The members are as Contained in the European Patent Office EDP ile on HENKEL KGaA Dr. Wa/Sk 07.07.1989 Patent Application D 7813-1 EP A licuid non-phosphate deterQent of high alkalinity Laundry detergents for institutional laundries differ considerably in their composition from those typically used in the home. On the one hand, softened water, i.e. Ca- and Mg-free water, is generally used in institutional laundries. On the other hand, institutional laundry detergents often contain highly alkaline builder salts and alkalis, such as sodium metasilicate and sodium hydroxide, which although they can be safely handled by the expert are unadvisable in the home for safety reasons. These highly alkaline constituents can in turn interact with the surfactants typically present, particularly nonionics of the alkyl polyglycol ether type, and can decompose them to a greater or lesser extent in the event of prolonged storage together. These problems exist in particular in the case of liquid concentrates and products which are intended for the preparation of concentrated stock solutions and in whose case the decomposing effect is particularly intensive through lack of spatial separation between surfactant and alkali component. Highly alkaline liquid products and stock solutions have the advantage over powder-form preparations of the same composition that they are dust free and, in particular, can be automatically dispensed and hence pose no operating problems.
Another aspect is the almost exclusive use of surfactants which can be obtained from natural, i.e. renewable, "I V ir D 7813-1 EP 2 raw materials and which are distinguished by complete and rapid biodegradability in the wastewater.
In addition, detergents of the type in question should not produce troublesome quantities of foam either in the main wash cycle or in the final rinse cycle. Since standard foam inhibitors, such as polysiloxanes and paraffin hydrocarbons, undergo losses of effect when dispersed in liquid detergents or, in the case of polysiloxanes, are decomposed by alkali, the surfactant component must itself be low-foaming.
The present invention, by which these problems; are solved, relates to a liquid, aqueous, non-phosphate detergent concentrate containing 5 to 20% by weight of a nonionic surfactant component 15 to 40% by weight of a builder component up to 3% by weight of other nonsurfactant and non-builder detergent constituents and water (balance to 100% by weight), characterized in that the components have the following composition, based on the detergent: Al) 4 to 20% by weight of an alkyl glucoside corresponding to formula I

RECHERCHENBERICHT
OBER DIE INTERNATIONALE PATENTANMELDUNG NR. EP 890137 SA 32402 In ditem Anhang sind die Mitglieder der Patentfamilien der im obengenannten internationalen Recherchenhericht angerdhrt4en Patentdokumente angegeben.
Die Angben her die Familiemitglieder entsrechen dem Stand der Datei de Fmrnnchn D 7813-1 EP 3 constituents (B3 B4) is from 3 to 12% by weight.
The detergent preferably contains the individual components in the following quantities: Al) 5 to 12 by weight A2) 0.5 to 1.5 by weight Bl) 6 to 15 by weight B2) 0.5 to 3 by weight B3) 3 to 10 by weight B4) 0.2 to 2 by weight Component (Al) consists of alkyl glucosides or alkyl oligoglucosides of the type described, for example, in US- PSS 3,547,828, 3,772,269 and 3,839,318. They are obtainable by reaction of glucose or depolymerized starch and alcohols containing C 8 alkyl groups in the presence or absence of lower alcohols or glycols, such as butanol or propylene glycol, and acidic acetalization catalysts.
Alcohols or mixtures of alcohols obtained from native fats, such as coconut oil or palm kernel oil, are preferably used as the fatty alcohols. Examples are octyl, decyl, lauryl and myristyl alcohol and also mixtures thereof. Alternatively, it is also possible to use alkyl glucosides which are derived from oxoalcohols and which, in addition to linear alcohols, also contain alcohols methyl-branched in the 2-position in admixture or an even and/or odd number of i C atoms in the alkyl chain.
Examples are octyl, nonyl, decyl, undecyl, dodecyl and tridecyl alcohol and also mixtures thereof. R is preferably a C 812 alkyl group and more especially a 0 alkyl group. In the reaction of the glucose or glucose-containing starch degradation products with the alcohols, the glucose is partly oligomerized in the presence of acidic acetalization catalysts, resulting in the formation of mixtures of alkyl monoglucosides and alkylol oligoglucosides. The parameter x in formula I thus represents an average degree of oligomerization and is preferably from Z 4,V D 7813-1 EP 4 1.3 to 3. Mixtures such as these are meant where alkyl glucosides are mentioned generally in the context of the invention.
From their production, the alkyl glucosides still contain small quantities of free fatty alcohol and glucose.
Alkyl glucosides containing less than 5% by weight and, more especially, less than 2% by weight fatty alcohols (based on alkyl glucoside) are preferably used.
In addition to the alkyl glucosides, the detergents may optionally contain nonionic surfactants of the ethoxylated fatty alcohol and oxoalcohol type containing 12 to 18 C atoms and 5 to 10 ethylene polyglycol ether groups (EO) as component Suitable nonionic surfactants of this type are, for example, ethoxylates derived from coconut oil, tallow or palm kernel oil fatty alcohols having an HLB or ym-iove..
value of mur= than 121 for example from 13 to 18, and corresponding ethoxylates of oxoalcohols containing 12 to 16 C atoms and 6 to 8 EO groups.
The builder component consists of sodium hydroxide (constituent Bl), sodium silicate (constituent B2) and sequestering polyanionic salts derived from nitrilotriacetic acid (NTA) and, optionally, phosphonic acids (constituent B3 and B4).
In the sodium silicate, the ratio of Na 2 O to SiO 2 4 may be from 1:1 (metasilicate) to 1:3.4 (waterglass). In detergents containing relatively small amounts of sodium hydroxide, metasilicate is preferably used in the interests of high alkalinity whereas, in detergents having relatively high contents of sodium hydroxide, the sodium silicate may consist predominantly or completely of waterglass.
The NTA is present in the form of the trisodium salt, the quantitative calculation also being based on this form.
The NTA content is preferably from 5 to 10% by weight.
The phosphonate is primarily the sodium salt of 1hydroxyethane-1,1-diphosphonic acid (HEDP). The quantita- -os- 'N
I
I
D 7813-1 EP tive calculation is based on the tetrasodium salt. It is also possible to use the sodium salts of aminotrimethylene phosphonic acid (ATMP), ethylenediamine tetramethylene phosphonic acid (EDTMP), diethylenetriamine pentamethylene phosphonic acid (DTPMP) and higher homologs thereof, although EDTMP is less preferred on account of its as yet unclear function in the wastewater. Their quantitative calculation is based on neutrally reacting sodium salts (Na 3 salt in the case of ATMP, Na 5 salt in the case of EDTMP, Na 6 salt in the case of DTPMP). The sum of components B3 B4 is from 3 to 12% by weight and preferably from 6 to 11% by weight.
In addition to the constituents mentioned above, the detergents may contain other non-surfactant and non-builder constituents, including optical brighteners in quantities of up to 1% by weight and preferably from 0.05 to 0.3% by weight. Examples of optical brighteners are derivatives of bis-(triazinylamino)-sti'bene disulfonic acid, for example the sodium salt of 4,4'-bis-(2-anilino-4-morpholino-l,3,5triazin-6-ylamino)-stilbene-2,2'-disulfonic acid and of the chlorinated diphenyl distyryl sulfonic acids.
Other optional constituents are enzymes, fragrances, dyes, hydrotropes and water-miscible solvents. Suitable hydrotropes are, for example, toluenesulfonate, xylenesulfonate and cumenesulfonate, in each case in the form of the sodium salts. Suitable solvents are, for example, ethanol, propanol, isopropanol and also ether alcohols, such as diglycol, and C1.
3 monoalkyl ethers of C2- 4 diols. The hydrotropes may be present in quantities of up to 6% by weight while the alcohols or ether alcohols may be present in quantities of up to 10% by weight. The detergents may also contain neutral salts, such as sodium sulfate and sodium chloride, in small quantities as impurities of the raw materials used. Thebalance to 100% by weight consists essentially of water.
