Definitions
- the present invention relates to the cleaning and rinsing of textile fabrics, wherein both wash and rinse compositions are placed in a wash liquor with the fabric, and then a rinsing step is carried out in a rinse liquor, whereby release of at least some of the rinse composition is delayed until the rinse.
- US-A-4 801 636 discloses a comminuted wash additive in a water soluble polymeric film envelope or in microcapsules of the water soluble polymer, or in a water-insoluble envelope sealed with the water soluble polymer.
- the water soluble polymer typically comprises polyvinyl alcohol and alkyl cellulose monomer units together with a cross-linking agent. The polymer is insoluble at higher pH but becomes increasingly soluble as the pH is reduced.
- the coating comprises a water soluble polymer, preferably a polyvinyl alcohol or gelatin of defined molecular weight and isoelectric point.
- JP 60/141,705 discloses a specific copolymer which is insoluble in alkaline water of pH of 9.5 or higher and soluble in water of pH of 8.5 and lower. This is achieved by using a terpolymer, whereby the ratio of monomers are in a specific range to assure that de desired solubility properties are observed in solutions of 250 ppm linear alkyl benzenesulfonic acid (high pH) and 15 ppm ppm linear alkylbenzenesulfonic acid (low pH).
- a problem with the terpolymers as disclosed in this Japanese patent publication is that they are less suitable for use in combination with cleaning compositions comprising a mixture of surfactants in particular in combination with cleaning compositions comprising a combination of anionic and nonionic surfactants.
- the present invention provides a method of washing and rinsing a textile fabric, the method comprising:
- the level of A is from 20- 60 wt%
- the level of B is preferably from 5 - 40 wt% or 80 - 94 wt% based on the weight of the terpolymer.
- the polymers as described above can have a positive contribution to the cleaning performance of the composite detergent product.
- Composite washing products of the invention can take any suitable form.
- the cleaning composition can be a liquid, powder or unit dose form such as a sachet or tablet.
- the encapsulated rinse additive can take any suitable form e.g. sachet, capsule, coated particulates etc.
- the rinse additive can equally take any suitable form for example liquid, powder, tablet, plastic composition etc.
- the composite washing product may comprise the cleaning product and the rinse additive as separate entities, but more preferred the cleaning product and the rinse additive are combined in a single entity.
- suitable single entity composite washing products are for example powdered cleaning composition wherein encapsulated rinse additives are present as small particles mixed with the powder; a powdered cleaning composition in a sachet, wherein the sachet also comprises an encapsulated rinse additive for example as one or more particles or a capsule; a liquid cleaning composition contained in a capsule wherein the capsule also comprises a second rinse additive capsule in accordance to the invention.
- An especially preferred embodiment of the invention relates to a cleaning tablet with a first region comprising the cleaning composition and a second region comprising the encapsulated rinse additive. It will be apparent to the skilled person that other combinations of cleaning compositions and encapsulated rinse additives can be formed. For ease of reference the invention will be described in more detail with reference to a tablet comprising a first cleaning region and a second rinse additive region.
- Tablets can be made by several techniques e.g. extrusion, casting or compression. Tableting suitably may entail compaction of a particulate composition.
- a variety of tableting machinery is known, and can be used. Generally it will function by stamping a quantity of the particulate composition which is confined in a die. Tableting machinery able to carry out such operations is known.
- suitable tablet presses are available from Fette and from Korsch.
- the size of a tablet will suitably range from 10 to 160 grams (gm), preferably from 15 to 60 gm, depending on the conditions of intended use, and whether the tablet represents a dose for an average load in a fabric washing or a fractional part of such a dose.
- the tablets may be of any shape. However, for ease of packaging they are preferably blocks of substantially uniform cross-section, such as cylinders or cuboids.
- the overall density of a tablet is preferably 1040 or 1050 gm/litre, better 1100 gm/litre, up to 1300 or 1350 gm/litre or even more. The tablet density may well lie in a range up to no more than 1250 or even 1200 gm/litre.
- Tablets in which the rinse composition is held in a separate region for example a central cavity (the body of the tablet) containing a wash composition may be formed using an appropriately shaped die or by delivering the rinse additive to the tablet after initial shaping.
- the rinse additive for use in accordance to the invention contains at least one agent which exerts a beneficial action upon a textile in the rinse.
- Suitable examples of such agents include fabric softening agents, especially cationic softening compounds, antistatic agents, ease of ironing agents, anti-wrinkling/crease protection agents, perfume and optical brighteners.
- delayed release by means of the invention is also beneficial for e.g. oxygen bleach, bleach activators, soil release agent, enzymes, suds supressors, disinfectants, anti-redeposition aids, dye transfer inhibitors.
- the rinse additive material may be in combination with a suitable carrier material.
- Rinse additives may suitably contain one or more formulation aids and/or dispersing aids.
- the weight ratio of cleaning composition to encapsulated rinse additive is from 50 : 1 to 1 : 5, more preferred from 10 : 1 to 1 : 1.
- Suitable rinse additive agents are:
- Suitable cationic fabric softening compounds may be selected from those typically included in rinse-added fabric softening compositions, for example cationic softening agents, clay, cellulases softeners, polysiloxanes.
- the cationic softening agent is a water insoluble quaternary ammonium material which comprises a compound having two C 12-18 alkyl or alkenyl groups connected to the nitrogen head group via at least one ester link. It is more preferred if the quaternary ammonium material has two ester links.
- a first preferred type of ester-linked quaternary ammonium material is represented by formula (I): wherein T is each R 1 group is independently selected from C 1-4 , alkyl or hydroxyalkyl or C 2-4 alkenyl groups; and wherein each R 2 group is independently selected from C 8-28 alkyl or alkenyl groups;
- X- is any suitable anion including a halide, acetate or lower alkosulphate ion, such as chloride or methosulphate, n is 0 or an integer from 1 to 5, and m is an integer from 1 to 5.
- Preferred materials of this class such as 1,2 bis[hardened tallowoyloxy]-3- trimethylammonium propane chloride and their method of preparation are, for example, described in US 4 137 180 (Lever Brothers).
- these materials comprise small amounts of the corresponding monoester as described in US 4 137 180 for example 1-hardened tallowoyloxy - 2-hydroxy 3-trimethylammonium propane chloride.
- a second type of ester-linked quaternary ammonium material is represented by the formula (II): wherein T, R 1 , R 2 , n, and X - are as defined above.
- dialkenyl esters of triethanol ammonium methyl sulphate and N-N-di(tallowoyloxy ethyl) N,N-dimethyl ammonium chloride are particularly preferred.
- Tetranyl® AOT-1 (di-oleic ester of triethanol ammonium methyl sulphate 80% active), AO-1(di-oleic ester of triethanol ammonium methyl sulphate 90% active), AHT-1 (di-hardened oleic ester of triethanol ammonium methyl sulphate 90% active), L1/90 (partially hardened tallow ester of triethanol ammonium methyl sulphate 90% active), L5/90 (palm ester of triethanol ammonium methyl sulphate 90% active (supplied by Kao corporation) and Rewoquat WE15 (C 10 -C 20 and C 16 -C 18 unsaturated fatty acid reaction products with triethanolamine dimethyl sulphate quaternised 90 % active), ex Witco Corporation.
- a third preferred type of quaternary ammonium material is represented by formula (III): where R 1 and R 2 are C 8-28 alkyl or alkenyl groups; R 3 and R 4 are C 1-4 alkyl or C 2-4 alkenyl groups and X - is as defined above.
- Examples of compounds within this formula include di(tallow alkyl)dimethyl ammonium chloride, di(tallow alkyl) dimethyl ammonium methyl sulphate, dihexadecyl dimethyl ammonium chloride, di(hardened tallow alkyl) dimethyl ammonium chloride, dioctadecyl dimethyl ammonium chloride and di(coconut alkyl) dimethyl ammonium chloride.
- the quaternary ammonium material is biologically degradable.
- Co-active softening surfactants for cationic surfactants may also be incorporated in an amount from 0.01 to 20% by weight, more preferably 0.05 to 10%, based on the total weight of the rinse additive.
- Preferred co-active softening surfactants are fatty amines and fatty N-oxides.
- British Patent Specification GB 1 368 599 discloses the use of cellulolytic enzymes, i.e. cellulases, as harshness reducing agents. It is thought that cellulase achieves its anti-harshening effect on, e.g. cotton, by cleaving the cellulosic fibrils which form on the cotton fibres during the normal washing process.
- This cleavage prevents the fibrils from bonding together and thereby introducing a degree of rigidity into the fabric.
- cellulases which have an optimum activity at alkaline pH values, such as those described in British Patent Specifications GB 2 075 028 A (Novo Industries A/S), GB 2 095 275 A (Kao Soap Cc Ltd) and 2 094 826 A (Kao Soap Co ltd).

- Figure 1 shows a unit dose unit 1 for use according to the present invention. It comprises a tablet 3 of a granular detergent cleaning composition 5, having a composition in the range of formulation A (parts by weight):- Formulation A Parts by weight NaLAS 9.3 Nonionic 7EO 2.6 Nonionic 3EO 1.4 Soap 0.7 Zeolite A24 (anhydrous) 20.8 Sodium acetate 27.4 Soda ash 3.1 SCMC 0.4 Minors etc.
- the tablet is formed by compression of the granular ingredient 5 but in a die such as to be formed with a central cavity 7.
- the central cavity 7 is formed with Polymer 1 which is a polyacrylate-terpolymer, synthesized from a blend of the following weight composition 23% MMA (methylmethylacrylate), 45% DMAEMA (N,N-dimethylamino ethyl methacrylate) and 32% DMAPMA (dimethylaminopropylmethacrylic acid amine)
- a granular fabric softening composition 11 (Formation B) is, together with a dissolution aid like Na-acetate or Na-citrate, dispersed in the polymer composition 9 such that it becomes encapsulated therein.
- the fabric softener is mixed with the polymer and poured into the cavity 7, whereupon it sets to form a solid matrix of the composition 11 and solidified polymer 9.
- the granular fabric softening composition 11 has the following formulation B:- Formulation B Material Parts by weight HEQ 34.5 Urea 41.48 Dobanol 91/6 6.14 Water 5.77 Perfume 2.88 PEG 1.95 Dye 0.28 Microsil GP 7.00
- Polymer 1 is such that it is substantially insoluble at the pH and ionic strength of the wash liquor (the granular wash composition 5 dissolves quite rapidly, at least sufficiently to achieve these conditions). However, the Polymer 1 is readily soluble at the pH and ionic strength of the rinse liquor).
- Example 2 A variant of this example, wherein the polymer is in the form of a melt, is described hereinbelow in Example 2.

- the polymer used in to form the lining 75 and film 73 is identical to that of Polymer 1 recited above.
- the tablet of Figure 2 dissolves in the wash liquor but the pH of the wash liquor is such that the "capsule" formed by the polymer film 73 and lining 75 does not dissolve. It survives until the rinse cycle, when the lower pH allows it to dissolve and the contents released. At that point, the gel 69 dissolves or disperses, releasing the rinse composition 67 into the rinse liquor.
- the "capsule" of polymer is fragile. Therefore, it is especially advantageous in this embodiment for the tablet as a whole to be dosed by means of a net.
- Figure 3 shows a capsule 81 according to a fourth embodiment of the present invention.
- a granule of 1.5 cm diameter is formed by granulating the composition of Formula B (fabric softening composition) with a dissolution aid such as sodium citrate or sodium acetate in a fluid bed granulator, operated such that large agglomerates can form. This produces a nearly-spherical granule 83. This granule is then dipped-coated in a melt of Polymer 1 as recited above. In this way, the granule 83 is coated with a polymer film 85.
- a dissolution aid such as sodium citrate or sodium acetate
