Description
~22~5~ C 83~ (R) DETERGENT BLEACH COMPOSITIONS
This invention relates to detergent bleach compositions comprising a peroxyacid as the bleach component, which are particularly, but not essentially adapted for fabric washing.
Detergent bleach compositions comprising a peroxyacid are known in the art.
It is also known to incorporate a bleach system comprising a combination of a per-compound such as sodium perorate and a peroxyacid precursor activator) which forms a peroxyacid in situ. There are definite advantages in using a peroxyacid over said precursor bleach system which only generates the peroxyacid from the reaction of the per-compound and the activator it solution, because a peroxyacid purse does not suffer from the relatively low lo efficiency of peroxyacid generation and bleaching which may by due to a deleterious side reaction taking place between the peroxyacid formed and the per compound in the wash/bleach solution, resulting in lower peroxyacid yields. Bleach systems comprising a per compound and an activator therefore requires proper peroxyacid stabilizing agent which should inhibit said side reaction, such as disclosed in US Patent 4225452, in order to achieve a satisfactory pursued yield. tlowe~er peroxyacid bleaching is poor a temperatures below 40C.
With the increasing trend of saving energy, housewives are becoming more and more energy-con~cious and have gradually changed their washing habit towards lower wash-temperatures. Today a major proportion of housewives are I washing also their white laundry using the 60C wa~h~cycle~
A considerable saving of energy would be obtained if washing habits could be further shifted towards cooler and cold water washing e . g. below 40C, also for whites. There it thoroughfares a continuous desire from the part of ray 2265~2 C 832 (R) ala investigators to find ways of improving the bleaching action of bleach systems.
It is an object of the present invention to improve the bleaching performance of peroxyacids and to provide detergent bleach compositions comprising a peroxyacid having improved bleaching performance at lower temperatures.
It is known that heavy metals under certain Cantonese can catalyze the bleaching action of hydrogen peroxide compounds. US Patent 3.156.654 discloses the bleach activity improvement of peroxide compounds by using copper or cobalt ions together with a special type of chelating agents, such as pardon carboxylic acids.
It has now surprisingly been found that in the substantial absence of hydrogen peroxide and in the presence of a sequestrant builder the bleaching performance of certain peroxyacids i.e. parasitic acid, mono-peroxypht?nalic acid 2Q and monomers hate, can be improved by the addition of trace levels of manganese (II) ions. Absence of hydrogen peroxide and the presence of a seques-trant builder are essential conditions for the manganese (II) ion to exert its catalysis action on said peroxyacids.
US Patent 3 532 634 discloses bleachinc3 compositions comprising a per salt, an activator, a transition metal and a chelating agent having a first complex formation constant with the transition metal ion ox log 2 to about log 10 at about 20C.
The prevent invention has the advantage over and is distinct from this system of the art in that it uses a peroxyacid in the absence of hydrogen peroxide, and without the need of said special chelating agent.
C 832 (R) I
The manganese (II) ions added for improving the bleach performance of the peroxyacid according to the invention can be derived from any water soluble manganese (II) salt, such as manganese sulfite or manganese chloride, or from any manganese compound which delivers manganese (II) ions in aqueous solution.
By trace levels it is meant here manganese (II) ion concern-tractions in the wash/ble~ch solution within the range of from about Owl to 1 parts per million. These correspond roughly to a manganese (II) ion content in the detergent bleach composition of ablate 0.005 to 0.1~ by weight.
Any sequestrant builder can be used according to the invention, be it inorganic or organic in nature. An alkali-metal citrate, nitriiotriacetate, ethylenediaminetetra acetate, or an alkali metal triphosp~late may for example be used as the sequestrant builder. A preferred sequestrant builder is sodium or potassium triphosphate.
Accordingly the invention provides a built detergent bleach composition comprising a se~uestrant builder, a proxy-acid selected from the group consisting of peracetic-acid, mono-peroxyphthalic acid, monopersulphate, and water soluble salts thereof, and from 0.00~ to 0.1~ by weight of I manganese (II) ions in the substantial absence of hydrogen peroxide.
Preferably the manganese IT compound in the composition is protected against direct contact with the peroxyacid to avoid premature reaction prior to its point of use.
In practice the composition of the invention will comprise from about 5 to 60~ by weight of the sequestrant builder.
The amount of peroxyacid i.e. peracetic-acid, mono-peroxy-phthalic acid or l~nopersulp~late in ye cons position will normally be in the range of from 1 to So by weight, preferably from to 10% by weight.
C 832 (R) Preferably the mono-peroxyphthalic acid is use in the form of its stable magnesium salt, such as it described in European Patent Application 0027146 and 00~7693 and having the formula:
_ _ ~C03H 2 My As the monopersulphate, the commercially available potassium ~onopersulphate is preferably used.
The detergent bleach composition of the invention usually contains a surface active agent, generally in an amount of from about 2% to 50% by weight, preferably from I 30~ by weight. The surface active agent can be anionic, non ionic, zwitterionic or cat ionic in nature or mixtures of such agents.

Water-solubility can be achieved by using alkali metal, ammonium, or alkanolamine cations; sodium is preferred.
Preferred non ionic surfactants are water-soluble compounds produced by the condensation of ethylene oxide with a hydrophobic compound such as an alcohol, alkyd phenol, polypropoxy glycol, or polypropoxy ethylene Damon.
Especially preferred polyethoxy alcohols are the condemn-station product of 1 to 30 mole of ethylene oxide with 1 mow of branched or straight chain, primary or secondary aliphatic alcohol having from about 8 to about I carbon atoms more especially 1 to 6 moles of ethylene oxide condensed with 1 mow of straight or branched chain, primary or secondary aliphatic alcohol having from about 10 to about I carbon atoms; certain species of poly-ethoxy alcohol are commercially available under the trade-names of "Nodular, "Synperonic"~ and "Tergitol"R, which are registered Trade Marks.
Preferred zwitterionic surfactants are water-soluble derivatives of aliphatic qua ternary ammonium, phosphonium and sulphonium cat ionic compounds in which the aliphatic moieties can be straight or branched, and wherein one of the aliphatic substituents contains from about to 18 carbon atoms and owns contains an anionic water-solubi}izing group, especially alXyldimethyl-propan~sulphonates and I C 832 (R) alkyldimethyl-ammoniohydroxy-propane-sulphonates wherein thy alkyd group in both types contains from about 1 to 18 carbon atoms.
