Description
(54) CLEANING COMPOSITION
(71) We, UNILEVER LIMITED, a company organised under the laws of
Great Britain. of Unilever House, Blackfriars, London E/C 4, England, do hereby declare the invention for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:- This invention relates to a cleaning composition, and particularly to a cleaning composition suitable for use in the dishwashing area, for washing cups, dishes, glassware, crockery, pots and pans, glazed objects, etc. The invention is, however, especially concerned with a dishwashing composition for use in manual dishwashing operations.
In manual dishwashíng operations, the objects to be cleaned are usually washed in a hand-warm aqueous solution of a suitable dishwashing composition, and subsequently put on a rack and dried with a tea-cloth. During the period between the cleaning and the cloth-drying some of the wash liquor may dry up on the objects and leave spots or streaky films. This can be reduced by rinsing the cleaned objects with running tap water or immersing them in a bowl with clean water, but the film of water on the objects left on the rack may not drain and dry evenly or quickly and the consequence thereof is that they may need to be polished or cloth-dried to prevent spotting. It has already been proposed to improve the "drainage" properties of dishwashing compositions by inclusion of gelatin which allows a "sheeting-off" effect.Objects cleaned with such compositions may, after having been rinsed under running tap water, be left to stand and drain, thus obviating a cloth-drying operation.
It has now been found that the inclusion of a small amount of casein in dishwashing compositions that comprise an active detergent system containing a secondary alkyl sulphonate/sulphate and an alkylethersulphate or a nonionic detergent provides for a dishwashing composition with improved "sheeting-off" properties and improved "drain-dry" properties on rinsing.
The effect found is surprising since casein belongs to quite a different class of proteins than gelatin. Casein is a phosphoprotein whereas gelatin is a scleroprotein.
Certainly the drain-dry effect is not a property that can be attributed to proteins in general. Experiments have shown that a number of protein-types, such as eggalbumin, bovine albumin, A-lactoglobulin, pepsin, fibrinogen and various protein hydrolysates were found ineffective.
Also, apparently certain compatibility and concerted action rules between casein and the active detergent system must be fulfilled in order to provide for a good drain-dry effect in conjunction with a good dishwashing performance.
Though other anionic organic sulphonate or sulphate surface-active compounds e.g. the alkylbenzenesulphonates, olefinsulphonates, primary alkyl sulphates and the primary alkyl sulphonates, can be used in replacement of the secondarv alkyl sulphonate, these actives alone, without the presence of a secondary alkyl sulphonate will not be as compatible with the casein to produce positively a good drain-dry effect as compared to compositions containing a secondary alkyl sulphonate, the proportion of which may be as low as 10 by weight, based on the total composition, in the presence of other anionic organic surface active-agents as stated above. However, it has been found that the secondary alkyl sulphonate can be replaced by the similarly structured compound, i.e. secondary alkyl sulphate, without any loss in performance.
The secondary alkyl sulphonate used in the invention can be obtained by sulphonating C8-C24, preferably C,2~18 alkanes with a suitable sulphonating agent.
and subsequently neutralizing the sulphonic acids to their suitable salts.
Other methods of obtaining secondary alkyl sulphonates are by sulphochlorination or sulphoxidation of alkanes, or by the bisulphite-addition to suitable alkanes. The secondary alkyl sulphonates to be used in the present invention are the alkali metal, ammonium and substituted ammonium salts, thereof, the alkali metal salts, particularly the sodium salts being preferred.
Mixtures of secondary alkyl sulphonates having different chain lengths are also suitable. The secondary alkyl sulphate for use in the present invention may be obtained by reacting C8-C24, preferably C,2~18 olefins with sulphuric acid, or by sulphation of the corresponding secondary alcohols, followed by neutralization. It is used in the form of its alkali metal, ammonium or substituted ammonium salts.
The active detergent system further comprises an alkylethersulphate and/or a nonionic detergent compound.
The alkylethersulphates are salts of the monosulphuric acid esters of C8-C24 primary or secondary, straight or branched chain alcohols, which have been condensed with 1--10 moles of an alkylene oxide, e.g. ethylene oxide and/or propylene oxide. Particularly suitable are the C,2C,8 primary alcohols condensed with from 1--5 moles of ethylene oxide, which have subsequently been sulphated and neutralized.
A typical example thereof is laurylethersulphate containing 3 moles of ethylene oxide: another typical example is a secondary C11-C15 alcohol condensed with 3 moles of ethylene oxide and subsequently sulphated and neutralized.
The salts of the alkylethersulphates are the alkali metal, ammonium, and substituted ammonium salts, again the alkali metal salts, particularly the sodium salts being preferred.
The nonionic detergent actives which can be used in the present invention are generally the alkylene oxide condensation products of primary or secondary, straight or branched chain C8-C24 alcohols, CsC,8 alkyl or dialkyl phenols C5- C24 fatty acid mono- and diamides, and glycols. In general these condensation products contain from 1--30, usually from 3-25 moles of ethylene oxide and/or propylene oxide.
Typical examples of suitable nonionics of the above group are primary C12- C15 alcohols condensed with 7-12 moles of ethylene oxide and secondary C11-C15 alcohols condensed with 9-12 moles of ethylene oxide.
Another group of useful nonionic surfactants which can be used are amine oxides. Amine oxides are reaction products of tertiary amines and hydrogen peroxide or peroxyacids, having the general formula R R, R2 N~O, of which R may be aliphatic. aromatic, heterocyclic, alicyclic or combinations thereof. The amine oxides of interest in the present invention have R being a straight or branched chain aliphatic hydrocarbon radical having 8 to 20 carbon atoms, which may be saturated or unsaturated, and R, and R2 being a methyl-, ethyl-, hydroxymethyl or a hydroxyethyl group.
Typical examples are dodecyldimethylamine oxide and the various fatty acid derived alkyI--R, R2-amine oxides, such as coconut dimethylamine oxide.
Mixtures of several of the above nonionic detergents can also be used, including a mixture of nonionics with a short and a long alkylene oxide chain.
Accordingly the invention provides a dishwashing composition comprising a secondary C8-C24 alkyl sulphonate or sulphate, a C5-C24 alkylethersulphate having 1--10 alkylene oxide groups, and/or a nonionic detergent compound, and casein.
The composition of the invention may further comprise any other active detergent materials without departing from the essence of the invention, such as the water-soluble alkylbenzenesulphonates, olefin sulphonates, primary alkyl sulphonates, and primary alkyl sulphates.
Casein is a known, commercially available, protein obtained from skim milk by acid or enzyme precipitation, a general reference of which can be found in Kirk
Othmer, Encyclopaedia of Chemical Technology 1949, Vol. 3, pages 225-237; and the Encyclopaedia of Polymer Science and Technology 1965, Jnterscience Publishers, Volume 2, pages 859-871. It has found commercial use in various branches of industry.
The casein to be included in the dishwashing composition of the invention can be cr, a59 ,B, y, or whole casein, but for commercial reasons whole casein is preferred. Both acid casein and rennet casein can be used. It can be added as such, dissolved in a small amount of alkali, or as an aqueous solution of commercially available sodium caseinate. The amount of casein to be incorporated in the composition according to the invention is generally from 0.25 to 5 ,. and preferably from I to 3o by weight.
The amounts of secondary alkyl sulphonate or sulphate and (alkylethersulphate+nonionic detergent) are:
generally preferably secondary alkyl sulphonate/sulphate I40 n 5300,, alkylethersulphate
and/or nonionic detergent 140 I 7-0 It is to be understood that the active detergent system always comprises a component (a) comprising a secondary alkyl sulphonate/sulphate, together with a component (b) which is either an alkylethersulphate or a nonionic detergent or both. The weight ratio between the secondary alkyl sulphonate/sulphate and the alkylethersulphate or nonionic detergent will generally be from 5:1 to 1:2 and preferably from 4:1 to 1:1 in the absence of other anionic sulphonate or sulphate type detergents.
In the presence of other anionic sulphonate or sulphate detergents of the type as stated above. these detergents can be grouped in component (a) and the above ratios will apply to component (a) with respect to component (b).
The compositions of the invention may furthermore contain the usual ingredients, commonly incorporated in dishwashing compositions. Such ingredients are hydrotropes, such as ethanol, urea, sodium xylene- and toluenesulphonate, perfumes, colouring materials, opacifiers, preservatives and so on.
It has also been found that the further inclusion of an organo-phosphorus compound as will be defined hereinafter in the composition of the invention improves drain-drying whilst providing for an additional benefit in that the rinsability of these compositions is enhanced, thereby gaining the full benefit of the invention with less rinsing.The organo-phosphorus compound used here can be a phosphate ester or a phosphate, having the general formula R(EO)n(O)rn PO3X2, wherein R is a straight or branched chain alkyl having 8-18 carbon atoms, or a phenylalkyl hydrocarbon chain wherein the alkyl group has 1W18 carbon atoms: (EO) is an ethylene oxide or propylene oxide group; n is a number from 0
10; m=0--1; and X is hydrogen, or an alkali metal, ammonium or substituted ammonium cation.Particularly suitable phosphorus compounds are phosphate esters having the general formula R(EO)nOPO3X2, wherein R is a straight chain or branched chain hydrocarbon radical having 8-18 carbon atoms, preferably I l15 carbon atoms: (EO) is an ethylene oxide or propylene oxide group; n is a number from e10, preferably 3-7: and X is hydrogen, or an alkali metal, ammonium or substituted ammonium cation. A typical example is the sodium salt of the monophosphoric acid ester of a C11-C15 sec. alcohol, condensed with 3 moles of ethylene oxide. The amount of organo-phosphorus compound, when incorporated, is 0.55Dn, preferably 0.5--3.00; by weight of the total composition.
Accordingly in one preferred embodiment of the invention the composition comprising a secondary alkyl sulphonate, an alkylether sulphate or a nonionic
surface active compound includes casein and the above preferred phosphate ester in amounts up to 5% of the total composition.
The composition of the invention may be made in any suitable form, such as powders, aqueous liquids or concentrated non-aqueous liquids. They are preferably, however, in the form of aqueous liquids.
As stated above, the compositions of the invention are particularly suitable for manual dishwashing operations, in which, after cleaning, the cleaned objects are rinsed with running tap water (either hot or cold), or by immersing them in a bowl with clean hot or cold water, and then left to stand to dry. The adhering film of water will rapidly drain or sheet off, and the objects will dry without showing significant spotting or streaking effects.
In the following test the effect of a number of proteins added to the wash bowl-either as a predissolved solution or dispersion-on product performance was examined.
The basic product composition is: sodium secondary C,2 16 alkyl sulphonate 16.70, C gs alcohol/l2 ethylene oxide 8.3', water to 100 /" Six wash solutions of the above product at a concentration of 0.2', vere made.
With each wash solution the following test procedure was followed:
Three plates were washed in the wash solution in the absence of soil rinsed and allowed to dry. Three further plates were treated in the same wash solution following sequential addition of protein (3x0.2 gms to 5 litres of wash liquor).
Finally 3 more plates were treated with no further addition of soil.
Each wash lasted for 2 minutes. followed by a 4 second rinse under the tap and a brief immersion in a rinse bowl containing the same tap water. The temperature of both wash and rinse was about 43 C.
The types of protein materials tested were egg-albumin, bovine albumin, A- lactoglobulin, pepsin, fibrinogen and soluble casein.
All plates washed in the wash solution without protein and with protein other than casein, showed slow draining of the water film and water-hardness spotting and streaks after drying.
Only soluble casein showed a marked beneficial effect on drain-dry performance, even after the first addition to the wash bowl.
The plates washed with the casein-containing wash solution showed an appearance markedly distinct from that of the plates treated otherwise. in that they were substantially free of spotting and streaks.
The invention will now be further illustrated by way of examples.
