DIN normstørrelse ca. G 1/2). Det er nødvendigt først at blande dette natriumperboratgranulat med siliconolie, idet vægt forholdet mellem natriumperborat og siliconolie kan svinge mellem 2 til 1 og 4 til 10 1. Denne blanding blandes derpå grundigt med den anden blanding, der består af et vandfrit befugtnings-middel, et reduktionsmiddelThe sodium perborate granulate preferably has a particle size corresponding to the pumice used, which is in the size range: from 30 to 60 µl (DIN standard size about G 1/2). It is necessary first to mix this sodium perborate granulate with silicone oil, since the weight ratio of sodium perborate to silicone oil can fluctuate between 2 to 1 and 4 to 10 1. This mixture is then thoroughly mixed with the second mixture consisting of an anhydrous wetting agent, a reducing agent

og de ovenfor angivne bestanddele. Som reduktions-middel egner sig f.eks. pyrokatekin, natriumsulfit 15 eller -bisulfit, men specielt natriumdithionit. Iand the constituents listed above. As a reducing agent, e.g. pyrocatechin, sodium sulfite or bisulfite, but especially sodium dithionite. IN

den på denne måde fremstillede pasta kan reduktions-midlet ikke reagere med oxidationsmidlet natriumperborat. Denne pasta er uindskrænket lagerbest.andig;the paste thus prepared cannot react with the oxidizing agent sodium perborate. This paste is unlimited in stock;

f If I

den taber selv efter lang lagringstid ikke sine 20 reducerende og oxiderende egenskaber. Dersom denne pasta benyttes til vask, så træder først den reducerende og derefter, tidsmæssigt forskudt, den oxiderende egenskab i forgrunden.it does not lose its 20 reducing and oxidizing properties even after long storage. If this paste is used for washing, first the reducing agent and then, temporarily offset, the oxidizing property comes into the foreground.

Det kunne ved vaskeprocessen forventes, at 25 reduktionsmidlet i første række reagerer med oxidationsmidlet på grund af vandets opløsende virkning, forstærket af befugtningsmidlets virkning, og at begge stoffer derefter gensidigt neutraliserer hinanden og derved i stedet for at have en rensende, hen-30 holdsvis blegende virkning, fælder ud på huden eller stoffet. Men det har faktisk vist sig, at reduktionsmidlet ved vaskeprocessen først indvirker på den genstand, der skal renses, og at oxidationsmidlet først senere, efter ca. 2 til 5 minutters forløb, 35 bliver fuldt virksomt.In the washing process, it could be expected that the reducing agent reacts primarily with the oxidizing agent due to the dissolving effect of the water, enhanced by the effect of the wetting agent, and that both substances then mutually neutralize each other and thus instead of a purifying, respectively bleaching effect, precipitates on the skin or substance. But it has actually been found that the reducing agent in the washing process first affects the object to be purified and that the oxidizing agent only later, after approx. 2 to 5 minutes, 35 become fully operational.

Den dobbelte rensevirkning af pastaen ifølge opfindelsen til håndvask er af stor betydning, f.eks.The double cleaning effect of the paste according to the invention for hand washing is of great importance, e.g.
