The present invention provides pourable, aqueous detergent and bleach compositions containing a linear alkyl benzene sulphonate, an ethoxylated fatty alcohol and a suspended peroxydicarboxylic acid, e.g. diperoxydodecanedioic acid, the pH of the compositions being set to 3,5 to 4,1.
Description
~2~
Pourable detergent and bleach composition The inventlon relates to a pourable, aqueous detergent and bleach composition containing an anionic surfactant, a non-ionic sur-factant and a suspended organlc per compound.
A composition of the above type is disclosed in Netherlands Patent Specification No. 276 283. Over the detergent and bleach compositions which are in a form varying from powdered to granular as widely used in actual practice a liquid composition of the type indicated above has great advantages as re~gards preparation and use. Its preparation does not require cost in-crea~ing shaping steps and its liquid form contributes to ease of handling and dlspensing and does away wlth dusting problems.
The above-mentioned Netherlands Patent Specification proposes as bleaching component suspended organic per compounds of the general formula R - O - O - Rl, where R and ~' represent organlc radlcals; moreover, the pH of the compositions described should be at least 7 and preference is given to alkaline reacting com-positions. To these compositions, however, there is the disad-vantage that they are not stable under storage conditions prevailing in actual practice, i.e. there occurs an unacceptable loss of active oxygen. Therefore, these compositions have not found acceptance in actual practlce.
The invention envisage~ eliminating this drawbac~. The compo-sition according to the invention is characterized in that the anionic surfactant is a linear alkyl ben2ene sulphonate, the non-ionic surfactant an ethoxylated fatty alcohol and the organic per compound an aliphatic peroxydicarboxylic acid containlng 8 to 13 carbon atoms, the pH of the compositlon being set to 3,5 to 4,1.
The European Patent Application No. 0 160 342 published on November 6, 1985 discloses liquid, aqueous bleaching compositions having a pH in the range of from 2 to 5 and containing an alkyl benzene sulphonate, an ethoxylated fatty alcohol, a suspended peroxy acid and an electrolyte; Examples IV and V in it disclose compositions havlng a pH of 4,5. Aslde from the fact that the compositions according to the present invention are not disclosed ~ ~.
in said European Patent Application, the present compositions display better storage stabllity as compared with the composi-tions according to said Application. Thi~ is demonstrated in the Example~ below.
The present composition ls storage stable, i.e. after 2 weeks' storage at 40VC it has entirely or practically entirely retained its active oxygen content. The pourability of the present com-posltion may be set in accordance with any particular need. For practical purposes the viscosity of the composition, measured with a Brookfield rotational viscometer (RV type; 20 rpm) at 20~C, is between 1 and 1200 m Pa.s and preferably between 50 and 500 m Pa.s.
The linear al~yl benzene sulphonate and the ethoxylated fatty alcohol to be contained in the present composition are the sub-stances that are also normally used in detergent compositions.
Preferred linear alkyl benzene sulphonates are those having 11 to 14 carbon atom~ in the alkyl chaln. As ~uitable ethoxylated fatty alcohols there are mentioned ethoxylated Cg-C~8 alcohols having an avera~e degree of ethoxylation from 3 to 15.
The amounts of the surfactants to be used may vary with the desired pourabillty. The composition according to the invention generally contains 2 to 20~ by weight of the linear alkyl benzene sulphonate and S to 30~ by weight of the ethoxylated fatty alcohol, calculated on the weight of the composition.
The bleaching agent to be used according to the invention is an aliphatic peroxydicar~oxylic acid containing 8 to 13 carbon atoms. The term peroxydicarboxylic acid as u~ed here refers to both a monoperoxydicarboxylic acld and a diperoxydlcarboxyllc acid. Use also may be made of mixtures of these peraclds or com-binations of peracids of different chain lengths. It is preferred that the peroxydicarboxylic acid to be used should substantially consist of a diperoxydicarboxylic acid. As examples of the dl-peroxydicarboxylic acids according to the invention may be men-tioned 1,12-diperoxydodecanedioic acid and 1,13-dlperoxytri-decanediolc acid. Partlcularly preferred is 1,12-dlperoxy-dodecanedioic acid ~referred to hereinafter as DPDA). The amountof peroxydicarboxylic acid to be used in the composition according to the inventlon ls generally such that the composi-tion, calculated on the weight thereof, contains active oxygen in an amount ranging between 0,1 and 4% by weight, preferably between 0,1 and 3% by weight.
To prevent sedimentation of the suspended peroxydicarboxylic acid particles their average size is advantageously chosen between 1 and 100 microns.
The peroxydicarboxyllc acids are compounds that are known in themselves and may be prepared by reacting a dicarboxyllc acid with hydrogen peroxide under the influence of sulphuric acid.
Of importance is the quality of the water to be used in the present composition in order to obtain satisfactory storage stability. Favourable results may be obtained wlth bidistilled water or with deionlzed water.
It will be of advantage also to lncorporate a cequestering agent ln the composltlon for the purpo~e of complexlng metal lons, the presence of which may cause decomposltlon of the peroxydlcar-boxyllc acid. As examples of these sequestering agents, which must not be sensltive to the oxidative actlon of the peracld, may be mentioned dipicollnic acid, hydroxyethylidene di-phosphonic acid, alkali metal pyrophosphate and phosphonic acid.
The amount of sequestering agent that may be used in the present composition is generally in the range of O to 1% by welght, preferably 0,01 to 1% by welght, calculated on the weight of the composition.
The pH of the composltlon is of great importance. It should be set to 3,5 to 4,1. At a pH higher than 4,1 the storage stabllity of the composition obtained will dlminisht at a pH lower than 3,5 the compositlon obtalned wlll be less suitable for washlng and bleaching purposes because of a too low pH of the wash liquor upon dilution with water in, for lnstance, a washing machlne. It has been found that the present composltlon, ln ~plte of lts dls-playing a slightly acidic reactlon upon dilutlon wlth water, can be very effectively used ln the treatment of dlrty washlng. This is surprising in that it had up to now been generally assumed that for this purpose neutral to alkaline conditions are required.
The present composition may still contain various commonly applied additives. Examples of such additives include dirt sus-pending agents, fluorescent and optical brighteners or whitening agents, perfumes and hydrotopic substances. The choice thereof is, of course, dependent on the desired properties of the com-position and on the compatibility with the other constituents. In this connection it should be noted that because of the oxidative action of the peroxydicarboxylic acid some additives, such as enzymes and particular oxidation sensitive brighteners or whitening agents cannot be incorporated as such in the present composition. However, such substances may previously be provided with a suitable coating, which may be in the form of, for in-stance, a solid detergent-active material which dissolves during the washing stage, after which its incorporation in the compo-sition ls no longer objectlonable.
The present compositlon can be prepared in a slmple manner by adding finely divided peroxydicarboxylic acid, with stirring, to an acidified (pH about 21 mixture in water of the anionic and the non-ionic surfactant and any other constituents, after which the pH of the resulting compo~ition is set to the desired value with, say, sodium hydroxide.
The following examples serve to illustrate the invention. All percentages therein are by weight.
ExamPle 1 Three compositions according to the invention were tested for loss of active oxygen during storage. The table below gives the constituents in percentages and the relevant properties of the compositions and the test results. In addition the table gives the test results of a comparative test conducted on a composltion according to Example 4 of Netherlands Patent Specification No.

The test results show that the compositions according to the in-vention display satisfactory storage stability at 40~C. At this temperature prior art composition A was subject to total decom-position, which was moreover attended with severe froth formlng.
It appears from the test results that also at 32~C composition A
shows poor storage stability.
Into several compositions corresponding to composition 3 a number of additives were incorporated after which the storage stability was determined in the same way as described above. Use was made of the following additives in amounts given in brackets:
- methylhydroxypropyl cellulose (1%) - optical brightener ATS-X~M a commercial product of Ciba Geigy (0,15%) ~2~ 8`
- perfumes TurboTM LaneaTMand KalifaTM Commercial products of Naarden Chemie Int. Holland B.V. (0,3%).
After 1 month's storage at 40VC all these compositions showed a loss of active oxygen of only a few per cent.
Examp:Le 2 of the Compositlon 3 described in Example 1 an amount of 120 ml was tested under practical conditions for its capability of re-moving ~tains and dirty spots from domestic laundry. Comparative tests were carried out on recommended portions of two commer-cially available compositions, which are referred to hereinafter as Composition B and Composition C. Composition B was a liquid detergent concentrate containing about 37~ of water, about 40% of surfactants and also enzymes and other substances, such as optical whitener; of this composition 120 ml were used. Compo-sition C was a powdered detergent and bleach agent containing about 14% of surfactants, about 19~ of polyphosphate, about 15%
of sodium aluminium silicate, about 23% of sodium sulphate, about 9% of sodium perborate.4H20, about 4% of tetraacetyl ethylene diamine and also enzymes and other additlves~ of this composition 131 g were used.
In each test in all 216 articles, including tea towels, sheets, pillow cases and underwear, were washed in an AEG-Turnamat washer with tap water of 9~ G~. The maximum washing temperature was 62JC, the total washing time, includlng heating up, was 59 minutes and the amount of water admitted 19 litres. Following the washing process the washing was rinsed with 5 x 17 litres of cold water and dried. Subsequently, the washing was rated by a panel by counting the number of clean fourth parts of the tea towels, sheets and pillow cases. Both sides were rated, so that the rating of a perfectly clean article was 8 point~. The underwear was compared with totally clean underwear , the rating for totally clean underwear being 8 points and for less clean under-wear between 0 and 8.
.
~C~31 2~LrJ,'~
For each of the three compositions tested the ratings of 12 tests were averaged. For the composition according to the inventlon the rating was 6,8, for Composition B it was 6,5 and for Composition C 6,,9. These results show that the effectivene~s of the compo-sltion according to the lnvention is excellent.
Repeating the above tests at a maximum washing temperature of 40~C resulted in similar ratings.
ExamPle 3 In thls Example compositions according to the invention are com-pared with compositions according to European Patent Application No. 0 160 342 as regards storage stability. A composïtion was prepared containing 100 g of sodium dodecyl benzene sulphonate (85%, the remainder substantially consisting of sodium sulphate and some sodium chloride), 100 g of ethoxylated ~7,5 EO) Cl2-Cl4 fatty alcohol, S g of Dequest 2010, 243 g of DPDA ~aqueous paste with an active oxygen content of 5,1%), 557 g of water.
This composition was divided into several portions whlch were each set to a dlfferent pH. Of the resulting compositlons the storage stability was determined by measuring the percentage of actlve oxygen remaining after storage at 40~C durlng 1, 3 and 4 weeks. The results are tabulated below.
