- a granular water-softening composition comprising 50-60 wt% fine- crystalline zeolite, 4-12 wt% sodium carbonate, 4-15 wt% sodium citrate, 3-5 wt% acrylic or acrylic/maleic polymer (sodium salt), optionally up to 2 wt% sodium carboxymethyl cellulose, and 12-25 wt% water. It can be used as an additive to supplement the performance of a commercially available detergent powder.
- composition exemplified contains 62.5 wt% (sic) zeolite A, 5.1 wt% sodium carbonate, 10.5 wt% sodium citrate, 4.2 wt% acrylic/maleic copolymer, 0.3 wt% carboxymethylcellulose, and 17.5 wt% water.

- a homogeneous granular detergency builder composition comprising an ion-exchanging zeolite, sodium carbonate, and another inorganic salt, for example, sodium sulphate, sodium bicarbonate or a sodium phosphate.
- the present invention provides a detergency builder additive, for use in the washing of soiled laundry, in conjunction with a main wash detergent powder comprising one or more organic surfactants and one or more detergency builders, the builder additive being substantially free of organic surfactants and comprising:
- the present invention also provides a detergent system of the Baukasten (building block) type for washing soiled laundry, comprising as separate components:
- the present invention further provides a method for washing soiled laundry in a domestic washing machine, using a detergent system as defined in the previous paragraph, which method includes the steps of separately introducing a main wash powder as defined in paragraph (a) above, a detergency builder additive as defined in paragraph (b) above, and optionally a bleach additive (c), into the washing machine.
- the invention in its first aspect relates to a detergency builder additive comprising three essential components: alkali metal aluminosilicate, organic sequestrant builder, and sodium carbonate.
- detergency builder performance of aluminosilicates is deficient in some respects and needs to be supplemented by the incorporation of other builders, of which the organic sequestrants have proved especially effective.
- the detergency builder additive of the invention differs from that disclosed in the above-mentioned EP 243 908A (Henkel) in having a significantly lower proportion of organic sequestrant builder, yet surprisingly its performance as a builder additive is at least as good.
- the lower level of organic material is environmentally beneficial because the oxygen demand during degradation is lower.
- the detergency builder additive described in EP 243 908A also contains two different organic sequestrants, an acrylate/maleate copolymer (3-5 wt%, for example, 4.2 wt%) and a citrate (4-15 wt%, for example, 10.5 wt%), while the content of sodium carbonate is only 4-12 wt% (for example, 5.1 wt%).
- the total level of organic sequestrant builder in the exemplified composition is therefore 14.7 wt%, and the total level of inorganic builder 67.6 wt%.
- especially preferred detergency builder additives in accordance with the invention contain a citrate as the sole organic sequestrant builder.
- the alkali metal (preferably sodium) aluminosilicates used in the detergency builder additive of the invention may be either crystalline or amorphous or mixtures thereof, and they have the general formula: 0.8-1.5 Na20. AizOa. 0.8-6 Si0 2 .
- the preferred sodium aluminosilicates contain 1.5-3.5 Si0 2 units (in the formula above). Both the amorphous and the crystalline materials can be prepared readily by reaction between sodium silicate and sodium aluminate, as amply described in the literature.
- Suitable crystalline sodium aluminosilicate ion-exchange detergency builders are described, for example, in GB 1 473 201 (Henkel) and GB 1 429 143 (Procter & Gamble).
- the preferred sodium aluminosilicates of this type are the well-known commercially available zeolites A and X, and mixtures thereof. Especially preferred is zeolite 4A.
- novel zeolite P described and claimed in our copending British Patent Applications Nos. 88 25783.7 filed 3 November 1988 and 89 10029.1 filed 2 May 1989 may also be used in the detergency builder additive of the invention.
- the builder additive of the invention contains at least 50 wt%, preferably from 50 to 65 wt%, more preferably from 55 to 65 wt%, of aluminosilicate.
- An important characteristic of the builder additive of the invention is the relatively high content of sodium carbonate: 15 to 20 wt%.
- builder additive of the invention in conjunction with a separate main wash powder enables builder level to be tailored to suit conditions of water hardness so that optimum alkalinity and wash performance are obtained.
- the total amount of aluminosilicate and sodium carbonate in the builder additive of the invention is preferably at least 70 wt%, and more preferably at least 75 wt%.
- the organic sequestrant builder is present in an amount of from 2 to 12 wt%. If more than one organic sequestrant builder is present, the total amount should lie within this range. Preferably the amount of organic sequestrant builder present is from 2 to 10 wt%, more preferably from 2 to 7 wt%, and most preferably from 4 to 7 wt%.
- the organic sequestrant builder is preferably a polycarboxylate material.
- Polycarboxylate detergency builders are well. known to the skilled detergent formulator, and include polymeric polycarboxylates such as polyacrylates, acrylic/maleic copolymers and polyacetal carboxylates, and monomeric polycarboxylates such as nitrilotriacetates, citrates, oxydisuccinates, tartrate monosuccinates and disuccinates, and carbox- ymethyloxysuccinates; this list is not intended to be exhaustive. A mixture of two or more organic sequestrant builders may if desired be present.
- the organic sequestrant builder comprises a water-soluble salt of citric acid, for example, an alkali metal citrate or ammonium citrate, conveniently sodium citrate.
- citric acid for example, an alkali metal citrate or ammonium citrate, conveniently sodium citrate.
- Citrates have the known advantage of being readily biodegradable and environmentally innocuous.
- the builder additive contains a water-soluble citric acid salt as the sole organic sequestrant builder.
- polycarboxylate builders suitable for use in the detergency builder additive of the invention comprises the water-soluble salts of polymeric polycarboxylic acids.
- water-soluble salts of homo- and copolymers of acrylic acid, and more especially acrylic/maleic copolymers are conveniently and preferably used in sodium salt form.
- the detergency builder additive of the invention may also, if desired, contain both polymer and citrate, provided that the total amount of the two is within the range of 2 to 12 wt%; but the use of a single organic sequestrant, especially citrate, is generally preferred for good performance combined with simplicity and ease of formulation.
- Polymeric polycarboxylate builders which may suitably be used, alone or in combination, in the detergency builder additive of the invention include the following:
- the ratio of aluminosilicate to organic sequestrant builder is preferably within the range of from 5:1 to 30:1, more preferably from 10:1 to 15:1.
- the builder additive is suitably prepared by processes involving dry-mixing of the sodium carbonate with the remaining ingredients.
- the alkali metal aluminosilicate is conveniently incorporated in the form of a granular spray-dried material, for example, as described in EP 191 187B, EP 195 127A, EP 279 038A, EP 279 039A and EP 279 040A (Degussa).
- organic sequestrant builder is available in granular form, that may conveniently be dry-mixed with the granular aluminosilicate and the sodium carbonate. Both sodium citrate and acrylic/maleic copolymer may conveniently be incorporated by this method.
- An alternative procedure involves spraying an aqueous solution of the organic sequestrant builder onto the granular aluminosilicate, and then dry-mixing the resulting granules with the sodium carbonate.
- the detergency builder additive of the invention may if desired contain minor amounts of other ingredients, for example, processing aids, binders, inorganic salts, perfumes or colourants. Some of these minor ingredients may be imported directly from granular aluminosilicate raw material.
- the detergency builder additive is substantially free of organic surfactants. That does not preclude the presence of low levels, for example, up to 5 wt% and preferably not more than 3 wt%, of surfactant material, for example, imported from commercially available aluminosilicate granules, as a binder or processing aid.
- the invention is concerned with a wash system of the Baukasten (building block) type which provides in separate packs a main wash powder, adequate in itself for lightly soiled loads and low water hardness, and a builder additive that can be used to supplement the main wash powder when the load is heavily soiled or the water hardness high.
- the Baukasten system has the environmental benefit of reducing the unnecessary usage of chemicals.
- the main wash powder is thus sufficiently fully formulated to enable it to be used alone under favourable wash conditions. It contains at least one organic surfactant, and at least one detergency builder.
- the total amount of detergent-active material (surfactant) in the main wash powder is suitably from 2 to 50% by weight, and is preferably from 5 to 40% by weight.
- the main wash powder may contain one or more soap or non-soap anionic, nonionic, cationic, amphoteric or zwitterionic surfactants, or combinations of these.
- soap or non-soap anionic, nonionic, cationic, amphoteric or zwitterionic surfactants or combinations of these.
- suitable detergent-active compounds are available and are fully described in the literature, for example, in "Surface-Active Agents and Detergents", Volumes I and II, by Schwartz, Perry and Berch.
- the preferred detergent-active compounds that can be used are soaps and synthetic non-soap anionic surfactants and nonionic surfactants.
- Synthetic anionic surfactants are well known to those skilled in the art. Examples include alkylbenzene sulphonates, particularly sodium linear alkylbenzene sulphonates having an alkyl chain length of C 8 -C, 5 ; primary and secondary alkyl sulphates, particularly sodium C 12 -C 15 primary alcohol sulphates; olefin sulphonates; alkane sulphonates; dialkyl sulphosuccinates; and fatty acid ester sulphonates.
- alkylbenzene sulphonates particularly sodium linear alkylbenzene sulphonates having an alkyl chain length of C 8 -C, 5
- primary and secondary alkyl sulphates particularly sodium C 12 -C 15 primary alcohol sulphates
- olefin sulphonates alkane sulphonates
- dialkyl sulphosuccinates and fatty acid ester sulphonates.
- Suitable nonionic detergent compounds which may be used include in particular the reaction products of compounds having a hydrophobic group and a reactive hydrogen atom, for example, aliphatic alcohols, acids, amides or alkyl phenols with alkylene oxides, especially ethylene oxide either alone or with propylene oxide.
- Specific nonionic detergent compounds are alkyl (C6 -22) phenol-ethylene oxide condensates, the condensation products of linear or branched aliphatic C 8 - 20 primary or secondary alcohols with ethylene oxide, and products made by condensation of ethylene oxide with the reaction products of propylene oxide and ethylenediamine.
- Other so-called nonionic detergent compounds include long-chain tertiary amine oxides, tertiary phosphine oxides, and dialkyl sulphoxides.
- the primary and secondary alcohol ethoxylates especially the C12 -15 primary and secondary alcohols ethoxylated with an average of from 5 to 20 moles of ethylene oxide per mole of alcohol.
- soaps of fatty acids are preferably sodium soaps derived from naturally occurring fatty acids, for example, the fatty acids from coconut oil, beef tallow, sunflower or hardened rape seed oil.
- Detergent compositions suitable for use in automatic fabric washing machines generally contain anionic surfactant, or nonionic surfactant, or both together in any proportions, and soap may also be present if desired.
- the main wash powder also contains one or more detergency builders. Since it is intended that the performance of the main wash powder in hard or even moderately hard water should be boosted by the additional use of the detergency builder additive, the level of builder in the main wash powder may be relatively modest.
- Detergency builders are well-known in the art.
- Inorganic builders that may be present include alkali metal (generally sodium) ortho-, pyro- and tripolyphosphate, the latter material being especially effective.
- the main wash powder contains less than 10 wt% of inorganic phosphate, and is more preferably substantially free of inorganic phosphate.
- Non-phosphate detergency builders are also well known to the skilled detergent formulator.
- Inorganic non-phosphate builders include alkali metal (generally sodium) carbonates and aluminosilicates; and examples of organic non-phosphate builders have been listed above in the description of the builder additive of the invention.
- the main wash powder comprises a builder system based on an alkali metal aluminosilicate and/or an alkali metal carbonate.
- a carbonate-based builder system suitable for use in the main wash powder is an alkali metal carbonate in combination with finely divided calcite as described and claimed in GB 1 437 950 (Unilever).
- the main wash powder contains a builder system similar to that of the builder additive, comprising an alkali metal aluminosilicate, optionally an alkali metal carbonate, and an organic sequestrant builder.
- the preferred organic sequestrant builders for use in the main wash powder are those mentioned above as preferred for use in the builder additive; the organic sequestrant builders used in the two components may be the same or different.
- the preferred ratio of aluminosilicate to organic sequestrant builder in the main wash powder is within the range of from 5:1 to 30:1.
- the main wash powder may contain other functional ingredients commonly encountered in detergent powders, for example, peroxy bleaches, bleach activators, bleach stabilisers, enzymes, fabric softeners, antifoams, antiredeposition agents, sodium silicate, perfumes and other materials well known to the skilled detergent formulator.
- Bleaching ingredients are preferably separated out into a second additive, as described in more detail below, which need only be used when the soiling of the washload necessitates it.
- the main wash powder is preferably free or substantially free of inert fillers, for example, inorganic salts such as sodium sulphate, that do not contribute to wash performance.
- inert fillers for example, inorganic salts such as sodium sulphate
- Small amounts of apparently inert ingredients, for example, inorganic salts may however be present in order to ensure that powder properties such as flow and resistance to caking are acceptable.
- the bleach additive is the bleach additive
- the bleach additive which optionally, and preferably, forms part of the Baukasten detergent system of the invention, suitably comprises a persalt or peracid, if necessary or desired together with a bleach precursor and/or a bleach stabiliser.
- the bleach additive may, for example, comprise a major proportion of an inorganic persalt, for example, sodium perborate monohydrate or tetrahydrate; a lesser proportion of a bleach precursor, for example, tetracetylethylene diamine; and any suitable minor ingredients, for example, bleach stabiliser, colourant, perfume.
- an inorganic persalt for example, sodium perborate monohydrate or tetrahydrate
- a bleach precursor for example, tetracetylethylene diamine
- any suitable minor ingredients for example, bleach stabiliser, colourant, perfume.
- the invention provides a method for washing soiled laundry in a domestic washing machine, which utilises the flexibility of the Baukasten detergent system defined above.
- the main wash powder alone may be employed. If the load is stained, the main wash powder is suitably used in conjunction with the bleach additive. In hard water conditions, the main wash powder and builder additive should both normally be used, if necessary in conjunction with the bleach additive. Different amounts of the main wash powder, the bleach and builder additives will generally be appropriate for different circumstances.
- the main wash powder, the builder additive and (if present) the bleach additive will generally be packed in separate containers within a larger outer container, and instructions will be provided to enable the consumer to use amounts and proportions of the components most suited to the wash conditions on any particular occasion.
- the main wash powder, the builder additive and (if appropriate) the bleach additive should also be available separately as refills, since supplies of the three components are unlikely to be exhausted simultaneously.
- instructions will be provided indicating recommended dosages of the various components under different conditions of water hardness, wash load size, degree of soiling of the washload, washing machine programme and other relevant parameters.
- the recommended amounts and proportions will of course depend on the exact formulations of those components.
- the various components of the Baukasten system of the present invention may be colour-coded to aid the consumer, that is to say, the main wash powder, the builder additive and (if present) the bleach additive may be of different colours.
- the main wash powder which is the component used in the larger (or largest) amount, is uncoloured (ie of natural colour) in order to minimise the usage of colourant, while the builder additive and (if present) the bleach additive are deliberately given a distinctive appearance by the use of colourant.
- the powders may be homogeneously coloured, or, preferably, may contain a small percentage - about 0.5 to 3 wt%, preferably 1 to 2 wt% - of coloured speckles, the bulk remaining of natural colour, thus achieving distinctiveness with a minimum usage of colourant.
- the additives may contain differently coloured speckles, for example, green for the builder additive and blue for the bleach additive.
- the speckles should preferably consist simply of coloured particles of the component itself, or of a functional ingredient that would in any case be present either in the component in question or in another component.
- a builder additive was prepared to the following formulation by dry-mixing:
- This builder additive contained 76.52 wt%, in total, of zeolite (anhydrous basis) and sodium carbonate; and 5.0 wt% of organic sequestrant builder (sodium citrate).
