Definitions
- the present invention relates to an aqueous cleaning agent which contains nonionic surfactants and is suitable for cleaning in the sanitary field.
- the pH of acidic cleaning agents is usually between 0 and 2. Such a low pH makes special demands on the stability of the components.
- the thickeners used to increase the viscosity e.g. Amines or amine dehvates often supply products that are not stable in viscosity for a sufficient period of time.
- the viscosity of the products can vary greatly as a function of the storage temperature.
- Other typical thickeners such as guar flour, xanthan gum or cellulose derivatives are not stable in acidic media and quickly lose their thickening properties. Another disadvantage of these compounds is that they make no contribution to the cleaning performance of the cleaning agents.
- the thickeners used in neutral and alkaline detergents mean that the detergents dissolve only with difficulty in water in the event of a dilution process which may be provided. In addition to the aforementioned thickeners, this disadvantage can also be observed with synthetic polymers.
- nonionic surfactants especially tertiary amines, used as thickeners in sanitary cleaners.
- their storage stability is not sufficient.
- DE-OS 35 42 970 describes a sanitary cleaning agent which contains alkyl ether sulfates, amphoteric surfactants or mixtures of nonionic surfactants with oxyethylated amines as thickeners.
- alkyl ether sulfates containing alkyl ether sulfates, amphoteric surfactants or mixtures of nonionic surfactants with oxyethylated amines as thickeners.
- a sanitary cleaning agent which consists of 2 to 40 wt .-% acid, 2 to 10 wt .-% C ⁇ o-C 18 fatty alcohol ethoxylate with 8 to 14 EO units and 2 to 10 wt .-% thickener, in which a C ⁇ o -CC 8 fatty alcohol ethoxylate with 1 to 7 EO units is used and the free fatty alcohol content is below 5%.
- the examples in this document show that the viscosity decreases sharply when higher fatty alcohol contents are used. It is therefore necessary to use the starting products in high purity, which increases the costs of these products.
- the object of the present invention is to provide aqueous cleaning agents which do not have the disadvantages arising from the known products over a long storage period and which can be prepared from raw materials of conventional technical quality and purity.
- the present invention relates to aqueous cleaning agents which contain a surfactant mixture of nonionic surfactants from a) Ci 2 -C 22 alcohol alkoxylates with a degree of alkoxylation between 6 and 15, b) C 2 -C 22 alcohol alkoxylates with a degree of alkoxylation between 2 and 5 and c ) C ⁇ o-C 15 oxo alcohol alkoxylates with a degree of alkoxylation between 5 and 15, and
- the surfactant mixture of the non-ionic surfactants a, b, and c namely fatty alcohol alkoxylates with different degrees of alkoxylation and oxo alcohol alkoxylates, has a thickening effect in cleaning agents.
- Detergents can be obtained, the viscosity of which by dilution z. B. can be adjusted with water over a wide range customary in cleaning agents and which is stable over a long period of time even at the different pH values of these agents.
- the aqueous cleaning agents according to the invention preferably have a viscosity at 20 ° C.
- the viscosity can also be chosen higher up to a gel-like consistency.
- the C 2 -C 2 alcohol alkoxylates which are used as components a) and b) in the inventive composition are nonionic surfactants of the formula I.
- R 1 represents a saturated or unsaturated C 12 -C 22 alkyl group
- R 2 represents hydrogen and / or a methyl group and for component a) m for numbers from 6 to 15 and for component b) m for numbers of 2 to 5.
- the compounds can be obtained by alkoxylation of -C 2 -C 22 alcohols.
- Suitable C 2 -C 22 alcohols are, for example, the native fatty alcohols based on plants such as lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, behen alcohol, oleyl alcohol, elaidyl alcohol, ricinol alcohol, linoleyl alcohol, linolenyl alcohol and their technical mixtures, such as coconut oil alcohol - And palm kernel fatty alcohol or peanut fatty alcohol.
- mixed alkoxylates ie that m is greater than 1 and R 2 is hydrogen and methyl, up to 4 propylene oxide units, preferably 2 to 4 propylene oxide units, are generally present.
- C 2 -C 8 - fatty alcohol ethoxylates are particularly preferably used.
- C ⁇ o-C ⁇ 5 -oxoalcohol alkoxylates ie alkoxylates of branched C ⁇ 0 -C 15 -oxoalcohols, are also known compounds which can be obtained in a known manner by alkoxylation of oxo alcohols.
- the oxo alcohols used are compounds made from petrochemical raw materials, e.g. B. can be obtained by Roeln's oxosynthesis.
- C 3 -C 4 are particularly preferred as oxo alcohol alkoxylates. 5 -Oxo alcohol ethoxylates used.
- each of the three surfactants a, b and c can be present in an amount of 10 to 80% by weight, preferably 15 to 50% by weight, based on the surfactant mixture. lie.
- the content of this surfactant combination in the finished cleaner is preferably between 2 and 30% by weight, preferably between 5 and 20% by weight, based on the finished cleaning agent.
- the acidic cleaning agents preferred according to the invention contain acid as a further constituent. All non-corrosive acids are suitable. Citric acid, glycolic acid, acetic acid, formic acid, lactic acid, dicarboxylic acids such as e.g. Succinic acid, oxalic acid, adipic acid, phosphoric acid, amidosulfonic acid or mixtures of the acids mentioned.
- the acids are usually present in an amount between 2 and 40% by weight. The amount of acid used depends on the type of acid and the desired pH, which is preferably below 3 and in particular between 0 and 2.
- Cleaning agents according to the invention with an alkaline pH contain, in addition to the surfactants, alkaline salts, such as phosphates, in amounts of preferably up to 10% by weight, in particular 2 to 5% by weight, or free alkalis, such as NH 3 , alkanolamines, KOH or NaOH, in amounts preferably up to 8% by weight, in particular between 0.1 and 2% by weight. Mixtures of several alkalizing agents can of course also be present. The pH of these agents is preferably above 9, in particular between 10 and 14.
- the agent according to the invention may further contain anionic surfactants as cleaning-active constituents.
- Suitable anionic surfactants are, for example C 8 -C 18 fate -Alkylsul-, C 8 -C 8 alkyl ether sulfates, C 8 8 -C ⁇ alkanesulfonates, C 8 -C 18 - ⁇ -olefinsulfonates, sulfonated C 8 fatty acid -C ⁇ 8-C 1 -C 4 alkyl esters, C 6 -C 18 alkylbenzenesulfonates, sulfo ⁇ gemsteinsauremono- and -di-C 8 -C 12 alkyl esters, C 8 -C ⁇ 8 alkyl polyglycol ether carboxylates, C 8 -C 18 -N-acyltauhde , C 8 -C 18 -N-sarcosinates and C 8 -C 8 -alkyl isethionates
- the anionic surfactants can be present in amounts of up to 10% by weight, preferably 0.1 to 2.0% by weight, based on the total agent.
- the cleaning agent according to the invention can contain further active substances and auxiliaries customary in such agents, provided that they do not impair the properties of the agents according to the invention, for example dyes in an amount of up to 1% by weight, fragrances in an amount of to 2 wt .-% and corrosion inhibitors in an amount up to 5 wt .-%, each based on the Amount of finished detergent.
