Abstract
A method of manufacturing a plurality of built, particulate detergent compositions comprises spray-drying a base powder and preparing a plurality of different, separate compositions by adding other constituents to quantities of the said base powder, preferably in proportions such that the base powder constitutes at least 15 wt% of each of the final compositions.
Description
DETERGENT COMPOSITIONS
This invention relates to the manufacture of granular detergent compositions for laundering fabrics.
Various methods are known for the preparation of a detergent composition. Customarily at least part of the composition is spray-dried while other materials are then added to the product of the spray-drying process. Such post-addition is customary for materials which are sensitive to heat and cannot be subjected to the spray-drying process. Other methods for the preparation of detergent compositions are known, for example granulation of ingredients and dry mixing of solid powders of similar bulk density.
A commercial detergent formulation is a complex mixture of ingredients designed to fulfil technical and market requirements for the particular product. A manufacturer may typically produce a variety of detergent formulations to be sold under different brand names into different market sectors. Each detergent formulation will be individually designed. Even if the same process plant is employed for production it will be normal practice for the manufacture of each composition to be carried out separately from the manufacture of others. The manufacturing plant will be stopped, and if necessary cleaned, in between the production of individual formulations. The complexity of a commercial detergent product militates strongly in favour of this practice of manufacturing each formulation separately from the manufacture of other products.
Surprisingly, we have now found that it is both possible and economically attractive to depart from this traditional practice and manufacture a plurality of detergent compositions with a spray-dried component which is common to more than one composition.
Thus, in one aspect, the present invention provides a method of manufacturing a plurality of built, particulate detergent compositions which method comprises spray-drying a base powder containing a mixture of materials and preparing a plurality of different, separate compositions by adding other constituents to separate quantities of the base powder. The number of different compositions made from the base powder may be two, three, four or even more.
Although it is envisaged that the base powder will be produced by spray drying, it is possible that even this base powder could be produced by a route which does not entail spray drying, e.g. granulation. Therefore in a second aspect this invention provides a method of manufacturing a plurality of built, particulate detergent compositions which method comprises preparing a base powder from a mixture of constituents, and preparing a plurality of different, separate compositions by adding other constituents to separate quantities of the base powder, in proportions such that the base powder provides at least 15% by weight of each of the said separate compositions.
The compositions produced in accordance with this invention may have some ingredients which are not present in all of the compositions. However it would generally be the case that a number of ingredients are present in all of the compositions but in proportions which are different between the various compositions.
In order to make a variety of different compositions using the same base powder, it will possibly be the case that for at least one of the compositions an ingredient will be introduced both in the base powder and by adding an additional quantity of the same ingredient to the base powder in order to provide the desired amount of this ingredient in the final composition. Typically, the plurality of compositions produced from a single base powder in accordance with this invention will have a number of ingredients which are post-dosed to the base powder in each of the compositions as well as possibly some ingredients which are present in only one or some of the plurality of compositions.
The compositions of this invention will generally contain detergent active, detergency builder and filler.
Normally they will also contain soluble silicate and an anti-redeposition agent such as sodium carboxymethyl cellulose. Some if not all of the compositions may include a bleaching agent and a bleach activator. Some if not all of the compositions will normally include enzyme(s), antifoam agent, fluorescent agent and perfume. In particular, the base powder may be devoid of fluorescent agent, and this may be added to some but not all of the compositions.
In this invention the base powder will contain a mixture of constituents, e.g. be a spray-dried mixture of materials. It will normally contain at least some inorganic detergency builder and it may contain some detergent actiye, although it is also possible to use a base powder which contains little or no organic material and then include substantially all the detergent active amongst the materials which are added to the base powder.
The detergent active used in the present invention may be selected from the classes of detergent active conventionally used for detergent compositions, especially non-soap anionic detergent actives and nonionic detergent actives. Some soap may be used. Typical amounts of such detergent actives are from 2 to 30% by weight of anionic detergent active or soap or mixtures thereof when these are used alone, from 2 to 20% by weight of nonionic detergent active when used alone and, when a binary mixture of anionic and nonionic actives is used, from 2 to 25% by weight of anionic active and from 0.5 to 20% by weight of nonionic active. Such binary mixtures can be either anionic rich or nonionic rich.When a so-called ternary mixture of anionic, nonionic and soap is used, preferred amounts of the individual components of the mixture are from 2 to 15% by weight of anionic detergent active, from 0.5 to 7.5% by weight of nonionic active, and from 1 to 15% by weight of soap.
Examples of anionic detergent actives which can be used are alkyl benzene sulphonates, particularly sodium alkyl benzene sulphonates having an average alkyl chain length of C12; primary and secondary alcohol sulphates, particularly sodium C12-C15 primary alcohol sulphates, olefin sulphonates, primary and secondary alkane sulphonates and alkyl ether sulphates.
The soaps which can be used are preferably sodium soaps derived from naturally-occurring fatty acids. In general these soaps will contain from about 12 to about 20 carbon atoms and may be saturated or partly unsaturated.
Three groups of soaps are especially preferred: those derived from coconut oil and palm kernel oil, which are saturated and predominantly in the C12 to C14 range, those derived from tallow which are saturated and predominantly in the C14 to C1 8 range, and soaps containing sodium linoleate, sodium linolenate and sodium oleate. Oils which are rich in the unsaturated substances (as glycerides) include groundnut oil, soyabean oil, sunflower oil, rapeseed oil and cottonseed oil. Of course, all of these groups of soaps may be used in admixture with each other, with other soaps not included amongst the groups enumerated, and with nonsoap detergent-active material.
The nonionic detergent actives which can be used include the primary and secondary alcohol ethoxylates, especially the C12-C15 primary and secondary alcohols ethoxylated with from 2 to 20 moles of ethylene oxide per mole of alcohol. Amine oxides and zwitterionic compounds such as betaines and sulphobetaines can also be used as detergent active materials.
If nonionic detergent active is included in the compositions of this invention it may be included in the form of an adjunct, that is to say the nonionic detergent active is sprayed onto a suitable absorbent carrier material to form a solid particulate material. This solid particulate material is then added as one of the materials added to the base powder. The addition of nonionic detergent active absorbed onto a carrier material is disclosed in our published European patent application 221776.
The detergency builder materials used in this invention may be builder materials conventionally used in detergent compositions. Soluble phosphate builders may be employed in which case it will generally be convenient to include at least some sodium tripolyphosphate in the spraydried base powder.
Examples of phosphorus-containing inorganic watersoluble detergency builder salts, include the alkali metal pyrophosphates, orthophosphates, polyphosphates and phosphonates. Specific examples of inorganic phosphate builders include sodium and potassium tripolyphosphates, orthophosphates and hexametaphosphates.
Insoluble aluminosilicate builders may be used in this invention. These also can be included in the spraydried base powder.
It is also possible for this invention to employ other builder materials such as alkalimetal bicarbonate or carbonate (the latter possibly accompanied by high surface area calcite) or organic builder materials.
Examples of water-soluble organic detergency builder salts include the alkali metal, ammonium and substituted ammonium polyacetates, carboxylates, polycarboxylates, polyacetyl carboxylates and polyhydroxysulphonates.
A plurality of compositions made from a single base powder, according to this invention, may all have, by weight of the whole composition
2-30% detergent active 5-60t detergency builder 2-40t filler (e.g. sodium sulphate)
The amounts of other constituents, if present, will typically lie in the following ranges, which are percentages by weight of the whole composition.
Soluble silicate 2-10 Antiredeposition agent 0.1-3 %
Bleach 2-20%
Bleach activator 1-10t Enzyme(s) 0.1-3 t Fluorescer 0.01-31%
Non-soap anti-foam agent(s) 0.1-5 t Clay 1-20%
Perfume 0.1-3 %
Manufacture of the base powder required for this invention may be carried out by entirely conventional spraydrying techniques or alternatively by other conventional techniques such as granulation. If a spray-dried base powder contains silicate this may be introduced into the base powder by spraying a silicate solution into the spraydrying tower separately from the slurry which is being spray-dried. Such a process is disclosed in our published
European application 260971.The materials which are subsequently added to the base powder may be added by any convenient procedure, such as simple dry mixing.
Embodiments of this invention will now be described in the following examples in which all parts and percentages are by weight unless otherwise stated.
Example 1
The appropriate mixture of ingredients was made into a slurry and spray-dried to give a base powder of the following composition:

An adjunct containing nonionic detergent active was prepared by spraying nonionic detergent active onto a carrier which was habit modified Burkeite as described in our published European application 221776. The ratio of nonionic detergent active to carrier was 4:13.
Granules incorporating the bleach activator,
N,N,N1,N1 tetraacetyl ethylene diamine (TAED) in finely divided form having an average particle size less than 150um, were obtained by granulating this activator with a suitable carrier material, such as sodium tripolyphosphate and/or potassium tripolyphosphate to give granules having an average particle size of from 100 to 2000cm, preferably 250 to 1000us. Other granulation methods, for example using organic and/or inorganic granulation aids, could be used if desired.
The base powder, the anti-foam granules, the bleach activator granules and the nonionic-containing adjunct were combined together with other materials in varying proportions to give four fully formulated products as shown in Table 1, below.

All four of the compositions have added anti-foam granules, nonionic detergent active and perfume. Three of them also have added sodium sulphate, bleach and enzymes. In order to provide the desired quantity of tripolyphosphate in the second and third of these compositions additional tripolyphosphate is added to the base powder even though some tripolyphosphate is already present in the base powder.
All four of the compositions produced in this example are fully formulated compositions suitable for packaging and sale.
Example 2
A slurry of ingredients is spray-dried to produce a base powder of the following composition:
Parts by Weight
Alkyl benzene sulphonate 9.0
Zeolite 24.0
Sodium carboxymethyl cellulose (SCMC) 0.6
Ethylenediaminetetraacetic acid (EDTA) 0.2
Fluorescer 0.2

Water 7.0 45.0
To spray-dry this composition the silicate is sprayed into the spray-drying tower below the inlets for slurry in the manner described in our published European application 260971. Anti-foam granules, nonionic detergent active-containing adjunct and other ingredients are added to the base powder to produce four fully formulated compositions ready for packaging and sale as set out in
Table 2 below.It will be seen that all four compositions contain varying amounts of the anti-foam granule and the nonionic active-containing adjunct while three of the compositions also include, amongst the ingredients added to the base powder, bleach, enzymes, sodium carbonate and sodium sulphate.

All of the detergent active is added after spray-drying. For these compositions the anionic detergent active, namely alkyl benzene sulphonate, is itself formulated into an adjunct in which the anionic detergent active is supported on a solid carrier.
Application of anionic surfactant to various inorganic carriers is described in UK 918499.
Producing four compositions from a single base powder as described in any of Examples 1, 2 and 3 requires more capital equipment than producing the same four compositions by the traditional route of spray-drying a base powder tailored to each composition and adding to this only such constituents as cannot be spray-dried. However, savings are made by operating the spray-drying tower to produce a single base powder rather than four different base powders. Notably there is a saving in the quantity and value of raw materials which must be stock piled in order to ensure continuous supply of raw materials for the spraydrying tower. There is also less stock piling of base powders produced from the spray-drying tower since only a single base powder is being produced and can be used as required for the production of the four different finished products. Further savings in operating costs arise from the fact that addition of materials to a base powder reduces the proportion of the final product which is subjected to the energy-consuming spray-drying step. Calculations show that an overall saving is achievable even in spite of the greater requirement for fixed plant.
