Definitions
- bleach activator granules are produced by mixing dry particles of the activator, which is usually tetraacetylglycolurile, with inorganic salts containing water of hydration and then moistening the blend with water or a solution of granulating aid, which is selected from inorganic salts, organic binders and detergent compounds. No mixtures of such granulating aids are specifically exemplified. The granules are then coated with water-insoluble solid coating substances such as magnesium oxide.
- the process can produce granule compositions in which the presence of the disintegration aid causes substantial increase in the activity of the composition when dissolved in water at 20°C containing perborate and a detergent base in a simulation of a cold-fill system (PA 20).
- the objective of the invention here is to reduce the quantity of undissolved activator collecting in the sump of the machine by effecting rapid release of the available peracid.
- the product of the process show an increase in activity of more than 1.3 times compared to the compositions free of the granulation aid after 2 minutes of the test and an increase of more than 1.3 after 5 minutes of the test.
- the 2 and 5 minutes activities at 20°C are measured by the following test.
- the granulated composition (3g) is added to 1 litre of distilled water containing 100 ppm of calcium ions and 40g of a spray dried detergent base (ECE detergent base obtained from the Society of Dyers and Colourists, Bradford, W. Yorks), thermostatically controlled at 20°C.
- EAE detergent base obtained from the Society of Dyers and Colourists, Bradford, W. Yorks
- Sodium perborate tetrahydrate (12g) is added and the timer set to zero. Aliquots of 50 ml are taken at 2, 5 min and titrated as described above. The results are expressed as moles of peracid liberated per g of activator as a percentage of the theoretical quantity available.
- the granule disintegration aid can be any water soluble material comprising sequestering agent that will promote rupture of the granules and exposure of the activator particles to the water. It is advantageous because the granule disintegration aid has stabilising properties upon the peracid species formed on the reaction of the bleach and the activator. By using these stabilising compounds it is possible to maintain the peracid activity over an extended period in the wash as compared to compositions free of the compounds. Thus the 30 minute activity at 40°C (as defined above) can be maintained at, or close to, the 5 minute activity at 40°C.
- the disintegration aid comprises a sequestering agent or mixture of sequestering agents. It may comprise an amino carboxylic acid sequestering agent, for instance nitrilo triacetic acid or ethylene diamine tetra acetic acid or diethylene triamine penta acetic acid (or salts thereof) or a low molecular weight anionic polymer formed from ethylenically unsaturated monomers e.g. unsaturated carboxylic acid or sulphonic acid monomers, such as acrylic acid, but preferably the disintegration aid comprises a phosphonic acid sequestrant or stabiliser.
- an amino carboxylic acid sequestering agent for instance nitrilo triacetic acid or ethylene diamine tetra acetic acid or diethylene triamine penta acetic acid (or salts thereof) or a low molecular weight anionic polymer formed from ethylenically unsaturated monomers e.g. unsaturated carboxylic acid or sulphonic acid
- the disintegration aid may comprise, in addition to such sequestering agents, water-soluble inorganic salts, such as alkali metal or alkaline earth metal salts, preferably sodium, potassium calcium or magnesium salts or mixtures.
- the salts may be the water-soluble sulphates, carbonates or halides, usually chlorides, mixtures can be used. Particularly suitable examples are sodium sulphate and magnesium sulphate.
- the binder must be an organic polymeric binder that can be a natural or synthetic polymer and can be water swellable or water soluble.
- Synthetic binders include polyacrylates, polymaleates and polyvinyl pyrollidones, which may be cross linked, e.g., the cross linked polyvinyl pyrollidone sold under the trade mark Gafdis.
- the binder is a natural binder (including derivatives thereof), most preferably a starch binder, generally a starch ether, or a cellulose binder, generally a cellulose ether or ester.
- Particularly preferred binders are carboxymethyl cellulose CMC.
- the amount of granulating aid(s) will depend on the granulation aid(s) being used and on the binder and the amount of binder but is generally in the range 1 to 20%, preferably 2 to 15% and most preferably 3 to 10% by weight of the activator, binder and granulating aid(s).
- the cation should contribute from 0.165% by weight of the granule, preferably 0.3 to 2.0%, most preferably 0.4 to 1.5%.
- the product granules preferably consist substantially only of the activator, binder and disintegration aid(s)
- other components of the final detergent may be included in the process if desired in any suitable amounts.
- Preferably however such additions provide less than 10% and generally less than 5% by weight of the granules.
- One component that can usefully be included in the granules is optical brightening agent since its incorporation in the granules avoids the problems associated with incorporating it in the remainder of the detergent composition. For instance it may be damaged by the spray drying to which the remainder of the composition is generally subjected.
- Another component that can conveniently be co-granulated is an antisudsing (anti foaming) or foam stabilising agent.
- Other components that may be cogranulated are other components of detergent compositions such as surfactants, anti redeposition acids, builders, pigments or dyes and enzymes.
- the granules preferably have an average particle size of between 300 and 1500 »m, most preferably 500 to 1000 »m. Preferably substantially none of them have a size above 2000 »m and preferably not above 1700 »m. Preferably none of the granules have a size below 50 »m and most preferably none have a size below about 125 »m. Granules that are too fine are preferably separated from the granules and recycled for further granulation, often after crushing.
- a particular advantage of the invention is that the large amounts of binder that can be used minimise the risk of formation of fines.
- the resultant granules can be incorporated in conventional detergent compositions that contain a suitable bleach component that is activated by the activator.
- the preferred bleaches are peroxy compounds, especially perborates such as sodium perborate tetrahydrate but others that can be used include sodium perborate monohydrate or sodium percarbonate.
- the detergent may contain, in addition to surfactants, detergent builders and anti-redeposition aids, enzymes, anti-sudsing agents, foam stabilisers,optical brightening agents, pigments, dyes and perfumes, sequestrants, halide salts such as sodium bromide, manganese salts such as manganous sulphate and inert fillers such as sodium sulphate or silicate.
- a particular advantage of the invention is that it is not necessary to include phosphates, although they may be included if desired.
- the amount of activator, based on the total weight of the detergent may be conventional or may be less than usual, because of the increased activity. Typical amounts are 1 to 5% based on the total detergent, or 10 to 50% based on the bleach.
- the standard composition is made by the following process:- Into a suitable mixing machine is weighed: TAED 1012g CMC 56g The dry components are mixed for 3 minutes after which Water 233g is added, whilst mixing is continued, over 2 minutes. The product is then discharged and dried for 15 minutes at 60°C using a fluid bed drier.
- compositions made by these general techniques were sieved to separate a fraction of 1000 to 1700 »m and the granules were then tested for activity by the method described above.
- Granules of activator were formed using a range of conventional table disintegration aids, i.e. which are water-swellable, instead of the water-soluble disintegration aids used in the present invention.
- a process similar to that used in the reference example was used but replacing part of the binder with the disintegrant.
- the type and amount (weight percentage based on total dry ingredients) of disintegrant and PA20 values are given in the table below:
- Table 3 shows that conventional disintegration agents of the water-swellable type produce granules which have even worse PA20 values than the standard composition.
- ⁇ R% in the table is the percentage difference in stain removal as measured by reflectance from a washed swatch of stained cloth, with the value of ⁇ R% for the standard composition being given the value 0.
