Definitions
- Sodium is preferred as the cation, but it can also be replaced by lithium, potassium, ammonium or magnesium.
- aluminum silicates The compounds defined above which are capable of binding calcium are referred to below for the sake of simplicity as "aluminum silicates". This also applies in particular to the sodium aluminum silicates to be used with preference; all statements made for their use according to the invention and all statements regarding their production and properties apply accordingly to all of the compounds defined above.
- the aluminum silicates which are particularly suitable for use in washing and cleaning agents have a calcium binding capacity of preferably 50 to 200 mg CaO / g of the anhydrous aluminum silicate. If reference is made to anhydrous aluminum silicate in the following, this means the state of the aluminum silicate which is reached after drying at 800 ° C. for one hour. During this drying, the adhering and bound water is practically completely removed.
- the aluminum silicates are supplied or used, for example, as an aqueous suspension.
- suspension properties e.g. B. suspension stability and pumpability - the aluminum silicates dispersed in the aqueous phase still desirable.
- iso-tridecyl alcohol ethoxylates are branched-chain alcohols with a degree of branching of at least 50%; an unmanageable mixture of isomers, often with all possible branches such as methyl, ethyl, propyl, iso-propyl and the like. a.
- component A can be crystalline.
- y can be a number from 1.3 to 4.
- crystalline component A can be a type A zeolite.
- foam-suppressing additives or so-called solubilizers d. i.e. compounds which improve the solubility of the added dispersants in the aqueous phase.
- foam-suppressing substances for example foam-suppressing soap, silicone defoamers, foam-suppressing triazine derivatives, all of which are known and familiar to the person skilled in the art, can be used as foam suppressors.
- foam suppressors can be used as foam suppressors.
- solubilizing substances it is also generally not necessary to add solubilizing substances, but this may be indicated if the suspension according to the invention contains a hydrophilic, but sparingly water-soluble colloid, such as polyvinyl alcohol, as a stabilizing agent.
- Z is advantageous.
- a solubilizer - very suitable - is sodium toluenesulfonate - used.
- Component A can be amorphous or crystalline products, although it is of course also possible to use mixtures of amorphous and crystalline products and also partially crystalline products.
- the aluminum silicates can be naturally occurring or else synthetically produced products, with the synthetically produced products being preferred.
- the production can e.g. B. by reaction of water-soluble silicates with water-soluble aluminates in the presence of water.
- aqueous solutions of the starting materials can be mixed with one another or a component present in the solid state can be reacted with the other component present as an aqueous solution.
- the desired aluminum silicates are also obtained by mixing the two components present in the solid state in the presence of water.
- Aluminum silicates can also be prepared from Al (OH) 3, Al2O3 or SiO2 by reaction with alkali silicate or aluminate solutions. The production can also be carried out by other known processes. In particular, the invention relates to aluminum silicates which have a three-dimensional space lattice structure.
- the preferred calcium binding capacity which is approximately in the range from 100 to 200 mg CaO / g AS mostly around 100 to 180 mg CaO / g AS, is found above all in compounds of the composition: 0.7 - 1.1 Na2O ⁇ Al2O3 ⁇ 1.3 - 3.3 SiO2
- Such high drying temperatures are generally not recommended; Expediently, the temperature does not exceed 200 ° C. if the aluminum silicate is intended for use in detergents and cleaning agents.
- the aluminum silicates do not need to be dried at all after their preparation in order to prepare a suspension according to the invention; rather - and this is particularly advantageous - an aluminum silicate that is still moist from manufacture can be used.
- dried aluminum silicates at medium temperatures, for example at 80 to 200 ° C., until the adhering liquid water has been removed, in order to prepare suspensions according to the invention.
- These aluminum silicates preferably no longer contain primary or secondary particles with diameters above 45 ⁇ .
- Secondary particles are particles that are formed by aggregating the primary particles into larger structures.
- Such zeolite powder can according to DE-AS 24 47 021, DE-AS 25 17 218, DE-OS 26 52 419, DE-OS 26 51 420, DE-OS 26 51 436, DE-OS 26 51 437, DE-OS 26 51 445, DE-OS 26 51 485 are produced. They then have the particle distribution curves given there.

- the concentration of component A can preferably be 44 to 55% by weight, in particular 46 to 52% by weight or more.
- the concentration of components B and C in the aqueous suspension can preferably be from 1 to 2% by weight, in particular 1.4 to 1.6% by weight.
- This concentration is sufficient to stabilize a suspension with a solids content of 50% by weight or more.
- the suspension according to the invention has the advantage that it is sedimentation-stable in the temperature range below 25 ° C. and has a pumpable consistency.
- Another advantage is that the oxo alcohol ethoxylate is liquid at room temperature and therefore does not need to be heated.
- the aqueous suspensions can contain, in addition to the components A and B mentioned and, if appropriate, starting materials for the preparation of these components in comparatively small amounts. If the suspension is to be further processed into detergents and cleaning agents, the additional substances present are of course expediently substances which are suitable as constituents of detergents and cleaning agents.
- the suspensions according to the invention are distinguished by high stability and by further advantages.
- suspensions according to the invention are already as such, i.e. H. usable without further processing with or without further washing, bleaching and / or cleaning additives, for example as water softening agents, washing or cleaning agents and in particular as mild liquid abrasives with increased suspension stability.
- a particularly important use of the suspension is further processing to give dry-appearing, free-flowing or free-flowing detergents and cleaning agents which contain further compounds in addition to the suspension components.
- the suspensions according to the invention are particularly suitable for the production of powder detergents.
- an aqueous, flowable premix of the individual constituents of the agents is used and converted into a pourable product in the usual way.
- the aluminum silicates defined above are used in the form of the suspension according to the invention.
- the suspensions according to the invention can be processed into solid, pourable detergents and cleaning agents by any known method.
- one proceeds in the production of powdery, free-flowing detergents and cleaning agents that one Suspension according to the invention - for example from a storage container - is mixed with at least one washing, bleaching or cleaning component of the agent to be produced and the mixture is then converted into the powdery product by any process.
- a complexing agent is advantageously added, ie a compound which is able to complexly bind the alkaline earth metal ions responsible for the water hardness, in particular magnesium and calcium ions.
- the suspension according to the invention is preferably combined with at least one water-soluble surfactant which does not belong to the possible components of component B.
- suspensions according to the invention can be combined with substances capable of binding water of crystallization, expediently by spraying the suspension onto the compounds which are capable of binding water of crystallization, which are placed in a mixer, so that an ultimately solid, dry-appearing product is obtained with constant mixing.
- the suspensions according to the invention are subjected to the atomization drying with at least one further washing or cleaning compound.
- the products obtained by spray drying have a high calcium binding capacity and are easily wettable.
- Detergents which have been produced using the suspension according to the invention can be composed in various ways. In general, they contain at least one water-soluble surfactant which does not belong to the dispersants used according to the invention and which are present in the claimed aluminum silicate suspensions. In general, in addition to at least one further compound which has a washing, bleaching or cleaning action and is inorganic or organic, they contain, as calcium-binding compound, an aluminum silicate as defined above. In addition, other customary auxiliaries and additives, which are usually present in smaller amounts, can be present in such agents.
- a zeolite A filter cake and stabilizer are stirred, if appropriate with the addition of water.
- Components B and C are used as stabilizers.
- the degree of ethoxylation EO is given.
- the zeolite A filter cake used is produced according to DE-OS 26 51 485 and has the particle spectrum specified there.
- the surfactants contain polyethylene glycol (PEG) in amounts of 1%.
- PEG polyethylene glycol
- PEG with an average molecular weight of 800 is added to the 1: 1 mixture of the two individual surfactants in such amounts that the total content of PEG is 7%, 15% and 20% by weight. lies.
- the stability test is carried out after 3 days (Table 2), while the viscosity test and leak test are carried out on the same day (Tables 3 and 4).
