Abstract
C.1012 Canada Brazil ABSTRACT OF THE DISCLOSURE
A detergent product comprises a particulate detergent composition contained within a closed water-insoluble bag which has a water-sensitive seal, whereby the contents of the bag are discharged on contact of the bag with water. Use of such detergent products improves detergent dosage control and hence cost-effectiveness, and is particularly beneficial for detergent compositions of higher density than customary or which contain water-insoluble ingredients.

Description
Z20g~
cC.1012 The invention relates to detergent products which are suitable for fabric washing purposes and which contain detergent compositions in powder form.
Although the marketing of powdered detergent compositions packaged in cartons is common practice, this imposes constraints both on their formulation and methods of production. For example the powders must be free flowing and have an attractive appearance to the consumer, and the ingredients should not segregate during transport and storage. The products must also be safe, both for contact with the skin and in the event of accidental ingestion. In particular, the compositions should not be too highly alkaline in aqueous solution, although a degree of alkalinity is beneficial for detergent properties. When using washing machines which have a rotating drum in which the fabrics are piaced, there can also be substantial ; losses of detergent powder by retention in the dispenser and by its accumulation in the dead spaces beneath the drum, such as the drain hose, when using conventional detergent powder dosing methods. In addition, the sale of detergent compositions in powder form can introduce dosing problems, as the consumer commonly uses either too much or too little detergent powder in the washing machines for optimum detergency under the prevailing conditions.
It has been proposed previously to market detergent compositions in packages, each of which contain suitable amounts of the detergent powders for standard washing conditions. In particular, the detergent powders can be contained within bags of either water-soluble materials or water permeable materials, or they can be compressed into

cC.1012 tablet or cake form. But such packages have not met withmuch commercial success as yet, one of the problems being the difficulty of making the products strong enough for satisfactory transport and storage properties, whilst yet permitting the contents to disperse in the wash liquor very quickly during use.
According to the present invention a detergent product - comprises a particulate detergent composition contained within a closed water-insoluble bag which has a water-sensitive seal, whereby the contents of the bag aredischarged on contact of the bag with water. In practice the bags should open quickly to discharge their contents within at least five minutes and preferably within two minutes of the start of the washing process, i.e. when sufficient water has been admitted to the washing machine to immerse the bag when agitation is commenced. The best products are capable of opening and discharging their contents within about 15 seconds to one minute of commencing the washing process, whilst still being strong enough to prevent leakage through the seams during handling prior to use.
The detergent products of the invention give consumer benefits both by way of improved cost-effectiveness and in , convenience of use. In particular, by using a bag with a -water-sensitive seal, it becomes possible to use cheaper, substantially powder-impermeable materials to form the bag.
Detergent compositions can then be used in the bags with greater safety than otherwise, for example more highly alkaline materials can be used than in powders which contact the skin.
.,j,i-' 2~
cC.1012 A further advantage of the use of the products of the invention is that the detergent powders can be of higher density than usual, which decreases packaging, storage and transport costs. This can also simplify powder processing techniques, for example acce`ptable powders can be prepared entirely by simple admixture or by granulation, because a good appearance for the powders is less important for commercial acceptance of the products. There is also increased economy of use due to avoiding the dispenser residues and loss of powder in the dead spaces of washing machines, as occur with conventional powders supplied in cartons, together with closer dosage con'trol which tends to ~ improve detergency by eliminating under-dosing.
- The bags used to form the products of the invention may be constructed of paper, of woven, knitted or non-woven fabric or of plastic sheet material., The bags should be water-insoluble but can be water-permeable or non-permeable; if water-permeable, the pores should be small so that there is no substantial loss of detergent powder in transport or handling. Sheet materials which are substantially non-porous are preferred if the detergent - powder is to contain any ingredient which is sensitive to moisture in the atmosphere or which is a skin irritantO
The materials used to form the bags are required to have a high wet strength, so as not to disintegrate during the washing process. The preferred sheet material for ~ forming the bags is paper or thin non-woven fabric of `~ predominantly cellulosic material and of high wet strength, weighing about 10-60 g/sq m, such as is commonly used for ~ ~0 packaging beverage powders and other foodstuffs.

ll'~'Z~9~
cC.1012 Suitable sheet materials of this type are commercially available, for example from J.R. Crompton & Bros. Ltd of Bury, England. If the bags are to be used for detergent powder which con.ains an oxygen-liberating bleaching agent, for example sodium perborate or sodium percarbonate, ik is desirable to form the bags of sheet material made from oxidation-resistant fibres, or to treat the sheet material before or after forming the bags with a coating to improve oxidation resistance. The cellulosic fibres preferably used may be of natural or synthetic origin and may be used alone or in admixture with either natural or synthetic fibres, for example polyamide, polyacrylate, cellulose ~- acetate, polyethylene or polyacrylonitrile fibres. If ~ natural fibres are used, it is desirable to include a -~ - 15 proportion of long fibres such as manilla hemp, in order to improve the strength of the sheet material, and polymeric ~ coating is also desirable for increasing wet strength.
.~
The bags can be formed of one or more sheets or a tubular section of the sheet material, but they are , preferably made of a single folded sheet or two sheets of the material bonded together at the edges with a water-soluble sealing material. For example, the bags can be - rectangular sachets formed from-single folded sheets and - sealed on three sides so that on addition to water the seals are broken and the bags open completely to revert the single sheets of~the material of which they are ~
constructed. Alternatively, the sheets can be folded like envelopes with overlapping flaps to be sealed, which form of construction tends to be stronger than with edge seals.
The bags may also be reinforced, if desired, to decrease the risk of leakage during handling, for exaMple by adding~

cC.1012 an extra thickness of the sheet material where the bags are expected to be held or passing completely round the bags to help support the weight of detergent powder.
If desired, the sheet material used to form the bag can be marked or tagged so that it can be easily recognised `amongst the washed fabrics, for example the material may be printed with a simulated fabric pattern such as check or gingham. It can then either be discarded, or if desired it may be constructed of a suitable material to provide it with a secondary use, for example as a cleaning cloth or handkerchief.
If desired, the bags can be formed with more than one ` . separate compartment for different detergent ingredients, or the bags may be formed in a conjoined manner, for ~ 15 example in a strip to facilitate dosing of different `~ numbers of the bags as appropriate for the wash conditions.
The use of multi-compartment bags facilitates the use of detergent ingredients which interact with other ingredients in detergent compositions, whilst avoiding encapsulation or other treatment to prevent contact between such ingredients ` in a single composition.
' ~
The water-sensitive seals in the bags are most ~ conveniently formed by using a water-soluble adhesive at ; one or more edges of the bags. Suitable water-soluble adhesives can, for example,-be based on polysaccharides such as starch or dextrin, synthetic polymers such as ; polyvinyl alcohol, or alkali metal silicates. Small amounts of plasticisers, for example ethylene glycol, can be added to the water-soluble adhesives, if desired.

cC.1012 Any detergent composition in powder form can be packaged to advantage i,n the products of the invention.
Such detergent compositions are amply described in the literature, for example in "Surface Ac,tive Agents and Detergents", Volumes I and II, by Schwartz, Perry & Berch.
However, the products of the invention are advantageously used for detergent powders-containing insoluble ingredients. Specific compositions of this type which may be mentioned by way of example, are those described in UK patent No. 1,437,950, which describes detergent compositions comprising from 5 to 40% of a detergent active compound, from 10 to 75% of sodium or potassium carbonate and from 5 to 60% of finely divided - calcium carbonate. Examples of such detergent compositions which are especially adapted for use in the products of the invention are also described in British Patent Specification No. 1,583,081 in the name of Unilever Limited. Other detergent compositions comprising insoluble ingredients which are suitable for use in the products of the invention are those which comprise organic or inorganic ion-exchange materials as detergency builders, for example the sodium aluminosilicates described in UK patent applications 1,429,143, 1,473,201 and 1,473,202.
' The products of the invention are,also suited for use with the alkaline pa,rticulate detergent compositions described in the German patent application No. 2637890.
These compositions comprise from 5 to 30% of a synthetic detergent compound and from 10 to 30% of mixed sodium tripolyphosphate and alkali metal orthophosphate in the ratio of 10:1 to 1:5 parts by weight, the ~ 7 ~

a~ount of sodium tripolyphosphate being at least S% and the amount of any alkali metal pyrophosphate being no-t more than 5% of the compos it ion.
If desired, minor ingredients of the detergent connpositions, for e.~ample fluorescent agents or anti-redeposition agents such as sodium carboxymethylcellulose, may be impregnated on the bag itself for addition to the wash liquor~
- Tbe invention is illustr,ated by reference to the following Examples in which parts and percentages are by weight e~cept where otherwise indicated.
In the Examples reference will be made to the accompanying drawings, in which Figure l represents a schematic elevation of a first product according to the invention, and Figure 2 represents a schematic elevation of a - second product according to the invention.

It was found that the filled bags were strong enough not to burst readily during handling even though nearly full of the detergent powder, and there was very little dusting of the powder through the non-woven material used.
On contact with water in a washing machine the bags were - found to discharge their contents within one minute.

Compara~ive tests were undertaken in which the washing~
performance was measured for the sachet packaged products~
against the same powder dosed conventionally in the ` dispenser of a front loading automatic washing machine, and it was found that the washing results with the former were generally preferred.

It was found that there was generally similar performance for both products, but with noticeable benefits in bleachable stain removal for the sachet packaged product under conditions of use in hard (25F) water at 95C.
Example 2 Detergent bags in sachet form were made from cellulosic paper of high wet strength with the form of construction as shown in Figure 2. The bag represented in schematic elevation is formed of a single sheet of paper 5 with a longitudinal glued seam 6 and a bottom folded glued seam 7. The top flap 8 is closed by adhesive under pressure-after filling with detergent powder. This form of construction is particularly suitable for accomplishing automatically on available types of machinery.
Detergent bags of this type were filled with 90 g each of the powdered detergent composition as described above in Example l according to our copending patent application (Case C.lOll) and evaluated against the same product used , under identical washing conditions. The bags were added to washing machines on top of the fabrics to be washed, whilst the loose powder was` dosed conventionally in the washing machine dispenser. The results of the halved article tests in Miele machines using product concentrations of 0.4% in water of 25H at 60C showed a significant preference for the washing performance when using the detergent bags.
